Before hitting the ceiling
Comfortable runway — roughly 7 months before costs cross your ceiling. Use the time to test the next channel before you need it.
Rising CPA compounds, so saturation arrives faster than a linear read suggests. Diversify while a channel is still efficient, not after it breaks.
About this calculator
