Day Rate to Salary Calculator
Multiply a day rate by the working days you actually expect to bill.
Day rate as an employed salary
Contractors quote day rates; employees think in salaries. Multiplying a day rate by a notional working year gives a rough equivalent — but employees also receive holiday pay, employer pension contributions and more predictable hours. Contractors fund gaps, accountancy and benefits themselves, so a headline day rate that ‘matches’ salary can still leave you behind. Use this calculator for ballpark comparisons when moving between permanent and contract roles. Reverse the view with salary to day rate and sense-check freelance floors with freelancer minimum rate. Effective hours matter via effective hourly wage. Not tax or IR35 advice. Interview processes sometimes ask for a salary expectation while you still think in day rates — convert both ways and write the numbers down before the call. Notice periods, garden leave and non-compete clauses on the permanent side have no day-rate twin; weigh them qualitatively. If a contract role includes equipment or travel stipends, subtract those costs from the permanent package before declaring a winner.
Worked example
A £450 day rate × 220 days = £99,000 headline equivalent. After realistic utilisation of 190 days you are nearer £85,500 before accountancy, insurance and unpaid admin. A permanent role at £75,000 plus pension match and holiday may compete once those costs and gaps are honest. Inside IR35 umbrella take-home needs a separate calculator with an accountant.
Limits and assumptions
Ignores tax wrappers, umbrella margins and regional NI differences. Utilisation rarely stays at optimistic levels year-round. Not a contract review or employment status determination.
Frequently asked questions
How many days should I multiply by?
Common planning figures sit around 220 working days after weekends and holiday. Adjust for your industry’s norms.
Does the salary equivalent include benefits?
The raw multiplication does not. Mentally value pension, holiday and sick pay when you compare offers.
Is a higher day rate always better than salary?
Not if utilisation is low or you fund your own benefits. Compare effective annual income after gaps.
Should VAT be in the day rate?
State clearly whether quotes are ex-VAT. Salary comparisons usually think in gross pay before VAT concepts.
How do I treat half-days?
Convert to a consistent day-equivalent (two half-days = one day) before annualising.
