FD Calculator 2025 [Fixed Deposit Interest & Maturity Guide]

Use this free FD calculator to compute fixed deposit maturity and interest instantly. Compare FDs, plan returns, and choose the best investment option.

A fixed deposit (FD) is a popular term investment offered by banks and NBFCs, known for offering higher and more stable returns compared to regular savings accounts. The amount you deposit remains locked for a predetermined period, which can range from 7 days to 10 years, depending on the financial institution.

An FD calculator helps you estimate the interest earned and the total maturity amount at the end of your investment period. It is a simple, fast, and reliable tool available here on Paisaseekho.

How Can an FD Calculator Help You?

Calculating the maturity amount manually, especially for long tenures or compound interest, can be time-consuming and complex. An online FD calculator solves this instantly.

Here’s how it helps:

Helps Compare Multiple FD Options

Formula to Determine FD Maturity Amount

There are two types of fixed deposits:

  1. Simple Interest FD
  2. Compound Interest FD

Paisaseekho provides calculators for both.

1. Simple Interest FD Formula

M = P + (P × r × t / 100)

Where:

  • P = Principal amount
  • r = Rate of interest per annum
  • t = Tenure (in years)

Example:
Deposit = ₹1,00,000
Rate = 10%
Tenure = 5 years

Maturity amount:
M = ₹1,50,000

2. Compound Interest FD Formula

M = P × (1 + i/100)ᵗ

Where:

  • P = Principal amount
  • i = Interest rate
  • t = Tenure

Example:
Deposit = ₹1,00,000
Rate = 10%
Tenure = 5 years

Maturity amount:
M = ₹1,61,051

Compound interest typically yields higher returns since interest is calculated on both the initial amount and accumulated interest.
