Frequently Asked Questions

1 How is interest on a Fixed Deposit (FD) calculated?
Fixed Deposit interest is calculated using the compound interest formula: `A = P * (1 + r/n)^(n*t)`, where **A** is the maturity amount, **P** is the principal investment, **r** is the annual interest rate, **n** is the compounding frequency per year, and **t** is the tenure in years.
2 What is the standard compounding cycle for bank FDs?
Most commercial banks calculate compound interest on fixed deposits on a quarterly basis. However, some special schemes offer monthly compounding, half-yearly compounding, or simple interest payouts upon maturity.
3 Can I calculate maturity values for terms specified in days?
Yes. Our tool allows you to specify tenures in days. For short-term deposits (typically under 180 days), banks usually compute simple interest: `A = P * (1 + r * d / 365)`. The tool adapts the formula automatically based on the term and selection.
4 What is the difference between cumulative and non-cumulative FDs?
In a cumulative FD, interest earned is reinvested and compounds periodically, paid out as a lump-sum upon maturity. In a non-cumulative FD, interest is paid out periodically (monthly, quarterly, or half-yearly) to provide regular income, leaving the principal amount unchanged.
5 Are my financial values stored or tracked on your website?
No. All mathematical operations are performed locally on your machine via JavaScript. We do not store, track, or upload any of your interest rates, principal investments, or compound yields.
