“How much do I need to spend before Meta optimises properly?”
Meta needs about 50 optimisation events per ad set per week to leave the learning phase. Work out the daily budget that gets you there, how long a fair test takes, and what it costs.
Open the calculatorThese tools model the maths. They cannot see your campaign.
A calculator tells you whether the numbers could work. It has no idea whether your tracking fires, whether your audience is too narrow, or whether the objective matches the outcome you want. That is what the readiness check is for — it looks at the campaign itself and scores it out of 100.
Also useful: which Meta ad metrics matter for each objective, and what the paid plans include.
