PAYE V umbrella Calculator- Excel

Hello

I am looking for someone to make me a 2 column comparison calculator. Ideally our candidates need to put in their day rate and the number of days they work in a month and the calculator will work out their take home pay. This must be based on UK tax system.

Column a needs to show all the deductions and final take home pay for the candidate under a PAYE programme assuming basic tax bracket.

Column b needs to show all the deductions and final take home pay for the candidate if they were to operate under an umbrella company

Must include reference to:
income tax, NI contributions, holiday pay at 12.09%, employers and employee NI and optional pension as the minimum requirement

Thanks and look forward to hearing back
