• 1-year FD only
• Entire income taxed at normal slab rates (no special capital gains / lottery rates)
• Taxpayer is a resident individual

Gross interest (1 year)
Tax on income without FD
Tax on income with FD
Incremental tax due to FD
Net FD interest after tax

Tax logic: Uses New Tax Regime slabs for FY 2025-26,
Section 87A rebate (up to ₹60,000 up to ₹12L) with marginal relief till ~₹12.75L,
surcharge of 10%/15%/25% on tax for incomes above ₹50L/₹1Cr/₹2Cr with marginal relief,
plus 4% health & education cess. Assumes only normal slab income. For complex situations
(capital gains, non-resident, multiple regimes), please confirm with a tax professional.
