Estimate your FD in four steps
The calculator recomputes live as you change the deposit, rate, tenure or compounding, so you can compare options before you lock your money in.
Enter your deposit
Set the lump sum you want to lock in. A fixed deposit keeps your money safe at a guaranteed rate for the term.
Add the FD rate
Use the annual interest rate your bank offers for the chosen tenure. Senior-citizen rates are usually a little higher.
Choose the tenure
Pick how long to keep the deposit. Longer terms often earn more and let interest compound for longer.
Set compounding
Select how often interest is added back — most banks compound quarterly. See the maturity value update instantly.
How FD interest compounds
A fixed deposit grows through compound interest — the interest each period is added to the balance, so the next period's interest is earned on a slightly larger amount.
Because interest is reinvested, the maturity value is a little higher than simple interest would give — and the more often it compounds, the bigger that effect. The difference is modest at short tenures but adds up over longer terms.
The figure shown is the gross maturity value before any tax. Interest on FDs is taxable, and banks may deduct TDS, so your in-hand amount can be lower.
Maturity formula
A = P × (1 + r ÷ (100 × m))m × t
- PPrincipal — the amount you deposit.
- rAnnual interest rate (%).
- mCompounding periods per year (quarterly = 4, monthly = 12).
- tTenure in years.
Interest earned = maturity amount − principal.
Fixed deposit calculator FAQs
A fixed deposit (FD) is a savings product where you lock a lump sum with a bank or NBFC for a fixed term at a pre-agreed interest rate. In return for keeping the money untouched, you earn a higher, guaranteed rate than a regular savings account — making FDs a popular low-risk option.
This calculator uses the compound-interest formula: Maturity = P × (1 + r ÷ (100 × m))^(m × t), where P is the principal, r is the annual interest rate, m is the number of times interest compounds per year and t is the tenure in years. The interest earned is simply the maturity amount minus your deposit.
Compounding frequency is how often earned interest is added back to the balance so it can itself earn interest. More frequent compounding (monthly vs yearly) produces a slightly higher maturity value for the same rate. Most Indian banks compound FD interest quarterly, which is the default here.
It's a close estimate. Your bank's actual payout can differ because of its specific compounding rules, the exact day-count, and tax deducted at source (TDS) on the interest. PakkaLoan does not quote bank rates — enter the rate from your bank to model your own deposit, and confirm the figure with them.
Yes. Interest earned on a fixed deposit is added to your income and taxed at your slab rate, and banks may deduct TDS once interest crosses the prescribed threshold in a year. This calculator shows the gross maturity value before any tax. For your specific situation, consult a qualified tax adviser.
