1. Indian Income Tax Calculator (Budget 2024 / FY 2025–26 & FY 2026–27)
The Union Budget revised the New Tax Regime under Section 115BAC of the Income Tax Act, 1961. Our tax simulation engine calculates exact liability across both Old and New regimes, factoring in the increased Standard Deduction of ₹75,000 for salaried taxpayers, Section 87A marginal tax rebate (tax-free threshold up to ₹7,75,000), and comprehensive Chapter VI-A deductions (Section 80C, 80D, 80CCD(1B) for NPS, and Section 24(b) for Home Loan interest).

2. Home Loan EMI & Prepayment Acceleration Mathematical Models
Equated Monthly Installment (EMI) calculations utilize the standard actuarial amortization formula:
E = P × r × (1 + r)n / ((1 + r)n - 1)
Where P represents principal loan sanction, r is the monthly periodic interest rate (Annual Rate / 12 / 100), and n represents duration in months. Our proprietary Prepayment Hack Engine demonstrates how adding 1 extra EMI annually or applying an annual 5% EMI step-up saves an average of ₹18 to ₹25 Lakhs in compound interest on typical 20-year Indian home loans.
3. Mutual Fund Systematic Investment Plan (SIP) & Wealth Compounding
Wealth accumulation via equity mutual funds is calculated utilizing monthly compounding future value principles:
FV = P × [((1 + i)n - 1) / i] × (1 + i)
Where P is monthly investment, i is monthly rate of return, and n is number of monthly installments. The suite covers Flat SIP, Step-Up SIP (annual percentage or fixed step-up), Systematic Withdrawal Plans (SWP) for retirement income, and lumpsum compound interest.
