Self-employed or employed: which leaves you better off?
There's no one right answer - it depends on your hours, your rate and how much ownership you want to take. Move the sliders and see the whole picture: take-home pay, pension, holidays and the trade-offs.
The headline
Estimated yearly take-home after tax, National Insurance and pension contributions.
Employed
Paid 52 weeks, including 5.6 weeks' holiday.
Beyond the numbers
The trade-offs.
Money is only half the decision. Self-employment means taking ownership of things an employer would handle - and that ownership is exactly where the higher take-home comes from.
What you take on, self-employed
- No sick pay. If you can't work, you don't earn. Employees get Statutory Sick Pay.
- Unpaid holidays. Every week off comes out of your income - the sliders above price that in.
- Your own pension. Nobody enrols you and nobody tops it up. The 3% an employer would add is yours to replace, or lose.
- Your own admin. A Self Assessment tax return each year, your own insurance, and setting money aside for the tax bill.
- Finding the work. Quiet weeks are your problem - unless someone fills your diary for you, which is the part we do.
What you gain, self-employed
- A higher rate for the same hour. The gap between £20 and an employed £12.90 is what funds the responsibilities on the left - and usually more than covers them.
- Your diary is yours. School hours, term-time only, no evenings - you decide, nobody approves it.
- Your clients are yours. You're building something you own, and it grows with your reputation.
- Expenses reduce your tax. Travel, products and insurance come off your profit before tax is worked out.
- No cap. Raise your rate, add hours, or don't. An employed rate moves when the employer says so.
- Employed hours aren't always guaranteed. The employed column assumes your hours run 52 weeks a year. Plenty of employed cleaning is zero-hours, where quiet weeks shrink the pay packet too - without the higher rate to make up for it.
The assumptions behind the numbers
- Tax year 2025/26 figures: personal allowance £12,570; income tax 20% to £50,270, 40% above; employee National Insurance 8% above £12,570 (2% above £50,270); self-employed Class 4 NI 6% above £12,570 (2% above £50,270). Class 2 NI no longer needs paying.
- Employed pay assumes 52 paid weeks including 5.6 weeks' statutory holiday. Auto-enrolment pension: 5% from you and 3% from the employer, on earnings between £6,240 and £50,270. Your 5% is shown deducted from take-home, and the pot shown includes basic-rate tax relief and the employer's 3%.
- Self-employed income counts only the weeks you work. Public liability insurance of £60/yr is included in costs. Pension contributions are shown deducted from take-home, with basic-rate tax relief added to the pot.
- Simplifications: no student loan, no other income, no Marriage Allowance, mileage entered as a flat weekly cost rather than the 45p/mile method. Real tax returns have more moving parts.
- Rates checked August 2026: the employed default is the real Living Wage (£13.45/hr, Living Wage Foundation 2025/26), which the best local cleaning employers subscribe to; most employed cleaning ads around Winchester/Southampton pay £12.20-12.90/hr.
