Calculating Post Office FD Interest Rates
The interest on fixed deposits can be calculated using two methods: the simple interest method and the compound interest method.
1. Simple Interest Calculation
The formula for simple interest is: Simple Interest=𝑃×𝑅×𝑇100Simple Interest=100P×R×T
Where:
- 𝑃P = Principal amount invested
- 𝑅R = Rate of interest (%)
- 𝑇T = Tenure (in years)
For example, if you invest ₹1,000 for 3 years at an interest rate of 7% per annum: Simple Interest=1000×7×3100=₹210Simple Interest=1001000×7×3=₹210
The maturity value would be: Maturity Value=Principal Amount+Simple Interest=₹1000+₹210=₹1210Maturity Value=Principal Amount+Simple Interest=₹1000+₹210=₹1210
2. Compound Interest Calculation
The formula for compound interest is: 𝐴=𝑃(1+𝑟𝑛)𝑛×𝑡A=P(1+nr)n×t
Where:
- 𝐴A = Maturity Amount
- 𝑃P = Principal amount invested
- 𝑟r = Annual interest rate (in decimals)
- 𝑛n = Number of compounding periods per year
- 𝑡t = Number of years
For instance, if you invest ₹1,000 for 5 years at an interest rate of 7.5% per annum compounded quarterly: 𝑃=₹1000P=₹1000 𝑟=7.5%=0.075r=7.5%=0.075 𝑛=4n=4 𝑡=5t=5
𝐴=1000(1+0.0754)4×5=₹1450A=1000(1+40.075)4×5=₹1450
The interest amount would be: Interest Amount=₹1450−₹1000=₹450Interest Amount=₹1450−₹1000=₹450
Using an online Post Office FD Calculator can provide a more accurate and convenient way to determine FD maturity amounts by simply entering the investment amount, rate of interest, and tenure.
