Direct answer

A defensible freelance-rate plan starts with the annual revenue the business must generate, then divides that revenue by realistic billable hours. It should not divide a desired salary by every hour in the year, because freelancers normally fund business costs, unpaid time and their own tax or social-contribution reserve.

The calculation sequence

Pre-reserve owner income = take-home target รท (1 โˆ’ reserve rate)
Required revenue = (pre-reserve owner income + business costs) รท (1 โˆ’ contingency margin)
Billable hours = working weeks ร— days per week ร— hours per day ร— billable utilisation
Hourly rate = required revenue รท billable hours

The reserve and margin must each remain below 100%. The reserve is a planning allowance, not a statutory tax calculation. The margin is treated as a share of final revenue, which is why the model divides by one minus the margin rate.

Example

Assume a 40,000 personal take-home target, a 25% reserve, 10,000 of annual business costs, a 10% contingency margin, 46 working weeks, five days per week, 7.5 hours per day and 70% billable utilisation.

Billable-utilisation sensitivity

Utilisation is one of the most influential assumptions because the annual revenue target is spread across fewer or more chargeable hours.

70%1,207.558.28437.08
80%1,380.050.99382.45

A lower utilisation assumption is more conservative. It recognises that not every working hour can be invoiced.

Business costs to consider

Travel, workspace and deliveryTransport, coworking, postage, subcontractorsDo not assume every cost can be passed directly to clients

Gross salary is not freelance revenue

An employee salary is normally only one component of the employerโ€™s total cost and is not the same as personal take-home pay. Freelance revenue may need to cover unpaid leave, sickness, pension provision, insurance, equipment, professional costs and periods without client work. A linked salary calculator can provide context, but it should not automatically become the take-home target.

Limitations

  • The model does not calculate income tax, social contributions, VAT/GST or corporation tax.
  • It does not determine whether an expense is deductible.
  • It assumes the same revenue requirement across the year and does not model seasonal cash flow.
  • It does not price intellectual property, rush work, scope risk, usage rights or client concentration.
  • The result is a planning floor, not a guarantee that the market will accept the rate.
