FD Calculator is now live on Tools.Town — a tool for calculating Fixed Deposit maturity amounts and interest earned, supporting all standard compounding frequencies, a senior citizen rate toggle, and optional TDS deduction.

What Does It Do?

Maturity Amount

Calculate the total value of your FD at maturity — principal plus total interest earned.

All Frequencies

Monthly, quarterly, half-yearly, and annual compounding — matches the terms of any bank or NBFC FD.

TDS & Comparison

See gross and post-TDS amounts side by side. Compare simple vs compound interest in one view.

Senior citizen FD rates are typically 0.25–0.50% higher. Toggle the senior citizen option to see the impact on your maturity amount.

Why We Built It

Fixed Deposits remain one of the most popular savings instruments in India. But calculating the exact maturity amount — especially with quarterly compounding and TDS — is not straightforward mental math. FD Calculator makes the math transparent, so you can compare offers from different banks and make informed decisions.

Frequently Asked Questions

What compounding frequencies are supported?
Monthly, quarterly, half-yearly, and annual compounding — matching the options offered by most Indian banks and NBFCs.
Does it account for TDS deduction?
Yes. You can toggle TDS (Tax Deducted at Source) at 10% for resident Indians and see post-TDS maturity amount alongside the gross amount.
What's the difference between simple and compound interest for FDs?
Most bank FDs use compound interest. Senior citizen FDs often offer a higher rate. The calculator defaults to compound interest but can show simple interest for comparison.
