Formula guide

Formula Used

1) Lead rate

Lead Rate = (Leads ÷ Reach) × 100

2) Trial conversion rate

Trial Conversion Rate = (Trial Signups ÷ Leads) × 100

3) Member conversion rate

Member Conversion Rate = (Memberships Sold ÷ Trial Signups) × 100

4) Lift percentage

Lift % = ((Campaign Value − Baseline Value) ÷ Baseline Value) × 100

5) Revenue

Revenue = Memberships Sold × Average Membership Value

6) Incremental revenue

Incremental Revenue = Campaign Revenue − Baseline Revenue

7) ROI

ROI % = ((Incremental Revenue − Campaign Spend) ÷ Campaign Spend) × 100

8) Overall lift index

Overall Lift Index = Average of valid lead, trial, member, and revenue lift percentages.

Helpful answers

Frequently Asked Questions

1) What does lift percentage mean for a gym campaign?

Lift percentage shows how much a campaign improved performance over a baseline period. It helps compare leads, trials, memberships, and revenue using the same basic percentage formula.

2) Why compare campaign results to a baseline period?

A baseline gives context. Without it, high campaign numbers may look impressive, yet still represent weak improvement. Lift measures change against normal performance, not just raw totals.

3) Which gym metrics matter most in this calculator?

The most useful inputs are reach, leads, trial signups, memberships sold, membership value, and campaign spend. These reveal both response quality and financial impact.

4) Can I use this for social media promotions?

Yes. You can use it for social ads, local email campaigns, referral pushes, landing pages, and seasonal offers. Any campaign with before-and-after results can fit this model.

5) What if my baseline value is zero?

If a baseline metric is zero, lift percentage is not mathematically reliable. The calculator marks those cases as unavailable rather than showing a misleading number.

6) Does ROI here represent full business profit?

No. This ROI estimates return from incremental membership revenue versus campaign spend. It does not subtract staff time, discounts, rent, or long-term retention costs.

7) Why include a target lift percentage?

A target helps compare actual campaign performance with your goal. It also makes reports easier to discuss with managers, owners, and sales teams.

8) Should I track value per member monthly or annually?

Use the revenue figure that best matches your reporting style. Monthly value works for short campaigns. Annual value works for lifetime-focused planning and bigger forecasts.
