Calculation Methodology & Rules

The FD Calculator computes the maturity value, total interest earned, and effective annual yield of your fixed deposit scheme.

1. Compound Interest Formula (Standard)

For a standard compound interest FD, the future maturity value is:

M = P × (1 + r / f)f × t

Where:

  • P: Principal deposit amount (₹)
  • r: Expected annual return rate as a decimal (Annual Rate % / 100)
  • f: Compounding frequency per year (12 for monthly, 4 for quarterly, 2 for half-yearly, 1 for annually)
  • t: Investment tenure in years

2. Simple Interest Formula

For short-term FDs (less than 6 months) or simple interest deposits:

M = P × (1 + r × t)

TDS Compliance Note

Interest earned on FDs is subject to TDS under Section 194A if it exceeds ₹40,000 (₹50,000 for seniors) per financial year. You can estimate your tax obligations using our standalone TDS Calculator.

Frequently Asked Questions

FD maturity is calculated based on compound or simple interest. In India, most bank fixed deposits compound quarterly. The formula for quarterly compound interest is Maturity = Principal × (1 + R/400)^(4 × Years).

Yes, the interest earned on bank fixed deposits is fully taxable under the head 'Income from Other Sources' in your tax return, as per your marginal income tax slab. It is not tax-free.

Under Section 194A of the Income Tax Act, banks deduct TDS (Tax Deducted at Source) at 10% if your annual interest income from all FDs in a bank exceeds ₹40,000 (₹50,000 for senior citizens aged 60 and above). If your PAN is not provided, TDS is deducted at 20%.

If your total annual income is below the taxable threshold, you can submit Form 15G (Form 15H for senior citizens) to the bank at the start of the financial year to request them not to deduct TDS.
