Estimate tax amount and total payable for purchases.
The Tax Calculator estimates income tax liability under a progressive (slab-based) tax system. In a progressive system, different portions of income are taxed at different rates — being in a '30% bracket' does not mean paying 30% of your entire income. Only the slice above that threshold is taxed at 30%. This calculator shows your tax by slab, total tax, effective tax rate, and estimated monthly take-home pay. For Indian users, it supports comparison between the Old Regime (with deductions) and the New Regime (lower rates, fewer deductions).
Marginal rate is the rate on your highest income slice. Effective rate is total tax ÷ total income. On ₹16 lakh income in India under the new regime, the marginal rate may be 20% but the effective rate could be 8–10%.
If your total deductions (80C + HRA + 80D + NPS + standard deduction) exceed roughly ₹3–4 lakh, the old regime typically wins. Below that threshold, the new regime's lower rates usually produce less tax.
Surcharge applies in India on income above ₹50 lakh (10% surcharge) and above ₹1 crore (15%). Add this manually on top of the base tax calculation for high incomes.
