Affiliate Earnings Calculator
Turn your traffic into a number. Enter your visitors, click-through rate, conversion rate, order value and commission rate to estimate your monthly and annual affiliate earnings.
Estimate Your Affiliate Earnings
Monthly sessions or page views that see your affiliate links.
Share of visitors who click an affiliate link. Typical: 1% to 5%.
Share of clickers who buy. Typical: 1% to 5%.
Average value of one completed purchase through your links.
The percentage of each sale the program pays you.
Your weakest stage caps everything: every stage multiplies, so a low click-through rate or a low conversion rate limits your payout no matter how much traffic you have. Treat this as an upper-bound estimate — cookie windows, returns and missed attribution all reduce real payouts. Estimates only; not financial advice.
How the Affiliate Funnel Works
Affiliate income is a chain of four multiplications: visitors, then clicks, then sales, then commission. Each stage keeps only a small share of the previous one, so small improvements at any stage compound into much bigger earnings. With the default values, 50,000 monthly visitors become 1,000 clicks, then 30 sales, then $225 a month.
Stage 1: Visitors see your links
Traffic is the top of the funnel. A blog post, a YouTube video or a social post puts your affiliate link in front of people. More targeted traffic beats more traffic: 5,000 visitors who are actively shopping for the product will outperform 50,000 casual browsers.
Stage 2: Visitors click (click-through rate)
Click-through rate is the share of visitors who click an affiliate link. A typical range is 1% to 5%. Clear calls to action, links placed early in a review, comparison tables and honest pros-and-cons lists all raise click-through rates. Links buried at the bottom of a long post get clicked far less.
Stage 3: Clickers buy (conversion rate)
Conversion rate is the share of clickers who complete a purchase. A typical range is 1% to 5%, and it depends heavily on what you recommend. Warm, well-matched recommendations convert far better than generic banner ads, and a trusted review of a product you actually use converts better than a roundup of products you have never tried.
Stage 4: You earn commission
Commission per sale equals the average order value multiplied by the commission rate. At a $75 order value and a 10% commission, each sale pays $7.50. The commission rate varies widely by industry, so the same traffic can be worth very different amounts depending on what you promote.
The Funnel at the Default Values
| Stage | Rate | Result |
|---|---|---|
| Monthly visitors | — | 50,000 |
| Clicks on affiliate links | 2% click-through rate | 1,000 |
| Completed sales | 3% conversion rate | 30 |
| Commission per sale | $75 × 10% | $7.50 |
| Monthly earnings | 30 sales × $7.50 | $225.00 |
| Annual earnings | $225.00 × 12 | $2,700.00 |
| Earnings per click (EPC) | $225.00 ÷ 1,000 clicks | $0.23 |
Notice the weakest-link effect: if the click-through rate fell from 2% to 1%, monthly earnings would halve to $112.50 even though nothing else changed. Fixing your weakest stage is almost always worth more than adding traffic.
Sales = clicks × purchase conversion rate
Commission per sale = average order value × commission rate
Monthly earnings = sales × commission per sale
Annual earnings = monthly earnings × 12
Earnings per click (EPC) = monthly earnings ÷ clicks
Typical Commission Rates by Industry
Commission rates are typical ranges, not guarantees — every program sets its own rate, and rates change. Use them to sanity-check your numbers before you commit to a niche.
| Industry | Typical commission | Notes |
|---|---|---|
| SaaS and software | 20% to 30% recurring | Often paid every month the customer stays subscribed. |
| E-commerce physical goods | 5% to 15% | Amazon-style programs sit at the low end; niche stores pay more. |
| Online courses and digital products | 30% to 50% | High margins mean high commissions; one sale can be worth many physical-goods sales. |
| Web hosting and tools | $50 to $200+ per sale (flat) | Often a flat bounty rather than a percentage. |
| Finance and insurance | $25 to $250+ per lead or sale | High payouts, but strict rules and slower approvals. |
How to Improve Each Stage
- More visitors: publish more content around buying-intent keywords (“best X for Y”, “X vs Y”, “X review”), and promote it where buyers already gather.
- Higher click-through rate: put links above the fold, use comparison tables, add clear buttons (“Check price”), and recommend fewer, better products instead of a wall of links.
- Higher conversion rate: only promote products you have used, show real results and screenshots, answer the objections buyers actually have, and send traffic to the exact product page, not a homepage.
- Higher commission per sale: move up the value ladder — promote higher-priced products, programs with recurring commissions, or categories with higher rates, and negotiate a better rate once you drive real volume.
Cookie Windows and Attribution: Read This Before You Trust the Number
Most affiliate programs track a click with a cookie that lasts a set number of days — commonly 30 days, sometimes 7, sometimes 90. If the buyer purchases after the cookie expires, you earn nothing. Returns and cancellations are also clawed back, and some buyers click a second affiliate’s link before buying, which reassigns the sale. The calculator’s result is therefore an upper bound: real payouts come in below it, sometimes well below it, especially for programs with short cookie windows.
Worked Example: A Small Review Blog
A blogger writes reviews of home-office gear. She gets 20,000 monthly visitors, 4% click through to the retailer, 2% of clickers buy, the average order is $120, and the program pays 8%.
| Step | Calculation | Result |
|---|---|---|
| Clicks | 20,000 × 4% | 800 |
| Sales | 800 × 2% | 16 |
| Commission per sale | $120 × 8% | $9.60 |
| Monthly earnings | 16 × $9.60 | $153.60 |
| Annual earnings | $153.60 × 12 | $1,843.20 |
Now compare: if she doubled her conversion rate to 4% by improving her reviews, monthly earnings would double to $307.20 without a single extra visitor. That is why experienced affiliates obsess over conversion, not just traffic.
