Fixed Deposit Calculator - FD Maturity & Interest: Complete Guide
A Fixed Deposit (FD) Calculator helps you calculate the maturity amount and total interest earned on your bank or NBFC fixed deposit. Fixed deposits are the most popular savings instrument in India, offering guaranteed returns with minimal risk. Our free FD calculator supports all compounding frequencies — monthly, quarterly, half-yearly, and annually — giving you accurate maturity values to compare across different banks and tenures.
What is a Fixed Deposit?
A Fixed Deposit (FD) is a financial instrument provided by banks and NBFCs where you deposit a lump sum for a fixed period at a predetermined interest rate. Unlike savings accounts, FDs offer higher interest rates and the rate is locked in for the entire tenure — protecting you from rate cuts during the investment period.
FD interest rates in India (2024) range from 6.5% to 9% depending on the bank, tenure, and your age. Senior citizens typically receive an additional 0.25–0.5% interest above the regular rate.
FD Calculator Formula
For non-cumulative FDs (periodic interest payout), interest is calculated simply:
Interest = P × r × t
For cumulative FDs (compounding), the formula is:
A = P × (1 + r/n)^(n×t)
Where:
- A = Maturity amount
- P = Principal amount
- r = Annual interest rate
- n = Compounding frequency per year (quarterly = 4, monthly = 12)
- t = Investment period in years
Most bank FDs compound quarterly. Our calculator supports all frequencies for accurate comparison.
Tax on FD Interest in India
FD interest income is fully taxable as per your income tax slab in India. Key tax rules:
- TDS: Banks deduct 10% TDS if annual interest exceeds ₹40,000 (₹50,000 for senior citizens)
- No TDS with Form 15G/15H: If your total income is below the taxable limit, submit Form 15G (non-senior) or 15H (senior citizens) to avoid TDS
- Tax impact: At 30% tax slab, a 7% FD effectively yields only ~4.9% post-tax — lower than inflation in many years
For tax-efficient investing, consider tax-saving FDs (5-year lock-in, deduction under 80C) or move funds to debt mutual funds for lower long-term capital gains tax.
Best FD Interest Rates in India 2024
Small finance banks and some private banks offer higher FD rates than public sector banks. Before locking in a large FD, compare rates across:
- Public sector banks: SBI, Bank of Baroda — typically 6.5–7.25%
- Private banks: HDFC, ICICI, Axis — 7–7.5%
- Small Finance Banks: ESAF, Unity, Suryoday — 8.5–9%
- NBFC FDs: Bajaj Finance, Mahindra Finance — 7.75–8.35%
Remember: NBFC FDs are not covered by DICGC insurance (₹5 lakh coverage only for bank FDs). Always check NBFC credit ratings before investing.
