About This Old vs New Regime Tax Calculator
This calculator helps you quickly estimate your income tax under both the Old and New tax regimes for salaried individuals in India (FY 2024-25). Just enter your CTC and eligible deductions, and the tool will show which regime may be more tax-efficient for you.
How This Calculator Works
- CTC is split into 50% basic salary for HRA and NPS calculations (simplified assumption).
- Old regime includes standard deduction (₹50,000) plus your eligible deductions like 80C, 80D, 80G, NPS, HRA, home loan interest, education loan, PF, EPF, gratuity, and professional tax.
- New regime includes standard deduction (₹75,000) and employer NPS (80CCD(2)); most other deductions are not allowed.
- Income tax is calculated slab-wise for both regimes and 4% health & education cess is added.
- Rebate under Section 87A is applied wherever applicable (subject to the respective regime rules).
When Might Old Regime Be Better?
- You fully use Section 80C (PF, ELSS, insurance, etc.).
- You pay high rent and are eligible for a good HRA exemption.
- You have significant home loan interest, NPS, and medical insurance deductions.
- You actively plan investments to maximise deductions every year.
When Might New Regime Be Better?
- You don’t have many deductions or tax-saving investments.
- Your salary structure is simple and you prefer lower tax rates without documentation.
- Your taxable income (after standard deduction) is around lower slabs where new regime rebates help.
