What is a Lumpsum Calculator for Fixed Deposit?

A lumpsum FD calculator helps you calculate the final maturity value of your investment after a fixed period at a fixed interest rate. Banks usually offer FD interest in:

  • Monthly compounding
  • Quarterly compounding
  • Half-yearly compounding
  • Yearly compounding

A lumpsum FD calculator uses the appropriate compounding method to calculate maturity value accurately.

Why Do You Need an FD Lumpsum Calculator?

  • To estimate future maturity value
  • To calculate total interest earned
  • To compare FD rates of different banks
  • To plan long-term financial goals
  • To calculate senior citizen FD returns
  • To understand compounding differences
  • To compare FD with RD, mutual funds, gold, and stocks

Formula Used in FD Lumpsum Calculator

The formula depends on compounding type. The standard compounding formula is:

A = P × (1 + r/n)^(n×t)

A = Maturity Amount  
P = Principal (your investment)  
r = Annual interest rate  
n = Compounding frequency (1, 4, 12, etc.)  
t = Time (in years)

This formula is used by all banks and financial institutions.

Example of FD Lumpsum Calculation

Let’s say you invest ₹1,00,000 at 7% annual interest for 5 years (compounded quarterly).

Here:

  • P = ₹1,00,000
  • r = 7% = 0.07
  • n = 4
  • t = 5

Using the formula, maturity amount ≈ ₹1,40,256

Total interest earned = ₹40,256
