| From: | To: |
The Salary to Contract Rate Calculator converts an annual salary into an equivalent daily contract rate for UK contractors, accounting for 220 working days per year and including a 20% margin to cover business costs, benefits, and risk.
The calculator uses the contract rate formula:
Where:
Explanation: The formula divides the annual salary by 220 working days to get the base daily rate, then adds a 20% margin to account for business expenses, benefits, and contractor risk.
Details: Accurate contract rate calculation ensures contractors are fairly compensated compared to permanent employees, covering costs like pensions, holidays, sick pay, and business expenses that permanent employees receive as benefits.
Tips: Enter your current or desired annual salary in GBP. The calculator will automatically compute the equivalent daily contract rate including the 20% margin.
Q1: Why 220 working days?
A: 220 days accounts for weekends, bank holidays, and typical annual leave, providing a realistic number of billable days per year.
Q2: Why include a 20% margin?
A: The 20% margin covers business costs, benefits (pension, holiday pay), insurance, and the additional risk contractors assume compared to permanent employees.
Q3: Is this calculation specific to the UK?
A: Yes, this calculation uses UK standards for working days and typical contractor margins. Other countries may have different working day counts and margin expectations.
Q4: Can I adjust the margin percentage?
A: This calculator uses a standard 20% margin. For different margin requirements, you would need to manually adjust the calculation.
Q5: What if I work more or fewer than 220 days?
A: The 220-day standard is an industry average. If your working pattern differs significantly, you may need to adjust the calculation accordingly.
