Gym cost calculator

A membership is only cheap if you use it. This works out the cost per visit at how often you actually go, and compares it against paying per session.

How this is calculated

Annual cost is the monthly fee times twelve, plus the joining fee and any extras. Visits are your weekly figure times 52.

Cost per visit divides one by the other. It is the only figure that tells you whether the membership is working.

The pay-as-you-go comparison applies the drop-in price to the same number of visits, so you can see the crossover point for your actual habit rather than your intended one.

Be honest about the visits figure. January intentions and February reality are different numbers, and the second one is the one that determines value.

Worked example

A £42 a month membership with a £25 joining fee costs £529 in the first year. At two visits a week, that is 104 visits and £5.09 each, comfortably better than a £9 drop-in. Drop to one visit a week and the cost per visit doubles to over £10, and paying per session becomes cheaper.

Common questions

How many visits make a membership worth it?

Divide the monthly fee by the drop-in price. At £42 a month against £9 a session you need about five visits a month before the membership wins.

What if I go a lot in January and stop?

Then use your average across the year, not your best month. Gyms are priced on the assumption that most members overestimate.

Are rolling contracts better?

More flexible, usually a little dearer. If there is any doubt you will keep going, the flexibility is normally worth the small premium.

Can I cancel a minimum-term contract?

Usually only in limited circumstances such as relocation or injury. Check before signing, since a twelve-month minimum term is a twelve-month commitment.
