How do I calculate the effective price?

Formula: (base membership × months + joining fee + all service charges + training/starter package) ÷ months. Calculate over at least 12 months, so that flexible plans don't look overpriced because the one-off costs land in a single month.

Why does the effective price differ from the advertised monthly fee?

Because the monthly fee almost never includes all mandatory costs. A joining fee (often €20–50), half-yearly service charges (e.g. €20–25) and a mandatory training package (€30–80) push up the real monthly price. In the FFF dataset of 6,414 studios, the effective price is on average around 5% above the teaser price — that's roughly 20,00 € in extra costs per year.

Is the effective price the same as the total price?

No. The total price is the sum over the entire term. The effective price is the monthly allocation of it — directly comparable to the advertised monthly fee, but honest.

What is the effective price of a gym?

The effective price is the real monthly price of a gym membership — base membership plus all mandatory costs (joining fee, service/administration charge, training/starter package), spread evenly across the contract term. Nationwide it averages 42,46 € per month — around 5% above the advertised base membership. Data basis: 6,414 studios.

The formula

Effective price = (base membership × months + joining fee + all service charges + training package) ÷ months

Always calculate over at least 12 months — otherwise flexible plans are artificially inflated by one-off fees. Fair for Fitness applies this methodology consistently to every recorded studio.

Worked example

Advertised: 19,90 €/month, 24-month term. On top of that come:

+ 30,00 € joining fee (one-off)
+ 20,00 € service charge × 4 half-years = 80,00 €
+ 50,00 € training/starter package (one-off)

Total cost: 19,90 € × 24 + 30,00 € + 80,00 € + 50,00 € = 637,60 €

Effective price: 637,60 € ÷ 24 = 26,57 €/month — 34% above the teaser price of 19,90 €.

Why this term matters

• Comparability: Two studios with the same teaser price can differ significantly in effect — the effective price makes them honestly comparable.
• Contract decision: Only the effective price shows whether a seemingly cheap contract is really cheap.
• Effective price ≠ effective interest rate: You may know the term from loans — the idea is the same: fairly allocate all mandatory costs onto a single comparison figure.
