Formula & Calculation Methodology
The Post Office RD uses quarterly compounding, which means interest is calculated and added to your principal every 3 months. The exact formula used is:
Maturity Amount = P × [(1 + r/n)^(nt) – 1] × (1 + r/n) / (r/n)
Where:
- P = Monthly deposit amount
- r = Annual interest rate (in decimal)
- n = Number of compounding periods per year (4 for quarterly)
- t = Tenure in years
Key Features of the Calculation:
- Quarterly Compounding: Interest is calculated every 3 months, not annually
- Simple Interest for Partial Periods: If you withdraw before maturity, partial periods earn simple interest
- Government-Backed Rates: Interest rates are set by Ministry of Finance, not market fluctuations
- No TDS: Interest income up to ₹40,000/year is tax-free (₹50,000 for seniors)
The calculator also accounts for:
- Exact number of quarters in your tenure
- Precise interest calculation for each compounding period
- Round-off to nearest rupee as per post office rules
