ROAS Calculator
ROAS Calculator
Find your return on ad spend, your break-even ROAS, and whether your ad spend is actually profitable, not just performing.
How do you use this calculator?
Enter your total ad spend and the revenue that spend generated. The calculator returns your ROAS instantly. Add your gross margin to also see your break-even ROAS, the minimum return you need before that spend is actually making you money.
What is the ROAS formula?
What is break-even ROAS?
Break-even ROAS is the minimum return you need just to cover your costs, before any of that spend becomes real profit.
This is why a high ROAS on paper doesn’t always mean a profitable campaign. A 4x ROAS looks strong, but if your margin is only 15%, your break-even ROAS is 6.7, meaning that “strong” campaign is still losing money.
What is a good ROAS?
There’s no single good ROAS. It depends entirely on your margin, so use break-even ROAS as your real baseline rather than a generic number. As a general reference by channel:
| Channel | Typical ROAS range |
|---|---|
| Meta Ads | 1.8x – 3.0x |
| TikTok Ads | 1.5x – 2.5x |
| Google Search | 3.5x – 6.0x |
| Google Shopping / Performance Max | 4x – 6x |
A low-margin product often needs a ROAS of 5x or higher to be worth running. A high-margin service or subscription business can be profitable at 2x or lower. Compare your result against your own break-even ROAS above, not just these ranges.
What does a ROAS calculation look like on each platform?
The math is identical across channels, but the spend, revenue, and margin assumptions rarely are. Here’s the same $1,000 budget run through three common setups.
Meta Ads 2.8x
- Ad spend$1,000
- Revenue$2,800
- Margin35%
- Break-even2.9x
Google Search 4.6x
- Ad spend$1,000
- Revenue$4,600
- Margin35%
- Break-even2.9x
TikTok Ads 1.9x
- Ad spend$1,000
- Revenue$1,900
- Margin35%
- Break-even2.9x
At the same 35% margin, only the Meta and Google campaigns clear break-even. The TikTok campaign has a ROAS well above zero and still loses money, which is the exact gap a raw ROAS number hides and break-even ROAS catches.
How do you improve your ROAS?
Cut spend on non-converting audiences
Pull the spend report for the last 30 days and pause any ad set or keyword group with meaningful spend and no sales. This is usually the fastest ROAS gain available.
Raise average order value
A bundle, a quantity discount, or a post-purchase upsell increases revenue per ad click without spending more, which moves ROAS directly.
Fix the landing page before the ad
A slow or unclear landing page wastes clicks you already paid for. Improving conversion rate on the page is usually cheaper than trying to improve the ad itself.
Retarget warm traffic separately from cold traffic
Warm audiences convert at a lower cost and inflate blended ROAS when mixed with cold prospecting. Splitting the two shows which one is actually carrying performance.
Test creative before testing budget
Increasing spend on underperforming creative just loses money faster. Find the winning ad first, then scale the budget behind it.
Frequently asked questions
No. ROAS measures revenue per ad dollar spent. ROI measures actual profit after all costs, not just ad spend. A campaign can show a strong ROAS and still have weak or negative ROI if margins are thin or other costs are high.
The total amount spent on the ad platform for the period you’re measuring, such as Meta, Google, or TikTok spend. It does not include agency fees, creative production, or software costs unless you choose to add those in for a fuller picture.
This usually means your ROAS is above zero but below your break-even ROAS. A 3x ROAS on a 40% margin business clears break-even, but the same 3x ROAS on a 20% margin business falls short, since that business needs a 5x ROAS just to cover costs.
No. ROAS only looks at ad spend against ad revenue. It ignores product costs, shipping, staff, software, and overhead. That’s why break-even ROAS, which factors in gross margin, is a better indicator of real profitability than ROAS alone.
Weekly is enough for most active campaigns, and daily during a new product launch or a significant budget change. Margins and costs shift over time, so it’s worth rechecking your break-even ROAS whenever pricing or supplier costs change too.
