Free business calculators
Free calculators for freelance rates, pricing, and business decisions.
RateClarity is a small set of practical tools for freelancers, consultants, and service businesses. The calculators are free, they run in your browser, and they do not require an account. Results are planning estimates based on the figures you enter — not a promise about what the market will pay.

Why RateClarity
The calculators are meant to be inspectable. You bring the figures; the site shows the arithmetic.
Transparent calculations
Each tool shows the inputs it uses and explains how the result is produced. The formula is not hidden behind a pitch.
Visible assumptions
Tax fields are allowances. Utilization, unpaid time, and buffers are explicit. You can see what the number depends on.
Free to use
The calculators are free. There is no account, trial, or paywall in front of the result.
Built for planning
Use the result to set a rate, quote a project, or check whether a client still pays. These are planning estimates, not professional advice.

Guides
Short explanations that sit beside the calculators: how to set a rate, choose a pricing model, and read whether a client still pays.

Hourly and day rates sell different units of time. See how they differ, when a day rate fits, and why unpaid time inside a billed day matters.

- What Is an Effective Hourly Rate?
Effective hourly rate is what you earn after unpaid revisions, sales, and admin. See how it differs from a quoted rate and from profit.
