ROAS Calculator

How to use this calculator

1. Enter the revenue attributable to the campaign or channel.
2. Enter the ad spend for the same period.
3. Review ROAS as a multiple and percentage to judge performance vs target.

Inputs explained

Revenue

Attributed revenue for the ads/campaign over the measured window.

Ad spend

Total spend on the ads for the same window; include fees if you want net ROAS.

When to use it

• Checking if a campaign meets break-even or target ROAS.
• Comparing channels (search vs social) on the same revenue window.
• Reporting quick performance to stakeholders without full LTV models.

Tips & cautions

• Match attribution window for both revenue and spend to avoid skew.
• Use gross revenue for a top-line ROAS; subtract COGS/fees if you prefer net ROAS.
• Set a target ROAS based on your margins so you know the minimum acceptable number.
• No attribution modeling—assumes revenue entered is already attributed to the spend.
• Does not factor product margins, refunds, or LTV unless you adjust revenue for them.
• Single-period snapshot; does not model payback time for subscription/LTV cohorts.

FAQs

What is a good ROAS?

It depends on your margins. A higher-margin product might work at 2–3 ROAS; low margins may need 4–6+.

Does ROAS include cost of goods sold?

Not by default. ROAS is revenue ÷ ad spend. Use profit or ROI if you want to include COGS and fees.

How is ROAS different from ROI?

ROAS ignores product costs and only compares revenue to ad spend. ROI considers all costs and profit.

What if ad spend is zero?

ROAS would be undefined; the calculator returns 0. Enter actual spend to see a meaningful number.

Should I use gross or net revenue?

Use the same revenue definition you target internally. If you care about profitability, subtract refunds and fees first.
