    Commission Calculator

    Calculate your earnings from affiliate sales.

    Formula:

    Commission = Sale Amount × (Commission Rate ÷ 100)

    Earnings Per Click (EPC)

    Calculate how much you earn on average per click.

    Why EPC Matters:

    EPC helps you understand the value of your traffic and compare different offers/campaigns regardless of click volume.

    Conversion Rate & Earnings

    Analyze your conversion performance and projected earnings.

    Typical Conversion Rates:

    Physical products: 1-3% | Digital products: 2-5% | High-ticket: 0.5-2%

    Program Comparison

    Compare two affiliate programs to find the most profitable one.

    Affiliate Marketing Tips

    • • Focus on EPC over commission rate alone - a 10% commission with 5% conversion beats 50% with 0.5%
    • • Track everything - use sub-IDs to understand which traffic sources convert best
    • • Recurring commissions build passive income - prioritize subscription-based products
    • • Cookie duration matters - longer cookies (60-90 days) increase attribution

    What is an affiliate marketing calculator?

    An affiliate marketing calculator helps you estimate affiliate earnings and compare programs based on the metrics that actually drive profit: commission per sale, conversion rate, and earnings per click (EPC). It is especially useful when you want to choose between offers or decide whether a traffic source is worth scaling.

    Interpretation notes

    • For paid traffic, compare EPC against your cost per click to estimate margin.
