Shopify Breakeven ROAS Calculator — never run unprofitable ads again

Most Shopify and DTC brands scale ad spend without knowing their breakeven ROAS — the exact Return on Ad Spend below which every sale loses money. This free breakeven ROAS calculator uses your AOV, COGS, shipping cost and Shopify processing fee to show the minimum ROAS you must hit on Meta, Google or TikTok ads to stay profitable.

What is breakeven ROAS and why does it matter?

Breakeven ROAS = 1 ÷ Contribution Margin %. If 40 paise of every ₹1 in revenue is margin (after COGS, shipping, payment fees), your breakeven is 1 ÷ 0.40 = 2.5×. Spend ₹100 on ads, you need ₹250 in attributed revenue just to cover variable costs. Anything below 2.5× is bleeding cash.

How to calculate breakeven ROAS — formula

Contribution Margin % = (AOV − COGS − Shipping − Processing Fee) ÷ AOV Breakeven ROAS = 1 ÷ Contribution Margin % Target ROAS = Breakeven ROAS × (1 + desired profit margin)

Worked example

AOV $80, COGS $25, shipping $8, Shopify Basic processing 2.9% + $0.30 = $2.62. Contribution = $80 − $25 − $8 − $2.62 = $44.38. Margin = 55.5%. Breakeven ROAS = 1.80×. To hit 20% net profit, target ROAS ≈ 2.4×.

Blended vs platform ROAS — which one to trust?

Meta and Google over-attribute. After iOS 14.5 and the cookie-pocalypse, in-platform ROAS is often 30–60% inflated. Track blended ROAS = total store revenue ÷ total ad spend in a sheet weekly. That number should always be above your breakeven.

How to lower your breakeven ROAS

  • Increase AOV with bundles, free-shipping threshold and upsell apps
  • Negotiate lower COGS once you hit volume tiers
  • Switch to a regional 3PL to cut shipping cost
  • Move to Shopify or Advanced plan to drop processing %
