About Tax Saver FD Return Calculator

A tax-saver deposit gives a deduction on the amount invested but the interest remains fully taxable each year. For a top-rate taxpayer the post-tax return often falls below inflation, which is the trade for the upfront relief and the five-year lock-in.

Formula

Post-tax return

Net maturity = M - (M - P) × tax rate; post-tax CAGR = (Net/P)^(1/t) - 1

Frequently Asked Questions

Is the deposit itself tax free?

The investment attracts a deduction within the overall limit, but the interest is taxed at your slab rate every year.

Can it be withdrawn early?

No. The statutory lock-in cannot be broken, and the deposit cannot be pledged as security.
