Guaranteed growth
Safe, predictable, compounded
A fixed deposit locks your money for a set period at a fixed rate, with the interest compounded — typically every quarter. The return is guaranteed and the capital is safe, which makes the FD the bedrock of conservative saving in India.

Lock the principal
Your lump sum is deposited for a fixed tenure at a rate agreed up front.
- 2
Compound quarterly
Interest is added to the balance every quarter, so you earn interest on interest.
- 3
Guaranteed maturity
The maturity value is fixed the day you invest — no market risk.

Mind the tax
Interest is taxable at your slab; TDS applies above ₹40,000 (₹50,000 for seniors).
Questions
Frequently asked
How is FD maturity calculated?
A fixed deposit grows by compound interest. This calculator uses the standard Indian bank convention of quarterly compounding: maturity = P × (1 + r/4)^(4 × years), where P is the principal and r is the annual rate. So ₹1,00,000 at 7% for 5 years matures to about ₹1,41,478. Banks may differ slightly in day-count, but quarterly compounding is the norm.
What is the difference between a cumulative and non-cumulative FD?
In a cumulative FD, interest is reinvested and paid as a lump sum at maturity — this is what the calculator projects. In a non-cumulative FD, interest is paid out periodically (monthly, quarterly or annually), so the principal does not grow. Choose cumulative to maximise the maturity value; non-cumulative for regular income.
Is FD interest taxable?
Yes. FD interest is fully taxable as “income from other sources” at your income-tax slab rate, and banks deduct TDS at 10% if your interest crosses ₹40,000 a year (₹50,000 for senior citizens). The maturity shown here is before tax — your post-tax return will be lower depending on your slab.
Do senior citizens get a higher FD rate?
Yes. Most banks offer senior citizens an extra 0.25%–0.75% over the regular rate. Enter the senior-citizen rate in the calculator to see the higher maturity. Senior citizens also get a larger TDS threshold and a deduction on FD interest under Section 80TTB.
Can I break an FD before maturity?
Usually yes, but premature withdrawal typically attracts a penalty of 0.5%–1% on the applicable rate, and you earn interest only for the period the deposit actually ran. If you might need the money, consider a shorter tenure or a sweep-in FD rather than locking a long deposit.
Is an FD better than a debt mutual fund or RD?
An FD gives guaranteed, predictable returns and capital safety, but the interest is fully taxable. Debt funds can be more tax-efficient over the long term but carry some market risk. An RD suits those saving a fixed amount monthly rather than a lump sum. Compare an RD with our RD calculator.
