FD Calculator: Project Fixed Deposit Maturity Accurately

A fixed deposit is the anchor of most Indian savings plans because the return is guaranteed and compounding works quietly in your favour. Our FD calculator uses the industry formula A = P x (1 + r/4)^(4 x n), where interest compounds every quarter, exactly like banks do. Enter your deposit amount, annual rate and duration to see maturity value, total interest and effective yield instantly.

Why quarterly compounding matters

• Higher than simple interest: each quarter interest is added to principal, so the next quarter earns on a bigger base.
• Rate comparison: a 7.5% FD compounded quarterly beats 7.5% paid annually.
• Tenure effect: extending from 1 to 5 years multiplies the compounding cycles from 4 to 20.

How to use FDs smartly

Ladder deposits across 1, 3 and 5 year tenures so some money frees up regularly while long-term deposits earn more. Senior citizens typically get 0.25-0.50% extra, which you can model by raising the rate input. Remember that interest above Rs 40,000 per year (Rs 50,000 for seniors) attracts TDS, so your in-hand return may be slightly lower than the gross maturity shown here.

Example

Rs 2,00,000 at 7.2% for 3 years grows to about Rs 2,47,500 with quarterly compounding, earning roughly Rs 47,500 in interest. Change any input and the projection updates immediately, helping you compare bank offers side by side.
