Freelance Annual Review Calculator

An end-of-year freelance review surfaces what worked and what to adjust. This calculator takes total revenue, total expenses, billable hours, client count, and working weeks to compute net profit, profit margin, effective profit per billable hour, revenue per client, and weekly billable hours. The output is most useful as a year-over-year comparison rather than an absolute benchmark.

The five secondary metrics each tell a different story. Profit margin reads expense efficiency. Effective profit per hour reads pricing power against the time actually billed. Revenue per client reads concentration and average deal size. Weekly billable hours reads capacity utilisation against working weeks. Together they identify which lever is most worth pulling in the next year.

Quick example

With total revenue 80,000, total expenses 15,000, billable hours 1,100, client count 8, and working weeks 48, the result is 65,000 in net profit. The margin works out to 81.25%; effective profit per billable hour to about 59 in local currency; revenue per client to 10,000; weekly billable hours to 22.9. All currency figures are shown in whichever currency the calculator is set to.

Which inputs matter most

The inputs are Total Revenue, Total Expenses, Billable Hours, Client Count, and Working Weeks. Revenue and expenses drive the headline profit and margin together; billable hours and working weeks drive the time-based metrics (effective profit per hour, weekly billable hours); client count drives concentration. A meaningful change in any single input usually shifts only one or two of the five output metrics — which makes the tool useful for isolating where last year's gains or losses actually came from.

What's happening under the hood

Net profit equals revenue minus expenses. Profit margin equals net profit divided by revenue (expressed as a percentage). Effective profit per hour equals net profit divided by billable hours — the take-home value of each billable hour after expenses. Revenue per client equals total revenue divided by client count. Weekly billable hours equals total billable hours divided by working weeks. The full formula sits in the panel below.

Reading the secondary metrics

Profit margin reflects expense efficiency relative to revenue — lower margins suggest a heavier expense load, though the absolute level varies by profession and tooling. Effective profit per hour shows the take-home value of each billable hour after expenses, which is the figure most directly comparable to a salaried hourly equivalent. Revenue per client highlights concentration risk and pricing — a small number of high-paying clients carries different risk than many smaller ones at the same revenue total. Weekly billable hours surfaces realistic capacity against working weeks.

What this calculation does not capture

Income tax, self-employment tax (where applicable), retirement contributions that reduce taxable income, unbilled time spent on admin and business development, deferred revenue collected after year-end, bad debt write-offs, and the time cost of professional development all sit outside this calculation. The output is a recurring-cost-and-revenue snapshot rather than a full tax-adjusted income picture. The year-over-year delta in each metric is typically more informative than the absolute figure in any single year.
