Calculate the maturity value of a National Savings Certificate at 7.7% (Oct–Dec 2026), compounded yearly over 5 years, with each year’s interest.
Your deposit
The rate is fixed for the whole term when you open the account, even if later rates change.
At maturity
In the old regime the deposit counts for 80C, and so does each year’s interest except the last, as it is treated as reinvested.
Year by year
| Year | Interest that year | Value |
|---|---|---|
| 1 | ₹7,700 | ₹1,07,700 |
| 2 | ₹8,293 | ₹1,15,993 |
| 3 | ₹8,931 | ₹1,24,924 |
| 4 | ₹9,619 | ₹1,34,544 |
| 5 | ₹10,360 | ₹1,44,903 |
The National Savings Certificate (NSC) is a 5-year post office deposit with a fixed rate, 7.7% for Oct–Dec 2026. Interest compounds every year and is paid with the deposit at the end.
There is no upper limit on how much you can put in, and in the old tax regime it counts for the 80C deduction.
Maturity = deposit × (1 + rate)^5

7.7% a year for certificates bought in Oct–Dec 2026, compounded yearly and fixed for 5 years.
Yes, at your slab rate, but in the old regime the interest for the first 4 years also counts as a fresh 80C deduction, which usually cancels the tax on it.
Only in special cases: the holder’s death, a court order, or when a lender enforces a pledge.
NSC locks in for 5 years at 7.7%, with taxable interest. PPF runs for 15 years at 7.1%, entirely tax-free. NSC suits a shorter goal.
