How break-even CPA is calculated
Simple logic: what you earn from a customer is what you can afford to spend on them.
Max CPA = order value × margin × purchases
Two practical examples
Ecommerce, one-time purchase
AOV $60, 40% margin, customer buys once.
Max CPA = 60 × 0.4 × 1 = $24
Safe target: $17 (70% of break-even). Aggressive: $22.
Subscription, repeat purchases
AOV $30/mo, 60% margin, average retention 12 months.
Max CPA = 30 × 0.6 × 12 = $216
High LTV allows more aggressive acquisition. Safe target: ~$150.
