- Calculate periodic interest payouts without reinvestment for non-cumulative mode.
- Split the result into principal, interest, maturity value, and total payout.
Core assumptions
- Interest rate stays fixed through the FD tenure.

About FD Calculator
Guide1What is a Fixed Deposit (FD)?
A Fixed Deposit is one of the safest investment instruments in India where you deposit a lump sum amount with a bank or NBFC for a fixed tenure at a predetermined interest rate. The returns are guaranteed and not affected by market fluctuations.
FDs are insured up to ₹5 lakh per depositor per bank under DICGC (Deposit Insurance and Credit Guarantee Corporation), making them one of the most secure investment options available.
2FD Interest Calculation
FD interest can be calculated differently based on payout type:
Cumulative FD: A = P × (1 + r/n)^(n×t)
Non-cumulative FD: I = P × r × t, with interest paid at the selected frequency and principal returned at maturity.
- A = Maturity amount
- I = Total interest paid
- P = Principal deposit amount
- r = Annual interest rate (in decimal)
- n = Compounding or payout frequency
- t = Tenure in years
Most Indian banks compound cumulative FD interest quarterly, while non-cumulative FDs are often chosen for regular income.

5Tax Implications on FD
Interest earned on fixed deposits is fully taxable as per your income tax slab. Key tax rules include:
- TDS: Banks deduct TDS at 10% if annual interest exceeds ₹40,000 (₹50,000 for senior citizens)
- Form 15G/15H: Submit these forms if your total income is below the taxable limit to avoid TDS
- Tax-Saving FD: Only the principal (up to ₹1.5 lakh) gets Section 80C deduction; the interest is still taxable
