Enter your CAC and LTV inputs above
Fill in your marketing spend, new customers acquired, average order value, purchase frequency, and customer lifespan to calculate your LTV:CAC ratio.
Note. LTV is calculated as (AOV × frequency × lifespan × gross margin) discounted at your cost of capital. Referral value is added as an incremental benefit. Industry LTV:CAC targets vary. SaaS: 4:1+, E-commerce: 3:1, Services: 3:1+. A ratio below 1:1 means you lose money on every customer acquired. Payback period is calculated on gross profit basis.
