Amortization Schedule Calculator
Estimate loan payments, total interest, payoff date, and a full amortization schedule. Model mortgages, car loans, personal loans, or any fixed-rate installment loan. Add extra monthly payments or annual lump sums to see how much interest and time you could save.
Burrow Tip: Don’t only look at the required payment. Compare the full interest cost, payoff timeline, and the impact of even small extra payments.
A modest recurring extra payment can cut years off a loan and materially reduce total interest paid.

Escrow and housing costs (optional)
Comparison scenario (optional)
Burrow Tip: Comparison mode is most useful for testing refinance-style decisions, shorter terms, or “what if I paid extra?” scenarios.

How to use these results
A loan payment tells only part of the story. The more important questions are: How much interest will I actually pay? and How fast can I reduce principal?
- Compare term lengths: a longer term lowers the payment but usually raises total interest substantially.
- Test extra payments: recurring extra payments often deliver an outsized reduction in interest cost.
- Look at all-in housing cost: principal and interest may fit your budget, but taxes, insurance, and HOA can change affordability.
- Use the schedule: the amortization table shows exactly how much of each payment goes to interest versus principal.
This tool assumes a fixed-rate fully amortizing loan and does not model variable rates, late fees, PMI, closing costs, or refinance fees unless you add them separately.
