The Argument About Profit Per Hour Is Always the Denominator

Count the hours you would rather not

The hours that disappear from these calculations are always the same ones: preparing a quotation that was not accepted, the second and third emails asking for payment, the meeting that could have been a message, and the work redone because the brief moved. They are unbilled, so they feel like they should not count, and they are precisely the hours a business can reduce. Measuring them is the only way to notice that a client paying a good rate on paper is a poor one in practice — the useful comparison is profit per hour by client, and it usually reorders the list in a way the invoice totals do not.

Profit, not revenue, and after paying yourself

The numerator has to be profit after every cost, and for an owner-operated business that includes a market salary for the owner's own time. Skipping that step produces a figure that looks like profit and is actually wages, which is how a business can appear profitable for years while paying its founder less than an employee would accept. Once a proper salary is deducted, profit per hour measures what the business earns beyond the labour it consumes — and a number near zero, or below it, is the honest signal that the enterprise is a job with extra paperwork rather than a going concern.

Frequently asked questions

How should shared costs be split across hours?

By the hours that actually consume them, which usually means all worked hours rather than only billable ones. Rent, software and insurance are incurred whether or not a given hour was invoiced, so allocating them across billable hours alone concentrates the whole overhead into a subset and makes those hours look expensive while the rest look free. Spreading them across every worked hour gives a truer cost per hour and a truer sense of how much unbilled time a business can absorb before its overheads stop being covered.

Does raising prices always raise profit per hour?

Usually, and often by more than the price rise, because a higher price does not increase the hours worked. Ten per cent added to a rate flows almost entirely into profit if the same clients accept it, which is why price is the strongest lever available to a small business and the one most often left untouched. The exception is when a higher price attracts clients who expect more attention: if a 10 % rise brings 20 % more meetings and revisions, the hours grow faster than the money and the figure falls. Tracking profit per hour before and after a rise is the only way to tell which happened.
