How it works

- Enter the term in years or months and choose how interest is paid.
- Read the maturity amount, the interest earned and the effective yearly yield.
How banks calculate FD interest
Most Indian banks compound fixed deposit interest every quarter: maturity = P × (1 + r/4)^n, where r is the yearly rate and n the number of quarters. 100,000 at 7% for 1 year becomes 107,185.90, not 107,000, because each quarter's interest earns interest too. For 5 years at 7% it becomes 141,477.82. Terms shorter than 6 months earn simple interest, and a leftover part of a quarter earns simple interest for those months.
Cumulative or payout
In a cumulative FD the interest stays in the deposit and compounds, so you get the most at maturity. In a payout (non-cumulative) FD the interest is paid to your account every month or quarter and the deposit stays the same: 200,000 at 7.2% pays 3,600 a quarter. Banks pay a monthly payout at a slightly discounted rate, so it is a little less than the rate ÷ 12 shown here.
Before you invest
FD interest is taxable, and banks may deduct TDS when your interest for the year crosses the limit set in the Income Tax Act. Breaking an FD early usually costs a penalty of about 0.5–1% of the rate. Senior citizens often get about 0.5% more; enter the rate your bank offers you. Deposits in a bank are insured by DICGC up to ₹5 lakh (500,000) per depositor per bank.

Frequently asked questions
What is the effective yearly yield?
The yearly rate that would give the same growth with yearly compounding. Quarterly compounding at 7% gives an effective yield of about 7.19%, which is useful for comparing deposits that compound differently.
Does it work for post office time deposits?
Post office time deposits also compound quarterly, but interest is paid out yearly, so the amount you receive can differ slightly. Use this as an estimate and check the post office's own rates.
