Formula & Calculation Methodology
The NSC maturity amount is calculated using compound interest formula with annual compounding:
A = P × (1 + r/n)nt Where: A = Maturity Amount P = Principal (Investment Amount) r = Annual interest rate (7.6% or 0.076) n = Number of times interest compounded per year (1) t = Time in years (5 or 10)
Detailed Calculation Process
- Yearly Breakdown: Interest is calculated annually but added to principal each year
- Tax Treatment: Interest is taxable but qualifies for Section 80C deduction
- Maturity Value: Final amount includes principal + all compounded interest
- Effective Return: Calculated after accounting for tax liability (assuming 30% slab)

How is NSC interest calculated – simple or compound?

- Maturity Payout: Principal + all compounded interest paid at end of term
- Tax Treatment: Interest is taxable annually even though received at maturity
Example: For ₹1,00,000 at 7.6%
- Year 1: ₹1,00,000 + ₹7,600 = ₹1,07,600
- Year 2: ₹1,07,600 + ₹8,178 = ₹1,15,778
- Year 3: ₹1,15,778 + ₹8,800 = ₹1,24,578
- Year 4: ₹1,24,578 + ₹9,470 = ₹1,34,048
- Year 5: ₹1,34,048 + ₹10,188 = ₹1,44,236
