How the FD calculation works

Maturity = P × (1 + r/n)^(n×t) with quarterly compounding typical for Indian bank FDs (n = 4). This tool also applies your tax rate to the interest, showing the after-tax maturity most banks quietly deduct at source.

Worked example

A ₹3,00,000 cumulative FD at 7.1% for 5 years, compounded quarterly, taxed at 10%:

Deposit₹3,00,000
Rate · tenure7.1% · 5 years
Maturity value₹4,26,524
Interest earned₹1,26,524
Post-tax interest (@10%)₹1,13,872

Frequently asked questions

How is FD interest taxed in India?
Interest is added to your income and taxed at slab rates. Banks deduct TDS at 10% when annual interest crosses ₹40,000 (₹50,000 for seniors) — submit Form 15G/15H if your total income is below taxable limits.
What is a cumulative vs non-cumulative FD?
Cumulative FDs reinvest interest and pay everything at maturity — the option this calculator models. Non-cumulative FDs pay interest monthly or quarterly, suiting income needs, but forfeit compounding.
Are FD returns beating inflation?
When inflation runs 5–6%, a 7% FD nets barely 1–2% real return after tax — sometimes negative for higher slabs. FDs buy certainty; equities historically buy growth. Most households need both, sized deliberately.
What happens if I break an FD early?
The rate resets to the card rate for the actual tenure held, minus a 0.5–1% penalty. Emergency buffers belong in liquid funds or sweep-in accounts precisely to avoid these premature-exit haircuts.
