ROI of Gym Merch: Turn Every Apparel Drop into $1–2K

Operating Costs (optional) = Paid promo, platform fees, staff overtime

• Net Profit = Gross Profit − Operating Costs

• ROI = Net Profit ÷ COGS (or ÷ Total Costs if you include ops)

Your levers are simple: raise per-item margin and sell more units—without taking inventory risk.

Realistic Cost & Price Guardrails (So Your Math Works)

Use these planning bands that consistently work for community gyms:

• Tees (quality blanks + standard print):

  • All-in COGS: $15–$22

  • Retail: $28–$35

  • Margin target: $12–$18 per tee

   

• Fleece (crew/hoodie, simple decoration):

  • All-in COGS: $25–$45

  • Retail: $49–$65

  • Margin target: $20–$30+ per piece

Quick price formula:

Retail = COGS ÷ (1 − Target Margin).

Example: $15 tee cost at a 50% target margin → $15 ÷ 0.5 = $30 retail.

Keep designs clean (1–2 locations), SKUs tight (2–4 styles max), and you keep COGS down and conversion up.

Three Worked Scenarios to Hit $1–2K Profit

Plug your own numbers in, but these mirrors what 100–300-member gyms routinely achieve with a seven-day preorder and basic promotion.

Scenario A — Mixed Fall Drop(most common)

• Tees: 60 sold @ $30 retail, $14 margin → $840

• Hoodies/Crews: 40 sold @ $59 retail, $25 margin → $1,000

• Total Profit: $1,840

Why it works: One staple + one seasonal piece gives members an easy choice without decision fatigue.

Scenario B — 

Single-SKU Winter Fleece

• Hoodies/Crews: 60 sold @ $58 retail, $24 margin → $1,440

• Add a last-day push (+5 units) → +$120

• Total Profit: $1,560

Why it works: One hero product simplifies promotion and production, and cold weather boosts fleece demand.

Scenario C — Memorial Day
