FD Calculator
Fixed deposit maturity and post-tax return.
How this is calculated
Standard quarterly-compounding FD formula: maturity = principal × (1 + rate/4)^(4×years). Interest is taxed at your marginal slab in the year it accrues (banks deduct TDS above the threshold), so the post-tax value is what you actually keep.
Tax treatment
FD interest is added to your income and taxed at your full marginal slab every year it accrues, not just at maturity — there is no LTCG concession for fixed deposits, which is why they are tax-inefficient for high earners.
