Calculator Interest

Calculate simple and compound interest on loans and investments

Principal Amount (₹) *
question-icon The initial amount invested or borrowed. This is the base amount on which interest is calculated. For investments, this is your starting capital. For loans, this is the amount borrowed.
Interest Rate p.a (%)*
question-icon The annual interest rate applied to your principal (in percentage). Simple interest calculates only on principal, while compound interest calculates on principal plus previously earned interest. Rates vary: savings accounts (3-6%), FDs (5-8%), loans (8-15%).
Time Unit*
question-icon Select whether your time period is measured in years, months, or days. The calculator will automatically convert to the appropriate unit for accurate interest calculation. Most calculations use years as the standard unit.
Time Period*
Interest Type*
question-icon Simple interest is calculated only on the principal amount. Compound interest is calculated on principal plus previously earned interest, resulting in exponential growth. Compound interest yields significantly higher returns over long periods.
Compounding Frequency*
question-icon How often interest is calculated and added to your principal. More frequent compounding (monthly/daily) yields higher returns than annual compounding. Most savings accounts compound monthly, while FDs typically compound quarterly.
