Using the National Savings Certificate (NSC) Calculator
Enter a qualifying deposit and the rate attached to your certificate’s issue period. The annual accrual list separates the original investment from interest added each year, helping you distinguish compounding from periodic income.

Method and assumptions
Editable rates start from the October–December 2026 small-savings rate table. Use the rate applicable to your issue; future rates are not guaranteed. Five-year term, annual compound accrual, paid at maturity; no periodic cash payout or reinvestment after year five. Accrual is an estimate before account rounding. Tax deductions and taxation of interest depend on circumstances and are not calculated.

Separate contributions from growth
An ending balance can grow because you put more money in, because the assumed return is higher, or because the money has more time to compound. Those are different effects. Keep the contribution schedule consistent when comparing rates, and distinguish a mathematical projection from a return that is contractually guaranteed. Fees and taxes need their own assumptions.
Common question
Does the NSC calculator show the tax deduction I can claim?
No. It shows compound interest and maturity arithmetic. Whether a deposit or accrued interest qualifies for a deduction depends on the applicable regime, limits and your circumstances. Do not treat the annual accrual table as a tax filing schedule.
