ROAS Calculator: Return on Ad Spend Formula & Break-Even ROAS

• ROAS = Revenue Generated ÷ Ad Spend. A ROAS of 4× means you earned ₹4 for every ₹1 spent on ads. It is NOT the same as profit — ROAS ignores product costs, fulfilment, and overheads.
• The minimum ROAS to break even is determined by your gross margin: if margin is 40%, you need at least 2.5× ROAS to cover the ad cost alone (before other expenses).
• Target ROAS for e-commerce in India: 3–6× is considered healthy; below 2× usually means losing money; above 8× often signals underinvestment (leaving profitable sales on the table).
• Google's Target ROAS bidding strategy requires at least 50 conversions in the past 30 days to function reliably — below that, use manual or Target CPA instead.

Use our free ROAS Calculator to compute ROAS from revenue and spend, find the revenue needed to hit a target ROAS, and calculate your break-even ROAS from gross margin.

ROAS Formula — Three Directions

Mode 1 — Calculate ROAS: ROAS = Revenue ÷ Ad Spend

Mode 2 — Revenue needed for target ROAS: Revenue = Target ROAS × Ad Spend

Mode 3 — Max ad spend for target ROAS: Max Spend = Revenue ÷ Target ROAS

Worked Examples

Example 1: Facebook campaign: ₹40,000 spend, ₹1,92,000 revenue tracked. ROAS = ₹1,92,000 ÷ ₹40,000 = 4.8× ROAS

Example 2 — Goal setting: You want 5× ROAS. You have ₹1,00,000 to spend. Revenue needed = 5 × ₹1,00,000 = ₹5,00,000 revenue target

Example 3 — Reverse from revenue: Product generated ₹8,00,000 last month. You want 6× ROAS. Max ad spend = ₹8,00,000 ÷ 6 = ₹1,33,333 max budget

Break-Even ROAS: The Most Important Calculation

ROAS is not profit. A 3× ROAS can mean losing money if your gross margin is 25%.

Break-Even ROAS = 1 ÷ Gross Margin

Gross Margin	Break-Even ROAS	What It Means
20%	5.0×	Must earn ₹5 for every ₹1 ad spend just to cover costs
30%	3.33×	Need 3.33× ROAS to break even on ad spend
40%	2.5×	Need 2.5× ROAS to break even
50%	2.0×	Need 2× ROAS to break even
60%	1.67×	Need 1.67× ROAS to break even
70%	1.43×	Premium digital products

Example — Apparel brand with 35% gross margin: Break-even ROAS = 1 ÷ 0.35 = 2.86×

If ROAS is below 2.86×, every ad rupee is costing more than the margin it generates. Profitable ROAS for this brand must exceed 2.86× — and ideally 4–5× to cover other operating costs.

ROAS vs. ROI: The Critical Difference

These are often confused — they measure different things.

ROAS = Revenue ÷ Ad Spend (ignores all costs except ad spend) ROI = (Net Profit ÷ Total Investment) × 100 (includes all costs)

Example: Ad spend: ₹50,000 Revenue: ₹2,00,000 COGS (cost of products sold): ₹1,00,000 Other operating costs: ₹20,000

ROAS = ₹2,00,000 ÷ ₹50,000 = 4× (looks great) Net Profit = ₹2,00,000 − ₹50,000 − ₹1,00,000 − ₹20,000 = ₹30,000 ROI = ₹30,000 ÷ ₹50,000 × 100 = 60% (also good, but very different number)

A business with a 4× ROAS and 30% gross margin may have near-zero net profit — ROAS alone doesn't tell you if the business is viable.

Target ROAS Bidding on Google: When It Works

Google's tROAS (Target ROAS) smart bidding adjusts bids automatically to hit your ROAS goal.

Requirements for tROAS to work:

• Minimum 50 conversions in the last 30 days (ideally 100+)
• Conversion values must be tracked (not just conversion counts)
• Campaign has been running for 4+ weeks with stable settings

Setting the right target:

• Don't set target ROAS higher than your historical ROAS — Google will restrict spend to meet an impossible target
• Start 10–20% above your current average ROAS, then tighten gradually
• Monitor impression share — if it drops sharply, your tROAS target may be too aggressive

FAQ

What is a good ROAS for Facebook ads?

For e-commerce: 3–4× ROAS is considered healthy on Facebook. However, this depends entirely on your gross margin. A 3× ROAS with 50% gross margin is profitable; the same 3× with 25% gross margin is break-even at best. Always calculate your break-even ROAS first.

Why is my ROAS high but I'm still not profitable?

ROAS only measures ad revenue vs. ad spend — it excludes product cost, shipping, returns, customer service, platform fees, and other overheads. Calculate your break-even ROAS using gross margin, then add other costs to find your true profitable ROAS threshold.

How do I track ROAS accurately?

Implement purchase event tracking via Google Tag Manager on your thank-you/order confirmation page. Pass actual order value dynamically, not a fixed value. Use UTM parameters for cross-channel attribution. Note that iOS privacy changes have made Meta's reported ROAS less accurate — use a 3-day or 7-day attribution window for e-commerce.

What is blended ROAS vs. campaign ROAS?

Campaign ROAS: revenue attributed to a specific campaign ÷ that campaign's spend. Blended ROAS: total store revenue ÷ total ad spend across all channels. Blended ROAS is often more reliable as it avoids attribution disputes between channels. Many e-commerce brands target 3–4× blended ROAS as a health indicator.
