Financial calculators built for the way Indians think about money

Understanding your own money should not require a spreadsheet or a chartered accountant. Eternexa brings together the everyday calculators salaried Indians need — a take-home salary calculator that turns your CTC into real in-hand pay, an income-tax calculator that compares the old and new regimes side by side, a SIP calculator to project your investments, and an EMI calculator with a prepayment planner.

Every tool is free, needs no sign-up, and calculates in your browser. For saveable and shareable results, the numbers you enter appear in the page URL; see our privacy policy before sharing a link. Results use the familiar Indian format — Lakh and Crore — and show how each figure is calculated. Rule-based estimates use our published FY 2026-27 assumptions.
