Step-by-Step Calculation
Estimate annual billable hours
Multiply planned working weeks by weekly hours, then keep only the portion expected to be billable.
billableHoursPerYear = W * H * (U / 100)
Add the benefits allowance
Increase the personal income target by the chosen allowance for employee-style benefits.
incomeWithBenefits = I * (1 + B / 100)
Add annual overheads
Add the annual cost of running the freelance accounting business.
revenueBeforeBuffer = incomeWithBenefits + O
Apply the buffer
Increase the revenue requirement by the profit and contingency percentage.
targetAnnualRevenue = revenueBeforeBuffer * (1 + P / 100)
Calculate the hourly rate
Divide the annual revenue target by annual billable capacity.
recommendedHourlyRate = targetAnnualRevenue / billableHoursPerYear
Example: independent accountant with a $75,000 income target
Calculate annual billable hours
46 * 40 * (70 / 100)
1,288 hours
Add benefits allowance
75000 * (1 + 15 / 100)
$86,250
Add business overheads
86250 + 15000
$101,250
Apply profit and contingency buffer
101250 * (1 + 10 / 100)
$111,375
Calculate hourly rate
111375 / 1288
$86.47 per hour

Common Mistakes to Avoid
Using all working hours as billable hours and overlooking administration or business development.
Leaving out insurance, software subscriptions, memberships or equipment replacement costs.
Treating unpaid leave and pension contributions as personal spending rather than business funding needs.
Applying the buffer only to overheads instead of the full revenue requirement.
Using an annual income target that already includes costs entered separately as overheads.
