What the defaults give
₹12,00,000 of income with ₹1,50,000 of deductions leaves ₹10,50,000 taxable.
Old-regime slabs give ₹1,27,500 of tax, and the 4% cess takes the estimate to ₹1,32,600.
The slab structure
Taxable income = max(0, income − deductions)
Up to ₹2,50,000: nil
₹2,50,001 to ₹5,00,000: 5%
₹5,00,001 to ₹10,00,000: 20%
Above ₹10,00,000: 30%
Cess: 4% of the tax
The calculator applies the top slab the income reaches and adds the fixed tax from the slabs below: above ₹10,00,000 that is ₹1,12,500 plus 30% of the excess. It is the same arithmetic as taxing each slice separately, written in a shorter form.
Worked examples
₹12,00,000 − ₹1,50,000 → 30% of ₹50,000 + ₹1,12,500 = ₹1,27,500, plus cess → ₹1,32,600
₹12,00,000 with no deductions → ₹1,72,500 + cess = ₹1,79,400
₹12,00,000 with ₹2,50,000 deductions → ₹1,02,500 + cess = ₹1,06,600
₹6,00,000 with no deductions → 20% of ₹1,00,000 + ₹12,500 = ₹32,500 + cess = ₹33,800
₹3,00,000 with no deductions → 5% of ₹50,000 = ₹2,500 + cess = ₹2,600
₹2,50,000 with no deductions → ₹0
Why the marginal rate is not the rate you pay
At ₹10,50,000 taxable the top slab is 30%, but the total tax of ₹1,27,500 is 12.1% of taxable income. Each slice pays its own rate, so the average is always below the marginal. That is why a raise that pushes income into the 30% band does not cost 30% of the whole salary, only 30% of the amount above the threshold.
Deductions are worth the marginal rate of the income they remove. For someone at the top of the 20% band, ₹50,000 of 80C investments saves about ₹10,400 including cess; for someone in the 30% band the same ₹50,000 saves about ₹15,600. The deduction is most valuable exactly where income is highest, subject to the caps on each section.
What the estimate does not cover
This is the old regime, which allows deductions under sections such as 80C, 80D and house-loan interest. The new regime, which most salaried taxpayers now default to, offers lower slab rates but removes most deductions, so the same income can produce a different bill. Standard deduction, professional tax, rebate under section 87A and surcharge above ₹50 lakh are all outside the model.
Employers deduct TDS monthly on projected annual income, so the monthly figure is an estimate that adjusts as declarations arrive. It is not a final tax — the return reconciles it. Use this as a planning figure for what will be withheld, not as the last word on what you owe.

How much does a ₹50,000 deduction save?
