The Post Office RD Maturity Formula Explained
Unlike bank fixed deposits where interest is calculated on a lumpsum, Post Office RDs calculate interest quarterly using the cumulative monthly deposits. The standard formula used under government small savings guidelines is:
$$A = P \times n + P \times \left[ \frac{r}{400} \times \frac{n(n + 1)}{24} \right]$$
(Note: For exact quarterly compounding across 60 monthly intervals, our automated calculation engine calculates compounding cycle yields month-by-month to match official post office passbook ledgers).
Where:
- $A$ = Maturity Amount
- $P$ = Monthly Deposit Amount
- $n$ = Total number of months (60 months for standard tenure)
- $r$ = Annual interest rate (6.7% p.a.)
