How It Works: Integrating Tax Planning with Wealth Creation
Most Indian professionals treat income tax and investments as two separate mathematical problems. True financial independence requires integrating them. The Master Planner engine calculates your exact tax liability under the 2026 New Tax Regime guidelines, deduces your real liquid take-home pay, and immediately projects your wealth creation potential using the 50/30/20 budgeting rule.
The New Tax Regime Mathematics
Under the updated standard structures, the New Tax Regime offers a flat ₹50,000 standard deduction for salaried individuals. A Section 87A rebate makes taxable income up to ₹7,000,000 (effectively ₹7.5 Lakhs with the deduction) entirely tax-free. Our engine automatically checks this threshold before applying the 5% to 30% incremental tax slabs to your gross CTC.
The 20% Compounding Engine
By capturing 20% of your post-tax monthly income, the right-side dashboard uses the future value of an annuity due formula. Assuming a standard 12% annualized return (historically aligned with Indian broad-market index funds), the engine visualizes how systematic, automatic investment of your savings scales exponentially over 180 months (15 years).

Formula
Tax & Wealth Planning Framework: 1) Max 80C (₹1.5L), 2) NPS 80CCD(1B) (₹50K extra), 3) HRA exemption if applicable, 4) Choose regime saving more, 5) Invest tax saved into equity SIP.
Worked Example
Arjun saves ₹1.5L in ELSS (80C) + ₹50K NPS + ₹1.8L HRA = ₹3.8L deductions at 30% bracket = saves ₹1,26,840 in tax. Invest this ₹1.27L/year in SIP at 12% for 20 years = ₹1.23 crore extra corpus.
