Loan & EMI Calculator
Monthly repayment, total interest and a full amortisation schedule for any loan.
Loan and EMI Calculator with Amortisation Schedule
An equated monthly instalment keeps your payment constant while the split inside it shifts: early payments are mostly interest, later ones mostly principal. That is why paying a mortgage for five years can leave the balance barely dented, and why overpaying early saves disproportionately more than overpaying late.
This calculator uses the standard amortisation formula to show the monthly figure, the total interest you will pay over the term, and how the balance falls year by year. Seeing the interest total next to the loan amount is often more informative than the monthly figure alone.
Key features
- Standard EMI formula — the same calculation banks use for fixed-rate amortising loans.
- Total cost, not just the monthly figure — total interest and total repaid, side by side.
- Principal versus interest split — a visual bar showing what share of your payments is pure interest.
- Year-by-year schedule — remaining balance at each anniversary, rolled up rather than 360 unreadable rows.
- Zero-interest handling — a 0% loan divides cleanly instead of producing a division error.

How to use: Loan & EMI Calculator
- Enter the loan amount
The principal you are borrowing, before any fees that are paid separately. - Enter the annual interest rate
Use the nominal annual rate. The calculator converts it to a monthly rate internally. - Set the term in years
Longer terms lower the monthly payment but increase total interest substantially. - Review the total interest
Tick the schedule box to see how slowly the balance falls in the early years — that is where overpayments have the greatest effect.

Frequently asked questions
How is the monthly payment calculated?
EMI = P × r × (1+r)^n / ((1+r)^n − 1), where P is the principal, r the monthly interest rate (annual rate ÷ 12 ÷ 100) and n the number of months. This is the standard amortisation formula for a fixed-rate loan.
Why is so much of my early payment interest?
Interest is charged on the outstanding balance, which is at its highest at the start. As the balance falls, the interest portion shrinks and the principal portion grows — the payment stays the same but its composition flips over the term.
Does a longer term save money?
It lowers the monthly payment but raises the total cost, often dramatically. Extending a mortgage from 25 to 35 years can add more than half the original loan amount in extra interest.
Does this include fees, insurance or taxes?
No. It calculates principal and interest only. Arrangement fees, mortgage insurance, property taxes and escrow payments are separate and vary by lender and country.
