A Fixed Deposit (FD) Calculator is a smart online tool designed to help investors calculate the final maturity value of their fixed deposit investment. It eliminates manual calculations and provides instant, accurate results based on the principal amount, interest rate, duration, and compounding frequency.
A Fixed Deposit is one of the most popular and safest investment options offered by banks and financial institutions. When you invest a lump sum amount for a fixed period, your money earns interest at a pre-decided rate. The interest is compounded periodically (monthly, quarterly, half-yearly, or annually) and added to your investment, growing your corpus over time.
The formula used to calculate compound interest in a fixed deposit is:
Maturity Amount (A) = P × (1 + r/n)nt
Where:
P = Principal amount (Initial investment)
r = Annual interest rate (in decimal)
n = Number of compounding periods in a year
t = Time period in years
Suppose you invest ₹1,00,000 for 3 years at an annual interest rate of 6.5% compounded quarterly. Then:
Maturity Amount = ₹1,00,000 × (1 + 0.065 / 4)4×3 ≈ ₹1,21,000
Interest Earned = ₹21,000
Yes, FDs are one of the safest investment avenues. Most bank FDs are insured up to ₹5 lakh under DICGC.
This depends on the tenure, the bank, and your customer type (e.g., senior citizens get better rates). Private banks and NBFCs may offer slightly higher rates than public banks.
Interest can be compounded monthly, quarterly, half-yearly, or annually based on the product chosen. Quarterly compounding is most common.
Yes, but premature withdrawals may attract penalties and lower interest earnings. Consider your liquidity needs before choosing a tenure.
Yes. Interest earned on FDs is fully taxable under the head "Income from Other Sources" as per your income tax slab. If total interest exceeds ₹40,000 (₹50,000 for senior citizens), TDS is applicable.
