What Is an FD Calculator?
An FD calculator works out the maturity value and interest of a fixed deposit — using your deposit amount, the interest rate and the tenure — and shows the TDS the bank deducts on the interest.
A fixed deposit compounds at a set rate. You place a lump sum for a fixed term and the bank pays a fixed rate, compounded quarterly by default. This calculator turns your deposit into a maturity figure and splits out exactly how much is interest.
FD interest is fully taxable — this is the catch. Unlike PPF or SSY, FD interest is added to your income and taxed at your slab. This calculator goes further than the bank's: set your slab and it shows the real post-tax maturity, not just the 10% TDS the bank withholds.
It shows the real return after tax and inflation. A 7% FD in the 30% bracket is only about 4.9% after tax — and after 6% inflation, roughly −1% real. The calculator gives the post-tax maturity in today's money, so you see whether the deposit actually grows your wealth.
TDS kicks in above ₹50,000 of yearly interest. Banks deduct 10% TDS once your interest from that bank crosses ₹50,000 in a year (₹1 lakh for senior citizens), per Section 194A — the Budget-2025 limit. The calculator computes this year by year and shows what the bank pays after TDS.

How It Works
Calculate Your FD Maturity in Three Steps
02
Set the tenure and compounding
Choose the term in years and months, and the compounding frequency — quarterly is the bank default.
03
Read maturity, interest and TDS
See the maturity value, total interest, the TDS deducted, and what you actually receive after TDS.
Steps to use the FD Calculator: Enter the deposit and rate, Set the tenure and compounding, Read maturity, interest and TDS.
The Formula
How FD Maturity Is Worked Out
01
Compound maturity
Maturity = P × (1 + r/n)^(n × t)
P is the deposit, r the annual rate (e.g. 0.07), n the compounding frequency per year (4 for quarterly), and t the tenure in years. Interest is reinvested each period.
Example: P = ₹5,00,000, r = 7%, n = 4, t = 5 → maturity ≈ ₹7,07,389
02
Effective annual yield
Effective yield = (1 + r/n)^n − 1
Because interest compounds within the year, the true annual return is higher than the quoted rate. At 7% quarterly the effective yield is about 7.19%.
Example: (1 + 0.07/4)^4 − 1 ≈ 7.19%
03
TDS on interest
TDS = 10% × yearly interest (when it exceeds ₹50,000)
Each year the bank checks your interest; if it crosses ₹50,000 (₹1 lakh for seniors) it deducts 10% TDS. The interest is taxable at your slab regardless of TDS.
Example: ₹10 lakh FD at 7% → about ₹41,478 TDS over 5 years
04
Post-tax & real return
Real return = (1 + post-tax yield) ÷ (1 + inflation) − 1
The full tax is interest × your slab × 1.04 (cess), not just the 10% TDS. After that, the real return discounts for inflation — so a 7% FD at the 30% slab is ~4.9% post-tax, about −1% real at 6% inflation.
Example: 4.9% post-tax vs 6% inflation → ≈ −1.0% real
Worked Example
Step-by-Step Walkthrough (₹5 lakh at 7%, 5 years)
Currency note: the example below uses a benchmark scenario priced in Indian Rupee (INR). Values are converted to US Dollar (USD) at the latest exchange rate so you can compare against your own numbers.
Scenario
A 5-year fixed deposit of $500,000.00 at 7%, compounded quarterly.
1
Step 1 · Compound quarterly
At 7% compounded four times a year, the deposit grows to an effective 7.19% a year.
Effective yield ≈ 7.19%
2
Step 2 · Maturity value
Over 5 years the $500,000.00 deposit grows to its maturity value.
Maturity = $707,389.00
3
Step 3 · Interest & TDS
The gap is interest. Yearly interest here stays under the ₹50,000 limit, so no TDS is deducted — but the interest is still taxable.
Interest $207,389.00 · You get $707,389.00
The takeaway
A ₹5 lakh FD at 7% returns about $707,389.00 in 5 years — $207,389.00 of it interest. No TDS applies here because yearly interest stays under ₹50,000, but remember the interest is fully taxable at your slab, so the real return is lower than a tax-free PPF.

Common Mistakes
FD Mistakes to Avoid
Treating the maturity as tax-free
Why it matters
FD interest is fully taxable at your slab. People who plan on the headline maturity over-estimate what they keep — a 30%-bracket saver loses nearly a third of the interest to tax.
Fix
Set your slab; the calculator shows the real post-tax maturity and the after-inflation return, so you plan on what you actually keep, not the gross figure.
Forgetting TDS above ₹50,000
Why it matters
Once yearly interest crosses ₹50,000 (₹1 lakh for seniors), the bank deducts 10% TDS. People are surprised when their payout is smaller than the calculator on the bank site showed.
Fix
This calculator computes TDS year by year and shows what you actually receive. Submit Form 15G/15H if your income is below the taxable limit.
Ignoring compounding frequency
Why it matters
A monthly-compounding FD earns more than a yearly one at the same rate. Comparing two banks on the quoted rate alone misses the difference.
Fix
Compare on the effective yield this calculator shows, not just the quoted rate.
Breaking the FD early
Why it matters
Premature withdrawal cuts the rate and adds a 0.5–1% penalty, so you earn far less than the maturity figure suggests.
Fix
Pick a tenure you can commit to. For money you might need, keep a separate liquid fund instead of one long FD.
Putting long-term money in an FD
Why it matters
For 10–15 year goals, a taxable FD usually loses to tax-free PPF/SSY or to equity. FDs suit safety and short horizons, not long-term wealth.
Fix
Use this calculator for short-term safety, and the PPF or SSY calculators for long-term tax-free goals.
Pro Tips
Get More From Your FD
Compare effective yield
Two banks at the same rate can pay differently if one compounds monthly and the other quarterly. Compare the effective yield, not the headline rate.
Submit Form 15G or 15H
If your total income is below the taxable limit, file Form 15G (under 60) or 15H (senior) so the bank does not deduct TDS.
Use a tax-saver FD for 80C
A 5-year tax-saver FD gives a Section 80C deduction up to ₹1.5 lakh on the old regime — useful if you have unused 80C room.
Ladder your deposits
Split money across FDs of different tenures so some mature each year. You get liquidity without breaking a single large FD.
Claim the senior-citizen edge
Senior citizens earn about 0.5% more and enjoy a ₹1 lakh TDS-free interest limit — set the option so the TDS is right.

Glossary
Key FD Terms
Every important term you'll encounter in this calculator and the broader topic.
- Fixed Deposit (FD)
- A bank deposit locked for a fixed term at a fixed interest rate. A cumulative FD reinvests interest and pays it all at maturity.
- Maturity Value
- The total amount paid at the end of the term — your deposit plus all the compounded interest, before tax.
- Effective Annual Yield
- The true yearly return after compounding within the year. It is higher than the quoted rate when interest compounds quarterly or monthly.
- TDS (Section 194A)
- Tax deducted at source by the bank — 10% on FD interest above ₹50,000 a year (₹1 lakh for seniors). It is adjustable against your final tax.
- Form 15G / 15H
- Declarations you give the bank to stop TDS when your income is below the taxable limit — 15G for under-60s, 15H for senior citizens.
- Tax-Saver FD
- A 5-year FD eligible for a Section 80C deduction up to ₹1.5 lakh (old regime), with a 5-year lock-in. The interest is still taxable.
- Post-Tax Return
- The yield after the full slab tax on interest — not just the 10% TDS. A 7% FD at the 30% slab gives about 4.9% post-tax.
- Real Return
- The post-tax return after inflation. For a 20–30% bracket saver, an FD's real return is often near zero or negative.
Help & answers
Frequently asked questions
Everything you need to know about how the FD Calculator works.
01What is an FD calculator?
An FD calculator works out what a fixed deposit grows to at maturity. You enter the deposit amount, interest rate and tenure; it returns the maturity value, the interest earned, and the TDS the bank deducts on that interest.
02How is FD maturity calculated?
Maturity = P × (1 + r/n)^(n × t), where P is the deposit, r the annual rate, n the compounding frequency (4 for quarterly), and t the years. Indian banks compound quarterly, so ₹5 lakh at 7% for 5 years grows to about ₹7.07 lakh.
03What is the maturity of ₹5 lakh FD at 7%?
₹5 lakh at 7% for 5 years, compounded quarterly, matures at about ₹7,07,389 — roughly ₹2,07,389 of interest. The effective annual yield is about 7.19% because the interest compounds four times a year.
04Is FD interest taxable?
Yes, fully. FD interest is added to your income and taxed at your slab rate — there is no exemption. This is the key difference from PPF and SSY, whose interest and maturity are completely tax-free.
05What is the post-tax return on an FD?
Your rate minus your slab tax. A 7% FD in the 30% bracket gives a post-tax return of about 4.9% (7% × 0.70); at 20% it is about 5.6%. The 10% TDS is only withholding — set your slab here to see the true post-tax return.
06Do FDs beat inflation?
Often not, after tax. At 7% in the 30% slab the post-tax return is ~4.9%; against 6% inflation that is about −1.1% real — your purchasing power falls. FDs suit safety and short terms, not long-term real growth.
07What is the TDS on FD interest?
Banks deduct TDS at 10% once your interest from that bank in a financial year crosses ₹50,000 (₹1 lakh for senior citizens) — thresholds raised by Budget 2025. Without a PAN it is 20%. The TDS is adjustable against your final tax.
08How can I avoid TDS on my FD?
Submit Form 15G (under 60) or Form 15H (senior citizen) to the bank if your total income is below the taxable limit — then no TDS is deducted. Spreading deposits across banks to stay under the limit also helps, but the interest remains taxable.
09How often is FD interest compounded?
Most Indian banks compound FD interest quarterly. More frequent compounding (monthly) gives a slightly higher maturity; less frequent (yearly) gives a little less. This calculator lets you pick the frequency your bank uses.
10FD vs PPF — which is better?
An FD is liquid and flexible but its interest is fully taxable; PPF locks money for 15 years but is tax-free (EEE) and currently pays 7.1%. For short-term or emergency money, choose an FD; for long-term tax-free growth, PPF usually wins.
11Do senior citizens get higher FD returns?
Yes. Banks typically pay senior citizens about 0.5% more on FDs, and the TDS-free interest limit is higher — ₹1 lakh a year versus ₹50,000. Enter your actual rate and tick the senior-citizen option for the right TDS limit.
12What is a tax-saver FD?
A tax-saver FD is a 5-year fixed deposit that qualifies for a Section 80C deduction up to ₹1.5 lakh (old regime). It has a 5-year lock-in and the interest is still taxable, but the deposit reduces your taxable income.
13What is a cumulative vs non-cumulative FD?
A cumulative FD reinvests interest and pays it all at maturity — this calculator models that. A non-cumulative FD pays interest out monthly or quarterly instead, so the balance does not compound. Choose cumulative for maximum growth.
14Is there a penalty for breaking an FD early?
Usually yes — banks charge a premature-withdrawal penalty of about 0.5–1% lower interest, and you only get the rate for the period the money actually stayed. Plan the tenure carefully so you do not need to break it.
15Is this FD calculator free and accurate?
Yes — it is free, needs no sign-up, and runs in your browser. It uses the standard quarterly-compounding FD maths that banks use, and the FY 2025-26 TDS rules. Confirm your exact rate and compounding with your bank before investing.
