Understanding Affiliate Commission Math
Success in affiliate marketing depends on balancing three critical variables: traffic volume, conversion rates, and commission percentages. Use this calculator to determine if a specific affiliate program is worth your time or to set targets for your next campaign.
How to Calculate Affiliate Earnings
The standard formula used in this calculator is:
Total Sales: Clicks × Conversion Rate (%)
Gross Sales Volume: Total Sales × Average Order Value (AOV)
Net Commission: Gross Sales Volume × Commission Percentage
EPC: Net Commission ÷ Total Clicks
Real-World Example
Imagine you are promoting a fitness product with the following metrics:
"You send 1,000 clicks to a merchant. Their page converts at 3%. The product costs $150 and they pay a 15% commission. Your 30 sales (1,000 * 0.03) result in $4,500 in total sales. At a 15% rate, your profit is $675.00, with an EPC of $0.67."
Why Earnings Per Click (EPC) Matters
While the total commission looks great, experienced marketers focus on EPC. If Program A pays $100 per sale but converts at 0.5%, and Program B pays $20 per sale but converts at 5%, Program B is likely more profitable because the EPC is higher. This calculator helps you compare these scenarios side-by-side.
function calculateCommission() {
var clicks = parseFloat(document.getElementById('monthlyClicks').value);
var convRate = parseFloat(document.getElementById('conversionRate').value);
var aov = parseFloat(document.getElementById('avgOrderValue').value);
var commission = parseFloat(document.getElementById('commPercentage').value);
if (isNaN(clicks) || isNaN(convRate) || isNaN(aov) || isNaN(commission)) {
alert("Please enter valid numbers in all fields.");
return;
}
// Logic: Calculate total referrals
var totalSales = clicks * (convRate / 100);
// Logic: Calculate total sales volume in dollars
var grossVolume = totalSales * aov;
// Logic: Calculate the actual affiliate payout
var netPay = grossVolume * (commission / 100);
// Logic: Calculate Earnings Per Click
var epc = clicks > 0 ? (netPay / clicks) : 0;
