What is a Good ROAS?

There is no single “good” Return on Ad Spend — it depends on your profit margin, attribution window and channel. As a rule of thumb, a minimum of 4:1 (400%) is the break-even point for a typical retail business: at a ~25% net margin you need roughly $4 in revenue for every $1 of ad spend just to cover product and advertising costs. High-margin or owned-audience channels can be profitable well below that, while low-margin products need much more. The ranges below are typical targets by channel for businesses running paid acquisition.

ChannelGood ROAS rangeNotes
Google Shopping4–8:1Product-led intent; scales with feed quality and margin.
Facebook / Instagram (Meta)3–5:1Interest & lookalike prospecting; lower intent, broader reach.
Google Search5–10:1High purchase intent; brand + bottom-funnel terms perform best.
Email marketing10–40:1Owned audience, near-zero media cost — highest ROAS channel.

Break-even floor ≈ 4:1 for a typical blended retail margin. Your true break-even ROAS = 1 ÷ gross margin (e.g. a 50% margin breaks even at 2:1).

ROAS vs ROI — What’s the Difference?

ROAS and ROI are often confused but answer different questions. ROAS (Return on Ad Spend) measures only revenue against advertising cost — it tells you how efficiently a campaign converts media budget into top-line sales. It ignores product costs, shipping, payment fees and overheads. ROI (Return on Investment) measures profit against the total cost of doing business, so it reflects whether you actually made money. A campaign can show a strong 5:1 ROAS yet a negative ROI if your margins are thin. Use ROAS to optimise and compare campaigns day-to-day; use ROI to judge whether the whole effort is profitable.

Target ROAS Calculator

Work out the ROAS you actually need to hit before launching a campaign. Enter your selling price, product cost and the net profit margin you want to keep — the tool returns your break-even ROAS, your target ROAS, and the maximum you can afford to pay per sale (target CPA).

Break-even ROAS = 1 ÷ gross margin. Target ROAS = 1 ÷ (gross margin − desired net margin). Target CPA = price ÷ target ROAS. Estimates only — not financial advice.

For e-commerce, 3-4x is average, 5-7x is good, and 8x+ is excellent. For lead generation, 10-20x is common because leads convert at higher values. For brand awareness campaigns, ROAS is less relevant than CPM and reach metrics.
ROAS only considers ad spend vs. revenue from ads. ROI considers all costs including COGS, overheads, and other expenses.

About the ROAS Calculator

A ROAS Calculator Australia helps businesses measure the return on their advertising spend by comparing revenue generated against ad costs. ROAS — Return on Ad Spend — is the most important metric for Australian digital marketers running paid campaigns across Google, Meta, TikTok, or any other platform. It answers a simple but critical question: for every dollar you spend on ads, how many dollars in revenue do you get back? With Australian businesses spending over $15 billion on digital advertising in 2025, measuring ROAS accurately separates profitable campaigns from vanity metrics. This calculator takes your total ad spend and total revenue attributed to those ads, then instantly computes your ROAS ratio and percentage return. Whether you run a small cafe in Hobart boosting posts on Facebook or a national retailer managing complex multi-channel campaigns from Sydney, ROAS is your north star metric for advertising profitability.

What is the ROAS Calculator?

The ROAS Calculator is a straightforward financial tool that computes your return on ad spend using two key inputs: total revenue generated from ad campaigns and total ad spend. The formula is simple: ROAS = Revenue ÷ Ad Spend. A ROAS of 4.0 means you earn $4 for every $1 spent on advertising. However, context matters significantly. For Australian businesses, a "good" ROAS varies by industry, margin, and business model. A low-margin grocery delivery service might need a 8x ROAS to break even, while a high-margin software company might be profitable at 2x ROAS. The calculator addresses this by also including a break-even ROAS comparison: you input your gross margin percentage, and the tool tells you whether your ROAS is actually profitable after product costs. It calculates your net profit (revenue minus COGS minus ad spend) and your net profit margin. The calculator supports both single-campaign analysis and aggregated reporting across all campaigns. It displays results as both a ratio (e.g., 3.5x) and a percentage (e.g., 250% return), giving you flexible ways to communicate performance to stakeholders, agency partners, or investors.

How to Use This Calculator

  1. 1Enter Total Revenue from Ads: Input the total revenue in AUD attributed to your advertising campaigns over the selected period. Use your platform's conversion tracking or Google Analytics 4 attribution data.
  2. 2Enter Total Ad Spend: Input your total advertising spend in AUD across all platforms for the same period, including agency fees and platform costs.
  3. 3(Optional) Enter Gross Margin Percentage: Input your gross profit margin as a percentage to see your net profit after COGS. For example, if you sell at $100 with $40 COGS, enter 60%.
  4. 4Select Attribution Window: Choose from 1-day click, 7-day click, or 28-day click window. This affects how revenue is attributed to ad clicks, especially for longer sales cycles.
  5. 5Click Calculate: The tool displays ROAS ratio, ROAS percentage, net profit after COGS and ad spend, net profit margin, break-even ROAS based on your margin, and a performance rating from Poor to Excellent based on Australian industry benchmarks.

Worked Australian Example

Practical Example

Wollongong-based skincare brand Coastal Glow runs a month-long Meta Ads campaign for their vitamin C serum. They spend $8,500 on ads and generate $34,000 in revenue directly attributed to Meta within the 7-day click window. Their gross margin is 68% ($3,000 selling price minus $960 COGS = $2,040 gross profit per unit, but their average order value is $65 with $20.80 COGS). Using the ROAS Calculator, they enter $34,000 revenue, $8,500 ad spend, and 68% gross margin. The calculator shows a ROAS of 4.0x (300% return). Net profit after COGS and ad spend is $14,620 ($34,000 × 0.68 − $8,500). The break-even ROAS at 68% margin is 1.47x — well below their 4.0x. Their campaign is strongly profitable. However, the calculator also shows that if their margin drops to 50% (e.g., during a sale), break-even ROAS rises to 2.0x, and their net profit drops to $8,500. This insight helps Coastal Glow plan promotions carefully, knowing that discounting too deeply could erase their ad profit even at the same ROAS.

The calculator uses pre-GST ad spend figures. Meta and Google charge GST on top of your spend. For accurate ROAS, either add GST to your spend input or use the pre-GST figures consistently.
