Formula & Mathematical Methodology: Section 80C Tax Rebate & Rolling 36-Month Lock-In

Eligible80C = min(12 × P,   ₹1,50,000),   Tax Saved = Eligible80C × Slab × 1.04
Eligible_80C = min(12 × P, 1,50,000); AnnualTaxSaved = Eligible_80C × Slab × 1.04; NetCost = TotalInvested − TotalTaxSaved
  • ₹1,50,000: Maximum combined annual deduction under Section 80C (Old Tax Regime)
  • 1.04: 4% Health and Education Cess multiplier on base income tax

Rounding: Rounded to nearest rupee.

Worked Example: ₹12,500/Month ELSS SIP (₹1,50,000/Yr) for 10 Years at 12% in the 30% Tax Slab

An investor in the 30% tax bracket invests ₹12,500/month into an ELSS fund for 10 years.

  1. Annual Section 80C tax saved = ₹1,50,000 × 31.2% = ₹46,800/year (₹4,68,000 over 10 years).
  2. Net effective out-of-pocket principal = ₹15,00,000 − ₹4,68,000 = ₹10,32,000.
  3. ELSS portfolio compounds at 12% p.a. over 120 months to ₹29,04,239.
Result: Maturity value is ₹29.04 Lakhs plus ₹4.68 Lakhs saved in income tax (net cost ₹10.32L).
