About this calculator
Should I target CPA on the first job or on lifetime value?
Lifetime value, if your repeat rate is real and measurable. Many home-service businesses can afford to break even on job one because maintenance and repeat work follow.
My CPA jumped this month: why?
Usually conversion rate, not click cost. Check whether leads were answered as quickly as usual before assuming the ad platform got more expensive.
The formula
CPA = spend ÷ conversions; maximum CPA = job value × gross margin
