What is a Fixed Deposit (FD) Calculator?

A Fixed Deposit (FD) Calculator is a free online tool that helps you estimate the maturity amount and total interest earned on a fixed deposit investment. FDs are one of the most popular and trusted savings instruments in India, offering guaranteed returns, capital protection, and DICGC insurance up to INR 5 lakh per depositor per bank.

Unlike market-linked investments, FD returns are completely predictable — you know exactly what you will receive at maturity before you invest. This calculator lets you compare different FD scenarios (varying tenure, rates, and compounding frequencies) to maximise your returns.

This calculator supports all types of FDs — short-term (7 days to 1 year), medium-term (1–3 years), long-term (3–10 years), tax-saving FDs (5-year lock-in), and cumulative vs non-cumulative FDs. It also accounts for the senior citizen interest rate premium offered by banks.

FD Interest Calculation Formula

FD interest uses the compound interest formula:

A = P × (1 + r/n)^(n×t)

Where: A = Maturity amount, P = Principal invested, r = Annual interest rate (as decimal), n = Compounding frequency per year (4 for quarterly), t = Tenure in years. For INR 1,00,000 at 7.1% p.a. compounded quarterly for 5 years: A = 1,00,000 × (1 + 0.071/4)^(4×5) ≈ INR 1,42,302. Total interest earned ≈ INR 42,302.

FD Interest Rates in India (2025)

Major Public Sector Banks

SBI, PNB, Bank of Baroda, Union Bank typically offer 4.5%–7.0% p.a. for general public and 5.0%–7.5% for senior citizens. Rates vary by tenure slab. Special rates apply during promotional periods.

Major Private Sector Banks

HDFC, ICICI, Axis, Kotak typically offer 5.0%–7.5% p.a. for regular customers and 5.5%–8.0% for senior citizens. Private banks often offer special higher rates for specific tenures (e.g., 15 months, 33 months, 444 days).

Small Finance Banks

AU, Equitas, Jana, Suryoday SFBs typically offer 7.0%–9.0% p.a. for general public and up to 9.5% for senior citizens. Higher rates come with slightly higher risk — ensure DICGC coverage applies.

Post Office Time Deposit

Post Office FD (1–5 years) offers sovereign-guaranteed rates: 6.9% (1-year), 7.0% (2-year), 7.1% (3-year), 7.5% (5-year). All rates are quarterly compounded and carry government guarantee.

Cumulative vs Non-Cumulative FD — Which Should You Choose?

The choice between cumulative and non-cumulative FDs depends on your need for regular income versus corpus growth:

  • Cumulative FD: Interest is compounded and paid at maturity along with the principal. Ideal for long-term goals where you do not need regular income. Earns more due to compounding. Example: INR 5 lakh at 7% for 5 years gives a maturity amount of ~INR 7.04 lakh.
  • Non-Cumulative FD: Interest is paid periodically (monthly, quarterly, semi-annually, or annually). Suitable for retirees and those who need regular income. The principal is returned at maturity. Monthly payouts are calculated at a slightly lower effective rate due to frequency.

For wealth accumulation and long-term savings, cumulative FDs are superior. For regular income needs (such as post-retirement), non-cumulative FDs are the practical choice — especially when combined with a Senior Citizen Savings Scheme (SCSS) or Post Office Monthly Income Scheme (MIS).

Tax Implications on FD Interest

FD interest is fully taxable as income from other sources under the Income Tax Act, regardless of whether you withdraw the interest or allow it to accumulate. Key tax points:

  • TDS at 10% is deducted at source if total FD interest from a bank exceeds INR 40,000 per year (INR 50,000 for senior citizens).
  • If your PAN is not linked to the FD, TDS is deducted at 20%.
  • Submit Form 15G (below 60 years) or Form 15H (60+ years) at the start of each financial year to avoid TDS if your total income is below the taxable threshold.
  • A 5-year Tax-Saving FD qualifies for 80C deduction (old regime only) up to INR 1.5 lakh per year. However, the interest earned is fully taxable.

Tips to Maximise FD Returns

  • Compare rates across small finance banks and NBFCs — they often offer 1%–2% higher rates than large banks, with the same DICGC protection up to INR 5 lakh.
  • For deposits above INR 5 lakh, split across multiple banks to ensure full DICGC coverage.
  • Opt for quarterly compounding over annual compounding for the same stated rate — quarterly compounding yields a slightly higher effective return.
  • Ladder your FDs across different tenures (e.g., 1, 2, 3, and 5 years) so a portion matures regularly — this provides liquidity and reduces reinvestment risk when rates change.
  • Senior citizens should specifically ask about the senior citizen FD rate card — rates vary by bank and can be 0.25%–0.75% higher than the general rate.
Disclaimer: FD rates shown are indicative and sourced from publicly available bank rate cards. Actual rates offered by your bank may differ based on the amount, specific tenure chosen, and prevailing promotions. Interest calculations are based on standard quarterly compounding. Verify the exact rate with your bank before investing.

Frequently Asked Questions (FAQs)

An FD is a financial instrument where you deposit a lump sum for a fixed period at a predetermined interest rate. At maturity you receive the principal plus compounded interest. FDs earn more than savings accounts and are covered by DICGC up to INR 5 lakh.

Most banks compound FD interest quarterly: A = P(1 + r/n)^(nt), where A is the maturity amount, P is the principal, r is the annual rate as a decimal, n is compounding frequency (4 for quarterly), and t is tenure in years.

Major bank FD rates range from 4.5% to 7.5% p.a. for the general public; small finance banks offer up to 8.5%–9%. Senior citizens get an additional 0.25%–0.50%.

Senior citizens (60+) receive 0.25%–0.50% p.a. extra over regular rates at most banks, and some offer up to 0.75% extra. This applies to their own FDs; joint accounts where the senior is secondary may not qualify.

Yes. FD interest is taxable as per your income slab. TDS at 10% is deducted if annual interest exceeds INR 40,000 (INR 50,000 for seniors). Submit Form 15G/15H to avoid TDS if your total income is below the taxable limit.

Tax-saving FDs have a 5-year lock-in and qualify for 80C deduction up to INR 1.5 lakh per year. The interest is taxable and premature withdrawal is not permitted.

Cumulative FDs compound interest and pay everything at maturity. Non-cumulative FDs pay interest periodically (monthly, quarterly, annually) as a regular income stream. Cumulative FDs earn more due to compounding.

Yes. Most banks lend up to 80%–90% of the FD value. The loan rate is typically 1%–2% above the FD rate. This avoids premature withdrawal penalties while keeping the FD earning interest.

Premature withdrawal typically reduces the effective rate by 0.5%–1% from what was applicable for the actual holding period. Some banks have a minimum holding period (e.g., 7 days). Tax-saving FDs cannot be withdrawn prematurely.

Yes. Scheduled commercial bank deposits including FDs are insured by DICGC up to INR 5 lakh per depositor per bank (principal + interest combined). Amounts above INR 5 lakh are not insured.
