What each workout really costs

A gym membership is paid in monthly fees, but its value is measured in visits. A fee of 40 a month is a bargain for someone who trains three times a week and a waste for someone who goes once a month. This calculator divides the annual cost of the membership by your real visits and compares it with the single-visit price, showing how many times a week you need to go to break even.

It works in any currency and for any paid facility: gyms, swimming pools, climbing centres, yoga or dance classes with passes or drop-in prices.

How the calculation works

You enter the monthly fee, the joining fee and any annual fees, how many times you go per week, the single-visit price and how many weeks a year you actually attend.

• Annual membership cost: 12 monthly fees + joining and annual fees.
• Visits per year: visits per week × weeks of attendance.
• Cost per visit: annual cost divided by visits.
• Break-even: the visits per week at which the membership costs the same as paying each time.

The verdict is based on the cost per visit as a percentage of the single-visit price: a measure that holds in any currency and for any facility.

Your pace decides everything

The table uses a membership at 40 a month plus 50 of annual joining fee, that is 530 a year, a single visit at 12 and 46 weeks of attendance.

In this example break-even is at about one visit a week. Below it, the membership costs more than single visits; above it, every extra workout lowers the cost of all the others.

The January membership

Many people join with good intentions and then go less often. The table keeps the pace at two visits a week but changes the weeks in which you actually go, with the same 530-a-year membership.

The same pace, kept up only until spring, makes the membership more expensive than single visits. That is why it pays to enter the weeks you actually go, not the weeks you intend to go.

Paying not to go to the gym

Economists Stefano DellaVigna and Ulrike Malmendier, in a 2006 study titled "Paying Not to Go to the Gym", analysed thousands of members of US gyms. Those who had chosen a monthly membership went on average a little over four times a month, paying far more per visit than the price of the pay-per-visit pass they could have chosen instead. The explanation they propose is that when we sign up we tend to overestimate how often we will go. The calculator is there precisely to run the numbers with real figures.

The four bands of the verdict

• Below 50% of the single-visit price: the membership pays by a mile.
• 50% to 80%: it pays, if the pace holds.
• 80% to 100%: it barely pays, and a few skipped weeks cancel it out.
• 100% and above: at this pace, paying per visit is cheaper.

How to choose the right option

If you do not know how often you will go, try a month of single visits or a pass and count your real attendance. If you go regularly above the break-even threshold, the membership pays; if your pace varies a lot, a multi-visit pass often offers the best compromise. Before signing an annual contract, check the cancellation terms and whether you can freeze it for illness, holidays or moving.

What to weigh besides price

Cost is not the only criterion. For some people the membership is exactly what gets them there, because having already paid is motivating. Distance from home or work, opening hours, included classes and the presence of instructors also count. The calculator measures financial value: if a slightly more expensive membership makes you go more often, your final cost per visit can still end up lower.

Limits of the calculator

The model uses a constant average pace and does not include promotions, prepayment discounts, extra services such as classes, sauna or pool, or travel costs. If the membership includes services you would otherwise pay for separately, its real value is higher than the comparison with the single-visit price alone shows.

Frequently asked questions

How do you calculate the cost per gym visit?

Add up the annual membership cost, that is twelve monthly fees plus joining and annual fees, and divide it by the year's visits, that is visits per week times weeks of attendance.

When is a membership better than single visits?

When the cost per visit is lower than the single-visit price, that is when you go more often than the break-even threshold the calculator shows.

What is the break-even threshold?

The number of visits per week at which the membership costs exactly the same as paying each time. Below it, paying per visit is cheaper; above it, the membership pays.

How many weeks a year should I enter?

The weeks you actually go, minus holidays, illness and breaks. Entering the weeks you intend to go leads to underestimating the cost per visit.

Why do so many people overpay for memberships?

A 2006 study by DellaVigna and Malmendier showed that people signing up tend to overestimate how often they will go, ending up paying more per visit than the single-visit price.

How do I enter an annual membership paid upfront?

Divide the annual price by 12 and enter it as the monthly fee, leaving only joining and any extra fees in the annual fees.

Is a multi-visit pass worth it?

Often, when your pace is irregular: enter the pass's price per visit as the single-visit price to compare it with the membership.

Does it work for pools, yoga or climbing?

Yes, for any facility with memberships or single visits: enter the facility's fees and single-visit price.

What does the verdict percentage mean?

It is the cost per visit with the membership divided by the single-visit price. 48% means each workout costs you less than half the single-visit price.

Can a membership motivate me to go more?

For some people, yes: having already paid encourages training. If that happens to you, enter the pace you actually keep with the membership.

Does the calculator include classes and services?

No. If the membership includes classes, sauna or pool you would otherwise pay for, its real value is higher than the single-visit comparison alone.

Does it work in any currency?

Yes. Enter all prices in the same currency; the verdict is based on a percentage that does not depend on the currency.
