The rate is the business plan.
Most trainers pick a rate by looking at the trainer down the street. This calculator builds it from your own numbers: take-home goal plus business costs, divided by the sessions you can actually deliver in a year (not 52 fantasy weeks — real ones, with vacations and January cancellations). The answer is the minimum rate that makes the business work.
Trainers going independent use it before quitting the gym job: income goal plus costs over real session capacity gives the rate floor, and it is almost always higher than expected. Gym managers use it to show trainers why the 50/50 split is not the villain.
Rates vary widely by market — roughly $40–$75 in smaller markets, $75–$150+ in major metros, and more for specialists. But the right question is what YOU must charge: an $80k goal with $12k of costs over 1,150 sessions a year requires $80 per session, full stop.
Because you will not bill 52 weeks. Vacation, holidays, sick days, client travel, and the attendance dip after New Year's motivation fades all cut capacity. Planning on 46 weeks is still optimistic for many trainers — 44 is safer for a first plan.
Three levers: more sessions per week (limited by your energy), semi-private training (2–4 clients split the slot — the classic move), or online/hybrid clients who add revenue without adding gym hours. Lowering the income goal is the fourth lever, but know you are pulling it.
