OwnerMath

Project Profitability Calculator

See whether a project actually made money after costs, unpaid time, overhead, and payment fees.

A project can pay well on paper and still be a bad deal once your time, costs, and margin are dragged into the light.

Revenue is not profit

Collected invoices are top-line revenue. Profit is what survives after direct costs, subcontractors, tools, payment fees, and overhead allocation. If you only track revenue, you are measuring motion, not margin.

Owner time still costs something

Your time is not free just because no invoice line item says “founder labor.” This calculator includes your hours so an "easy" project does not fake profitability by hiding labor in the shadows.

When to stop selling a service package

If multiple deliveries show weak margins, constant scope friction, and effective rates below your baseline, stop treating it as a temporary blip. Reprice the package, tighten scope boundaries, or retire it.
