How this is worked out
The annual figure multiplies the day rate by 220 billable days. That is an assumption, not an official figure: a full year has 260 weekdays, and contractors lose days to holidays, bank holidays and gaps between contracts. Scale the result to your own days.
Take-home treats the whole amount as PAYE salary, as an umbrella company or an inside IR35 engagement would pay it. Umbrella fees, employer NI and pension deductions are not included.
Assumptions: England, 2026-27 rates, tax code 1257L, no other income.
