📊 What is the Interest Savings Calculator and How Does It Work?

Extra EMI payments directly reduce the outstanding principal, with all future interest computed on the reduced balance. Even small additional payments early in the loan create compounding savings over the remaining tenure.

Formula

Interest saved = Total interest (minimum EMI) – Total interest (minimum + extra)  |  Months saved = Original payoff months – New payoff months

❓ Frequently Asked Questions

How much can extra EMI save?▼

Even ₹2,000 extra/month on a ₹30L home loan at 8.5% can save ₹4–5 lakh in total interest.

Should I pay extra EMI or invest?▼

Loan rate greater than investment return: pay extra EMI. Home loan at 8.5% vs expected equity return at 12%: investing may win.

When does extra payment have most impact?▼

In the early years — when the interest component of your EMI is highest. Extra payments in years 1–5 save the most.

Can I pay one extra EMI per year?▼

Yes. Making 13 EMIs instead of 12 per year can cut 3–4 years from a 20-year home loan.

Monthly extra payments vs lump sum?▼

Lump sum immediately reduces principal and saves more. Monthly extra payments are more practical for most people.
