How much can you really earn as a contractor?
Earnings by Role
Day rates vary by sector, experience, and demand. Here's the reality.
Day rate ranges by sector (2026/27)
IT/DevOps: £350–800/day depending on specialism and seniority.
Finance/data: £400–700.
Project management/change: £300–600.
UX/design: £400–750.
Operations/programme: £350–950.
Your specialism determines your ceiling; generic positioning keeps you near the floor.
Why headline rate is not take-home
Day rate ÷ 220 days = misleading figure.
Real billing days: 170–185 accounting for bench (20–30 days), holiday (20 days unpaid), admin/training (5–10 days).
Further reduced by 25–35% effective tax on extraction.
So £500/day on 176 billing days = £88,000 revenue becomes ~£40–50k net after all deductions.
Billing days reality
220 working days per year baseline.
Less 20 days annual leave (unpaid).
Less 20–30 days average bench time per year.
Less 5–10 days admin/training/professional development.
Realistic billing: 170–185 days. Plan for this, not 220.
What your rate must cover
Corporation tax (~19% of profit). Personal income tax + NI. Accountancy (£1,500–2,500/year). Insurance (£200–600). Equipment/software (£1,000–3,000). Pension funding (should be 8–12% of revenue; most contractors underfund). Emergency fund/buffer (3–6 months).
The effective rate calculation
Total annual revenue ÷ actual billed days = effective rate.
Reveals reality vs headline.
£500/day headline on 176 actual billing days = £88,000 revenue, effective rate £500.
But if you only actually bill 160 days, your effective rate drops to £550 (higher!) per billing day to reach same annual income.
