    Share assumptions, never dollar amounts

    Links include eligible rate, term or frequency assumptions only. Dollar amounts are never included. Recipients must enter their own amounts; the link will not reproduce your full financial scenario.

    HOW IT WORKS

    Calculation method

    Calculate a monthly amortizing payment using the selected equivalent rate. Ordinary biweekly payments are monthly × 12/26; accelerated payments are monthly/2. Simulate balances with equivalent 26-period annual rates and capped final payments.
