Net pay for a personal trainer with £55,000 of turnover

A personal trainer operating as a sole trader with £55,000 of turnover for 2026/27 has taxable profits of £52,250 after the actual business expenses. Income tax on those profits comes to £8,332; Class 4 NI (6% / 2%) comes to £2,302; and the voluntary Class 2 contribution at £179.40 buys a State Pension qualifying year on top.

Net cash after tax + NI: £41,437. Effective rate on turnover: 19.7%. Marginal rate on the next £1 of trading profit: 42%.

The recurring "should I incorporate?" question: at this turnover, a Ltd Co (no pension, same expense pot) would deliver £41,103 net — £334 less than the sole-trader route. There is no clean intersection in the £15k–£400k range examined — one route dominates throughout.

Why this scenario is different

Compared to the closest peer profile — Freelance photographer at £55,000 — this scenario sits £0 higher on gross income. That moves net cash by +£0, the pension contribution by +£0, and the effective rate by +0%. The effective rate moves only modestly — both scenarios sit inside the same binding tax band. Taxable profits change from £52,250 to £52,250 (after the trading-allowance / actual-expenses choice).

Questions this scenario raises

Where does the BracketMath engine source its rates?

Income tax / NI / CT / dividend rates come from HMRC's published 2026/27 rate tables (gov.uk/government/publications/rates-and-allowances-income-tax). Pension rules come from FA 2004 and the FCA's consumer guidance. Historical investment returns used in the Monte Carlo engine come from a 125-year UK gilt + UK equity series stored in src/data/historical-returns.json. Every constant carries a source URL in the source code.

Why do some columns of the table use cash and others use net wealth?

Net cash is the £ that arrive in your bank account. Net wealth includes pension contributions valued at face (£1 of pension = £1 of wealth, since it will eventually be spent — possibly at a lower marginal rate than today). The optimiser uses a `pensionWeight` parameter so the user can adjust the weight; this page sets it according to the row's `pensionPref` (0 / 0.5 / 1.0 for none / modest / aggressive).

Is the figure on this page net of accountancy fees?

Yes when relevant — the take-home calculator deducts an umbrella fee for inside-IR35 rows (£1,500/yr assumed) and the optimiser allows for an arbitrary annual business expense pot (£3,500/yr default for Ltd Co rows). Sole-trader rows assume the higher of £800/yr or 5% of turnover as actual business expenses, which approximates a low-overhead service business.

What tax year do these figures use?

2026/27 UK tax year (6 April 2026 – 5 April 2027), England, Wales and Northern Ireland rates. Scottish tax bands are not modelled in this calculation — Scotland has a separate Starter / Basic / Intermediate / Higher / Advanced / Top band schedule that will be added in a future batch.

What is the Personal Allowance and how is it used in this calculation?

The Personal Allowance is the first £12,570 of non-savings, non-dividend income on which no income tax is charged. It is consumed from the bottom up: salary first, then dividends. Above £100,000 of adjusted net income the allowance tapers at £1 lost for every £2 of income, fully eroded at £125,140 — producing the well-known 60% effective marginal rate inside that £25,140-wide band.

Methodology

Income tax, National Insurance and Corporation Tax bands taken from HMRC's 2026/27 rates and allowances tables (gov.uk/.../income-tax; corporation-tax). Pension Annual Allowance and taper rules from Finance Act 2004 / 2023. Trading allowance per ITTOIA 2005 s.783A. Voluntary Class 2 figure (£179.40/yr = £3.45/wk × 52) from HMRC voluntary NI guidance.

Style: 2026/27 tax year throughout; figures rounded to whole pounds in the user-facing prose; effective rates computed as (deductions / gross). The voice is methodological — no first person, no claimed credentials, no marketing fluff.
