Planning tool only Figures are for illustration. They are not financial, tax, legal, or clinical advice, and they may not match your contracts or accountant’s treatment.

What this calculator covers

This break-even number of sessions calculator is publisher content for UK private clinics, therapists, and physios. You supply monthly fixed costs, average session fee, and variable cost per session. It reports sessions to break even using the simplified assumptions described below—not as a substitute for an accountant, solicitor, or clinical record.

This is a dedicated version of break-even maths for session-based clinics. Contribution equals session fee minus variable cost; divide monthly fixed costs by contribution.

If contribution is zero or negative, raising prices or cutting variable costs must come first.

What this model does not do

This break-even number of sessions calculator is original publisher copy for UK private clinic administration. It is not a tax computation and does not apply HMRC rates, capital allowances, or Making Tax Digital rules.

The form cannot see your contracts, payer mix, or diary software. If a clause matters and there is no field for it, the output will not include it.
