Business calculators for personal trainers

Four quick calculators for the money side of coaching: what to charge per session, how many clients fit your week, how many members a studio or app subscription needs to break even, and what a client is worth over time. Everything runs in your browser; nothing is saved or sent.

Every starting number is an example input. The values filled in below are made-up examples to show how each calculator works. They aren't typical prices, costs or incomes, and they aren't advice. Replace them with your own numbers.

Free for every trainer and coach. No sign-up, no paywall, ever.

Session pricing · Client capacity and income · Break-even · Client lifetime value

1. Session pricing

Works back from the monthly take-home you want to the price each session needs. Price = (take-home ÷ (1 − tax set-aside) + monthly costs) ÷ sessions per month.

Monthly take-home goal, $ (example)

Monthly business costs, $ (example)

Tax set-aside on profit, % (example)

Paid sessions per week (example)

Weeks worked per year (example)

2. Client capacity and income

How many sessions and clients fit into the hours you coach, and the revenue at the share of those slots you actually fill.

Coaching hours per week (example)

Session length, minutes (example)

Gap between sessions, minutes (example)

Sessions per client per week (example)

Price per session, $ (example)

Weeks worked per year (example)

Share of slots filled, % (example)

3. Break-even for a studio or app subscription

Members (or online subscribers) needed each month to cover fixed costs such as rent, software and insurance. Break-even = fixed costs ÷ (price − payment fees − per-member costs), rounded up.

Fixed costs per month, $ (example)

Price per member per month, $ (example)

Payment fees, % of price (example)

Other costs per member per month, $ (example)

4. Client lifetime value

What an average client brings in over the time they stay, after your direct costs. Lifetime value = monthly revenue × margin × months as a client. If you know your monthly churn instead, months = 100 ÷ churn %.

Revenue per client per month, $ (example)

Margin after direct costs, % (example)

Retention input

Average months as a client (example)

Cost to win one client, $ (example, optional)

These are planning sums, not tax, legal or financial advice. The tax set-aside is a number you choose; ask an accountant what applies to you.
