Maturity value
Yearly growth
A Fixed Deposit, or FD, is the most common savings instrument in India. You park a lumpsum with a bank or NBFC for a chosen tenure and earn a fixed rate of interest. Returns are predictable, the deposit is generally safe up to ₹5 Lakh under DICGC insurance, and the rates are typically higher than a savings account.
How compounding affects your FD
The same headline rate produces different maturity values depending on how often interest is compounded. Monthly compounding gives you slightly more than quarterly, which gives you more than yearly. Most Indian banks compound quarterly, so always confirm the frequency before comparing offers.
Formula used
Maturity equals P times (1 plus r divided by n) raised to (n times t). Here, P is the principal, r is the annual rate as a decimal, n is the number of compounding periods per year, and t is the number of years.
Worked example
A ₹1,00,000 FD at 7 percent for 5 years with quarterly compounding matures to about ₹1,41,478. The same FD with monthly compounding grows to roughly ₹1,41,762, and with yearly compounding it ends at about ₹1,40,255.
Frequently asked questions
Yes. FD interest is added to your total income and taxed at your slab rate. Banks deduct TDS at 10 percent if interest crosses ₹40,000 per year (₹50,000 for senior citizens). You can submit Form 15G or 15H if your total income is below the taxable limit.
