This page is a fixed-deposit calculation guide. It has no interactive FD calculator. The examples use stated assumptions so you can follow the arithmetic and compare it with a bank’s actual deposit terms.
Simple interest
Maturity amount = principal + (principal × annual rate × years), with the percentage written as a decimal. An assumed ₹1,00,000 at ten percent for five years gives ₹1,50,000: ₹1,00,000 + (₹1,00,000 × 0.10 × 5).
Compound interest
For a constant annual nominal rate compounded n times a year, maturity amount = principal × (1 + annual rate ÷ n)n × years. The rate, number of compounding periods and time must use compatible units.
With annual compounding, n = 1. An assumed ₹1,00,000 at ten percent for five years gives ₹1,61,051: ₹1,00,000 × 1.105. These figures are arithmetic examples, not current FD rate quotations.
Match the estimate to the deposit
Check the actual rate, compounding or payout frequency, maturity date and day-count convention. A deposit that pays interest out regularly needs a different cash-flow treatment from one that retains and compounds it. Deductions, fees and premature closure can change what you receive.
The separate lump sum calculator illustrates growth under its own assumptions. It is not a bank-specific FD quotation and does not automatically apply deposit terms or current tax rules.
