What's it actually costing you to land a client?

Acquisition feels free when you don't run ads — but 10 hours a month on Instagram at your hourly value is $750. This calculator surfaces the dollars-plus-time cost per new client, and benchmarks it against client lifetime value.

Typical independent trainer CAC: $317/client at 15.1% of CLV

$200 in monthly marketing spend plus 10 hours at a $75 hourly value is $950 — three new clients per month puts CAC at $317. Against a $2,100 CLV, that's right on the healthy/watch boundary.

How this is calculated

Most trainers think acquisition is free because they don't run ads. It isn't — the time you spend on Instagram, content, discovery calls, and networking has a real opportunity cost. CAC counts both dollars AND time, divides by clients acquired, and compares to the value of the relationship.

  1. 1
    Time cost of marketing
    hours/month × hourly value

    Use your true hourly rate as the hourly value, not your session rate — that's the honest cost of an hour of your time. 10 hrs at $75 = $750/month going to acquisition.

  2. 2
    Total acquisition investment
    marketing spend + time cost

    This is the real number, not the line-item ad budget. A trainer doing $0 in ads and 15 hrs/month of content is spending more than one running $500/month in ads and 5 hrs of oversight.

  3. 3
    Cost per client (CAC)
    total investment ÷ new clients per month

    If you acquire fewer than 1 client/month, the ratio inverts and CAC explodes — that's a signal to either lower the time investment or raise output (more efficient funnels).

  4. 4
    CAC-to-CLV ratio
    (CAC ÷ client lifetime value) × 100

    Under 15% = healthy growth zone. 15–25% = watch zone, sustainable but worth optimizing. Above 25% = unsustainable — you're paying more to acquire than the client returns.

FAQ

What counts as 'marketing hours'?
Anything you do to bring in new clients that you don't bill for: Instagram / TikTok / YouTube content (filming, editing, posting), networking events, discovery / consultation calls with prospects who haven't paid yet, content writing, lead-magnet creation, follow-up DMs and emails to leads. NOT included: time with paying clients, programming, admin for existing clients — that's delivery, not acquisition.
How should I calculate my hourly value?
Use your true hourly rate, not your session rate. Most trainers earn 40–60% less per hour than their session price suggests once unpaid hours are counted (see the True Hourly Rate calculator). Using session rate inflates the time cost and makes CAC look worse than reality. Using a lowball number lets you fool yourself that 'free' marketing channels are free.
What's a 'good' CAC for a personal trainer?
The dollar number depends on CLV, so the ratio matters more than the raw cost. A $400 CAC against a $5,000 CLV is healthy (8%). A $150 CAC against a $500 CLV is unsustainable (30%). For typical 6-12 month client tenures with $200-300/month packages, healthy CAC sits between $150-450 with the ratio under 15%.
How do I estimate client lifetime value (CLV)?
Multiply your average monthly revenue per client by your average client tenure in months. If clients pay $300/mo and stay an average of 7 months, CLV = $2,100. If you don't have data yet, use industry averages (5-8 months tenure is typical for independent online coaches; 6-12 months for in-person 1-on-1).
Which channels have the lowest CAC?
Referrals (typically $50-150 CAC, often just incentive costs + a few hours of nurture). Local partnerships and Google My Business (warm intent, low time cost). Organic social and paid ads sit higher ($200-600 range) because the time-to-conversion is longer. The article underneath this calculator breaks down each channel with typical spend, time investment, and CAC ranges.
