FD Calculator
Fixed deposit maturity and post-tax return.
Fixed deposit maturity and post-tax return.
The FD Calculator takes your own numbers and projects the result using the method described below, showing every assumption rather than a single opaque figure.
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.
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.
Is the FD Calculator's result a fixed outcome?
No — every figure here is an illustrative projection based on the assumptions you enter, not a promised or fixed return. Change any input to see how the result moves.
Is tax already accounted for?
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.
