Loan Amortization Calculator
Loan Amortization — it builds an amortisation schedule from the reducing-balance EMI E = P·r·(1+r)^n / ((1+r)^n − 1), splitting each instalment into interest (balance × monthly rate) and principal. This page runs that same calculation on your numbers, in your browser: no signup, no uploads, nothing stored.
Loan Amortization Calculator turns your loan amount, annual interest rate and loan term into a clear figure with the supporting breakdown using standard financial formulas. The maths runs locally, so nothing you enter leaves the page.
About this calculator
Get loan amortization right and the rest of the task gets easier. It builds an amortisation schedule from the reducing-balance EMI E = P·r·(1+r)^n / ((1+r)^n − 1), splitting each instalment into interest (balance × monthly rate) and principal. It matters any time money changes value over time — savings, loans, investments, prices and pay all reduce to these relationships. On a 100,000 loan at 12% (1%/month), the first EMI of 8,884.88 splits into 1,000 interest and 7,884.88 principal; the interest share falls each month. The tool above does the same computation in your browser — free, private, nothing stored.

FAQ
What is an amortization schedule?
It is a month-by-month breakdown showing how each payment splits between interest and principal, and how the balance falls to zero over the term.
Why is early interest higher than principal?
Interest is charged on the outstanding balance, which is largest at the start. Early payments are mostly interest, and the principal portion grows over time.
How many rows does this show?
It shows the EMI and totals plus the first 12 months of the schedule, with a note of how many months remain for longer loans.
Does the Loan Amortization Calculator send my data to a server?
No. The Loan Amortization Calculator runs entirely in your browser — your inputs never leave your device, and nothing is uploaded or stored.
