What this calculator does

A fixed deposit (FD) locks a sum with a bank for a set period at a fixed rate. Most Indian banks compound FD interest quarterly; this calculator shows the maturity value for the rate and compounding you choose.

What your result means

The maturity value follows directly from your principal, rate, compounding frequency and duration. It is what the numbers show under these assumptions, not a promised outcome.

Formula

1. Compound interest

A = P × (1 + r ÷ m)^(m × t)

Symbols

A
Maturity value (₹)
P
Principal (₹)
r
Annual rate (decimal)
m
Compounding periods per year
t
Years

Why this formula works

Each period adds interest at r ÷ m on the balance so far, so the balance multiplies by (1 + r ÷ m) m × t times.

Unit check

₹ = ₹ × (pure ratio). ✓

Worked example

P = ₹1,00,000, 7%, quarterly (m = 4), 5 years: A = 1,00,000 × 1.0175²⁰ ≈ ₹1,41,478.

Common mistakes

Using the annual rate per period. Forgetting to multiply years by the compounding frequency. Confusing simple and compound interest.

Working for your numbers

  1. Rate per period = 7% ÷ 4 = 1.7500%
  2. Periods = 4 × 5 = 20
  3. Growth factor = (1 + 0.017500)^20 = 1.414778
  4. A = ₹1,00,000 × 1.414778 = ₹1,41,478
  5. Interest = ₹1,41,478 − ₹1,00,000 = ₹41,478

Frequently asked questions

Is FD interest taxable?

Yes. FD interest is added to your income and taxed at your slab rate, and banks deduct TDS above the threshold. This calculator shows pre-tax figures.

Is my FD insured?

DICGC insures up to ₹5 lakh per depositor per bank, including interest.

Is the rate on this page guaranteed?

No. The rate is your own input. Banks and markets set actual rates, and they can change. This page shows what the numbers give under your assumptions.

When should I talk to a professional instead?

Before a real borrowing or investment decision, check the lender's Key Facts Statement or speak to a qualified adviser. This page is educational and does not consider your full situation.
