What this calculator does

This calculator converts between annual salary, hourly rate, day rate, and target income. It accounts for working weeks per year, days per week, hours per day, and unpaid leave to give you accurate equivalent figures.

Who it is for

Contractors, freelancers, consultants, and anyone comparing permanent salaries with day rates or hourly rates.

How to use it

Select your conversion mode (e.g. salary to day rate), enter the relevant figure, and adjust your working pattern. The calculator instantly shows your equivalent rates across all time periods.

How the calculation works

Billable days = (days per week × weeks per year) − unpaid leave days. Day rate = annual amount ÷ billable days. Hourly rate = day rate ÷ hours per day. All conversions work in both directions.

Worked example

A £45,000 annual salary with 5 days/week and 46 working weeks (230 billable days): Day rate = £45,000 ÷ 230 = £195.65. Hourly rate (8-hour day) = £24.46.

Assumptions and limitations

  • Does not include tax calculations — use alongside the Take Home Pay or Contractor Calculator
  • Assumes consistent working pattern throughout the year
  • Standard assumption is 46 working weeks (52 minus 6 weeks holiday/bank holidays)
  • Does not account for sick days or training days

Frequently asked questions

What day rate is equivalent to a £50,000 salary?

Assuming 230 billable days (5 days/week, 46 weeks/year), a £50,000 salary is equivalent to a day rate of approximately £217. However, contractors typically charge more to cover lack of benefits, pension, and holiday pay.

How many billable days are there in a year?

A typical contractor works 220–230 billable days per year (46 weeks × 5 days = 230). This accounts for approximately 25 days holiday and 8 bank holidays.

Should my day rate be higher than the salary equivalent?

Yes, typically 20–50% higher. As a contractor you do not receive employer pension contributions, sick pay, holiday pay, training budgets, or other employee benefits.
