What is a Home Loan Calculator?
A Home Loan Calculator estimates the monthly EMI, total interest and total repayment on a housing loan from the amount, annual interest rate and tenure you enter. This page also has modes for a rough eligibility check, prepayment, interest cost and balance transfer, so you can compare scenarios before you talk to a lender.
The figure is an estimate. Sanction amount, rate type and fees come from the bank or housing finance company after their own checks.
What the 5 modes do
- Home loan — EMI, total interest and total payment for the tenure you choose.
- Eligibility — a planning range from income and existing EMIs. Credit score, age, property and lender policy still decide the offer.
- Prepayment — how an extra principal payment can change interest or remaining years under the model.
- Interest — interest over the full term, separate from the amount borrowed.
- Balance transfer — a comparison if you move the outstanding balance to a lower rate. Transfer costs can reduce the saving.
Tip: On a 15–25 year home loan, total interest can be close to, or higher than, the principal. Always read EMI and total interest together.
How to use it
- Choose the mode (home loan, eligibility, prepayment, interest or balance transfer).
- Enter the loan amount, or the outstanding balance if you are testing a transfer.
- Enter the annual interest rate.
- Enter tenure in years.
- Read monthly EMI, total interest and total payment.
- Shorten the tenure by a few years and compare the new EMI with the new total interest.
EMI formula
E = P × r × (1 + r)n / [(1 + r)n − 1]
- E — monthly EMI
- P — principal
- r — monthly rate (annual rate ÷ 12 ÷ 100)
- n — months (years × 12)
In the early years a larger share of each EMI is interest. Later years carry more principal. That is normal on a reducing-balance home loan. Processing fee, legal charges, insurance and GST on fees are usually outside this formula.
Illustrative examples
Same loan in every row: ₹40,00,000 at 8.5% a year. Figures are rounded to the nearest rupee from the standard EMI formula. Your lender quote can differ.
15 years
EMI: ₹39,390
Total interest: ₹30,90,125
Total payment: ₹70,90,125
20 years
EMI: ₹34,713
Total interest: ₹43,31,103
Total payment: ₹83,31,103
25 years
EMI: ₹32,209
Total interest: ₹56,62,725
Total payment: ₹96,62,725
A shorter tenure raises the EMI and cuts total interest. A longer tenure lowers the EMI and raises total interest. Confirm the split in the calculator above with the same amount, rate and years.
How to read the result
- Monthly EMI — instalment if the rate stays at the number you entered.
- Total interest — interest over the full term, not one year.
- Total payment — principal plus interest, before most one-time charges.
- Eligibility — a rough ceiling. Many lenders look at total EMIs against net income. It is a policy, not a guarantee.
- Balance transfer — interest difference only. Subtract processing fee, legal cost and any other transfer charge before you call it a saving.
Prepayment and balance transfer
An extra payment toward principal can reduce later interest. Keeping the EMI the same and shortening tenure usually saves more interest than lowering the EMI and keeping the years. On floating-rate home loans to individuals, banks and NBFCs are generally not allowed to levy prepayment charges under RBI directions; fixed-rate or other products can differ. Check your sanction letter.
A balance transfer can help if the new rate is meaningfully lower and you still have many years left. A small rate gap plus high transfer fees may not be worth it. Run both rates here, then ask the new lender for a written cost sheet.
Frequently asked questions
Does this include the down payment?
Enter the loan amount, not the property price. If the house costs ₹50 lakh and you pay ₹10 lakh yourself, the principal to test is ₹40 lakh.
Why is total interest almost as large as the loan?
Interest is charged on the outstanding balance every month for 15–25 years. A long tenure keeps EMI lower and interest higher.
Will the bank approve the eligibility figure?
Not necessarily. Credit score, existing loans, age, income proof and the property can reduce the sanctioned amount.
Floating or fixed — which number should I enter?
Enter the rate in the offer you are comparing. If it is floating, test a higher rate as well. The calculator cannot predict future resets.
Are tax benefits included?
No. Sections and limits for home-loan interest and principal can change. Check the current income-tax rules, or use the Income Tax Calculator only as a separate estimate.
Is a balance transfer always cheaper?
No. Compare the rate gap, remaining tenure, processing fee and other transfer costs. A short remaining tenure often leaves less room to recover those costs.
Should I use the EMI Calculator instead?
Use this page for home-loan modes. For a personal or car loan, the EMI Calculator or Loan Calculator is the closer tool.
