How to Calculate Shopify Store Break-Even
Your Shopify store has both fixed and variable costs. Break-even is reached when your gross profit per order covers all fixed monthly costs. The challenge: ad spend is fixed upfront, but revenue depends on ROAS.
Gross Margin/Order = AOV × (1 − COGS%) − Processing Fee − Transaction Fee
Total Fixed Costs = Shopify Plan + Other Fixed Costs + Ad Budget
Break-Even Orders = Total Fixed Costs ÷ Gross Margin/Order
Ad Revenue = Ad Budget × ROAS
Monthly Orders from Ads = Ad Revenue ÷ AOV
Total Fixed Costs = Shopify Plan + Other Fixed Costs + Ad Budget
Break-Even Orders = Total Fixed Costs ÷ Gross Margin/Order
Ad Revenue = Ad Budget × ROAS
Monthly Orders from Ads = Ad Revenue ÷ AOV
What ROAS do I need to be profitable on Shopify?
Your break-even ROAS depends on your gross margin. For a store with 50% gross margin after COGS and processing fees, your break-even ROAS is roughly 1 ÷ 0.50 = 2.0x — meaning you must generate $2 of revenue for every $1 of ad spend just to cover product costs. Add fixed costs (Shopify plan, apps) and you typically need 2.5–3.5x ROAS to be meaningfully profitable. Stores targeting 20%+ net margin should aim for 4x+ ROAS.
Which Shopify plan should I start on?
Start on Basic ($29/mo) if you're under $5,000/month revenue. The 2% third-party transaction fee only applies if you use an external payment processor — using Shopify Payments eliminates it. Upgrade to the Shopify plan ($79/mo) when your transaction fee savings exceed $50/month, which happens around $5,000+ in monthly revenue with a third-party processor, or when the added staff accounts and reports are worth it to you.
