How a home loan EMI is calculated
Home loan EMIs use the standard reducing-balance formula:
where P is the loan amount, r is the monthly interest rate (annual rate ÷ 12 ÷ 100), and n is the number of monthly instalments (years × 12).
Fixed vs floating rate
Most Indian home loans today are offered on a floating rate, linked to an external benchmark such as the repo rate. When the benchmark moves, your lender typically keeps the EMI the same and adjusts the tenure — or, in some cases, adjusts the EMI itself. A smaller number of loans offer a fixed rate, usually only for an initial period, after which they revert to floating. This calculator shows a single point-in-time estimate assuming your current rate holds for the full tenure, which is a simplification.
Tax benefits — check current rules
Home loan principal repayment and interest may be eligible for deductions under applicable sections of the Income Tax Act, subject to conditions that depend on the property, whether it's self-occupied, and the tax regime you choose. Limits and eligibility change with the law, so this calculator does not estimate tax savings — confirm current rules with a tax advisor or the Income Tax Department before relying on any figure.
