What is FD
An FD calculator, or fixed deposit calculator, is an online financial tool designed to help you estimate the maturity amount and interest earnings on a fixed deposit investment. Whether you're an individual investor or a senior citizen seeking stable returns, the fixed deposit calculator online provides quick and accurate results without the hassle of manual computation.
This tool is especially useful when comparing deposit tenures, interest rates, and compounding frequencies. It simplifies decision-making by helping you understand exactly how much your investment will grow over time.
There’s also a special version known as the senior citizen FD calculator, which factors in higher interest rates typically offered to senior citizens by banks and NBFCs.
How Does a Fixed Deposit Interest Calculator Work?
The formula used in most FD calculators is:
A = P × (1 + r/n)^(n × t)
Where:
A = Maturity Amount
P = Principal amount (initial investment)
r = Annual interest rate (in decimal)
n = Number of times interest is compounded per year
t = Tenure (in years)
For example, if you invest ₹1,00,000 at 7% annual interest compounded quarterly for 3 years: A = 1,00,000 × (1 + 0.07/4)^(4×3) ≈ ₹1,23,000
Using a fixed deposit return calculator like this saves time and improves financial planning.
