Contract adverts quote “outside IR35 day rates” while employers quote annual salaries. Translating between them without a net-first lens invites bad deals. Start from the money that actually clears your current account.

IR35 and outside rates

Clients quoting outside IR35 day rates expect you to carry employer-NI-equivalent risk, pension, and leave. Inside-IR35 engagements behave more like PAYE—this model is tuned to self-employed profit paths; validate status with your advisor.

VAT and expenses

VAT-registered contractors quote ex-VAT fees; expenses reduce taxable profit before NI and income tax. Keep your model aligned with how your accountant recognises profit.

VAT and expenses sit outside PAYE thinking

Registered businesses may add VAT on top of fees; travellers reclaim legitimate expenses before profit. Keep your model aligned with how your accountant recognizes profit—not every contractor expense matches day-rate psychology.

Volatile months mean runway matters

A higher headline rate buys cushion when clients delay payment or projects slip. Net parity is necessary, not sufficient, for financial comfort.

How we calculate your break-even rate

We solve required turnover from your PAYE net target, then add income tax, NI, student loan, pension, and sole trader costs, divided by billable days.

Default path: 220 days − 25 holiday − 10 sick/admin → 185 gross; at 85%~157 billable days. If IR35-inside months appear, cut billable days again—your day rate must rise mechanically.

Ignore 100% utilisation myths: 20–30% of the year is sales, CPD, and gaps.

Typical UK day rates by industry (2025/2026)

Outside IR35 B2B bands; London premiums often +15–30%.

Industry Junior (0-3y) Mid (3-7y) Senior (7+y)
Software development £350-500 £500-800 £800-1,400
Design / UX £300-450 £450-700 £700-1,100
Management consulting £450-700 £700-1,200 £1,200-2,500

Finance / accounting £350-550 £550-900 £900-1,400

Quote **VAT on top** when registered; keep parity math in **net-of-VAT** profit.

What to say when clients push back on your rate

Employer NI at 13.8% is the hidden comparator—your day rate replaces loaded payroll, not Glassdoor gross.

Script: “My rate covers Class 2/4, no employer pension, and pipeline risk. If budget is capped, we cut deliverables or phases—not quality in silence.”

Day vs hour: use day for discovery-heavy work; hourly with a weekly floor.

VAT: proposals exclusive; add VAT on invoice when registered.

Indicative ranges from market surveys — verify with your own research.

UK freelance rates are typically quoted as day rates. London and the South East command 15–25% higher rates than other regions. The average UK freelance day rate across all disciplines was £390 in 2025 (YunoJuno, 62,000+ bookings). Remember to account for IR35 status — if you're inside IR35, your effective take-home is significantly lower. The calculator above helps you model PAYE vs sole trader net. Hourly figures in parentheses assume an 8-hour day for rough comparison only.

FAQ

How do I convert £70k salary to a day rate?

Start from net you need, add tax + NI + pension + costs, divide by ~140–185 billable days—use the tool instead of £70k ÷ 220.

Should I include employer NI in negotiations?

Yes—procurement compares loaded cost; explaining employer NI (~13.8%) and pension helps defend higher day rates.

What about student loans?

Include your plan in inputs—the calculator models Plan-style withholdings in the teaching path.
