Estimating tax on FD interest across a financial year
Interest accrues across every deposit you hold
For Tax Year 2026-27, sum expected interest from all FDs—not just the one that matures in March. Cumulative FDs still create taxable interest even when cash arrives only at maturity. Use each deposit’s rate and tenure in the FD calculator, then add the interest figures for a yearly total.
TDS is not the full story
Banks may deduct TDS when interest crosses thresholds, subject to declarations like Form 15G/15H where eligible. Your slab rate can mean more tax (or a refund) when you file. Sketch the interest as other income in the income-tax calculator alongside salary for a rough bill.
Do this before year-end laddering
Renewals in late March can shift which FY shows the interest. If you are close to a surcharge or rebate edge, timing and breaking deposits have consequences—confirm with statements and a professional for large piles. The calculators give planning arithmetic, not a filed return.
