Break-Even ROAS Calculator
Find the minimum return on ad spend your campaigns need just to cover costs. Every ROAS above this number is profit. Every ROAS below it is bleeding cash.
Hitting your ROAS target starts with ads that convert
Break-even is a floor, not a ceiling. The brands clearing it consistently ship fresh UGC-style creative every week. MagicFit makes that volume achievable without hiring an agency.
How to use this Break-Even ROAS Calculator
Break-even ROAS is the single most important number in your ad account. Above it you are profitable. Below it you are losing money on every sale, regardless of what the platform dashboard says. Your payment processor has already taken fees before revenue hits your bank account, so never treat the ad manager's reported ROAS as real ROAS without accounting for COGS, shipping, and fees.
The gap between break-even ROAS and your actual ROAS is your margin of safety. If your break-even is 2.5x and you are running at 3.0x blended, any week that drops 15 percent wipes you out. Aim for at least 30 to 50 percent headroom above break-even before you scale spend. Use the max CAC number to guide prospecting: that is the most you can pay for a new customer before the first order is unprofitable. First-order CAC at break-even only makes sense if you trust your repeat purchase rate to pick up the slack.
Run this monthly. AOV drifts when you launch new products or run promotions. COGS drifts when you change suppliers or freight rates shift. Set a calendar reminder the first of every month.
