In this complete 2025 guide, we’ll explain how the Income Tax Calculator works, what factors affect your tax amount, and how to plan your taxes better under both the old and new regimes.
What Is an Income Tax Calculator?
An Income Tax Calculator is an online tool that helps you calculate the amount of tax payable on your income after considering exemptions, deductions, and applicable tax slabs. It saves you from manual calculations and provides instant, accurate results based on the latest tax rules announced by the Government of India.
It’s especially useful for individuals trying to compare between the Old Tax Regime and the New Tax Regime introduced under Section 115BAC.
How Does an Income Tax Calculator Work?
The calculator works by taking your annual income, deductions, allowances, and tax regime preference as inputs. It then applies the respective tax slabs and shows you:
- Total Taxable Income
- Total Tax Payable
- Tax Rebate (if applicable)
- Effective Tax Rate
- Comparison of Old vs New Regime Tax

Example of Income Tax Calculation
Let’s say your annual salary is ₹10,00,000 and you claim deductions worth ₹1,50,000 under Section 80C, and ₹25,000 under Section 80D.
- Total Income: ₹10,00,000
- Total Deductions: ₹1,75,000
- Taxable Income: ₹8,25,000
Now apply the Old Regime slabs:
- ₹2.5L – ₹5L → 5% = ₹12,500
- ₹5L – ₹8.25L → 20% = ₹65,000
- Total Tax = ₹77,500 + 4% Cess = ₹80,600
Under the New Regime (no deductions), tax = ₹45,000 + 4% cess = ₹46,800. Hence, the New Tax Regime is more beneficial here.
