An honest umbrella company take-home calculator for 2026/27. Every deduction shown, nothing gated, no email wall — compare umbrella margins side by side and see exactly what lands in your account.
When you work through an umbrella company on an inside-IR35 contract, the rate your agency pays — the assignment rate — is not your salary. The umbrella deducts its margin and all employment costs from that rate before your gross pay exists. This calculator solves for your real gross pay, then applies PAYE income tax, National Insurance, student loan and pension exactly as your payslip would.
The gap between rate and reality is normal — it's the employment costs above plus your own tax and NI, not the umbrella overcharging. Differences between compliant umbrellas should come down to margin alone, which is exactly what the comparison tool isolates.
From 6 April 2026, joint & several liability (JSL) makes agencies and end clients liable for unpaid PAYE in the umbrella supply chain. Only ever use an FCSA- or SafeRec-certified provider. Figures here are annualised estimates for guidance; your payslip is calculated per pay period and may differ slightly.
