FD Calculator 2026 – Calculate Fixed Deposit Interest & Maturity
Calculate the exact maturity value, total interest earned, and quarterly compounding growth for your bank Fixed Deposit (FD). Test different deposit amounts, tenures (in years or days), and compounding frequencies under current Indian bank interest rate slabs.
If you are placing a single lump sum into a bank FD, this calculator solves for your final maturity proceeds after accounting for RBI standard quarterly compounding. For multi-deposit liquidity scheduling, use our linked FD Ladder, or check bank safety exposure with our DICGC calculator.

Planning Beyond a Single Fixed Deposit?
A single FD locks your entire capital in one maturity date. Depending on your financial objective, your next logical planning step may involve staggering maturities or dividing deposits across multiple banks.
Instead of locking 100% of your money in one 5-year FD, spread it across 1, 2, 3, 4, and 5-year tenures to unlock 20% capital every year.

Mathematical mechanics of quarterly compounding mandated under RBI regulations
In India, bank Fixed Deposits do not calculate simple annual interest for tenures exceeding 6 months. Under Reserve Bank of India guidelines, all commercial banks compound interest on a quarterly basis (every 3 calendar months).
- A: Total maturity amount received at the end of the tenure.
- P: Principal deposit amount (initial lump sum invested).
- r: Annual interest rate percentage (e.g. 7.25 for 7.25% p.a.).
- n: Investment tenure expressed in years (or fraction of years).
Because interest earned during each quarter is added to the principal to earn further interest in the subsequent quarter, the effective annual yield of an FD is always higher than its quoted nominal rate.

Real Returns: Factoring in Inflation & Income Tax
Why nominal FD returns differ from your real post-tax purchasing power.
Fixed Deposit interest is 100% taxable under ‘Income from Other Sources’ according to your income tax slab. If you fall in the 30% tax bracket, a nominal 7.20% FD rate yields an effective post-tax return of only ~5.04% p.a.
Banks deduct 10% TDS under Section 194A if total interest exceeds ₹40,000 (₹50,000 for seniors). Eligible depositors can submit Form 15G/15H to prevent TDS.
A fixed return is nominal. If consumer price inflation averages 6.00% and your post-tax FD return is 5.04%, your capital experiences negative real growth over long tenures.
Frequently Asked Questions (FD Calculations)
Authoritative answers regarding bank FD calculations, compounding, and taxation in India.
How is FD interest calculated in India?
Under Reserve Bank of India (RBI) guidelines, Indian commercial banks compound fixed deposit interest on a quarterly basis (every 3 months) using the compound interest formula: A = P × (1 + r / 400)^(4n), where A is maturity value, P is principal, r is annual interest rate %, and n is tenure in years.
What is the difference between Cumulative and Non-Cumulative FDs?
In a Cumulative FD (reinvestment plan), interest is compounded quarterly and paid out together with principal upon maturity, maximizing total growth. In a Non-Cumulative FD, interest is paid out monthly, quarterly, or half-yearly to your bank account for cash flow needs.
How does tenure affect FD interest rates?
Different bank tenures fall into different rate slabs. Generally, 1-year to 3-year or 5-year tenures offer peak interest rates (7.00%–7.75% p.a.). Short tenures (7–90 days) offer lower rates (3.00%–4.50% p.a.).
How is Fixed Deposit interest taxed in India?
FD interest is categorized under 'Income from Other Sources' and taxed at your applicable personal income tax slab rate. Banks deduct 10% TDS under Section 194A if total FD interest across all branches of a bank exceeds ₹40,000 in a financial year for regular individuals (₹50,000 for senior citizens aged 60+).
Do senior citizens get higher FD interest rates?
Yes. Most Indian banks offer an additional 0.50% p.a. (and up to 0.75%–0.80% under special super senior schemes) to depositors aged 60 and above. Senior citizens can also claim up to ₹50,000 interest deduction under Section 80TTB.
What is the premature withdrawal penalty on a bank FD?
If you break a fixed deposit before its contracted maturity date, banks typically levy a premature penalty of 0.50% to 1.00% on the effective interest rate for the actual period the deposit remained with the bank.
Is my Fixed Deposit principal safe with banks in India?
Fixed deposits in all Indian scheduled commercial banks (public, private, and small finance banks) are protected by the Deposit Insurance and Credit Guarantee Corporation (DICGC), a wholly-owned RBI subsidiary, up to ₹5,00,000 (₹5 Lakhs) covering principal plus interest per depositor per bank.
When should I choose an FD Ladder instead of a single Fixed Deposit?
If you are investing a large lump sum (e.g. ₹5 Lakhs to ₹50 Lakhs) and want regular liquidity without locking 100% of your capital or paying premature penalty fees, an FD ladder with staggered maturities is superior to a single fixed deposit.
Bank Fixed Deposit rules, compounding frequencies, and deposit insurance limits are governed by the Reserve Bank of India (RBI) and Deposit Insurance and Credit Guarantee Corporation (DICGC). Taxation guidelines reflect Section 194A, Section 80C, and Section 80TTB of the Income Tax Act, 1961. This calculator provides educational mathematical projections.
