Loan Calculator

Calculate total loan cost, EMI and interest payable.

Checking figures on paper takes time and invites small mistakes. Loan Calculator takes total cost, down payment, annual interest rate, and loan term and gives an instant result you can recalculate with different values.

Planning a loan: amount, rate, tenure and total cost

Any loan, whether for a home, car, education or personal needs, is defined by three numbers: the amount borrowed, the annual interest rate and the repayment period. This calculator turns them into a monthly instalment, the total interest and the total amount you will repay. Seeing the total cost before you sign is the single most useful step in comparing offers.

How the instalment is calculated

The monthly instalment follows the reducing-balance method: interest each month is charged only on the amount still owed. With principal P, monthly rate r and n months, the payment is P × r × (1 + r)n ÷ ((1 + r)n − 1). Total interest is the instalment multiplied by n, minus P.

Example: comparing two offers

Take ₹5,00,000 for 5 years. At 10.5% the instalment is about ₹10,747 and total interest about ₹1.45 lakh. At 12% the instalment is about ₹11,122 and total interest about ₹1.67 lakh. The ₹375 monthly gap looks small, yet the extra cost over the loan is more than ₹22,000.

What to compare besides the rate

  • Processing fee, usually a percentage of the loan, charged upfront.
  • Prepayment and foreclosure charges, especially on fixed-rate loans.
  • Whether the rate is fixed, floating or a teaser that resets.
  • Mandatory insurance or bundled products added to the loan amount.

Choosing the tenure

A long tenure lowers the instalment but raises total interest. A short tenure saves money but strains the monthly budget. A practical approach is to pick the shortest tenure where the instalment stays below about 30 to 40 per cent of your monthly take-home pay, leaving room for emergencies.

Fixed versus reducing balance (flat) rates

Some lenders quote a flat rate, where interest is charged on the original amount for the whole period. A flat 8% is much costlier than 8% on a reducing balance, often equal to about 14 to 15% reducing. Always ask for the effective annual rate and the full repayment schedule so that offers can be compared on the same basis.

Protecting your credit score

Pay on time, avoid taking several loans at once, and keep credit card use under about 30 per cent of the limit. A good score can help you negotiate a lower rate. Check your credit report once a year for errors and raise a dispute with the bureau if you find one. The Reserve Bank of India's consumer pages explain borrower rights, including what lenders must disclose before you accept a loan.
