Are these results a revenue guarantee?

No. This is a scenario tool: it models incremental value/LTV from the assumptions you enter. It does not guarantee results or revenue recognized within the same accounting period.

Why is the conversion improvement measured in percentage points?

Because it is the least ambiguous way to express it. Going from 20% to 23% is +3 percentage points, not +3% relative. With 300 monthly leads, those 3 points equal 9 additional sign-ups per month.

Why is retention value calculated only on the existing base?

To avoid double counting. The incremental members gained through higher conversion are already valued with the new lifetime inside the conversion block.

Is the result net profit?

No. It is estimated incremental value and, once software cost is deducted, incremental value net of the Wizfood cost. It does not account for the gym's variable costs.

Does the calculator convert currencies?

No. The selector only changes symbol and formatting: all inputs and results stay in the currency you choose.

What would converting a little more and retaining members a little longer be worth to your gym?

Part of the WizFit ecosystem

Use your own numbers to estimate the incremental value nutrition could add through higher conversion and longer member lifetime.

Short answer

Two levers drive most of a gym's economics: how many leads become members, and how many months each member stays. A small improvement in either one is usually worth far more than the monthly cost of software.

This calculator models both levers separately, using your own assumptions, and shows the estimated incremental value they could generate from 12 months of operation. No preset scenarios, no Wizfood averages — you control the sliders.

What this calculates

This calculator models incremental value/LTV based on the assumptions you enter. It is not a revenue guarantee, nor necessarily revenue recognized within the same accounting period.

Example scenario — adjust it to your own hypothesis. The starting values are editable examples, not Wizfood benchmarks.

Wizfood is the nutrition solution within the WizFit ecosystem, designed to bring nutritional support into the gym member experience.

Why can nutrition influence these two metrics?

A more complete value proposition

Wizfood makes it possible to bring nutrition into the experience your gym offers. For a prospective member, that can make the offer feel more complete than a membership focused only on access and training.

Training + nutrition = a more complete value proposition.

More guidance along the member journey

Wizfood adds a layer of nutritional guidance that can extend the member's relationship with the gym: follow-up, habits, goals and continuity beyond training itself.

More touchpoints can mean a deeper relationship with the member.

The calculator does not assume these improvements will happen automatically. You choose the conversion and retention uplift you want to model, and Wizfood calculates what that scenario could be worth to your gym.

What if nutrition helped your gym convert a little more and retain members a little longer?

These are your assumptions, not Wizfood promises: you choose how much you believe these two metrics could move.

Conversion improvement

Model the impact of adding nutrition as part of a more complete value proposition.

Percentage points, not relative growth: going from 20% to 23% is +3 points.

Assumption: nutrition as part of a more complete value proposition at decision time.

Member lifetime increase

Model what longer retention could be worth when members get more nutritional guidance.

Extra months of retention on your existing member base.

Assumption: more guidance along the member journey, inside and outside the gym floor.

This shows what one additional month of retention on your current base is worth economically. The calculator lets you model what would happen if nutrition helped extend part of that journey.

The math, in plain terms

See how we calculate this

Conversion

leads × conversion improvement × 12 × monthly fee × new member lifetime

Each month's additional sign-ups accumulate over 12 months and are valued with the new lifetime, because those members also benefit from the improved retention.

Retention

active members × monthly fee × extra months

Applied only to your existing member base, never to newly acquired members.

Total

conversion value + retention value

How we avoid double counting

Incremental members are already valued with the new lifetime inside the conversion block. That is why the retention block uses only the existing base, and we never add new sign-ups × extra months again.

Estimated ROI on software cost

(total incremental value − annual cost) ÷ annual cost × 100

Questions this calculator answers

How much is one extra month of member retention worth? — For your existing base, one extra month is worth active members × monthly fee. With 1,000 members at a 50 fee, that single month represents 50,000 in estimated incremental value.
How do I calculate the LTV of a gym member? — A simplified member LTV is monthly fee × lifetime in months. If lifetime goes from 10 to 11 months at a 50 fee, LTV goes from 500 to 550.
How much can nutrition increase gym revenue? — It depends on your numbers. Nutrition acts on two levers: lead conversion (a more complete offer) and retention (perceived results). This calculator lets you model both with your own assumptions, without assuming any predetermined uplift.
How do I measure the ROI of nutrition software? — Compare the estimated incremental value from conversion and retention against the annual software cost. Estimated ROI is (incremental value − annual cost) ÷ annual cost.
