ROAS Calculator

1. 01Enter spend and revenueType the ad spend and the revenue the campaign brought in.
2. 02Add margin and target (optional)Add a gross margin to base profit on gross profit and get a break-even ROAS, and a target ROAS to check against a goal.
3. 03Read ROAS, ROI, and profitThe ROAS, ROI, estimated profit, and break-even ROAS update as you type.

• Judge a campaignSee at a glance whether a campaign returns more than it costs.
• Set a break-even targetUse your margin to find the ROAS a campaign needs just to break even.
• Compare channelsPut spend and revenue from different channels on the same ROAS basis.

• A 4x ROAS1,000 of spend returning 4,000 in revenue is a ROAS of 4x (400%).
• Break-even from marginAt a 25% gross margin, the break-even ROAS is 4x, because you keep a quarter of each revenue dollar.
• Profit on marginWith a 50% margin, 4,000 revenue on 1,000 spend gives 1,000 of estimated gross profit.

ROAS = revenue / ad spend, shown as a multiple and a percentage. ROI = profit / spend x 100. When you enter a gross margin, profit is revenue x margin - spend, and the break-even ROAS is 1 / margin (for example 1 / 0.25 = 4x).

You enter spend and revenue, and optionally a gross margin and a target ROAS. The tool returns ROAS, ROAS as a percent, ROI, estimated profit, and a break-even ROAS. Without a margin, profit is simply revenue minus spend.

Use it for a single campaign or a whole channel. Enter the margin when you care about profit rather than revenue, and set a target ROAS to get a pass/fail check.

ROAS uses revenue, so a high ROAS on a thin margin can still lose money; enter the margin to see profit. It does not include overheads, returns, or lifetime value. Results are estimates to help you plan, not financial advice. Check them against your own account data before you rely on them.

What is a good ROAS?

It depends on your margin. The break-even ROAS is 1 / margin, so a 25% margin needs 4x just to break even; profitable campaigns run above that.

What is the difference between ROAS and ROI?

ROAS compares revenue to spend; ROI compares profit to spend. A campaign can have a high ROAS but a low ROI if the margin is thin.

Why enter a gross margin?

Revenue is not profit. The margin lets the tool estimate gross profit and the break-even ROAS.

Does it include returns or overheads?

No. It is a campaign-level estimate. Fold returns, fees, or overheads into the margin for a truer picture.
