FD Calculator

What This FD Calculator Does

A Fixed Deposit (FD) is a lumpsum deposited with a bank for a fixed tenure at a fixed interest rate. This calculator estimates the maturity value of an FD, assuming quarterly compounding - the convention most Indian banks use for standard FDs.

The Formula

FDs use the standard compound interest formula: A = P × (1 + r/4)^(4×t), where P is your deposit amount, r is the annual interest rate, and t is the tenure in years. The 4 reflects quarterly compounding - interest is calculated and added to the principal every three months rather than just once a year.

How to Use It

Enter your deposit amount, the interest rate your bank is offering, and the tenure in years. The calculator shows your original deposit, the interest earned over the tenure, and the total maturity value you would receive.

What This Calculator Doesn't Account For

Actual FD returns can differ slightly from this projection: banks sometimes use day-count conventions that don't divide perfectly into quarters, senior citizens often get a rate premium, and interest earned is taxable at your income slab rate (with TDS deducted if it crosses the threshold in a year), which isn't reflected here. Treat this as a close estimate for comparison purposes, and confirm the exact figure with your bank before committing.

Who This Is For

Anyone comparing FD offers from different banks or tenures, or wanting to see how an FD's guaranteed, fixed return stacks up against a market-linked mutual fund SIP or lumpsum - the Mutual Fund vs FD Comparator is built for exactly that side-by-side comparison.

Quick Example

₹3,00,000 deposited in an FD at 7% for 5 years, compounded quarterly, matures to approximately ₹4,24,433 - about ₹1,24,433 in interest earned on top of the original deposit, before tax.
