Calculate your Fixed Deposit maturity amount and interest earned.
A FD calculator (Fixed Deposit calculator) helps you calculate the maturity amount and interest earned on your fixed deposit investment. By entering the principal amount, interest rate, tenure, and compounding frequency, our online FD calculator instantly shows your returns so you can compare different FD options before investing.
For compound interest FD: Maturity Amount = P × (1 + r/n)^(n×t), where P = Principal, r = Annual interest rate, n = Compounding frequency per year, t = Time in years. For simple interest FD: Interest = P × r × t / 100. Most bank FDs use quarterly compounding, meaning interest compounds 4 times per year.
FD (Fixed Deposit) rates vary significantly between banks and financial institutions, and also by country, since interest rates reflect each country's central bank policy and local market conditions. Smaller finance banks and non-bank institutions often offer higher rates than large traditional banks, though typically with a small increase in risk. Senior citizens commonly get an additional interest rate benefit in many countries. Some countries also offer tax-advantaged fixed deposit options with a lock-in period in exchange for a tax deduction. Always compare rates across multiple banks in your country before opening an FD.
Many countries require banks to withhold a portion of interest earned as tax at source once it crosses a certain annual threshold, with a higher threshold often available for senior citizens. If your total income is below the taxable limit in your country, you may be able to submit a declaration form to your bank to avoid this withholding. This withheld tax is typically a prepayment, not additional tax — it gets adjusted when you file your annual tax return.
FDs offer higher guaranteed returns than savings accounts (typically 6-9% vs 3-4%). They are safer than equity mutual funds but offer lower potential returns. FDs are best for short to medium-term goals (6 months to 5 years) where capital safety is the priority. For long-term goals (7+ years), equity mutual funds typically outperform FDs significantly after accounting for inflation and taxes.
A Fixed Deposit (FD) locks a lump sum of money with a bank for a predetermined term in exchange for a guaranteed, typically fixed interest rate, offering a lower-risk alternative to market-linked investments in exchange for lower potential returns and reduced liquidity, since early withdrawal usually incurs a penalty. The final maturity amount depends on the principal, interest rate, term length, and compounding frequency, with more frequent compounding (quarterly rather than annually, for instance) producing a slightly higher effective return on an identical stated interest rate.
FDs are popular specifically for their predictability and capital safety, particularly appealing to conservative investors or those saving toward a specific near-term goal where protecting the principal matters more than maximizing potential growth, unlike market-linked investments that carry the risk of losing value over the same time period.
Banks typically offer different interest rates for different FD term lengths, and longer terms don't automatically guarantee a proportionally higher rate — comparing the effective annual yield across different term and compounding combinations, rather than just the stated headline rate, gives a more accurate picture of which FD option actually produces the best return for a given investment horizon.
Interest earned on a fixed deposit is generally treated as taxable income in most jurisdictions, and the effective after-tax return can be meaningfully lower than the advertised interest rate once tax is accounted for. Factoring in the applicable tax rate when comparing an FD's return against other investment options gives a more accurate, apples-to-apples comparison of actual take-home returns.
A Fixed Deposit (FD) is a savings instrument offered by banks where you deposit a lump sum for a fixed period at a predetermined interest rate.
Simple interest FDs pay interest only on the principal. Compound interest FDs (more common) pay interest on principal plus previously earned interest.
In most countries, FD interest is fully taxable as income at your applicable tax rate. Many countries also require banks to withhold a portion of interest as tax once it crosses a certain annual threshold, with the exact threshold and rate varying by country.
Yes, most banks allow premature withdrawal of FDs but charge a penalty (usually 0.5% to 1% reduction in interest rate) for early closure.
