Formula & Methodology Behind the Calculator
The calculator uses the compound interest formula:
A = P × (1 + r/n)nt
Where:
- A = Maturity amount
- P = Principal amount (your initial deposit)
- r = Annual interest rate (in decimal)
- n = Number of times interest is compounded per year
- t = Time the money is invested for (5 years)
For Post Office FDs:
- Default compounding is annual (n=1)
- Interest is calculated on a 365-day year basis
- Tax is deducted at source (TDS) if interest exceeds ₹40,000 (₹50,000 for seniors)
