What this leaves out or assumes
- Before tax, and before any fees, expenses or pension. An employee's salary also pays for holidays and sick days, so a day rate and a salary are not like for like.
Where the figures come from
This sum uses only the numbers you entered.
How many working days are there in a year?
Count Monday to Friday, then take off the bank holidays that fall on them. In 2027, England and Wales have 253 such days. Then take off your own holiday and any other days you will not work. The calculator uses GOV.UK's own list of bank holidays, so it counts the real days for the year you choose.
Day rates and salaries are not like for like
A contractor's day rate pays only for the days worked. An employee's salary also pays for holidays, bank holidays and sick days, and the employer pays National Insurance and pension on top. So the same yearly figure is not the same deal. This calculator gives the arithmetic before tax and costs; the take-home pay calculator shows tax on a salary.
