Module C: Formula & Methodology Behind the Calculator
Our calculator uses the exact formulas prescribed by the Central Board of Direct Taxes (CBDT) for FY 2024-25. Here’s the detailed methodology:
1. Salary Structure Calculation
For ₹1 lakh CTC/month (₹12 lakh annually), we assume this standard structure:
- Basic Salary: 40% of CTC (₹48,000/month)
- HRA: 40% of Basic (₹19,200/month) – adjustable
- Special Allowance: Balance amount
- Employer PF: 12% of Basic (₹5,760/month)
- Employee PF: 12% of Basic (₹5,760/month)
2. Taxable Income Calculation
The formula for taxable income is:
Taxable Income = (Annual CTC - Employer PF - Standard Deduction) - (Exemptions + Deductions) Where: - Standard Deduction = ₹50,000 (both regimes) - Exemptions = HRA + LTA + Others - Deductions = 80C + 80D + 80CCD + Others
3. HRA Exemption Calculation
HRA exemption is the minimum of:
- Actual HRA received
- 50% of salary (for metro cities) or 40% (non-metro)
- Actual rent paid minus 10% of salary

How is HRA exemption calculated for ₹1 lakh CTC?
The HRA exemption is the minimum of these three amounts:
- Actual HRA received (e.g., ₹20,000/month)
- 50% of basic salary (for metro cities) or 40% (non-metro)
- For ₹48,000 basic: ₹24,000 (metro) or ₹19,200 (non-metro)
- Actual rent paid minus 10% of basic salary
- Example: ₹18,000 rent – ₹4,800 (10% of basic) = ₹13,200
In this case, the exemption would be ₹13,200/month (assuming metro city).
Critical: You must submit rent receipts and have a valid rent agreement for claims above ₹3,000/month.
What are the common mistakes people make with ₹1 lakh CTC tax planning?
Avoid these 5 costly errors:
- Not submitting investment proofs: Many assume declarations are enough, but without proofs, you’ll pay tax on the full amount
- Ignoring HRA benefits: Not claiming HRA when eligible can cost you ₹15,000-₹25,000 annually
- Choosing wrong regime: Sticking with old regime without enough deductions costs extra tax
- Missing standard deduction: Both regimes offer ₹50k standard deduction – ensure it’s applied
- Not verifying Form 16: 30% of employees find discrepancies in their Form 16 that affect refunds
Solution: Use our calculator monthly to track your tax liability and adjust investments accordingly.
How does provident fund (PF) affect my ₹1 lakh CTC?
PF impacts your take-home in two ways:
1. Employee PF Contribution (Deducted from salary):
- 12% of basic salary (₹48,000 basic = ₹5,760/month)
- This reduces your take-home but builds retirement corpus
- Earns 8.15% interest (2024 rate) – tax-free
2. Employer PF Contribution (Part of CTC but not taxable):
- Also 12% of basic (₹5,760/month)
- Not counted as taxable income
- Reduces your taxable income by ₹69,120 annually
Important: You can opt out of PF if your basic salary exceeds ₹15,000/month, but this is generally not recommended due to the forced savings benefit.
