Module C: Formula & Methodology Behind the Calculator
Our calculator uses the exact methodology prescribed in the Income Tax Act, 1961 as amended by Finance Act 2024. Here’s the detailed calculation process:
1. Gross Total Income Calculation
GTI = Income from Salary + Income from House Property + Income from Business/Profession + Capital Gains + Other Sources
2. Deductions Application
For Old Regime:
Taxable Income = GTI – Standard Deduction (₹50,000) – Section 80C (max ₹1,50,000) – HRA Exemption – Other Chapter VI-A Deductions
For New Regime:
Taxable Income = GTI – Standard Deduction (₹50,000) – [Limited deductions as per Section 115BAC]
3. Tax Calculation Based on Slabs
New Tax Regime Slabs (2024-25):
| Income Range (₹) | Tax Rate | Marginal Relief |
|---|---|---|
| 0 – 3,00,000 | 0% | N/A |
| 3,00,001 – 6,00,000 | 5% | N/A |
| 6,00,001 – 9,00,000 | 10% | N/A |
| 9,00,001 – 12,00,000 | 15% | N/A |
| 12,00,001 – 15,00,000 | 20% | N/A |
| Above 15,00,000 | 30% | Available |
Old Tax Regime Slabs (2024-25):
| Age Group | Income Range (₹) | Tax Rate |
|---|---|---|
| Below 60 | 0 – 2,50,000 | 0% |
| 2,50,001 – 5,00,000 | 5% | |

| Above 10,00,000 | 30% | |
| 60-80 | 0 – 3,00,000 | 0% |
| 3,00,001 – 5,00,000 | 5% | |
| 5,00,001 – 10,00,000 | 20% | |
| Above 10,00,000 | 30% | |
| Above 80 | 0 – 5,00,000 | 0% |
| 5,00,001 – 10,00,000 | 20% | |
| Above 10,00,000 | 30% |
4. Surcharge Calculation
Applied on income tax (before cess) for high earners:
- 10% for income between ₹50 lakh – ₹1 crore
- 15% for income between ₹1 crore – ₹2 crore
- 25% for income between ₹2 crore – ₹5 crore
- 37% for income above ₹5 crore

Module G: Interactive FAQ on Post-Budget Tax Calculation
1. How do I know whether to choose the old or new tax regime after the budget changes?
The choice depends on your income level and eligible deductions. Here’s a quick decision guide:

- You prefer simpler compliance with fewer documents
- Choose Old Regime if:
- You have significant deductions (home loan, education loan, etc.)
- Your income is above ₹15 lakh (higher deductions offset surcharge)
- You’re a senior citizen with medical expenses
Use our calculator to run both scenarios with your actual numbers. The budget 2024 made the new regime the default, but you can still opt for the old regime by filing Form 10-IE.

Example Calculation:
For taxable income of ₹20,00,000 under new regime:
- Income tax: ₹3,60,000 (₹3L at 0% + ₹3L at 5% + ₹3L at 10% + ₹3L at 15% + ₹5L at 20% + ₹3L at 30%)
- Surcharge: ₹90,000 (25% of ₹3,60,000)
