One of the most common conversations I have with newly qualified PTs goes something like this: they are charging £40 a session, doing fifteen sessions a week, and doing the sum on the back of an envelope. Forty times fifteen times four times twelve. Great number. Then January arrives and HMRC would like a word.

What your hourly rate actually has to cover

When you are employed, your employer covers your pension contributions, pays for your holiday entitlement, and gives you statutory sick pay if you cannot work. As a self-employed PT, none of those things happen automatically. Every one of those protections has to come out of your hourly rate - because if it does not come from there, it does not come from anywhere. Adam Beard puts it plainly: a percentage of every hour you charge is your pension, your holidays, and your sick pay. The number that hits your bank is not what you earned. It is what is left after those things are accounted for, whether or not you have accounted for them.

Then there is tax. The self-assessment system requires you to pay tax on your profits in January. If you have not been setting money aside throughout the year, that January bill - which can run into thousands - can be genuinely destabilising. The discipline of saving a fixed percentage of every payment as soon as it arrives is not optional financial planning. It is professional basic practice.

The naive income projection problem

Dom Hills describes the mental trap that catches almost every new PT at some point: you multiply your session rate by the number of weekly sessions by 52 weeks and arrive at a satisfying annual figure. Our PT Income & Tax Calculator does this maths properly - factoring in tax, national insurance, and realistic working weeks so you get an honest number, not an optimistic one. The problem with the back-of-envelope version is that it assumes no illness, no client holidays, no slow January, no week where three clients cancel in a row. Real annual income is what you earn after accounting for all of that - and the gap between the projection and the reality is where a lot of early PT careers hit their first crisis.

The practical remedy is straightforward even if it requires discipline: build a savings buffer before you need it. Adam and Dom both recommend something close to five or six months of minimum-wage equivalent sitting in a savings account before you spend freely. Not because you expect disaster, but because the nature of self-employment is that surprises arrive - and a PT with savings makes good decisions when a client drops off, while a PT without savings makes desperate ones.

The conversation to have with yourself now

Before you set your session rate, do the real maths. What does the rate need to be to cover your actual costs - gym rent or commission, insurance, CPD, equipment - and still leave enough after tax and pension savings to live on? That figure is almost certainly higher than whatever you were considering. Charge accordingly. The alternative is spending the first year of your career financially fragile, making decisions driven by anxiety rather than strategy. That serves neither you nor your clients.
