  • SBLOC vs mortgage vs cash calculator

    Compare funding a down payment from cash, by selling stock, or with a securities-backed line of credit — capital-gains tax, interest, and 10-year net position side by side.

  • SBLOC vs HELOC after-tax calculator

    Compare the after-tax cost of a HELOC and an SBLOC for home improvement, a second home, a business, or personal use, including when HELOC interest is deductible.

  • Cost-to-sell stock calculator

    The all-in tax cost of selling appreciated stock — federal long-term capital gains, the 3.8% NIIT, and state tax — versus borrowing against the position instead.
