What is the Private Client concession worth in dollar terms?

On a $1M draw held for five years at SOFR 4.50%, a 50 bp concession saves approximately $25,000 in cumulative interest. On a $2M draw over the same window, the savings climb to roughly $50,000. The Private Client threshold (typically $1M+ in qualifying Schwab and Schwab Bank assets) is meaningfully lower than the $5M+ thresholds at most private banks, which is why the concession often closes the gap between Schwab PAL and Morgan Stanley's negotiated Liquidity Access Line pricing.

Should I use a PAL calculator before or after running the jumbo mortgage math?

Run both in parallel, then reconcile. The conventional jumbo is fully deductible up to the $750K acquisition cap per IRC Section 163(h)(3), which makes the after-tax effective rate substantially lower than the headline. The PAL is non-deductible. The PAL wins on portions of the purchase above the $750K cap, on down payment financing where the deduction does not apply, and on scenarios where avoiding a capital gains realization has higher after-tax value than the deduction. Both calculations are needed to size the spread.

Pledged Asset Line (PAL) Mortgage Calculator: Schwab Rates

By Tyler Singletary · May 24, 2026

A general SBLOC calculator takes a single rate input and runs the math from there. That works for back-of-envelope sizing. It does not work for a Schwab Pledged Asset Line, where the rate depends on which tier your line size falls into, whether you qualify for Schwab Bank Private Client, and what blended advance rate Schwab assigns to your specific portfolio composition. A PAL is structurally identical to a generic SBLOC but priced on a venue-specific schedule, and the pricing differences are large enough to change the financing decision.

This guide is the calculator companion to the Schwab PAL explainer. It walks through the inputs a PAL-specific calculator needs that a generic SBLOC tool does not, runs a worked $1M draw at Schwab Private Client pricing, and shows why the published rate is the ceiling for HNW clients rather than the floor. For the broader HNW calculator stack, see the pillar mortgage calculator for high net worth buyers.

Rate data current as of May 24, 2026. SOFR moves daily per the New York Fed. Schwab's spread schedule and Private Client concession structure change periodically. Verify any rate directly with a Schwab Bank lending specialist before sizing a draw.

What a PAL Calculator Needs That a SBLOC Calculator Does Not

A Schwab PAL calculator needs three inputs a generic SBLOC tool collapses or omits: the tiered spread schedule, the Private Client concession, and the per-asset-class advance rate. Per the Schwab Pledged Asset Line product page, the published spread ranges from SOFR + 2.25% on the largest tiers to SOFR + 3.75% on lines under $250K. A single-rate calculator misses 150 bp of pricing reality.

The first input is the tiered spread. Schwab prices PAL spreads in five bands by line size: under $250K at SOFR + 3.75%, $250K to $1M at SOFR + 2.75%, $1M to $5M at SOFR + 2.25%, $5M to $25M at SOFR + 1.75%, and above $25M as negotiated. A calculator that asks for "the SBLOC rate" as a single number forces the user to look up which tier applies before the math runs. The PAL-specific tool should take line size as the input and derive the spread.

The second input is the Private Client concession. Schwab Bank Private Client status, typically $1M or more in qualifying Schwab and Schwab Bank assets, unlocks a 25 to 50 basis point concession on top of the published schedule. The threshold is materially lower than the $5M to $10M minimums at most private banks, which is part of why Schwab PAL pricing competes with relationship-priced products at Morgan Stanley and Goldman. A calculator that ignores the concession overstates the all-in rate by 25-50 bp for the majority of HNW Schwab clients.

The third input is the blended advance rate against the pledged portfolio. Schwab assigns advance rates per asset class: 85-95% on Treasuries, 65-75% on diversified equity ETFs, 50-70% on large-cap individual stocks, 30-50% on concentrated single positions, and 0% on restricted shares. The blended rate determines the maximum line size your collateral supports. A generic SBLOC calculator that assumes a flat 50% margin requirement misses the per-asset-class detail that drives Schwab's actual underwriting.

How Does Schwab's Tiered Rate Schedule Work?

Per the Schwab Pledged Asset Line product disclosures, the tiered schedule rewards larger lines materially: the spread drops 50-100 basis points each time the line crosses into a higher tier, and the lower spread applies to the entire balance rather than the incremental amount. At SOFR 4.50% from the New York Fed reference rates, the published all-in rate ranges from 6.25% on the $5M to $25M tier to 8.25% on the under-$250K tier.

Line size tier	Published spread	All-in at SOFR 4.50%	Private Client (25 bp)
Under $250K	SOFR + 3.75%	8.25%	8.00%
$250K to $1M	SOFR + 2.75%	7.25%	7.00%
$1M to $5M	SOFR + 2.25%	6.75%	6.50%
$5M to $25M	SOFR + 1.75%	6.25%	6.00%
Over $25M	Negotiated	Variable	Variable

The tier-jump arithmetic is the most consequential output of a PAL calculator. Going from a $750K line at SOFR + 2.75% (7.25% all-in) to a $1.0M line at SOFR + 2.25% (6.75% all-in) saves 50 basis points on the entire balance, not just the incremental $250K. On a five-year carry at $1M average outstanding, the tier jump is worth roughly $25,000 in cumulative interest. The calculator should flag any line size within $50K of a tier boundary so the user can evaluate whether bumping into the next band is worth the marginal capital commitment.

Why the Private Client concession matters more than rate shopping

The 25-50 bp Private Client concession is automatic once the qualifying-asset threshold clears, but it is rarely surfaced on a calculator that takes a single rate input. The concession applies to the entire balance for the life of the line. On a $1M draw held five years, a 25 bp concession saves about $12,500; a 50 bp concession saves about $25,000. The PAL calculator should ask whether the client qualifies and apply the concession to the tier-derived spread before computing the all-in rate.

What Inputs Does a Worked PAL Calculation Require?

A complete PAL calculator needs seven inputs to produce an all-in carry cost and a maintenance LTV projection. Per FINRA's Securities-Backed Lines of Credit Investor Alert, the maintenance LTV math is the most consequential input for SBLOC safety, more so than the rate. The seven inputs map directly to the worked example below.

The seven inputs the tool needs:

Pledged portfolio market value (e.g., $3,000,000)
Portfolio composition by asset class (for blended advance rate)
Requested line size (drives the tier)
Initial draw amount (drives initial LTV)
Private Client status (yes/no, drives the concession)
Current SOFR (rate basis, sourced from FRBNY daily)
Maintenance LTV threshold (typically 70% on diversified collateral)

From those seven inputs the calculator derives the blended advance rate, the maximum supportable line size, the tier-based published spread, the Private Client-adjusted spread, the all-in rate, the annual carry on the drawn balance, the initial LTV, and the portfolio drawdown tolerance before a call.

Worked example: $1M PAL draw at Schwab Private Client

Assume a buyer with a $3,000,000 Schwab brokerage account, composed of 65% diversified ETFs, 25% large-cap stocks, and 10% Treasury ETFs. The buyer is funding a $2,500,000 home purchase with 20% down ($500K), has $250K in cash savings, and qualifies for Schwab Bank Private Client status via the $3M relationship.

Blended advance rate. 65% at 70% + 25% at 60% + 10% at 90% = 45.5% + 15% + 9% = 69.5% blended.

Maximum line size. $3M times 69.5% equals roughly $2.09M of available line capacity.

Requested line. $1.0M. The buyer draws $250K of it at closing to fund the gap above the $250K in cash savings, hitting the $500K down payment in full.

Tier and spread. $1.0M line lands in the $1M-$5M band: published SOFR + 2.25%. Private Client concession of 25 bp brings it to SOFR + 2.00%. At SOFR 4.50%, the all-in rate is 6.50%.

Annual carry. $250K balance times 6.50% = $16,250 of interest per year. Compared to the non-Private-Client published rate of 7.25% on the same draw under the prior tier (which would price at $18,125), the Private Client concession saves $1,875 per year on this specific draw, or roughly $9,375 over five years.

Initial LTV and drawdown tolerance. $250K against $3M is 8.3% initial LTV. Against a 70% maintenance threshold, tolerance is 1 minus (8.3% / 70%) = 88%. The portfolio could drop 88% before triggering a call. Even a 2008-level 45% drawdown leaves the LTV at 15%, deeply inside the safe zone.

How Does the PAL Calculator Differ From a Generic SBLOC Tool?

The most visible difference is the rate: a generic SBLOC calculator that asks for one rate input cannot model Schwab's tier-jump dynamics or the Private Client concession. Per the SEC Securities-Based Lending Investor Bulletin, pricing across SBLOC venues varies by 100-200 basis points on the same nominal line size. A PAL-specific calculator captures Schwab's portion of that range; a generic tool flattens it to a single user-supplied rate.

Three concrete differences in calculator behavior:

Difference one: tier-aware rate derivation. The PAL calculator takes line size as the input and derives the spread from Schwab's published schedule, then applies the Private Client concession if applicable. The generic SBLOC calculator takes the all-in rate as the input and trusts the user to look it up. For a buyer comparing Schwab against IBKR Pro or Morgan Stanley LAL, the PAL tool's tier logic surfaces the 50-100 bp difference between a $750K line and a $1M line that the generic tool would miss.

Difference two: per-asset-class advance rates. The PAL calculator takes portfolio composition by asset class and computes the blended advance rate against Schwab's published per-class schedule. The generic SBLOC calculator typically uses a flat 50% margin assumption, which understates capacity for diversified portfolios (Schwab supports 70%+ on most diversified mixes) and overstates capacity for concentrated portfolios (Schwab drops to 25-50% on concentrated single positions). The difference can change the maximum line size by 30-50%.

Difference three: maintenance LTV at Schwab's specific threshold. Schwab's standard maintenance LTV is 70% on diversified collateral, but the actual threshold appears in the loan agreement and can vary based on portfolio composition. The PAL calculator should default to 70% and allow the user to override based on their signed agreement. The generic SBLOC tool often hardcodes a single maintenance LTV that may not match the venue.

For the deeper structural comparison between the two, see the SBLOC mortgage calculator spoke and the venue-agnostic SBLOC vs HELOC after-tax tool.

When Does the PAL Output Argue Against the Conventional Jumbo?

Per IRS Publication 936, the home mortgage interest deduction caps acquisition indebtedness at $750,000, which means a jumbo above the cap has a non-deductible portion that compounds quickly. For a HNW buyer purchasing above the cap, the PAL calculator's non-deductible output often beats the jumbo's after-tax effective rate on the marginal dollar above $750K, even though the headline PAL rate looks worse than the headline jumbo rate.

The reconciliation math for a buyer at 37% federal + 6.85% state (NY):

A 6.85% jumbo on the first $750K of principal has an after-tax effective rate of roughly 3.70%, because the deduction at 46% combined marginal saves 3.15 points on the headline. The same 6.85% jumbo on the portion above $750K has an after-tax effective rate of 6.85%, because the deduction does not apply. A 6.50% Schwab PAL (Private Client pricing, $1M-$5M tier) is non-deductible across the entire balance, with an after-tax rate of 6.50%.

On a $2.4M jumbo, only $750K (31.25%) gets the deduction. The blended after-tax effective rate is roughly 5.86%. The PAL at 6.50% loses by 64 bp on a like-for-like rate comparison, but wins on three margins the headline rate misses: it avoids the cap-gains realization on any portion of the down payment that would otherwise require liquidating taxable holdings, it preserves the compounding on the pledged portfolio, and it stays in place beyond the conventional refi horizon without origination fees.

For the explicit hybrid comparison against the piggyback structure, see the piggyback vs SBLOC calculator. For the venue-specific essay on when Schwab PAL beats both IBKR margin and a jumbo on after-tax cost, see the companion post on the Schwab Pledged Asset Line for a home purchase.

For HNW buyers whose W-2 income alone does not clear the jumbo DTI cap but who would prefer to keep the portfolio liquid (not pledged) and pursue a conventional mortgage instead of a portfolio-financed line, the asset depletion mortgage calculator spoke covers the alternative path: a $4M eligible portfolio at a 70% haircut divided by 360 months adds roughly $7,778 of qualifying monthly income to a standard jumbo DTI numerator, often enough to clear the conventional underwriting standard without ever putting the brokerage account at risk of a maintenance call.

What Are the Most Common Calculator Mistakes?

The three most common mistakes in a HNW buyer's PAL calculation are using the published rate without asking for a concession, ignoring the maintenance LTV math entirely, and assuming SBLOC interest is deductible. Each can swing the financing decision by tens of thousands of dollars over a multi-year carry. Per the FINRA Securities-Backed Lines of Credit alert, these are the precise errors regulators flag in investor complaints.

Mistake one: using the published rate without asking for the concession. The 25-50 bp Private Client concession is automatic for qualifying clients but rarely volunteered in the first quote. On a $1M draw over five years, the gap between the published rate and the Private Client rate is $12,500 to $25,000 in cumulative interest. The calculator should default to applying the concession when the user indicates qualifying asset levels, and the user should confirm the concession appears on the live quote from the Schwab banker before signing.

Mistake two: ignoring maintenance LTV. A PAL calculator that outputs only the rate and the annual carry misses the most consequential safety metric. Initial LTV of 25-30% gives the buyer tolerance for a 2008-level drawdown without a call. Initial LTV of 60%+ gives tolerance for only a normal correction. The calculator must surface the drawdown tolerance prominently, and the buyer should size the draw based on that tolerance rather than maxing the available line.

Mistake three: assuming PAL interest is deductible. A PAL is secured by the portfolio, not the home, and therefore does not qualify as home acquisition indebtedness under IRC Section 163(h)(3). The interest is generally non-deductible personal interest. Sophisticated tracing structures can convert it to deductible investment interest under IRC Section 163(d) and Publication 550, but only on documented investment-purpose draws. The default calculator assumption should be fully non-deductible.

Frequently Asked Questions

What inputs does a Schwab PAL calculator need that a generic SBLOC calculator does not?

Three venue-specific inputs. First, Schwab's tiered spread schedule (SOFR + 2.25% to 3.75% by line size), not a single rate. Second, the Schwab Bank Private Client concession (25-50 basis points for clients with $1M+ in qualifying assets). Third, the blended advance rate against Schwab's per-asset-class schedule, which differs from the generic 50% margin assumption.

What is the Schwab PAL rate for a $1M draw in 2026?

For a non-priority client, the published spread is SOFR + 2.25% on the $1M to $5M tier, which equals roughly 6.75% all-in at SOFR 4.50%. Schwab Bank Private Client status (typically $1M+ in qualifying assets) unlocks a 25-50 bp concession, bringing the all-in rate to roughly 6.25% to 6.50%. Always confirm the live quote with a Schwab Bank lending specialist.

How does the maintenance LTV affect the PAL calculator output?

Maintenance LTV defines the threshold at which a margin call triggers, typically 70% on diversified collateral per Schwab's standard agreement. The calculator should derive the drawdown tolerance: tolerance equals 1 minus (initial LTV divided by maintenance LTV). A $250K draw against a $3M portfolio is 8.3% initial LTV, with tolerance for an 88% drop before a call.

Is PAL interest tax-deductible when used for a home purchase?

Generally no. A PAL is secured by the investment portfolio, not by the home, so it does not qualify as home acquisition indebtedness under IRC Section 163(h)(3) per IRS Publication 936. Without a sophisticated tracing structure that converts the interest to deductible investment interest under IRC Section 163(d), PAL interest funding a personal residence is non-deductible personal interest.

How does a PAL calculator differ from a SBLOC calculator at Fidelity or IBKR?

The math structure is identical (spread over SOFR, advance rate against pledged assets, maintenance LTV trigger), but the rate-schedule inputs are venue-specific. Schwab publishes a tiered schedule with Private Client concessions. IBKR Pro prices a flat formula 50-150 bp below Schwab. Morgan Stanley operates on a relationship-pricing model where the published rate is rarely what HNW clients pay.

Frequently asked questions

What inputs does a Schwab PAL calculator need that a generic SBLOC calculator does not?: Three venue-specific inputs. First, Schwab's tiered spread schedule (SOFR + 2.25% to 3.75% by line size), not a single rate. Second, the Schwab Bank Private Client concession (25-50 basis points for clients with $1M+ in qualifying assets). Third, the blended advance rate against Schwab's per-asset-class schedule, which differs from the generic 50% margin assumption. A generic SBLOC calculator that takes one rate input understates the pricing range by 100-200 basis points across Schwab's tiers and ignores the Private Client concession entirely.
What is the Schwab PAL rate for a $1M draw in 2026?: For a non-priority client, the published spread is SOFR + 2.25% on the $1M to $5M tier, which equals roughly 6.75% all-in at SOFR 4.50%. Schwab Bank Private Client status (typically $1M+ in qualifying assets) unlocks a 25-50 bp concession, bringing the all-in rate to roughly 6.25% to 6.50%. The published schedule is the ceiling for HNW clients, not the floor. Always confirm the live quote with a Schwab Bank lending specialist before sizing the draw.
How does the maintenance LTV affect the PAL calculator output?: Maintenance LTV defines the threshold at which a margin call triggers, typically 70% on diversified collateral per Schwab's standard agreement. The calculator should derive the drawdown tolerance from initial LTV and maintenance LTV: tolerance equals 1 minus (initial LTV divided by maintenance LTV). A $250K draw against a $3M portfolio is 8.3% initial LTV, with tolerance for an 88% drop before a call. A $1.3M draw against the same portfolio is 43% LTV, with tolerance for only a 39% drop.
Is PAL interest tax-deductible when used for a home purchase?: Generally no. A PAL is secured by the investment portfolio, not by the home, so it does not qualify as home acquisition indebtedness under IRC Section 163(h)(3) per IRS Publication 936. Without a sophisticated tracing structure that converts the interest to deductible investment interest under IRC Section 163(d) and Publication 550, PAL interest funding a personal residence purchase is non-deductible personal interest. Calculator outputs should model PAL interest as fully non-deductible by default for after-tax comparisons against a conventional jumbo.
What is the Private Client concession worth in dollar terms?: On a $1M draw held for five years at SOFR 4.50%, a 50 bp concession saves approximately $25,000 in cumulative interest. On a $2M draw over the same window, the savings climb to roughly $50,000. The Private Client threshold (typically $1M+ in qualifying Schwab and Schwab Bank assets) is meaningfully lower than the $5M+ thresholds at most private banks, which is why the concession often closes the gap between Schwab PAL and Morgan Stanley's negotiated Liquidity Access Line pricing.
How does a PAL calculator differ from a SBLOC calculator at Fidelity, IBKR, or Morgan Stanley?: The math structure is identical (spread over SOFR, advance rate against pledged assets, maintenance LTV trigger), but the rate-schedule inputs are venue-specific. Schwab publishes a tiered schedule with Private Client concessions. IBKR Pro prices a flat formula 50-150 bp below Schwab. Morgan Stanley operates on a relationship-pricing model where the published rate is rarely what HNW clients pay. A general SBLOC calculator with one rate input cannot model these venue differences without the user manually computing the all-in rate first.
Should I use a PAL calculator before or after running the jumbo mortgage math?: Run both in parallel, then reconcile. The conventional jumbo is fully deductible up to the $750K acquisition cap per IRC Section 163(h)(3), which makes the after-tax effective rate substantially lower than the headline. The PAL is non-deductible. The PAL wins on portions of the purchase above the $750K cap, on down payment financing where the deduction does not apply, and on scenarios where avoiding a capital gains realization has higher after-tax value than the deduction. Both calculations are needed to size the spread.
