Quick Start Guide

  1. Enter Ad Spend: Input the total amount spent on the advertising campaign.
  2. Enter Revenue: Input the total revenue generated from your advertising campaign.
  3. Enter Gross Margin: Optionally tick Enable Break-Even Analysis and enter your gross margin.
  4. View ROAS: See your ROAS ratio (e.g., 4x means $4 revenue per $1 spent).
  5. View Break-Even ROAS: See the minimum ROAS needed to be profitable given your margin.
  6. Export Analysis: Export your ROAS analysis as JSON, CSV or PDF.

Understanding ROAS

ROAS measures ad efficiency, not profit

ROAS is revenue divided by ad spend — it tells you how much revenue each ad dollar generates, but revenue is not profit. A 5x ROAS on a low-margin product can still lose money once cost of goods, shipping, and returns are factored in. That is why ROAS is usually read alongside a margin figure, not on its own.

Why break-even ROAS matters

Tick Enable Break-Even Analysis and enter your gross margin, and this calculator computes your break-even ROAS — the minimum ROAS needed just to cover the cost of goods sold (Break-Even ROAS = 1 ÷ Gross Margin). If your actual ROAS is below that number, the campaign is losing money even though it is generating revenue.

Reading the ad-spend scaling chart

The chart shows how revenue and profit would scale if you spent more or less at this same ROAS. Because profit is proportional to ad spend at a fixed rate, this campaign is either profitable at every spend level or unprofitable at every level — there is no single "break-even spend amount" to look for; use the break-even ROAS figure above instead.

What this calculator does not cover

This models ad spend and revenue at a single point in time — it does not account for attribution windows, multi-touch conversion paths, or costs beyond cost of goods sold (fulfillment, returns, overhead). For overall business profitability rather than ad efficiency, see the ROI Calculator.

Common Use Cases

Campaign Analysis: evaluate profitability from spend vs attributed revenue and compare campaign cohorts consistently.

Budget Allocation: shift spend toward stronger ROAS channels and validate target thresholds before scaling.

Profitability Checks: use break-even ROAS against your gross margin to detect underperforming campaigns early.

Platform Comparison: benchmark ROAS across Google, Meta, and other channels, then export summaries for stakeholder reporting.

Frequently Asked Questions

ROAS (Return on Ad Spend) measures gross revenue explicitly from ads vs. ad cost. ROI considers total profit (after all expenses) vs. total investment. ROAS looks at ad efficiency; ROI looks at business profitability.
There's no single good ROAS — it depends entirely on your gross margin. A 4:1 ROAS is often cited as a rough rule of thumb across Google, Meta, and TikTok ad campaigns alike, but the number that actually matters is your break-even ROAS (1 ÷ gross margin): anything above that is profitable, anything below it is a loss regardless of how good the ROAS looks. Tick Enable Break-Even Analysis and enter your gross margin to see your specific break-even target.
Break-even ROAS = 1 / Gross Margin. If your gross margin is 40% (0.40), your break-even ROAS is 2.5 — meaning you need $2.50 in revenue for every $1 spent on ads just to cover product cost. Tick Enable Break-Even Analysis and enter your gross margin to find your specific break-even target.
ROAS alone does not tell you if you are profitable. A 3:1 ROAS on a 50% margin product is very profitable, but the same ROAS on a 20% margin product loses money. Use the break-even ROAS feature to find the minimum ROAS needed to stay profitable given your margin.
