Chartered Accountant & Financial Analysis Team
We started ArthCalculator to solve a problem we saw repeatedly: most online finance tools either give oversimplified estimates that miss crucial tax rules, or they exist merely to capture your phone number and sell you loans, credit cards, or mutual funds.
Every calculator on this platform is built and reviewed with input from qualified Chartered Accountants and finance specialists. We base our math directly on official Indian regulations:
- Income Tax Act: New vs Old Tax Regimes (Section 115BAC), Section 87A rebate and marginal relief, Chapter VI-A deductions (80C, 80D), and capital gains under Sections 111A and 112A for FY 2026-27.
- RBI Guidelines: Standard reducing-balance interest formulas and EMI amortization schedules used by Indian banks.
- Standard Investment Math: Transparent, standard formulas for SIP compounding, CAGR, XIRR, and discounted cash flows (DCF).
We operate with complete editorial independence. We do not sell financial products, we do not bias calculations to favor any bank or fund house, and we never ask you to register or share personal financial details.
