Bank interest above ₹50,000 a year (₹1,00,000 for senior citizens) may have TDS deducted unless you submit Form 15G/15H. FD interest is taxed at your slab rate. Check your bank's current rate before investing.

How FD interest is calculated
For a cumulative fixed deposit, banks add interest to your balance every quarter, and the next quarter's interest is earned on that bigger balance. The formula is: Maturity = P × (1 + r/n)^(n × t), where P is the deposit, r is the annual rate (as a decimal), n is the number of compounding periods per year (4 for quarterly) and t is the tenure in years.
Example: ₹1,00,000 at 7% for 5 years with quarterly compounding gives 1,00,000 × (1 + 0.07/4)^20 ≈ ₹1,41,478. The interest is about ₹41,478. Because of compounding, the effective yearly yield is about 7.19%, a little more than the 7% headline rate.
Non-cumulative FDs pay the interest out monthly or quarterly instead of adding it back, so they earn slightly less overall. FD interest is added to your income and taxed at your slab rate. Banks deduct TDS when interest in a financial year crosses ₹50,000 (₹1,00,000 for senior citizens) unless you submit Form 15G or 15H when eligible.

Frequently asked questions
How is FD interest calculated?
Most Indian banks use quarterly compounding: Maturity = P × (1 + r/4)^(4 × years). This calculator applies that formula by default, and you can switch to monthly, half-yearly or yearly compounding.
What will ₹1 lakh become in an FD in 5 years?
At 7% with quarterly compounding, ₹1,00,000 grows to about ₹1,41,478 in 5 years — roughly ₹41,478 in interest. Enter your bank's actual rate above for an exact figure.
Do senior citizens get a higher FD rate?
Yes, most banks pay senior citizens (60+) about 0.25% to 0.5% more. Tick the senior citizen box to add 0.5%, or type your bank's exact senior rate into the rate field.
Is FD interest taxable?
Yes. FD interest is added to your income and taxed at your slab rate. TDS applies when interest crosses ₹50,000 in a year (₹1,00,000 for senior citizens). A 5-year tax-saver FD qualifies for deduction under Section 80C in the old tax regime.
What is the difference between cumulative and non-cumulative FD?
A cumulative FD adds interest back to the deposit and pays everything at maturity — this is what the calculator shows. A non-cumulative FD pays interest out monthly or quarterly, so you receive regular income but the final amount is lower.
Is this FD calculator free?
Yes. It is free, needs no sign-up and the numbers you enter never leave your browser.
