Understanding CPA & ROAS Targets

Target CPA

  • • Maximum cost per acquisition
  • • Based on LTV and target ratio
  • • 3:1 LTV:CAC is standard benchmark
  • • 5:1 LTV:CAC allows aggressive scaling
  • • Lower CPA = more profitable growth

Target ROAS

  • • Revenue per dollar of ad spend
  • • Break-even ROAS = 1 / margin
  • • Target = break-even × profit multiplier
  • • 50% margin → 2:1 break-even ROAS
  • • Higher ROAS = more efficient spending
