Success in affiliate marketing is a numbers game. To build a sustainable online business, you need to understand the relationship between your traffic, how well that traffic converts, and the value of the products you are promoting. This calculator helps you forecast your monthly revenue based on standard industry metrics.
Key Metrics Explained
Monthly Visitors: The total number of unique clicks or visitors you send to the merchant's site via your affiliate links.
Conversion Rate: The percentage of those visitors who actually complete a purchase. The industry average varies, but typically ranges between 1% and 5%.
Average Order Value (AOV): The average amount a customer spends when they buy through your link.
Commission Rate: The percentage of the sale price that the merchant pays you. This can range from 1% (Amazon Associates) to 50%+ for digital products.
EPC (Earnings Per Click): A critical metric that tells you how much every single click you generate is worth. Formula: Total Commission / Total Clicks.
Example Calculation
Imagine you run a tech blog with 10,000 monthly visitors clicking your links. If your conversion rate is 3%, you generate 300 sales. If the Average Order Value is $100 and your commission is 5%, your total monthly earnings would be $1,500. This results in an EPC of $0.15.
How to Increase Your Affiliate Income
If you want to boost your results without increasing traffic, focus on two levers: Conversion Rate and AOV. You can improve conversion rates by writing better product reviews and using clearer "Call to Action" buttons. To increase AOV, promote higher-ticket items or products that naturally lead to "bundle" purchases.
function calculateAffiliateIncome() {
var traffic = parseFloat(document.getElementById('traffic').value);
var convRate = parseFloat(document.getElementById('conversion').value) / 100;
var aov = parseFloat(document.getElementById('aov').value);
var commRate = parseFloat(document.getElementById('commRate').value) / 100;
if (isNaN(traffic) || isNaN(convRate) || isNaN(aov) || isNaN(commRate)) {
alert("Please enter valid numbers in all fields.");
return;
}
// Logic
var totalSales = traffic * convRate;
var totalRevenue = totalSales * aov;
var totalCommission = totalRevenue * commRate;
var epc = traffic > 0 ? totalCommission / traffic : 0;
// Display results
document.getElementById('resSales').innerText = totalSales.toFixed(0);
document.getElementById('resRevenue').innerText = '$' + totalRevenue.toLocaleString(undefined, {minimumFractionDigits: 2, maximumFractionDigits: 2});
document.getElementById('resCommission').innerText = '$' + totalCommission.toLocaleString(undefined, {minimumFractionDigits: 2, maximumFractionDigits: 2});
document.getElementById('resEPC').innerText = '$' + epc.toLocaleString(undefined, {minimumFractionDigits: 2, maximumFractionDigits: 2});
document.getElementById('results').style.display = 'block';
