What 7% works out to once quarterly compounding is applied.
An FD calculator works out the maturity amount and interest on a fixed deposit from the deposit amount, interest rate, tenure, and compounding frequency, using the compound interest formula. Actual maturity amounts can vary with your bank's product terms and calculation conventions.

Smart Insights
Generated from the numbers you entered — no guesswork.
- Your ₹1,00,000 deposit would grow to approximately ₹1,07,186 over 1 year at the entered rate and quarterly compounding.
- Interest of ₹7,186 contributes approximately 6.7% of the maturity amount.
- That is a calculated growth of 7.2% on the amount deposited.
- Compounding quarterly lifts the effective annual yield to 7.19% from the headline 7%.
- Figures are calculated from the values you enter. FD interest is taxable at your income slab rate, and banks may deduct TDS, so the amount credited can be lower.
How does the FD Calculator work?
Each step the calculator runs, in plain language.
- 1
What is a fixed deposit?
A fixed deposit is a bank or NBFC product where you place a lump sum for a fixed tenure at a fixed interest rate agreed upfront. The rate does not change during the term, so the maturity amount is known the day you open it. Deposits with scheduled banks are insured up to ₹5 lakh per depositor per bank under DICGC cover.
- 2
How does an FD work?
You choose an amount and a tenure, and the bank locks the rate applicable to that tenure. In a cumulative FD the interest is added to your balance at each compounding date and paid together with the principal at maturity. In a non-cumulative FD the interest is paid out monthly or quarterly instead, so the balance stays at the original deposit. This calculator models the cumulative option.
- 3
How FD interest is calculated
Banks use compound interest: A = P × (1 + r ÷ n)^(n × t). The annual rate is divided by the number of compounding periods per year to get the rate per period, and the balance is multiplied by that growth factor once per period for the whole tenure. Interest earned is the maturity amount minus the principal.
- 4
What is compounding frequency?
Compounding frequency is how often earned interest is added to your balance — monthly (12), quarterly (4), half-yearly (2), or yearly (1). Most Indian banks compound FDs quarterly. More frequent compounding means interest starts earning interest sooner, which raises the effective annual yield slightly above the quoted rate.
- 5
Maturity amount vs interest earned
The maturity amount is the full sum credited at the end: your principal plus all the interest. Interest earned is only the growth portion. Comparing the two shows what share of your maturity value the bank added — and it is the interest portion, not the maturity amount, that is taxable at your slab rate.
FD Calculator formula
The exact maths behind every number on this page.
A = P × (1 + r ÷ n)^(n × t)
- A
- Maturity amount — what the bank pays at the end of the tenure
- P
- Principal, the amount you deposit
- r
- Annual interest rate as a decimal (7% → 0.07)
- n
- Number of compounding periods per year (quarterly = 4)
- t
- Tenure in years (tenure in months ÷ 12)
Compounding frequency decides how often earned interest is added back to the balance so it starts earning interest itself. A higher n means interest is credited more often, so the same headline rate produces a slightly larger maturity amount — this is why the effective annual yield is a little above the quoted rate. Total interest earned is simply A − P. The calculation assumes a cumulative deposit held to maturity, with no TDS, tax, or premature-withdrawal penalty applied.
FD Calculator calculation example
₹1,00,000 deposited for 1 year at 7% a year, compounded quarterly.
- 1Principal (P)₹1,00,000
- 2Rate (r)7 ÷ 100 = 0.07
- 3Compounding (n)4 periods per year
- 4Tenure (t)12 ÷ 12 = 1 year
- 5Maturity (A)1,00,000 × (1 + 0.07 ÷ 4)^4 = ₹1,07,186 (approx.)
- 6Interest earned (A − P)₹7,186 (approx.)
The deposit matures at about ₹1,07,186, so ₹7,186 is interest — an effective yield of roughly 7.19% because quarterly compounding credits interest four times in the year.
Important assumptions
What this calculation includes, and what it leaves out.
- The deposit is held to maturity, and interest is reinvested at the same rate rather than paid out monthly or quarterly.
- The rate you enter applies for the entire tenure; a bank's actual senior-citizen or special-tenure rate may differ.
- Interest is compounded at the frequency you select. Banks may use different day-count or rounding conventions, so a bank quote can differ slightly.
- Figures are before tax. Interest is taxable at your slab rate and TDS may apply.
Benefits
Why people use this calculator before signing a loan.
Predictable, known-in-advance returns
The rate is fixed at booking, so the maturity amount can be calculated exactly instead of estimated.
Flexible tenures
Tenures run from a few months to ten years, so you can align the maturity with a specific goal.
Deposit insurance
Bank deposits are covered up to ₹5 lakh per depositor per bank, which makes FDs a low-risk place for short-term money.
Limitations to keep in mind
Interest is fully taxable at your slab rate, returns may trail inflation over long periods, and breaking the FD early usually costs a 0.5–1% penalty.
Financial tips
Practical guidance to act on your result.
- Split large deposits into several FDs so you can break just one if you need cash early.
- Senior citizens usually get 0.25–0.50% extra on the same tenure — check the senior rate card.
- Submit Form 15G/15H if your total income falls below the taxable limit to avoid TDS.
- Compare the effective yield, not the headline rate — compounding frequency differs by bank.
