Overview

How EMIs actually work

An equated monthly installment keeps your payment fixed, but the split shifts over time: early payments are mostly interest, later ones mostly principal. The amortization schedule makes this visible, which is why two loans with the same EMI can cost very different amounts in interest.

Guide

Detailed guide

The power of prepayment

Because interest is charged on the outstanding balance, a lump sum paid early removes interest from every future month at once. The calculator quantifies this, often a single prepayment saves far more than its size suggests and pulls your debt-free date forward by months or years.

Fixed vs floating rates

A fixed rate locks your EMI for predictability; a floating rate moves with the market and can rise or fall. Modeling both here helps you see how sensitive your payment is to rate changes before you commit.

FAQ

Frequently asked questions

How do I calculate my loan EMI?+

Enter your loan amount, annual interest rate, and loan tenure (months or years). The calculator applies the EMI formula: EMI = P × r × (1+r)^n / ((1+r)^n - 1), where P = principal, r = monthly rate, n = months.

What is an amortization schedule?+

An amortization schedule shows every monthly payment of your loan, how much goes to interest vs. how much reduces your principal. Early payments are mostly interest; later payments are mostly principal.

How much do prepayments save on a home loan?+

Prepayments directly reduce your outstanding principal, dramatically cutting total interest. On a $300,000 mortgage at 7% for 30 years, a $10,000 prepayment in year 1 can save over $30,000 in interest and cut 2-3 years off the loan.

What is the difference between a fixed and floating interest rate?+

A fixed rate stays the same for the entire loan term, making EMIs predictable. A floating rate changes with market conditions (like RBI/Fed rates), so your EMI can go up or down. Fixed rates are safer; floating rates can be lower initially.

How do I reduce my loan EMI?+

Three options: 1) Increase the loan tenure (longer repayment period, smaller EMI but more total interest), 2) Make a larger down payment to reduce the principal, 3) Negotiate a lower interest rate by improving your credit score before applying.

What is the Rule of 72 for loans?+

The Rule of 72 estimates how long it takes for debt to double at compound interest. Divide 72 by the annual interest rate: at 8% interest, debt doubles in 9 years (72 ÷ 8 = 9). This shows why paying off high-interest debt quickly is so important.

How much interest will I pay over the life of the loan?+

Enter the loan amount, interest rate and term to see the monthly payment plus the total interest paid over the full term, so you can compare offers by true cost, not just the monthly figure.

How much can I save by making extra payments?+

Add an extra monthly or one-time payment to see how much sooner the loan is paid off and how much total interest you save, which is often thousands over a long loan.

Can I see a full amortization schedule?+

Yes. The calculator breaks each payment into principal and interest across the whole term, so you can see how the balance falls month by month and when the crossover happens.

How do prepayments save money?+

Interest accrues on the remaining balance, so paying extra early erases interest on all the months that follow, the calculator shows exactly how much.
