ROAS = Revenue ÷ Ad Spend

Use this free, online ROAS calculator to calculate your return on ad spend instantly, or switch the dropdown to work backwards and find revenue or ad spend instead. No sign-up, no limits just enter any two known values and it solves for the third.

What Is ROAS (Return on Ad Spend)?

ROAS, or return on ad spend, measures the revenue generated for every dollar spent on advertising. A ROAS of 4x (or 400%) means $4 in revenue was generated for every $1 spent. It’s the headline metric most e-commerce and performance marketing teams report on, and the one most often quoted without the context needed to actually judge it.

How to Calculate ROAS

To calculate ROAS, divide the revenue generated by a campaign by what you spent to generate it.

ROAS = Revenue ÷ Ad Spend

How to Calculate ROAS, Step by Step

  • Find the total revenue directly attributed to the campaign or period you’re measuring
  • Find the total ad spend for that same campaign or period
  • Divide revenue by ad spend

Worked Examples

  • Small campaign: $2,400 revenue, $600 ad spend $2,400 ÷ $600 = 4.00x ROAS (400%)
  • Mid-size campaign: $18,500 revenue, $5,200 ad spend $18,500 ÷ $5,200 = 3.56x ROAS (356%)
  • Agency-scale account: $210,000 revenue, $48,000 ad spend $210,000 ÷ $48,000 = 4.38x ROAS (438%)

Calculate ROAS Formula (Reverse Calculation)

Because this is a reverse-capable calculator, you can also start from a target ROAS and solve for revenue or ad spend instead.

  • To find Revenue: Revenue = ROAS × Ad Spend
  • To find Ad Spend: Ad Spend = Revenue ÷ ROAS

This is useful for setting a realistic budget. If your account typically returns 3.5x and you need $50,000 in revenue this quarter, you can work out roughly what ad spend that requires before you commit the budget.

Break-Even ROAS: The Number That Actually Matters

Almost every current benchmark report on ROAS agrees on one thing: a blended industry average is close to useless for judging your own account, because “good” depends entirely on your profit margin, not your industry. The number that actually tells you whether you’re profitable is your break-even ROAS.

Break-Even ROAS = 1 ÷ Gross Margin

If your gross margin is 50%, your break-even ROAS is 2x. If your margin is 25%, you need 4x just to break even. A 4x ROAS that looks impressive on a benchmark chart can still be a loss for a low-margin business, and a 2x ROAS that looks weak can be solidly profitable for a high-margin one.

Example: A product sells for $100 with $70 in costs (a 30% margin). Break-even ROAS = 1 ÷ 0.30 = 3.33x. Anything below 3.33x on that product is losing money on the ad spend alone; anything above it is genuine profit.

Calculate your own break-even ROAS before comparing your number against any industry benchmark below.

What Is a Good ROAS?

Current 2026 reports disagree substantially on blended platform averages, which is itself the main reason break-even ROAS matters more than any of these figures. The ranges below reflect that spread.

Why the range is wide: unlike CTR or CPC, ROAS depends on your product margins, average order value, and repeat purchase behavior as much as on the ad platform itself. Retargeting a warm audience routinely returns two to three times what cold prospecting does on the same platform, which alone explains a huge share of the spread you’ll see quoted across different reports.

How to Improve Your ROAS

  • Increase average order value with bundles, upsells, or free-shipping thresholds. This raises ROAS without touching ad cost
  • Shift budget toward the audiences, products, or campaigns already proving the highest ROAS rather than spreading spend evenly
  • Separate prospecting and retargeting budgets and judge each against its own realistic benchmark, not a single blended target
  • Use value-based bidding (such as Target ROAS in Google Ads) once you have enough purchase-value data flowing into the platform
  • Reduce wasted spend with tighter negative keyword lists and placement exclusions
  • Calculate your true break-even ROAS based on your margin, a 4:1 that looks “good” on a benchmark chart can still be unprofitable for a low-margin business

Frequently Asked Questions

It depends far more on your profit margin than on any industry benchmark. Blended averages range from roughly 2:1 to 6:1 on Google Ads and 1.9:1 to 2.8:1 on Meta depending on the source, but your break-even ROAS (1 divided by your gross margin) is the number that actually determines whether a given ROAS is profitable for you.

Divide the revenue a campaign generated by what you spent to generate it. For example, $2,400 in revenue from $600 in ad spend gives a 4.00x ROAS. The calculator above does this instantly, or you can use it in reverse to solve for revenue or ad spend.

ROAS = Revenue ÷ Ad Spend. To reverse it, Revenue = ROAS × Ad Spend, and Ad Spend = Revenue ÷ ROAS.

Break-even ROAS is 1 divided by your gross margin, and it tells you the exact point where ad spend stops costing you money and starts generating profit. A 30% margin business breaks even at 3.33x ROAS; a 60% margin business breaks even at 1.67x. Comparing your ROAS to an industry average tells you how you rank against other businesses; comparing it to your break-even tells you whether you’re actually making money.

ROAS only looks at revenue versus ad spend and ignores other costs like product cost and overhead. ROI (Return on Investment) factors in total cost, giving a truer picture of actual profit. A campaign can show a strong ROAS and still have a weak or negative ROI once product and fulfillment costs are included.

Use the reverse mode above: set “I want to calculate” to Revenue, enter 4 for ROAS and 2000 for Ad Spend. The calculator shows $8,000 in revenue is needed.

This is normal and widely reported. Google captures existing purchase intent (people actively searching), while Meta creates demand by showing ads to people who weren’t necessarily looking, which typically converts at a lower rate. Meta ROAS running 15 to 25 percent below Google ROAS for the same brand is a commonly cited pattern, not a sign something is broken.
