Contractor Calculators

Our Inside IR35, Outside IR35 and PAYE calculators allow you to compare multiple working arrangements. From being caught by the IR35 legislation and working through an umbrella company, to being outside IR35 working through a limited company.

Accurate

Our calculators were built by an ACA qualified accountant using precise methodologies prescribed by HMRC. They are kept up to date with any changes to tax rates.

Flexible

Unlike other umbrella company calculators, ours does not make estimates. Detailed inputs provide the ability to precisely calculate taxes, take home pay and total capital received.

Easy to Understand

The breakdown of take home pay and taxes owed can be viewed as tables or easy-to-follow graphs, simplifying what other calculators make very complex.
