Loan Calculator

Calculate your loan repayments, total interest paid, and monthly installments


Understanding Loan Calculations

This calculator uses the standard EMI formula to compute monthly repayments. For a quick comparison, also check our EMI Calculator and Mortgage Calculator.

• How Loan Calculator Works

A loan calculator helps you estimate your monthly repayment (EMI), total interest payable, and total amount you'll repay over the loan tenure. Whether it's a home loan, car loan, personal loan, or education loan " the underlying math is the same and is based on the EMI (Equated Monthly Installment) formula used by all Indian banks and NBFCs.

Unlike simple interest loans (where interest is calculated only on principal), most bank loans use reducing balance method " meaning interest is calculated on the outstanding balance each month, which decreases as you repay.

EMI Formula (Used by All Banks)

EMI Formula EMI = P A r A (1 + r) [(1 + r) 1] P = Principal loan amount | r = Monthly interest rate (Annual rate 12 100) | n = Loan tenure in months

Worked Example

Home Loan Example

Loan Amount: 50,00,000 | Rate: 8.5% p.a. | Tenure: 20 years (240 months)

Monthly rate (r): 8.5 12 100 = 0.007083

Monthly EMI ?? 43,391

Total Payment: 43,391 A 240 = 1,04,13,840

Total Interest Paid: 1,04,13,840 50,00,000 = 54,13,840 (108% of principal!)

Frequently Asked Questions

Simple interest = P A R A T / 100 (interest stays constant). EMI loans use the reducing balance method " each month you pay interest only on the remaining principal. This results in a higher total interest payment than it might initially appear, but the monthly payment stays fixed (equated).

An amortization schedule is a complete table showing every monthly payment broken down into principal and interest components. In early EMIs, most of the payment goes towards interest. Over time, the principal component increases and interest decreases. Use our Amortization Calculator to see the full schedule.

1. Prepay: Even small lump-sum payments significantly reduce total interest. 2. Shorter tenure: A 10-year loan pays much less interest than a 20-year loan at the same rate. 3. Negotiate rate: A 0.5% lower rate on a 50L loan over 20 years saves 3-4 lakhs. 4. Larger down payment: Reduces the principal borrowed.

Most banks in India require a CIBIL score of 750 or above for home and personal loans at the best interest rates. Scores between 650"749 may still get loans but at higher rates. Below 650, loan approval becomes difficult. Maintain timely payments on existing credit cards and loans to improve your score.

What is a Loan Calculator?

A loan calculator helps you determine monthly payments (EMI), total interest payable, and the total amount you will pay over the life of a loan. It works for home loans, car loans, personal loans, education loans, and any fixed-rate amortizing loan.

Loan EMI Formula

EMI = P × r × (1+r)n / ((1+r)n − 1)

Where P = loan principal, r = monthly interest rate, n = total number of monthly installments.

Total Interest = (EMI × n) − P

How to Use

  1. Enter loan amount — The total principal you want to borrow.
  2. Enter interest rate — Annual rate offered by your bank.
  3. Enter tenure — Loan duration in months or years.
  4. Click Calculate — View EMI, total interest, and amortization schedule.

Example: ₹10 Lakh at 9% for 5 Years

EMI: ₹20,758 | Total Interest: ₹2,45,500 | Total Payment: ₹12,45,500

Frequently Asked Questions

What is the difference between flat rate and reducing balance?

Flat rate calculates interest on the original principal throughout the tenure. Reducing balance (used by most banks) calculates interest only on the outstanding balance, making it cheaper. This calculator uses the reducing balance method.

How does tenure affect total interest?

Longer tenure means lower EMI but significantly higher total interest. A ₹10 lakh loan at 9% costs ₹2.45L interest over 5 years but ₹7.28L over 15 years.

Can I reduce my loan interest?

Yes. Make prepayments when possible, choose a shorter tenure, negotiate a lower interest rate, and maintain a high credit score for better loan terms.
