Make it yours
England, no loans or other income. Inside: assignment rate, no margin, levy or pension. Outside: £3,000 expenses, Personal Allowance salary, no pension or retained profit. Salary comparison: 5% employee and employer pension.
Revenue is day rate multiplied by billable days. The shared engine applies payroll taxes inside IR35 and company plus personal taxes outside IR35. Equivalent salary and rate solvers match cash, cash plus pension or economic value.
Important assumptions
Annual estimates, England by default, no other income or student loan. Illustrations use £3,000 company expenses, no opening reserves and a 12-month accounting period. Pension, gross benefits and retained profit are not spendable cash.
Frequently asked questions
Is revenue the same as take-home?
No. Employment costs, expenses and taxes can apply before money reaches you. Pension and retained profit are separate.
Can this decide IR35 status?
ContractorMoney.co.uk does not determine IR35 employment status. We model financial consequences after you select a status.
