Affiliate marketing is one of the most accessible ways to generate passive income online. By promoting products you believe in and earning commissions on sales, you can build a revenue stream that grows with your audience. The key metrics are traffic volume, click-through rate (how many visitors click your affiliate links), conversion rate (how many clicks become sales), and commission per sale. This calculator helps you project your affiliate income and understand which levers to pull to grow it.

計算式と具体例

Monthly Clicks = Monthly Visitors × (CTR ÷ 100):

Monthly Conversions = Monthly Clicks × (Conversion Rate ÷ 100).

Monthly Revenue = Conversions × Average Commission.

Annual Revenue = Monthly × 12.

Cookie duration affects how long after a click you earn the commission - longer cookies = more attributed sales..
