What is a FD Calculator?
A fixed deposit locks in a lump sum with a bank or NBFC for a chosen tenure at a fixed interest rate, agreed upfront regardless of where market rates move afterward. Most Indian banks compound FD interest quarterly, though some offer monthly or annual compounding — the frequency alone can shift the effective return by a noticeable amount over longer tenures.
Enter your deposit amount, the rate your bank is offering, the tenure, and the compounding frequency to see the maturity value.
How the maturity value is calculated
k is the number of times interest compounds per year — 4 for quarterly (the most common convention for Indian bank FDs), 12 for monthly, or 1 for annual. More frequent compounding gives a slightly higher maturity value for the same stated rate.
Worked example: what compounding frequency is actually worth
₹1,00,000 at 7% for 5 years matures to roughly ₹1,40,255 with annual compounding, ₹1,41,478 with quarterly compounding (the standard for most Indian bank FDs), and ₹1,41,763 with monthly compounding. The difference between annual and quarterly is about ₹1,223 over 5 years; between quarterly and monthly, only about ₹285 more. Compounding frequency matters, but far less than the headline rate itself — a 0.25% higher rate from a different bank will usually outweigh any difference in compounding frequency.
Splitting one FD into several (laddering)
Rather than locking one lumpsum into a single FD, some savers split it across several FDs with staggered maturity dates — a practice called laddering. The benefit is liquidity: instead of needing to break one large FD (and losing some interest to a premature-withdrawal penalty) for an unplanned expense, only the smallest, nearest-maturing piece needs breaking. This calculator projects a single deposit; run it multiple times with a smaller principal and different tenures to model a ladder.
Frequently asked questions
Is FD interest taxable?
Yes — fully taxable at your income slab rate, added to your total income each year it accrues (not just at maturity), and banks deduct TDS if the interest crosses the applicable threshold in a year.
What’s the difference between cumulative and non-cumulative FDs?
This calculator assumes a cumulative FD, where interest is reinvested and paid out at maturity. A non-cumulative FD instead pays interest out periodically (monthly/quarterly), so the balance itself doesn’t compound.
Do senior citizens get a better rate?
Most banks offer roughly 0.25–0.75 percentage points extra for senior citizens — use that higher rate directly in the calculator if it applies to you.
What happens if I withdraw an FD before maturity?
Most banks allow premature withdrawal but apply a penalty, typically 0.5–1% lower interest than the rate that would otherwise apply for the period actually held — check your specific bank’s premature withdrawal terms before locking in.
Is FD interest safer than a debt mutual fund?
Bank FDs up to ₹5 lakh per bank are covered by DICGC deposit insurance, giving them a specific government-backed safety net that debt mutual funds don’t have — though debt funds can offer better post-tax returns in some cases depending on your tax slab and holding period.
Can I get a loan against my FD?
Yes — most banks offer a loan or overdraft against an FD, typically up to 90–95% of its value, at a rate slightly above the FD’s own rate, without breaking the deposit.
How is FD different from NSC or SCSS?
An FD’s rate is set by the individual bank and can vary between banks and change over time for new deposits. NSC and SCSS rates are set by the government and apply uniformly wherever you invest — the trade-off is a bank FD gives you rate-shopping flexibility, while government schemes give a uniform, centrally-set rate.
