The formula
- Billable % = billable hours ÷ total hours worked × 100
- Weekly value = billable hours × bill rate
- Annualised value = weekly value × 48 working weeks
What counts as billable
Billable hours are the hours you can invoice a client against an agreed engagement — design, development, consulting, review calls that the contract covers. Internal standups, proposals, hiring and admin are real work, but they are non-billable: the business absorbs their cost.
Most services teams guess this split. The honest number usually lands lower than the guess, because small unbilled tasks — a ten-minute fix, an untracked call — never reach the timesheet. That is exactly the leak this calculator prices: at ₹1,500 an hour, two forgotten hours a week is over ₹1.4 lakh per person per year.
What a healthy billable percentage looks like
Agencies and IT services firms typically target 60–80% billable time for delivery roles. Below that, projects are absorbing too much overhead per billed hour; at 100%, nobody is left to improve anything internally. Track the trend rather than chasing a single week — a falling billable share with a steady workload is the earliest sign of scope creep or unpriced support.
Stop calculating this by hand
Workclave records billable vs non-billable automatically because every session is linked to a project the moment it starts — the split this calculator estimates becomes a report you open, not a guess.
Billable hours calculator — common questions
Should meetings count as billable hours?
If the engagement covers them — sprint reviews, client workshops — yes, bill them. Internal meetings about the client that the contract does not cover are non-billable delivery cost. The distinction should be written into the statement of work, not decided at invoice time.
Why 48 weeks and not 52?
Leave, public holidays and gaps between engagements consume roughly four weeks for most Indian services teams. Using 48 keeps the annual figure honest. Change your weekly numbers if your team runs a different calendar.
How do I raise the billable percentage without overworking people?
The biggest gains come from capturing work that already happens — recording sessions as they run rather than reconstructing the week on Friday — and from moving recurring internal load (reporting, status decks) off delivery staff. Working more hours raises value but not the percentage.
