About the Tax Calculator

The Tax Calculator estimates your income tax liability across multiple regimes — including India's new and old tax regimes, the US Federal system, and the UK — so you can compare and plan effectively before filing. It applies the correct tax slabs, standard deductions, surcharges, and cess automatically, giving you your total tax payable, effective tax rate, and monthly take-home in seconds. This tool is especially valuable for Indian salaried individuals deciding between the old and new regime each financial year.

How to Use

Select your Tax Regime / Country (e.g., India — New Regime).
Enter your Annual Gross Income before any deductions.
For the Old Regime, enter total deductions under 80C, 80D, HRA, and other sections.
Click Calculate Tax to see your payable tax, effective rate, and take-home breakdown.

Formula / Methodology

India New Regime (FY 2024-25):
  Std. Deduction: ₹75,000
  Slabs: 0% / 5% / 10% / 15% / 20% / 30%
  Rebate 87A: Tax = 0 if income ≤ ₹7 L

India Old Regime:
  80C limit: ₹1,50,000
  Std. Deduction: ₹50,000
  Slabs: 0% / 5% / 20% / 30%

Effective Rate = (Tax ÷ Gross Income) × 100
Health & Education Cess: 4% on tax + surcharge

Under the Old Regime you can claim deductions (80C investments, 80D health insurance, HRA exemption) to reduce taxable income, whereas the New Regime offers lower slab rates with minimal deductions.

Understanding Your Results

Total Tax Payable The total income tax due for the financial year, including applicable surcharge and 4% Health & Education Cess for Indian regimes. This is the amount you need to pay via advance tax or TDS.

Effective Tax Rate % Your actual average tax rate as a percentage of gross income — always lower than the highest slab rate. Use this to compare the real cost of different regimes on your specific income.

Monthly Take-Home Your estimated monthly in-hand salary after tax. Use this figure for budgeting and financial planning, and compare it between regimes to choose the one that maximises your take-home pay.
