What is ROAS?
Return on Ad Spend (ROAS) is a critical marketing metric that measures the amount of revenue your business earns for every dollar spent on advertising. Unlike Return on Investment (ROI), which considers overall business profitability, ROAS focuses specifically on the efficacy of your digital advertising campaigns.
How to Calculate ROAS
The formula for calculating ROAS is straightforward:
ROAS = Revenue Derived from Ads / Cost of Ads
For example, if you spend $1,000 on Google Ads and generate $5,000 in revenue, your ROAS is 5:1 (or 500%). This means for every dollar you spent, you made five dollars back.
Understanding the Inputs
- Total Ad Budget: The total amount of money you plan to spend or have spent on the campaign.
- Cost Per Click (CPC): The average amount you pay each time a user clicks on your ad. This determines your traffic volume based on your budget.
- Conversion Rate: The percentage of ad clicks that result in a sale or lead.
- Average Order Value (AOV): The average dollar amount a customer spends when they make a purchase on your site.
What is a "Good" ROAS?
A "good" ROAS varies by industry, profit margins, and operating costs. However, a common benchmark is a 4:1 ratio.
- Under 3:1: Generally requires optimization. You may be losing money once cost of goods sold (COGS) and other expenses are factored in.
- 4:1: Considered profitable for most e-commerce businesses.
- 5:1 or higher: Excellent performance; you should likely scale your budget.
function calculateROAS() {
// 1. Get Input Values by ID
var budgetInput = document.getElementById('adBudget').value;
var cpcInput = document.getElementById('cpc').value;
var convRateInput = document.getElementById('conversionRate').value;
var aovInput = document.getElementById('aov').value;
// 2. Validate Inputs (Check for empty or non-numeric)
if (budgetInput === "" || cpcInput === "" || convRateInput === "" || aovInput === "") {
alert("Please fill in all fields to calculate your ROAS.");
return;
}
// 3. Parse floats
var budget = parseFloat(budgetInput);
var cpc = parseFloat(cpcInput);
var convRate = parseFloat(convRateInput);
var aov = parseFloat(aovInput);
// 4. Edge Case Handling (Division by zero)
if (cpc <= 0) {
alert("CPC must be greater than 0.");
return;
}
if (budget < 0 || convRate < 0 || aov 0) {
roas = revenue / budget;
}
// Calculate Net Profit (Revenue – Budget)
// Note: This is gross profit on ad spend, not accounting for COGS
var profit = revenue – budget;
// Calculate ROI % ((Revenue – Budget) / Budget) * 100
var roi = 0;
if (budget > 0) {
roi = ((revenue – budget) / budget) * 100;
}
// 6. Update HTML Results
document.getElementById('roasValue').innerHTML = roas.toFixed(2) + "x";
// Formatting numbers as currency USD
var currencyFormatter = new Intl.NumberFormat('en-US', {
style: 'currency',
currency: 'USD',
});
document.getElementById('totalRevenue').innerHTML = currencyFormatter.format(revenue);
document.getElementById('netProfit').innerHTML = currencyFormatter.format(profit);
// Formatting standard numbers
document.getElementById('totalClicks').innerHTML = new Intl.NumberFormat('en-US').format(clicks);
document.getElementById('totalConversions').innerHTML = new Intl.NumberFormat('en-US').format(conversions);
document.getElementById('roiValue').innerHTML = roi.toFixed(2) + "%";
// 7. Dynamic Styling for ROAS
var roasEl = document.querySelector('.big-result .value');
if(roas = 2 && roas < 4) {
roasEl.style.color = "#f1c40f"; // Yellow
} else {
roasEl.style.color = "#2ecc71"; // Green
}
