6-8% depending on bank and tenure.

Tax Regime for Final Tax Liability

Used to estimate the extra income tax the FD interest adds on top of your other income. TDS is always 10% above the Section 194A threshold, regardless of regime.

Your Other Annual Taxable Income (₹)

Taxable income from salary, business etc. AFTER deductions, excluding this FD's interest. The tax shown is the extra tax the interest causes at your slab, so a low figure means little or no tax.

How this estimate was calculated

Interest compounded quarterly at 7.20% over 5 year(s), using M = P(1 + r/n)^(nt).

Financial Disclaimer: This calculator provides an estimate only, based on the principal, interest rate, tenure, and compounding options you enter. Actual FD rates and payout terms vary by bank and change over time, and TDS/tax figures shown are approximations, not a final tax computation. Consult a qualified financial adviser or chartered accountant before making investment decisions. Full disclaimer.

Formula & methodology

Formula used

Maturity Value = P × (1 + r/n)^(n×t); TDS = 10% × Interest in each year where that year’s interest > Threshold, otherwise 0

Maturity value uses the standard compound-interest formula: principal (P) grows at the annual rate (r), compounded n times per year (quarterly, monthly, or yearly, as selected) over t years. Senior citizens get a +0.50 percentage point rate bump applied before compounding, matching the typical bank practice. TDS under Section 194A is calculated separately, year by year: the threshold (₹50,000, or ₹1,00,000 for senior citizens) is a trigger tested on each year's interest, and in any year it is crossed the bank deducts 10% of that whole year's interest, not just the excess — this is a withholding, not the final tax. On a cumulative FD the interest grows every year, so later years can cross the threshold when earlier ones do not. The estimated final income-tax is the extra tax each year's interest adds on top of the other annual taxable income you enter, under the selected regime's slabs, Section 87A rebate and cess.

Limitations

The senior citizen rate bump (+0.50 percentage points) is a typical industry approximation — actual bank premiums for senior citizens range from about 0.25% to 0.75% and vary by bank and tenure.
The final income-tax estimate assumes the same other taxable income every year of the deposit, and counts years from the deposit date; real financial years run April–March, so the split of interest between years (and hence TDS) can differ slightly.
Does not model TDS certificate/Form 15G/15H exemptions, or premature-withdrawal penalty rates, which vary by bank.

This page is educational. It applies published rates and thresholds to the figures you enter and shows the arithmetic behind the result. It is an estimate, not a tax determination: your actual liability depends on circumstances this calculator does not collect, and only the relevant tax authority — or an accountant who can see your full position — can confirm what you owe.

Help & FAQs

Frequently Asked Questions

Clear answers to common questions to help you use this calculator confidently.

How is FD maturity value calculated?

Tap to view the answer

Fixed Deposit interest is calculated using the compound interest formula A = P(1 + r/n)^(nt), where P is the principal, r is the annual rate, n is the compounding frequency, and t is the tenure in years. Quarterly compounding, used by most banks, yields slightly higher returns than annual compounding.

Is FD interest taxable, and how much TDS is deducted?

Tap to view the answer

Yes, FD interest is fully taxable as per your income slab. Under Section 194A the bank deducts 10% TDS once the interest it pays you in a financial year exceeds ₹50,000 (₹1,00,000 for senior citizens) — thresholds raised by Budget 2025 from 1 April 2025. Note that the threshold is a trigger rather than an allowance: cross it and the 10% applies to the whole interest, not just the excess. This TDS is a withholding, not your final tax bill — it's adjusted when you file your return.

What is the difference between cumulative and non-cumulative FDs?

Tap to view the answer

A cumulative FD compounds and pays all interest at maturity, giving a higher maturity value. A non-cumulative FD pays interest monthly, quarterly, or annually, suiting those who need regular income. Choose based on whether you need periodic payouts or maximum growth.

Do senior citizens get better FD rates?

Tap to view the answer

Yes, most banks offer senior citizens (60+) an additional 0.25-0.75% interest over standard rates, along with a higher Section 194A TDS threshold of ₹1,00,000 instead of ₹50,000. Always confirm the current rate with your bank, as rates change frequently.

How does compounding frequency affect my FD returns?

Tap to view the answer

More frequent compounding earns slightly more interest, but the difference is smaller than often assumed. On ₹1,00,000 at 7% for 5 years, quarterly compounding matures at about ₹1,41,478 versus ₹1,40,255 for annual compounding — roughly 0.9% more. Most Indian banks compound FD interest quarterly by default.

Understanding Your Results

Maturity Value
The total amount you receive at the end of the tenure, including principal and interest.
TDS Deduction
TDS is bank withholding, not the final tax bill. Under Section 194A the threshold is ₹50,000 for most individuals and ₹1,00,000 for senior citizens (raised by Budget 2025 from 1 April 2025). The threshold is a trigger, not an allowance: once annual interest crosses it, the 10% applies to the whole interest, not only the excess.
Compounding Frequency
Quarterly compounding yields higher returns than annual compounding. Monthly compounding adds 0.3-0.5% effective yield.
Post-Tax Maturity Value
This calculator estimates final tax as the extra tax the FD interest adds on top of the other annual taxable income you enter, under the FY 2026-27 old or new regime. Enter your other income for a realistic figure; with none, the basic exemption and Section 87A rebate can bring the tax to zero.

Key Tips

✓
Senior citizens get 0.25-0.75% higher rates – always check if you qualify.
✓
Quarterly compounding yields the highest returns among common options.
✓
Once annual interest exceeds ₹50,000 (₹1,00,000 for senior citizens), TDS of 10% is deducted on the whole interest; your final tax can still be lower or higher than that withholding.
✓
Cumulative FDs mature higher because interest compounds instead of being paid out: on ₹1,00,000 at 7% for 5 years, about ₹1,41,478 at maturity versus ₹1,35,000 in principal plus payouts — roughly 4.8% more, assuming the payouts are not reinvested.
✓
Compare SBI (6-6.9%), HDFC (6.3-7%), ICICI (6.2-6.8%), Post Office (7.5-7.71%).

Understanding Fixed Deposits in India

What is a Fixed Deposit?

A Fixed Deposit (FD) is a safe investment option where you invest a lump sum for a fixed period at a predetermined interest rate. FDs are offered by banks and post offices with guaranteed returns.

How FD Interest is Calculated

FD interest uses compound interest: A = P(1 + r/n)^(nt), where P is principal, r is annual rate, n is compounding frequency (monthly/quarterly/annual), and t is time in years. Compounding frequency matters, but less than is often claimed: on ₹1,00,000 at 7% for 5 years, quarterly compounding matures at ₹1,41,478 against ₹1,40,255 for annual — about 0.9% more maturity value, or roughly 3% more interest earned. The gap widens with rate and tenure.

Cumulative vs Non-Cumulative FD

Cumulative FD compounds interest and pays at maturity. Non-cumulative pays interest monthly/quarterly. On ₹1,00,000 at 7% for 5 years the cumulative option matures at about ₹1,41,478, against ₹1,35,000 of principal plus payouts on the non-cumulative option — roughly 4.8% more, assuming those payouts are not reinvested elsewhere. Choose cumulative if you do not need the income meanwhile, non-cumulative if you do.

TDS on FD Interest

Under Section 194A, banks deduct 10% TDS once the interest they pay you in a financial year exceeds ₹50,000 (₹1,00,000 for senior citizens) — and the deduction then applies to the whole interest, not just the part above the threshold. That withholding is NOT always your final tax: if your total taxable income is below the relevant exemption / rebate level, the TDS can be refunded after you file your return, or prevented up front with Form 15G/15H. Conversely, if you have salary or other income, your final tax on FD interest can exceed the TDS withheld.

FD Ladder Strategy

Divide total FD amount across different maturities (1, 2, 3, 4 years). Benefit: Portion matures every year for reinvestment, giving access to funds and ability to capture higher rates without locking everything long-term.
