Core calculation
The main calculator begins with desired annual take-home income plus annual benefits and retirement funding. It gross-ups that owner-compensation goal using the effective tax estimate, adds annual operating costs, then divides by one minus the resilience margin. Finally, it divides required revenue by realistic billable capacity.
Annual billable hours = total weekly work hours × billable percentage × working weeks.
What the result does not claim
The calculator does not estimate a country-specific tax bill, prove a market rate, guarantee profit, replace a professional adviser, or decide what a client should pay. It provides a cost-and-capacity checkpoint for a wider pricing decision.
Privacy principle
The calculation runs in the browser. Inputs are stored locally on the same device for convenience and are not submitted to RatePilot. A shared link contains the values you choose to share in its URL, so review it before sending.
Editorial standard
Guidance is written specifically for freelance pricing decisions, separates examples from guarantees, and avoids invented market benchmarks. Pages are updated when the calculation or material guidance changes—not simply to display a newer date.
