What does each client really pay per hour?
Enter what each client paid in a month and the hours your team spent on them. You'll see the effective hourly rate per client, how it compares with your target rate and what the extra hours would have been worth. Runs in your browser — nothing is stored.
Pre-filled values are a fictional example — replace them with your own numbers. "Unpaid time" estimates what extra hours would be worth at your target rate; it is not lost cash.
How the calculator works
Effective rate
Revenue ÷ hours spent. Example: €2,400 ÷ 52 h = €46.15 per hour.
vs target
(Effective rate − target rate) ÷ target rate × 100. Below zero means the client pays less than your target.
Hours the fee covers
Revenue ÷ target rate: how many hours the client pays for at your target rate.
Unpaid time
Hours × target rate − revenue, counted only for clients below target.
Your effective rate is only as accurate as your time logs.
If hours per client are reconstructed on Friday afternoon, the effective rate is a guess. With opiq TEAM, your team logs work per client with one click as they go — timer, "My day" or a manual entry — and you see hours per client, team and employee, plus profitability by client.

Effective hourly rate questions
What is an effective hourly rate?
Your effective hourly rate for a client is what the client actually paid you divided by the hours your team really spent on their work: revenue ÷ hours. It turns a fixed fee, retainer or project price into an hourly number you can compare with your target rate.
Why is it lower than my billable rate?
Fixed fees and retainers don't grow when work takes longer. Extra revisions, calls, emails and scope creep add hours but not revenue, so the effective rate drops. Hourly clients can drop too if some hours are written off or never invoiced.
What target rate should I use?
Use the rate you need to cover salaries, overhead and your profit margin — often your standard hourly rate. Compare every client against the same target so you can see which ones pay well and which ones quietly cost you money.
What does "unpaid time at target" mean?
For each client below target: hours × target rate − revenue. It is what the extra hours would have been worth at your target rate — a signal to reprice, renegotiate scope or work more efficiently. It is an estimate, not lost cash.
Where do I get hours per client?
From work logs. With opiq TEAM, employees log work per client with one click (timer, "My day" or a manual entry), so you see hours and profitability per client without spreadsheets — and without screen recording or keystroke tracking.
