Frequently asked questions
Most banks compound FD interest quarterly. The maturity value is principal × (1 + r/n)^(n×t), where n is the compounding frequency. This calculator defaults to quarterly compounding.
Yes. Interest is added to your income and taxed at your slab rate. Banks deduct TDS if interest exceeds the annual threshold, though you can submit Form 15G/15H if eligible.
Cumulative FDs reinvest interest until maturity (shown here), maximising compounding. Non-cumulative FDs pay interest out periodically, suiting those who need regular income.
Yes, but premature withdrawal usually attracts a penalty and a lower interest rate. Always check your bank's terms before locking in a long tenure.
The rate on the brochure isn't quite the rate you earn
A bank might advertise 7% on a fixed deposit, but lock in ₹1,00,000 for 5 years at that rate with quarterly compounding — the default most Indian banks actually use — and you get back ₹1,41,478, not the flat ₹1,35,000 a simple 7%-a-year mental shortcut would suggest. The extra ₹6,478 comes from interest being added to your balance four times a year instead of once, so each quarter's interest starts earning its own interest a little sooner.
The formula behind the number
FD maturity follows the standard compound interest formula, A = P × (1 + r/n)ⁿᵗ, where n is however many times a year interest compounds — quarterly by default here, though some banks offer half-yearly, annual or monthly options. Switch the compounding frequency on this calculator and watch the maturity value move: more frequent compounding always earns slightly more at an identical stated rate, though the effect is smaller than most people expect.
What you're actually trading for that guarantee
An FD's entire value proposition is certainty — the rate is locked the day you deposit, and nothing that happens in the stock market between now and maturity changes what you get back. That makes it well suited to money you genuinely cannot afford to see shrink: an emergency fund, or a goal with a fixed date within the next few years. The trade-off shows up at tax time: FD interest is added to your taxable income and taxed at your full slab rate, with banks deducting TDS once interest crosses the annual threshold (Form 15G/15H can exempt you from that if your total income falls below the taxable limit). In a high-inflation year, the real, inflation-adjusted return on an FD can shrink close to zero or turn negative even while the account statement shows a gain. Worth comparing before you lock in a rate: a cumulative FD (modelled here) reinvests interest until maturity, while a non-cumulative FD pays it out periodically — better suited to someone who needs the income now rather than a lump sum later.
