What this calculator works out
Enter the pay rate you have agreed with a candidate, the days and hours they will work, and the margin you want to make. The calculator returns the weekly and hourly or daily charge rate you need to bill, including estimated employer National Insurance, holiday pay and pension contributions on the assumptions above.
It works from what you pay the candidate, not from what the candidate receives, so it does not calculate income tax, employee National Insurance or a personal net pay figure.
