Mortgage Suite

Read your amortization schedule, test what an extra payment does, check the break-even on a refinance, and see the payoff-vs-invest math. Every figure is calculated from the numbers you enter. Nothing here is an offer, an approval, or a recommendation.

Refinance break-even

Pay down vs invest

Take the same monthly surplus and compare two paths on your own numbers: throw it at the mortgage, or invest it over the remaining term.

This tool is for educational and personal-planning purposes only. It is not financial, tax, or investment advice, not a loan offer or commitment, and not a recommendation to refinance, pay down, or invest. Every figure is an estimate generated from the inputs you provide. Rates, costs, and returns you enter are your own assumptions and are not supplied or endorsed here. Consult your own lender, accountant, and financial professional before acting.
