ROAS Calculator

Calculate return on ad spend, ROI percentage, and break-even point. Industry benchmarks included.

Quick Takeaway

ROAS = Ad Revenue ÷ Ad Spend. A 3x ROAS means every $1 spent on ads generates $3 in revenue. Break-even is 1.0x — below that you lose money. E-commerce averages 3-4x, SaaS averages 2-3x, B2B services average 1.5-2x. Note: ROAS measures revenue, not profit — a 3x ROAS with 50% product margin yields only $0.50 profit per $1 spent. Profitable ROAS = 1 ÷ Gross Margin %. At 50% margin, you need 2x ROAS to break even on profit.

Limitations & Best Practices

  • ROAS is not profit: A 3x ROAS means $3 revenue per $1 spent, but if your product costs $2 to make, profit is only $1. Always calculate gross margin-adjusted ROAS: Profitable ROAS = 1 ÷ Gross Margin %. For 50% margin, you need 2x ROAS to break even on profit.
  • Attribution windows matter: ROAS depends on your attribution model (7-day click, 28-day view, etc.). Different platforms use different windows — compare ROAS only within the same attribution setup.
  • Blended vs. channel ROAS: This calculator handles single-campaign ROAS. For blended ROAS (all channels combined), sum total revenue and total spend across all channels first.
  • Time period alignment: Ad spend and revenue must cover the exact same period. If you spend in January but revenue comes in February (long sales cycles), your ROAS will look artificially low. Use cohort-based analysis for long cycles.
  • Organic halo effect: Paid ads often drive organic search and direct traffic. Last-click ROAS understates true impact. Consider incrementality testing for accurate measurement.
  • Return/refund adjustments: Use net revenue (after returns and refunds), not gross revenue. High-return products (fashion, electronics) can make ROAS look 20-30% better than reality.
  • Campaign-level only: This calculator computes ad-campaign ROAS. It does not factor in operating overhead (salaries, rent, software) or fixed business costs. The "Net Profit" shown is profit after ad spend only, not company-wide net income.
  • Use our CAC Calculator for customer acquisition cost analysis, and CLV Calculator for lifetime value modeling.

Frequently Asked Questions

What is the formula for ROAS?

ROAS = Total Ad Revenue ÷ Total Ad Spend. For example, if you spend $5,000 on ads and generate $15,000 in revenue, ROAS = $15,000 ÷ $5,000 = 3.0x. This means every dollar spent on ads returned three dollars in revenue.

What is a good ROAS?

It depends on your industry and gross margin. E-commerce: 3-4x is average, above 5x is excellent. SaaS: 2-3x is average due to longer sales cycles. B2B services: 1.5-2x is typical. The real question is whether your ROAS exceeds your break-even threshold: Break-even ROAS = 1 ÷ Gross Margin %. At 50% margin, you need 2x ROAS to break even on profit.

What is the difference between ROAS and ROI?

ROAS (Return on Ad Spend) = Revenue ÷ Spend (revenue multiple). ROI (Return on Investment) = (Revenue - Spend) ÷ Spend × 100 (profit percentage). A 3x ROAS equals a 200% ROI. ROAS tells you the revenue multiplier; ROI tells you the actual profit percentage. Both are useful — ROAS for media buying, ROI for business decisions.

How do I calculate break-even ROAS?

Break-even ROAS = 1 ÷ Gross Margin Percentage. If your gross margin is 60%, break-even ROAS = 1 ÷ 0.60 = 1.67x. At 50% margin, it's 2.0x (this is why the Core Data table shows 2x as the typical profitable threshold). Higher margin means lower break-even ROAS. Always use gross margin (after product costs), not revenue margin, for this calculation.

Should I include organic revenue in ROAS?

No. ROAS should only include revenue directly attributed to paid ads. Including organic revenue inflates ROAS and makes ads look more efficient than they are. If you want to measure total business efficiency, use a blended metric: Total Revenue ÷ Total Marketing Spend (paid + organic labor).

How often should I calculate ROAS?

Weekly for active campaign optimization, monthly for business reviews. Daily ROAS is too noisy due to attribution delays and conversion lag. For businesses with long sales cycles (SaaS, B2B), use monthly or quarterly ROAS and supplement with leading indicators like cost per lead (CPL) and conversion rate.

Why is my ROAS dropping even though spend is the same?

Common causes: ad fatigue (same audience seeing same ads), increased competition (auction prices rising), seasonality, landing page performance drops, or attribution window changes. First check frequency caps and creative refresh schedule, then compare auction metrics (CPM, CPC) to previous periods.

Is my data sent to your servers?

No. All calculations run locally in your browser. Your ad spend and revenue numbers are never sent to our servers or any third party. Page visit analytics (anonymous, no input data) may be collected by Cloudflare. Your financial metrics never leave your device.
