About EconKit
Smart tools for better money decisions.
What we do
EconKit provides free, high-quality business calculators that go beyond simple math. Every tool is built to deliver instant results paired with actionable insights — so you don't just get a number, you understand what it means and what to do next. From pricing strategies and profit margins to freelance rates and customer acquisition costs, our calculators cover the financial decisions that matter most to growing businesses.
Who it's for
We build for freelancers setting their rates for the first time, founders figuring out unit economics, and operators optimizing margins across their business. Whether you're a solo designer in Berlin, a SaaS founder in Lagos, or an e-commerce operator in Singapore, EconKit is designed to be useful wherever you are. Our tools work on any device, require no account, and respect your time by getting straight to the answer.
What makes us different
Most calculator sites give you a form and a number. We think that's only half the job. Every EconKit calculator includes context that helps you interpret your results: industry benchmarks so you can see where you stand, clear explanations of the formulas behind the math, and concrete next steps you can act on immediately.
There's no signup wall, no paywall for basic tools, and no dark patterns. We believe the best way to earn trust is to be genuinely useful — and that trust is the foundation everything else is built on.

Independence and accuracy
Every formula on EconKit is unit-tested. Every benchmark is sourced from publicly available data and reviewed regularly. The calculators exist to give you accurate numbers and honest context — not to push you toward a particular product or decision.
Where a tool or service is genuinely relevant to the decision you're making, we may include a clearly marked recommendation. These never influence calculator results or the advice on the page.
