The Two Regimes
New: Lower rates + ₹75K standard deduction, almost no other deductions.
Old: Higher rates but allows 80C, 80D, NPS, HRA, home loan deductions.
Rule of Thumb
Total deductions above ₹3.75 lakh? Old regime likely better. Below that? New regime wins.

📐 Methodology & Sources
All calculations use standard financial formulas. SIP returns use compound interest formula: FV = PMT × [((1+r)^n - 1) / r]. EMI uses: EMI = P × r × (1+r)^n / [(1+r)^n - 1]. Tax calculations follow Income Tax Act provisions for the current assessment year. Insurance premiums are indicative market averages.
