Calculate customer acquisition cost for a digital product business across ads, content, software, agency, and affiliate spending. Use it to judge whether paid growth is sustainable relative to LTV.
CAC measures how much it costs to acquire one customer. It should be evaluated against LTV, not revenue alone.
For digital products, CAC varies widely: templates may be $10–$40, courses $20–$80, memberships $50–$150, and software higher.
If total marketing cost is $7,350 and 140 customers are acquired, CAC is $52.50. With $300 LTV, the LTV:CAC ratio is 5.7:1.
A good CAC depends on LTV, but many businesses target an LTV:CAC ratio of at least 3:1 and preferably 5:1 or higher.
Improve conversion rates, use retargeting, build organic traffic, refine targeting, and increase referral or affiliate efficiency.
You can include them for blended CAC, but paid CAC should be calculated separately to judge ad performance accurately.
A 3:1 ratio is often considered workable, while 5:1 or higher gives more room for scaling and profit.
Your maximum CAC should be based on gross profit LTV, payback period, cash flow, and growth goals.
