How the ROAS Calculator Works
ROAS = Revenue from Ads ÷ Ad Spend
Break-Even ROAS = 1 ÷ Gross Margin (as decimal) = 100 ÷ Margin%
Profit = Revenue × Gross Margin% − Ad Spend
Example: Revenue $20,000 · Ad Spend $5,000 · Gross Margin 30%
ROAS = 20,000 ÷ 5,000 = 4.0 · Break-even = 100 ÷ 30 = 3.33 · Profit = $6,000 − $5,000 = $1,000

ROAS Calculator Frequently Asked Questions
What is a good ROAS?
Break-even ROAS depends on your gross margin. At 25% margin: break-even = 4.0. At 33% margin: break-even = 3.0. At 50% margin: break-even = 2.0. A 'good' ROAS is anything comfortably above your break-even, typically 4:1 to 8:1 for e-commerce.
What is the difference between ROAS and ROI?
ROAS measures gross revenue per ad dollar spent, it ignores all other costs. ROI measures net profit relative to total investment. A 4:1 ROAS sounds impressive but may be unprofitable if COGS is 70%. Always check ROAS against your break-even before judging campaign performance.
How do I calculate break-even ROAS?
Break-even ROAS = 1 ÷ Gross Margin. At 25% gross margin: 1 ÷ 0.25 = 4.0. This means you need $4 in revenue for every $1 in ad spend just to cover the cost of goods and ads. Any ROAS above this is profitable.
Why is my ROAS high but I'm still losing money?
ROAS only accounts for ad spend versus revenue. It ignores COGS, fulfilment, customer service, returns, overheads, and other expenses. A 5:1 ROAS at 15% gross margin only returns $0.75 revenue after COGS per $1 of ad spend, still a loss after factoring in other costs.
How do platforms like Meta and Google report ROAS?
Ad platforms report 'Purchase ROAS' = Purchase conversion value ÷ Amount spent, measured by their pixel/conversion tracking. Attribution window differences (1-day vs. 7-day click) and data discrepancies between platforms and your actual revenue data are common, so always reconcile with backend sales.
Are the numbers I enter into this calculator saved or tracked?
No. Every calculation runs right inside your browser using local code. Your salary, debts, and loan numbers stay completely private. Nothing is ever saved or sent to any server.
How should I account for taxes, inflation, and unexpected fees?
Most formulas show baseline estimates. In real life, keep local taxes, inflation, and bank fees in mind so your budget matches your actual costs.
