Break-even CPA = (AOV - COGS - Shipping - Processing) x (1 - Return Rate)Example: $5K Ad Spend with 3x ROAS
An ecommerce store spends $5,000 on ads and generates $15,000 in revenue. Looks like a 3x ROAS. But after all costs:
The Reality Check
What looked like a profitable 3x ROAS is actually a 0.57x true ROAS — you earn $0.57 in profit for every $1 spent on ads. The gap between standard and true ROAS is where most ecommerce businesses miscalculate profitability. Use our ecommerce profit calculator for a deeper unit economics breakdown.

Frequently Asked Questions
What is the difference between ROAS and true ROAS?
Standard ROAS divides total revenue by ad spend, ignoring all other costs. True ROAS subtracts COGS, shipping, payment processing, and returns before dividing by ad spend. A 3x standard ROAS can easily be a 0.5x true ROAS once all costs are accounted for, meaning you actually lose money on every ad dollar.
What is a good true ROAS?
A true ROAS above 1.0x means you are profitable on a first-order basis. Most healthy ecommerce businesses target a true ROAS of 1.5x-3x. Below 1.0x, you are losing money on every acquisition unless customer lifetime value makes up the difference. The right target depends on your repeat purchase rate and LTV — use our CAC payback calculator to factor in retention.
Why do my ads look profitable but I am losing money?
Ad platforms report revenue without deducting your cost of goods, shipping, returns, or payment processing fees. A product with 30% COGS, $5 shipping, 2.9% processing, and 8% returns already loses over 40% of revenue to fulfillment costs. When you add ad spend on top, the "profitable" 3x ROAS campaign may only generate $0.50 in real profit per dollar spent.
How do I calculate break-even CPA?
Break-even CPA is the maximum you can pay to acquire a customer and still break even on the first order. Calculate it as: (Average Order Value - COGS - Shipping - Processing Fee) x (1 - Return Rate). For a $75 AOV with 30% COGS, $5 shipping, 2.9% processing, and 8% returns, your break-even CPA is approximately $42.78. Any CPA above that means you need repeat purchases to become profitable.
Should I include return costs in ad profitability?
Absolutely. Returns represent revenue that was counted in your ROAS but never actually retained. An 8% return rate on $15,000 in ad-driven revenue means $1,200 you thought you earned goes back to customers. Failing to include returns is one of the most common reasons ecommerce businesses scale unprofitable ad campaigns. Track returns by channel to understand which campaigns drive the most returns.
