How to Calculate Profitable ROAS Targets for Your Shopify Store
Stop borrowing other people’s ROAS goals. Your profitable number comes from your margins — here is the five-minute calculation.
Why a 4x ROAS Can Lose Money (and 1.8x Can Win)
ROAS is only meaningful relative to your margin. A store selling $100 products that cost $80 all-in needs a 5x ROAS to break even. A store with 70% margins breaks even at 1.4x. Copying a guru’s target number is how profitable campaigns get killed and money-losers get scaled.
The Five-Minute Calculation
Start with AOV. Pull it straight from Shopify analytics.
Subtract per-order costs. Product, shipping, payment fees, packaging, and returns allowance. What remains is contribution margin.
Break-even ROAS = AOV ÷ contribution margin. A $60 AOV with $25 margin means 2.4x break-even.
Set your target above it. Add 20–30% headroom for profit and noise: in this example, a 3x target.
When to Accept a Lower Target
If customers reliably reorder, first-order break-even is a valid strategy — you are buying a future stream, not one sale. Consumables, refills, and subscription-friendly products can happily run at break-even ROAS while the LTV math prints in the background.
Targets Are for Decisions, Not Decoration
Above target for a week: raise budget ~20%. Below break-even for a week: change the creative or offer, not the settings. Stirling makes the creative side of that decision instant — fresh static variations generated and published to Meta in about a minute.
