Interest & Returns Calculators
Calculate annual percentage yield, daily compound interest and fixed deposit and other interest & returns calculations.
Deposit calculators for money you park with a bank: fixed deposits, recurring deposits, and plain compound or simple interest. The quoted rate on a deposit is only half the story — how often interest compounds changes what you actually receive.
Which Interest & Returns calculator do you need?
- What will my fixed deposit be worth at maturity?Fixed Deposit CalculatorMaturity value with quarterly compounding, the usual convention for Indian bank FDs.
- What will a monthly recurring deposit add up to?Recurring Deposit CalculatorMaturity of monthly deposits with quarterly compounding.
- What is the real annual yield of a quoted rate?Annual Percentage Yield CalculatorConverts a nominal rate and compounding frequency into the effective annual yield.
- How does monthly compounding compare with daily?Monthly Compound Interest CalculatorGrowth with monthly compounding; the daily-compounding calculator shows the other case.
- Interest with no compounding at allSimple Interest CalculatorSimple interest on a principal over a period.

Two deposits at the same rate can pay different amounts
An FD at 7% compounded quarterly yields a little over 7.18% a year, while one that pays interest out every quarter yields exactly 7% on your principal because nothing is reinvested. The APY calculator turns any quoted rate and compounding frequency into the effective figure, so different offers can be compared fairly.
Limitations
- Bank rates and compounding conventions vary; enter your bank's actual terms.
- TDS on interest and premature-withdrawal penalties are not deducted.

FD vs RD: Which Earns More Interest for the Same Money?
For the same total amount invested at the same rate over the same tenure, a Fixed Deposit (FD) earns noticeably more interest than a Recurring Deposit (RD), because an FD's full principal earns interest from day one, while an RD's money arrives gradually and each monthly installment earns interest only from the month it's deposited.
Read guideHow APY Reveals the True Return on a Deposit
APY (Annual Percentage Yield) accounts for how often interest compounds — a nominal 8% rate compounded monthly actually pays out 8.3% over a year, and compounding more often pushes that figure up even further.
Read guideHow Compounding Frequency Changes Your Interest Earned
The same principal, rate, and duration earn slightly more interest when compounded daily than when compounded monthly — because interest gets added back into the balance more often, starting to earn its own interest sooner.
Read guideHow Fixed Deposit (FD) Interest Is Actually Calculated
Indian bank FDs conventionally compound quarterly, not annually or as simple interest — the formula is maturityAmount = Principal × (1 + rate/4)^(tenure in quarters) — which earns more than plain simple interest at the same quoted annual rate, and the gap widens the longer the tenure runs.
Read guideHow Recurring Deposit (RD) Maturity Is Calculated
RD maturity is more complex than FD maturity because each monthly installment starts earning interest at a different point in time — the first deposit compounds for almost the whole tenure while the last deposit barely compounds at all — so the formula has to account for every installment's individual compounding period, not just one lump sum.
