Day Rate Explained
The daily fee a contractor charges for their services. Converting between day rates and equivalent annual salaries helps you compare contractor and permanent roles.
What is Day Rate?
A day rate is the daily fee a contractor or freelancer charges a client. Unlike a salaried employee who receives a fixed monthly payment, contractors invoice for the days they actually work. Day rates vary hugely by industry, experience and location. IT contractors in London might charge £500-800 per day, while trades contractors might charge £150-300.
How it works
To convert a day rate to an annual salary equivalent, multiply by the number of working days per year. Most calculations use 220 days (52 weeks minus 25 days holiday minus 8 bank holidays = 219, rounded to 220). A £400/day rate equals roughly £88,000 annual equivalent. However, contractors do not receive employee benefits (pension, sick pay, holiday pay), so the true comparison salary is lower. A common rule of thumb is that a contractor needs to earn 30-50% more than the equivalent salary to account for gaps between contracts, lack of benefits and additional admin costs.
Real example
Anna is offered a permanent role at £65,000 or a contract at £450/day. The contract annual equivalent is £99,000 (£450 x 220). After accounting for 4 weeks unpaid holiday, employer pension equivalent and sick pay, the adjusted comparison is around £78,000. The contract still pays more, but the gap narrows once you factor in insurance costs and accountant fees for running a limited company.
Who does this affect?
Contractors, freelancers and interim professionals across all industries. Day rates are standard in IT, consulting, engineering, finance, creative services and construction. Understanding the salary equivalent helps you negotiate rates and compare opportunities.
