How to Use the Affiliate Marketing Profit Calculator
Success in affiliate marketing depends on understanding your unit economics. This calculator helps you determine whether your current paid traffic campaign (like Facebook Ads, Google Ads, or Native Ads) is profitable or if you need to optimize your conversion rates.
Understanding Key Affiliate Metrics
Total Traffic: The number of unique clicks hitting your affiliate bridge page or direct offer link.
Conversion Rate: The percentage of those clicks that result in a successful commission-generating action.
Commission per Sale: The flat dollar amount you receive for every referral.
Cost Per Click (CPC): The average amount you pay the ad platform for every visitor sent to the offer.
The Math Behind Your Profit
Our calculator uses the following logic to determine your bottom line:
Revenue Calculation: (Clicks × Conversion Rate %) × Commission per Sale.
Expense Calculation: Clicks × CPC.
Net Profit: Revenue – Expenses.
ROI (Return on Investment): (Net Profit ÷ Total Expenses) × 100.
Example Scenario
Imagine you are promoting a fitness supplement. You send 2,000 clicks via Instagram Ads. Your CPC is $0.40, meaning you spent $800. If your conversion rate is 3%, you generated 60 sales. At a $50 commission per sale, your gross revenue is $3,000. Your net profit would be $2,200 with a massive 275% ROI.
Pro Tip: Always aim for an EPC (Earnings Per Click) higher than your CPC. If your EPC is $1.50 and your CPC is $0.50, you are essentially printing money.
