Amortization schedule calculator
Updated November 6, 2026. Runs entirely in your browser; nothing you type is sent anywhere.
Enter a principal, annual rate, term in years, and an optional extra monthly payment. You'll see a monthly principal+interest sketch, a short early-month table, total interest, and one calm sentence you can adapt. This is arithmetic only—not a lender schedule, not a loan quote, and not financial advice.
How to use the number
- Ask your lender for the real amortization and escrow figures; re-run with those inputs for a closer sketch.
- For a payment-only sketch without a table, see the free loan payment calculator or mortgage payment calculator. For refinance break-even, see the refinance calculator.
- When the hard part is the bill, landlord, raise, or offer call that funds the payment, use a script.
What to say when cash or housing is the bottleneck
Knowing the schedule sketch is step one. Saying the next line on a bill, landlord, raise, or offer call is where people freeze. The Bills Kit ($19) gives word-for-word lines for bill and landlord moments plus Call Mode. If pay is the lever that makes the payment realistic, see the Offer Kit ($29). One-time purchase, 14-day refund on both.

How does this amortization schedule sketch work?
It uses the standard payment formula M = P × r(1+r)^n / ((1+r)^n − 1), then walks month by month: interest = balance × r, principal = payment − interest, new balance = balance − principal. Optional extra monthly payments are applied to principal. The table shows the first months and a summary; it is not a full lender statement.
Is this a loan quote or financial advice?
No. It is simple arithmetic on the numbers you enter, plus a sample sentence you can adapt. It is not a quote, pre-approval, tax advice, or a substitute for a qualified professional or your lender.
What if my rate is zero?
If the annual rate is zero, the monthly payment sketch is principal ÷ number of months, and each month is all principal.
Why does the table stop early?
This page shows a short preview of early months plus totals so it stays readable in the browser. Re-run with your real principal, rate, and term, then confirm against your lender amortization for the full schedule.
