Formula & Methodology Behind NSC Interest Calculation
The NSC interest calculator uses the compound interest formula with annual compounding:
A = P × (1 + r/n)nt
Where:
A = Maturity amount
P = Principal investment
r = Annual interest rate (decimal)
n = Number of times interest compounded per year
t = Time in years
For NSC specifically (annual compounding, 5 years):
- n = 1 (compounded annually)
- t = 5 (fixed tenure)
- r = 0.077 (7.7% current rate)
Example Calculation: For ₹1,00,000 investment:
A = 100000 × (1 + 0.077/1)1×5 = ₹1,43,123
The calculator also accounts for:
- Exact day count for interest calculation
- Government’s quarterly rate revisions
- Tax implications under Section 80C
- Comparison with other post office schemes
For verification, you can cross-check calculations using the official RBI’s small savings calculator.
