The textbook answer is 3:1, LTVshould be 3x CAC. The truthful answer: it depends on your cash cycle, repeat purchase rate, and growth stage. Some of the healthiest DTCbrands we work with run at 1.8:1 because they're optimizing for growth and have patient capital. Others at 5:1 are probably underinvesting in growth.
Real benchmarks by DTC model
- →Consumable DTC(coffee, skincare, food): 4:1 to 7:1 at maturity. High repeat rate.
- →Fashion DTC: 2.5:1 to 4:1. Lower repeat, but higher AOV.
- →Durable goods (furniture, mattresses): 1.5:1 to 2.5:1. One-shot purchase.
- →Subscription DTC: 5:1 to 10:1 if churn is under 5%.
- →Luxury DTC: 2:1 to 3:1 acceptable given AOVeconomics.
When 3:1 is misleading
A 3:1 ratio calculated against 24-month LTVtells a different story than 12-month LTV. Always specify the time horizon. For payback-sensitive companies (most startups), 12-month LTV:CAC is the only ratio that matters. 24-month is for mature brands with strong retention.
What to do with the ratio
If your 12-month LTV:CAC is over 3:1, you are underinvesting in growth, push harder. If it's 1.5-3:1, you're in a healthy operating zone. If it's under 1.5:1 and has been for 3+ months, you have a unit economics problem that acquisition scaling will only worsen.
