How to Read This

  • CPL – what you pay to get a hand raised (a lead who enters your free trial funnel).
  • Cost per Free Trial – what it costs you in ad spend to get one 2-week free trial activated.
  • CAC – what you actually pay (in ad spend) to create one paying member after the trial.
  • Monthly Profit from New Members – how much profit the new paid members generate per paid month (the 2-week free trial period is not included here).
  • LTV per Member – total profit you make on one member over their average paid membership life, after the free trial.
  • Breakeven Time – how many paid months it takes for the profit from this free-trial cohort to pay back your ad spend.

Car Wash Benchmarks (Typical Ranges)

  • Lead → Free Trial Conversion: 20–40% on strong free-wash / free-week style offers.
  • Free Trial → Paid Member Conversion: 10–20% is common with a good onsite upsell and clear value.
  • Unlimited Plan Price: often around the price of 2 single washes (e.g., $20–$30/month).
  • Average Paid Membership Lifetime: 13–18 months depending on site, area, and plan mix.
  • Breakeven Target: elite operators aim to recover CAC in ≤ 2–3 paid months so they can scale aggressively.

How to Read This (Hormozi Simple)

  • CPL – what you pay to get a lead into your system.
  • CAC – what you pay to create one paying member on the intro offer.
  • Month-1 Profit – cash the intro month throws off. If this covers CAC, you scale aggressively.
  • Ongoing Profit – monthly profit from rebills, once the intro month is over.
  • LTV per Member – total profit per member across the whole average membership life.
  • Breakeven Time – how many months it takes this cohort to pay back your ad spend.

Car Wash Benchmarks (Typical Ranges)

  • Lead → Member Conversion: 3–8% for cold traffic offers; 8–15% with strong offer & in-person upsell.
  • Unlimited Plan Price: typically around the price of 2 single washes (e.g., $20–$30/month).
  • Average Usage: around 2.5–3.5 washes per member per month.
  • Average Membership Lifetime: 13–18 months depending on site maturity & plan type.
  • Month-1 Breakeven Target: elite operators aim to recover CAC in ≤ 2 months; anything ≤ 3 months is usually scalable.

Unit Economics & Profit Per Member

See how profitable each member really is once you factor in wash costs, usage, and retention — and how much you can safely spend to acquire them.

Inputs

Results

Revenue per Member / Month $0.00
Variable Cost per Member / Month $0.00
Profit per Member / Month $0.00
Profit Margin 0%
Lifetime Profit per Member (LTV) $0.00
Max CAC (to break even in target months) $0.00

How to Read This (Hormozi Simple)

  • Revenue per Member / Month – what you collect from one member each month.
  • Variable Cost per Member / Month – what it actually costs you in soap, water, power, etc. for their average usage.
  • Profit per Member / Month – what’s left over after wash costs. This is the money that pays back your marketing and fixed overhead.
  • Profit Margin – profit as a % of the membership price. Higher margin gives you more room to spend on growth.
  • LTV – total profit you earn from one member over the average membership lifetime.
  • Max CAC – the most you can pay to acquire a member and still break even within your target payback period.

Car Wash Benchmarks (Typical Ranges)

  • Unlimited Plan Price: commonly $20–$30/month, often set near the price of 2 single washes.
  • Average Usage: roughly 2.5–3.5 washes per member per month on unlimited plans.
  • Chemical Cost per Wash: often around $0.40–$0.80 depending on chemistry and equipment.
  • Total Variable Cost per Wash: (chemicals + water + power + wear) typically in the $0.70–$1.20 range.
  • Healthy Profit Margin: many strong operators run 60–75% margin on membership revenue before fixed overhead.

How to Read This (Hormozi Simple)

  • Starting Members – how many active members you have today.
  • New Members per Month – what your marketing and in-bay upsell add every month.
  • Monthly Churn – what percentage cancel each month. This is the leak in the bucket.
  • Members at End of Period – where your base lands after stacking growth and churn.
  • Peak Members – the highest member count you hit in the forecast window.
  • MRR at Final Month – recurring revenue you’re doing per month at the end.
  • Total Revenue – cumulative membership revenue over the whole forecast period.
  • Net Member Growth – how many more members you have vs where you started.

Car Wash Benchmarks (Typical Ranges)

  • Monthly Churn: 4–8% per month is common; best-in-class sites can drive this closer to 3–5%.
  • New Member Adds: strong marketing and in-lane selling can add 50–150+ members per month per site.
  • Membership Price: many sites cluster around $20–$30/month per plan on average.
  • Healthy Trajectory: if net members are growing by 5–10% per month, you are compounding fast.
  • Red Flag: if churned members ≈ or > new members for several months straight, the program is shrinking and needs an offer/experience fix.
