Affiliate Income Calculator

Plug in your monthly traffic, click-through rate, conversion rate, and average commission to get a rough sense of what affiliate income could look like. These are illustrative estimates, not a guarantee.

Example: a modest content site

With 5,000 monthly visitors, a 3% click-through rate, a 2% conversion rate, and $30 average commission, that's roughly 150 clicks and 3 conversions a month - an estimated $90/month ($1,080/year). Enter your own numbers above to see your real estimate.

Methodology

Estimated clicks = traffic × click-through rate. Estimated conversions = clicks × conversion rate. Estimated monthly income = conversions × average commission, annualized by multiplying by twelve. Real-world results vary widely based on traffic quality, offer fit, and audience trust.

Data source: none - this is pure arithmetic on the numbers you enter, no third-party pricing data involved. Last reviewed: September 2026.

Frequently asked questions

How accurate is this income estimate?
It's a straightforward multiplication of the numbers you enter, not a prediction. Real results depend heavily on traffic quality, offer fit, and audience trust - factors this tool can't measure.
What's a realistic click-through rate to enter?
It varies widely by placement and content type. Check your own analytics if you already have traffic, or start conservative (1-3%) if you're estimating for a new site.
Does this account for refunds or chargebacks?
No - the estimate is based on gross conversions and commission, not net of refunds, which most affiliate programs do apply after the fact.
Why does the average commission field affect the total so much?
Because estimated income is directly proportional to it - doubling your average commission doubles the estimated income for the same traffic, click-through rate, and conversion rate.
