What this means

M is the maturity amount; interest earned = M − P. Quarterly compounding yields slightly more than annual at the same nominal rate, which is why banks quote both the rate and the effective yield.

3 Important insights
  • Inflation often matters more than expected over the long run.
  • Small rate changes can significantly affect total outcomes.
  • Long-term consistency usually beats short-term timing.

Small, consistent changes compound: time in the market usually beats timing the market.

How it works

M = P × (1 + r/n)n·t — P principal, r annual rate, n compounding periods per year (quarterly = 4), t years. Interest earned = M − P.

Example

₹1,00,000 at 7% compounded quarterly for 5 years matures to ≈ ₹1,41,478 — about ₹41,478 interest.

Frequently asked questions

Why quarterly compounding?+

Most banks compound fixed-deposit interest quarterly by default, which is why it is the default here. Switch to monthly, half-yearly or annual to match your bank.

Is FD interest taxed?+

Yes — fixed-deposit interest is taxable as income, and banks deduct TDS once annual interest crosses the threshold. This calculator shows the pre-tax maturity value.

Quick answers

Short, sourced answers to the questions people (and AI assistants) ask most.

What is FD?
A fixed deposit (FD) calculator projects the maturity value and interest earned on a lump-sum bank deposit held for a fixed term at a fixed rate, with interest usually compounded quarterly.
Why does FD matter?
M is the maturity amount; interest earned = M − P. Quarterly compounding yields slightly more than annual at the same nominal rate, which is why banks quote both the rate and the effective yield.
How is FD calculated?
Interest compounds on the principal at the bank's stated rate. With quarterly compounding, the rate is divided by four and applied four times a year, so each quarter's interest itself earns interest. Formula: M = P × (1 + r/n)^(n·t) (P = principal, r = annual rate, n = compounding periods/year, t = years).
What is a good fd?
FD rates vary by bank, tenure, and whether you are a senior citizen (who typically get a small premium); interest is taxable as income and banks deduct TDS above the threshold.
What are common fd mistakes?
Ignoring tax: FD interest is fully taxable and TDS is deducted above the annual threshold, lowering the real return.
When should you use the FD Calculator?
Use it to compare FD tenures and banks, decide between cumulative (interest reinvested) and payout options, or estimate post-tax returns on a deposit.

What is the FD Calculator?

A fixed deposit (FD) calculator projects the maturity value and interest earned on a lump-sum bank deposit held for a fixed term at a fixed rate, with interest usually compounded quarterly.

How the FD Calculator works

Interest compounds on the principal at the bank's stated rate. With quarterly compounding, the rate is divided by four and applied four times a year, so each quarter's interest itself earns interest.

M = P × (1 + r/n)^(n·t) (P = principal, r = annual rate, n = compounding periods/year, t = years)

What's a typical value?

FD rates vary by bank, tenure, and whether you are a senior citizen (who typically get a small premium); interest is taxable as income and banks deduct TDS above the threshold.

FD maturity per ₹1,00,000 (compounded quarterly)

6%₹1,19,562₹1,34,686₹1,81,402
7%₹1,23,144₹1,41,478₹2,00,160
8%₹1,26,824₹1,48,595₹2,20,804

Worked example

₹1,00,000 at 7% p.a., compounded quarterly for 5 years: Maturity ≈ ₹1,41,478 Interest earned ≈ ₹41,478

Common mistakes to avoid

  • Ignoring tax: FD interest is fully taxable and TDS is deducted above the annual threshold, lowering the real return.
  • Overlooking premature-withdrawal penalties that reduce the effective rate.
  • Comparing nominal rates instead of effective yield across different compounding frequencies.
