Is the Scaling Readiness check free?
Every account gets one free run, then it's 1 credit each (free monthly credits cover normal use).
Does it predict my CPA at the higher budget?
No — nobody honestly can, because scaling changes the auction you're competing in. It computes your break-even and cushion from your real numbers and reasons about what's likely to break first, framed as risk management with step sizes and signals to watch — not a forecast.
What's break-even ROAS?
The ROAS below which you lose money, worked out from your gross margin: at a 40% margin you break even at 2.5x ROAS. Knowing it tells you exactly how much room your current performance has before scaling pushes you underwater.
What numbers do I actually need?
At minimum, your gross margin % (or AOV so it can derive economics) plus one of current CPA or ROAS, and the spend you want to scale to. The more you give, the sharper the reasoning.
