Quick answer
Set target income/expenses/tax, then divide by the hours you can actually bill each year. International rates must account for FX/payment fees/tax/time zones.
Why it matters
The denominator is billable hours, not 40 hours x 52 weeks.
Add a buffer for FX swings.
Step by step
- Set a target annual income (keep pre/post-tax consistent).
- Add business costs/tax/insurance/gaps/margin.
- Calculate real billable hours per year, then divide to get the floor hourly rate.
- Calibrate with market/peer/closed-deal data; don't reverse-engineer a low price.
- State scope/payment/revision limits/rush fees in the quote.
Common mistakes
- Assuming 40 hours x 52 weeks are billable.
- Omitting tax/software/insurance/gaps/bad debt.
- Copying a competitor's low price without covering costs.
- Letting scope creep go unpaid.
Checklist
- Target income/costs/tax/margin confirmed.
- Billable hours reduced for gaps/admin/sales.
- Hourly/day/project rates use consistent assumptions.
- Market rate cross-checked.
- Quote includes scope/payment/revisions/rush terms.
Key facts
- Add a buffer for FX swings.
- W-8BEN/VAT depends on location.
