Can I use this calculator for a mortgage I already have?

Yes, you can model your existing loan by entering your current principal balance, interest rate, and remaining term, then add extra payments to see how they affect your payoff date and interest savings.

What is the difference between monthly and accelerated bi-weekly payment frequencies?

Accelerated bi-weekly splits your monthly payment in half and pays it every two weeks, resulting in one extra full payment per year, which typically shortens the loan term and reduces total interest compared to standard monthly payments.

Does the calculator include property taxes or insurance in the results?

No, the tool focuses on principal and interest calculations only; property taxes, homeowners insurance, and PMI are not factored into the payoff schedule or total payment figures.

How accurate are the interest savings shown when I add extra payments?

The interest savings are calculated based on the additional payments applied to the principal according to the amortization schedule; actual savings may vary depending on your lender's specific terms and payment processing.

About this tool

What Mortgage Payoff Calculator does

The Mortgage Payoff Calculator on Omni Calculator lets users model repayment schedules for both existing and new mortgage loans. By inputting the mortgage amount, interest rate, and term length, the tool generates a full amortization schedule showing the payoff date, monthly payment, total number of payments, and total interest paid. A key feature is the ability to add extra periodic or one-time payments, which instantly updates the results to show how additional payments shorten the loan term and reduce total interest costs. The interface supports various payment frequencies—monthly, bi-weekly, and accelerated options—and allows users to select the interest capitalization method relevant to their region, such as semi-annually for Canada or monthly for the US and UK. The results section clearly displays the original schedule alongside any modified schedule with extra payments, making it easy to compare scenarios side-by-side.
