What this ROAS calculator measures

This tool calculates Return on Ad Spend for campaigns by dividing tracked revenue by ad spend. It also shows net ROAS after refunds, plus profit-based results when you include fees, cost of goods, shipping, and other variable costs. Use it to compare campaign efficiency while keeping unit economics visible. Choose the same attribution window you use in reporting so comparisons remain consistent across weeks and channels for cleaner quarterly reporting cadence.

Inputs that typically move ROAS

Ad spend and revenue drive the core ratio, but small cost inputs can change decisions. Refund rate reduces net revenue, platform or payment fees reduce contribution margin, and COGS reflects product cost pressure. Many stores see payment fees around 2–4%, while COGS can range from 20–60% depending on category. If your AOV is consistent, you can model revenue as AOV multiplied by purchases for faster forecasting.

How break-even and target ROAS are estimated

Break-even ROAS is an estimate of the minimum ratio needed so profit equals zero. The calculator treats fees and COGS as proportional costs of net revenue, then adds fixed costs and ad spend. When you enter a target profit, it computes a higher target ROAS and the revenue required to hit that goal. This is useful for setting guardrails when you increase budgets, bid caps, or expand audiences.

How to interpret the KPIs

Gross ROAS is useful for quick comparisons during testing. Net ROAS helps when returns are meaningful. CPA translates spend into cost per purchase, and AOV shows revenue per purchase. Profit and profit ROAS summarize whether the campaign can scale without burning margin, especially when costs rise. If ROAS improves but CPA worsens, check whether AOV increased due to discounts, bundles, or upsells.

Using results to improve campaigns

Set a minimum ROAS threshold for pausing losers, and a target ROAS for scaling. If ROAS is high but profit is low, audit fees, COGS, refunds, and shipping. If CPA is rising, refine audiences, creative, and landing pages, and confirm tracking is accurate. Export CSV for weekly reviews, and share the PDF with stakeholders to align on targets. Recalculate after pricing changes to keep targets realistic.

FAQs

What is ROAS?

ROAS is revenue divided by ad spend. It indicates how much sales value you generate per unit of spend and helps compare campaigns using a simple efficiency ratio.

Why include refunds in the calculation?

Refunds reduce realizable revenue. Net ROAS helps you avoid scaling campaigns that look strong on gross revenue but underperform after returns and chargebacks are considered.

Does ROAS equal profit?

No. ROAS ignores costs like fees, product costs, shipping, and overhead. Use the profit and profit ROAS outputs to judge sustainability and scaling potential.

What attribution window should I use?

Use the same window used in your reporting dashboard. Mixing windows changes revenue attribution and makes week-to-week comparisons unreliable, especially during budget changes.

How do I set a realistic target ROAS?

Start from your break-even estimate, then add desired profit and safety margin. If refund rate or COGS fluctuates, set the target higher to protect cash flow.

Can I compare different objectives with this?

You can compare purchase-focused campaigns directly. For lead or traffic objectives, you need a reliable value per lead or per visit; otherwise ROAS won’t reflect downstream conversion value.
