Loan Amortization Calculator
Work out the monthly payment on a fixed-rate loan and see how every payment splits between principal and interest — with the total interest and a full repayment schedule.
These results are an estimate for planning only — not financial, tax or legal advice. Real loan offers depend on your lender’s rate, fees and terms, so confirm the numbers before you commit.

FAQ
How is the monthly payment worked out?
It uses the standard amortization formula, so the same fixed amount every month clears the whole loan by the end of the term. A higher rate or a longer term adds to the total interest, while a shorter term raises the monthly payment but cuts the interest you pay overall.
What does the amortization schedule show?
Each payment is split into interest, charged on the balance you still owe, and principal, the rest that actually reduces the balance. Early on most of the payment is interest; as the balance falls, more goes to principal every month until it reaches zero.
Does it include taxes, insurance or extra payments?
No — it covers principal and interest at one fixed rate. A real mortgage payment can also carry property tax, insurance and lender fees, and paying more than the scheduled amount would clear the loan earlier than shown here.
Can I rely on this for a real loan?
Use it to compare options and understand the numbers, not as advice. The final payment is nudged by a few cents so the balance ends exactly at zero, and your lender’s rate, rounding and fees may differ — confirm with them before you commit.
