Murph revenue math for CrossFit boxes is straightforward but rarely written down. The annual Memorial Day Murph apparel program covers itself, funds a meaningful donation to a veterans charity, and leaves the box with a small treasury surplus for the season. Here is the full math at three box sizes plus multi-year cumulative projections.
Standard per-athlete economics for box Murph:
| Tier | Athlete pays | Apparel cost | Box gross profit | 50% donation | Box net |
|---|---|---|---|---|---|
| Standard | $45 | $19.88 | $25.12 | $12.56 | $12.56 |
| Plus finisher | $95 | $56.76 | $38.24 | $19.12 | $19.12 |
| Family bundle | $120 | $59.64 | $60.36 | $30.18 | $30.18 |
The 50% donation split is the most-used default. Some boxes go to 100% donation; others retain more for box-treasury reinvestment.
Projection at three box sizes with 50% donation split:
| Box size | Murph participants | Avg revenue per athlete | Gross profit | Donation | Box net |
|---|---|---|---|---|---|
| Small (30 members) | 22 | $45 | $553 | $276 | $276 |
| Medium (100 members) | 75 | $55 | $2,634 | $1,317 | $1,317 |
| Large (200 members) | 150 | $60 | $6,018 | $3,009 | $3,009 |
| Multi-location (500 members) | 400 | $60 | $16,048 | $8,024 | $8,024 |
Boxes that run Murph annually see compound participation growth from community memory and recurring engagement. Standard 5-year trajectory for a medium box:
| Year | Participants | Box net | Annual donation | Cumulative donation |
|---|---|---|---|---|
| 1 | 30 | $754 | $754 | $754 |
| 2 | 50 | $1,256 | $1,256 | $2,010 |
| 3 | 75 | $1,884 | $1,884 | $3,894 |
| 5 | 120 | $3,014 | $3,014 | $10,160 |
| 10 | 250 | $6,280 | $6,280 | $33,000+ |
The cumulative donation is the box's permanent community-impact story. Many boxes post the cumulative total prominently as a recurring participation driver.
Beyond the core Memorial Day participation, three smaller revenue lines compound:
Five-step setup at $0 upfront cost:
Total setup time: under an hour. The shop accepts orders, handles printing and shipping, and tracks the donation total automatically.
Free apparel storefront, no minimum, no upfront cost. Start at $0 and grow community impact year over year.
Start Free$40-60 for standard tier (workout + event tee); $85-105 for plus-finisher tier (workout + tee + finisher hoodie). Adjust based on box demographics.
30-50% of profit is standard. Some boxes go to 100% donation; others retain more for box-treasury reinvestment in community programming.
Setup is under an hour; revenue starts as soon as registration opens. Most boxes see the bulk of registrations in the 2-3 weeks before Memorial Day.
Yes. Even at 20-25 participants, the box clears $400-700 plus the same donation amount. The community impact and recurring participation make it sustainable.
