How do I choose a target ROAS?

Start from your break-even ROAS (1 ÷ margin), then add a buffer for overheads and profit. Many brands target 1.5–2× their break-even figure.

Does this account for ramp-up time?

It gives a steady-state budget. New campaigns usually need a learning period where efficiency is lower, so budget some headroom in the first few weeks.

How to use the ad budget calculator

Required ad spend = Revenue goal ÷ Target ROAS

Working backwards from a revenue goal keeps budgets grounded in outcomes rather than guesswork.

Your target ROAS should sit above your break-even ROAS — use our break-even calculator first if you're unsure.

The daily budget helps you pace spend and spot early whether you're tracking toward the goal.
