Frequently Asked Questions
What is EconKit?
EconKit is a free platform of 40+ business calculators and decision tools — pricing, profit margins, freelance rates, SaaS metrics, e-commerce economics, and more. Every formula is unit-tested and every result comes with benchmark data and actionable insights so you can make confident money decisions without signing up for anything.
Are EconKit's calculators accurate?
Yes. All calculator logic lives in pure TypeScript functions with 400+ unit tests covering edge cases, currency formatting, and regression scenarios. We prefer tested formulas to AI-generated estimates, and every benchmark is sourced from aggregated industry data rather than pulled from a model.
Do I need to sign up or pay?
No. Every calculator is free, works instantly in the browser, and requires no account. We monetize through optional, contextual affiliate recommendations on the results page — not paywalls, signups, or ads that slow the page down.
Do these calculators work for non-US businesses?
Yes. EconKit is built to be globally useful: currencies are user-selectable via a header switcher, percentages and ratios are math-only (currency-agnostic), and we avoid US-only tax assumptions in the core formulas. Freelance-tax and employment cost calculators flag country-specific assumptions clearly.
Can I share or save my calculations?
Yes. Every calculator encodes its full input state in the URL, so you can copy the page URL after running the numbers and share the exact scenario with a client, team, or future-you. You can also print the page — calculator layouts are designed to render cleanly for PDFs and meeting handouts.
