Chartered Accountant
ArthCalculator was founded with a singular purpose: to bridge the gap between complex financial mathematics and everyday decision-making. Most personal finance tools on the web are either simplistic estimates that hide critical nuances or sponsored marketing calculators designed to generate leads for financial products.
Every calculator on ArthCalculator is architected with strict financial engineering rigor—incorporating exact Indian Income Tax rules (CBDT circulars), RBI lending frameworks (reducing balance amortization), and institutional portfolio mathematics (CAGR, XIRR, Sharpe, Sortino, DCF).
