How Post Office RD Returns are Calculated

RD Maturity Formula:

Maturity Amount=P×(1+r)n−11−(1+r)−1/3

  • P = Monthly Deposit

  • r = Quarterly Interest Rate (Annual Rate ÷ 4)

  • n = Total Quarters (Tenure in Years × 4)

Current Post Office RD Interest Rate (2024):

6.7% per annum (compounded quarterly)

Example Calculation:

  • Monthly Deposit (P): ₹5,000

  • Tenure: 5 years (60 months / 20 quarters)

  • Annual Interest Rate: 6.7%

Step 1: Convert annual rate to quarterly rate

r=6.7%4=0.01675 (1.675% per quarter)

Step 2: Apply RD formula

Maturity=5,000×(1+0.01675)20−11−(1+0.01675)−1/3≈∗∗₹3,59,712∗∗

Total Invested Amount:

₹5,000×60=∗∗₹3,00,000∗∗

Interest Earned:

₹3,59,712−₹3,00,000=∗∗₹59,712∗∗
