How fixed deposit maturity is calculated
A fixed deposit (FD) pays interest on the amount you lock in for a set period. Banks quote an annual rate; interest is usually compounded quarterly in India, though some FDs compound monthly or yearly.
Maturity = P × (1 + r/n)n×t, where P is deposit, r is annual rate, n is compounding periods per year, and t is years.
This is a planning estimate. Actual maturity can differ slightly due to TDS, premature withdrawal penalties, or scheme rules. For market-linked growth, see SIP or lumpsum calculators; for generic compounding math, try compound interest.
How to use this calculator
- Enter the FD principal (deposit amount) in rupees.
- Set the annual interest rate from your bank (e.g. 7.25 for 7.25% p.a.).
- Choose tenure in years (1, 3, 5 are common FD terms).
- Pick compounding—quarterly is typical for many Indian bank FDs.
- Read maturity amount, interest earned, and the year-wise table.
Worked examples
Sample numbers you can try in the calculator above. Your lender's quote may differ slightly.
₹1 lakh for 3 years at 7.25% (quarterly)
Shows how quarterly compounding builds interest on top of interest over the lock-in.
₹1,00,000 · 7.25% · 3 years · quarterly
Maturity: Maturity ≈ ₹1.24 lakh
₹5 lakh for 5 years at 7%
Larger deposits and longer tenure increase absolute interest earned.
₹5,00,000 · 7% · 5 years · quarterly
Maturity: Maturity ≈ ₹7.03 lakh
₹2 lakh for 1 year at 6.5%
Monthly compounding credits interest more often than annual.
₹2,00,000 · 6.5% · 1 year · monthly
Maturity: Maturity slightly above simple interest
Senior citizen rate (+0.5%)
Many banks add about 0.25–0.50% for senior citizens—adjust the rate field to match your offer.
₹3,00,000 · 7.75% · 2 years
Maturity: Use the +0.5% toggle if your bank pays extra for seniors
Frequently asked questions about the FD calculator
What is an FD calculator?
An FD calculator estimates how much a fixed deposit will grow to at maturity from the deposit amount, interest rate, tenure, and compounding frequency. It helps you compare bank offers before you book an FD.
How is FD interest calculated in India?
Most bank FDs use compound interest. The annual rate is split by how often interest is credited—often quarterly (four times a year). Our formula matches that standard planning math.
Is quarterly or monthly compounding better?
More frequent compounding gives a slightly higher maturity at the same quoted annual rate. The difference is small but real—pick the option that matches your bank's scheme.
Does this FD calculator include TDS tax?
No. It shows gross maturity before tax deducted at source. Interest above certain thresholds may attract TDS—check current rules and your Form 15G/15H eligibility with the bank.
FD vs mutual fund SIP—which should I use?
FDs focus on fixed returns and capital safety within bank limits. Mutual funds carry market risk but may offer higher long-term growth. Use this FD tool for bank FDs and our SIP or lumpsum tools for fund planning.
