PT calendar ceiling calculator
Punch in your session rate, sessions a week, costs, and tax. See where the gym floor caps your income, and what's actually left after costs and HMRC take their slice.
Your sessions and rate
Costs and tax
Business costs cover gym rent or floor fees, kit, insurance, software, and anything else that eats into revenue before you get paid. Tax rate is a rough blend: 20-30% is typical for UK self-employed trainers once income tax and National Insurance land.
Gross ceiling
Take-home
What your own app opens up
Move delivery into your own app and your take-home could land near £176,000/year while giving you back 18 sessions a week. That's £142,000 of net headroom the gym floor has been hiding, after costs and tax.
Illustrative. Your actual numbers depend on your niche, pricing, and how much of your training can sit inside software. The scenarios below use conservative revenue multipliers and add running costs on top of yours.
Three ways to break the ceiling
Small-group training
2.0× grossSame slots, more clients per slot
Run semi-private sessions of 3 to 4 clients instead of 1-on-1. Effective rate roughly doubles, your floor hours stay the same, costs barely move.
Online programmes
3.0× grossApp-delivered training, fewer live sessions per client
Structured programmes delivered through an app, with live sessions reserved for form checks and reviews. Adds roughly £150/mo for app and delivery tooling (estimate, varies by provider).
Branded app + watch
5.0× grossYour own app delivers, you coach the exceptions
Your training method lives in your own app and smartwatch companion. Clients self-serve the workout, you step in where it counts. Adds roughly £250/mo for hosting, AI, and App Store fees (estimate, varies with scale).

Who should use the PT calendar ceiling calculator
This calculator is for personal trainers who charge per session and suspect the gym floor is capping their income. If you're booked back-to-back, turning enquiries away, or watching your earnings drop every time you take a week off, the ceiling is already pressing down. This tool puts a number on it.
It isn't for trainers who already sell app-based programmes with no per-client time cap (you've broken the ceiling). And it isn't a full business audit. For the why behind the maths, read our deep dive on why personal trainers hit a calendar ceiling and the routes through it.
If you've decided the model has to change, see what we build for trainers on the custom software for personal trainers page: branded client apps, workout builders, AI form coaching, and native smartwatch companions.
How the calendar ceiling calculation works
The calculator takes five inputs: your session rate, sessions per week, working weeks per year, monthly business costs, and tax rate. From those, it computes your gross annual ceiling (rate times sessions times weeks) and your net take-home after costs and tax.
Then it projects three ways to grow. Small-group training (2x gross) keeps your live sessions the same but puts 3 to 4 clients in each slot. Online programmes (3x gross) deliver structured training through an app, cutting live sessions per client. A branded app and watch companion (5x gross) puts your method in software you own, so the app delivers the workout and you step in where it counts.
Each scenario adds realistic running costs so the take-home reflects net, not gross. If the branded-app number changes your thinking, the next step is a free audit where we map exactly which parts of your delivery can move into software.
Everything trainers ask us about this calculator
How do I calculate my personal training income ceiling?
Multiply your session rate by the number of sessions you run each week, then by your working weeks per year. That's your gross annual ceiling. Subtract your business costs and tax to get the take-home figure. The calculator does this automatically and projects three ways to grow past it.
What session rate and tax rate should UK trainers use?
Average UK personal trainer rates sit around £24 to £40 a session, with experienced and London-based trainers charging more. For tax, 20% to 30% is a reasonable blend for self-employed trainers once income tax and National Insurance are combined. Check with an accountant for numbers that match your setup.
Are the growth scenarios realistic?
The 2x, 3x, and 5x multipliers are conservative estimates based on how trainers move from 1-on-1 to small-group, online programmes, and a branded app. Actual results depend on your niche, pricing, and how much of your training can be delivered through software. Treat the scenarios as directional, not promises.
Why does the branded app scenario show higher monthly costs?
An app you own has ongoing costs the floor doesn't: hosting, AI, payments, and App Store fees. Around £250 a month is a rough estimate for a mid-size build (actual costs vary with usage and scale). We include these so the take-home figures reflect real net, not a fantasy number.
Can I share my calculator results?
Yes. Hit the 'Share your numbers' button and the current URL copies to your clipboard with all inputs embedded as query parameters. Anyone who opens that link lands on the calculator with your exact scenario already filled in.
Who is this calculator for?
Personal trainers and online coaches who are booked out and feeling the cap. If you're turning clients away, training back-to-back to hit your number, or know your income drops the moment you take a week off, this gives you a concrete read on what moving delivery into software could open up.
