Method and background

This is what the calculation gives for the numbers you entered. It is an estimate, not advice, and it knows nothing about your situation beyond those numbers. Rules for India change on a published schedule; the effective date is shown on every rule-based tool.

How this is calculated

A tax-saving FD locks money for five years and qualifies for deduction under section 80C up to the annual limit. The arithmetic worth understanding is that the deduction is the main benefit. Interest is taxed at your slab every year on an accrual basis, so at a thirty percent slab a seven percent FD returns under five percent after tax. The upfront deduction, worth thirty percent of the amount invested, dwarfs that. Premature withdrawal is not permitted at all, unlike an ordinary FD.

Method and limits

What it assumes

  • Quarterly compounding, which is the usual bank convention.

What it deliberately does not model

  • The 80C deduction is available only under the old tax regime.

Frequently asked questions

Can I break a tax-saving FD early?
No. The five year lock-in is absolute, unlike an ordinary FD where premature withdrawal is allowed with a penalty.
Is the interest tax free?
No. Only the amount invested gets a deduction. The interest is taxed at your slab each year as it accrues.
