Extras go towards principal with the scheduled payment. Yearly extras start at payment 12; a one-time extra after payoff has no effect. The regular payment is estimated from the balance and remaining term. No recasting, escrow or prepayment penalty is included.

Monthly schedule

OpenStax: loan amortisation: https://openstax.org/books/principles-finance-2e/pages/8-3-loan-amortization explains how regular payments reduce a loan. With monthly rate r and n payments, payment = principal × r / (1 − (1 + r)^−n); at zero interest, divide principal by n.

Each month adds interest to the opening balance before applying the regular payment and extras. The final payment is capped at the amount owed. Amounts are calculated at full precision and displayed to cents.

Dates and extra principal

The first scheduled payment is payment 1. Later payments fall on the same day of the month, clamped to month-end when necessary. Dates assume uninterrupted monthly payments.

CFPB: prepayment penalties: https://www.consumerfinance.gov/ask-cfpb/what-is-a-prepayment-penalty-en-1957/ explains why loan terms matter when paying early. This model excludes penalties, escrow and mortgage recasting.

How to use it

  1. Enter your remaining mortgage balance, rate and term.
  2. Add monthly, yearly or one-time extras and choose the first payment date.
  3. Read the new payoff date and open the amortisation table.

Frequently asked questions

When does the yearly extra payment happen?

At payment 12, 24, 36 and each later multiple of 12. A one-time payment uses the payment number you enter.

Does paying extra lower my regular payment?

The calculation keeps the regular principal-and-interest payment unchanged and shortens the term. It does not model a mortgage recast.

What if my mortgage has a prepayment penalty?

This estimate does not deduct penalties. Check your loan terms and how the servicer applies extra principal before relying on the savings.
