400 day rate × 4 days/week × 6 unbilled weeks: 9,600 income loss. Freelancers averaging 40-45 billable weeks vs 50 working is common. Buffer for this in hourly rate — builds cushion for holidays, sick, admin, client gaps.
Quick example
With day rate of 400 and billable days per week of 4 (plus unbilled weeks per year of 6), the result is 9,600.00. Change any figure and watch the output shift — it's often more useful to see the pattern than to memorise the formula.
Which inputs matter most
You enter Day Rate, Billable Days per Week, and Unbilled Weeks per Year. Not every input has equal weight. Flip one at a time toward extreme values to feel which ones move the needle most for your situation.
What's happening under the hood
Lost revenue = rate × potential days missed. The formula is listed in full below. If the number looks off, you can retrace the calculation by hand — that's the point of showing the working.
Using this in discovery calls
Knowing the number behind your rate gives you confidence in quoting it. Clients can sense rate doubt; they can also sense rate certainty. This tool helps build the latter.
What this doesn't capture
Freelance income is lumpy. The calculation assumes steady work; reality includes dry spells, delayed invoices, and client churn. Plan against a pessimistic version of the result, not the central case.
Where to go next
This calculation rarely sits alone in a planning exercise. If you're running these numbers, you'll probably also want the freelance late payment cost calculator, the freelance tools cost calculator, and the freelance underpricing calculator — each one answers a different question in the same territory. Treating them as a set rather than in isolation usually produces a more honest picture.
Freelance vacancy impact produces a loss figure based on the inputs provided.
