How the calculation works
Revenue ÷ ROAS = Budget
Your required budget is simply your target revenue divided by your ROAS. If you want $10k revenue at 3x ROAS, you need $3,333 in spend.
Budget ÷ AOV = Orders
Revenue divided by your Average Order Value gives projected orders. CPA is then budget divided by orders — your maximum cost per sale.
