🤝 Affiliate Marketing Commission & EPC Calculator
An affiliate commission calculator for monthly earnings, earnings per click (EPC) and revenue from your traffic, conversion rate and order value.
What Affiliate Marketing Commission & EPC Calculator Does
This calculator turns four numbers — monthly clicks, conversion rate, average order value and commission rate — into projected affiliate earnings, the number of sales behind them, and earnings per click. The monthly figure is annualized on the assumption that traffic holds.
Earnings per click is the output that matters most and the one most people ignore. Commission rate on its own tells you very little: a 4% program on a $600 product converting at 3% pays far better than a 30% program on a $25 product converting at 1%. EPC collapses rate, price and conversion into a single number you can compare across programs, and it is what affiliate networks use to rank offers for exactly that reason.
It also answers the question Google attaches to this search. If your EPC is $0.30, then $10,000 a month requires 33,334 clicks a month — not visits to your site, clicks on the affiliate link. Whether that is achievable is a traffic question rather than a commission question, and it is the honest way to size the ambition before choosing a program.
How to Use Affiliate Marketing Commission & EPC Calculator
- Input monthly link clicks and conversion rate percentage
- Enter average order value (AOV) and commission percentage
- Review projected monthly and annual affiliate revenue and EPC metric
Formula Used by Affiliate Marketing Commission & EPC Calculator
Projected earnings
sales = clicks × conversion rate; earnings = sales × AOV × commission rate
- clicks
- Clicks on your affiliate links in a month, not page views
- conversion rate
- Share of those clicks that become a purchase
- AOV
- Average order value — what the buyer spends, which may exceed the price of the item you linked
- commission rate
- Your share of that order value
Worked example
The defaults: 10,000 clicks a month, 2.5% conversion, $80 average order, 15% commission.
- Sales: 10,000 × 2.5% = 250
- Sales volume: 250 × $80 = $20,000
- Earnings: $20,000 × 15% = $3,000
Result: $3,000 a month, $36,000 a year if the traffic holds — which is the assumption doing the most work in that annual figure.
Earnings per click
EPC = earnings ÷ clicks = conversion rate × AOV × commission rate
- EPC
- Average revenue generated by one click. Independent of traffic volume, which is what makes it comparable
Worked example
The same inputs, computed both ways.
- From totals: $3,000 ÷ 10,000 = $0.300
- Directly: 0.025 × 80 × 0.15 = $0.300
Result: $0.300 per click. Note that clicks cancel out entirely — EPC is a property of the program and your audience's behavior, not of how much traffic you send.
Traffic required for an income target
clicks needed = monthly target ÷ EPC
- monthly target
- The income you are aiming at
Worked example
Targeting $10,000 a month at the default EPC of $0.300.
- 10,000 ÷ 0.300 = 33,333.3
Result: 33,334 clicks a month, every month. At a generous 5% click-through from page views that is roughly 667,000 monthly visitors — which reframes the question from "is this program good enough" to "can I build that audience".
EPC by Conversion Rate and Commission Rate — $80 Average Order
Every cell is conversion × AOV × commission. Read across to see that commission rate alone predicts very little: a 5% program converting at 5% beats a 30% program converting at 1%.
| Conversion rate | 5% commission | 10% | 15% | 20% | 30% |
|---|---|---|---|---|---|
| 1.0% | $0.040 | $0.080 | $0.120 | $0.160 | $0.240 |
| 2.0% | $0.080 | $0.160 | $0.240 | $0.320 | $0.480 |
| 2.5% | $0.100 | $0.200 | $0.300 | $0.400 | $0.600 |
| 3.0% | $0.120 | $0.240 | $0.360 | $0.480 | $0.720 |
| 5.0% | $0.200 | $0.400 | $0.600 | $0.800 | $1.200 |
Can You Make $10,000 a Month? The Clicks Required
This is the question people arrive with most often. Each row is a plausible program profile; the answer is the same arithmetic every time, target ÷ EPC.
| Program profile | EPC | Clicks needed per month |
|---|---|---|
| 1% conversion, $50 order, 5% commission | $0.025 | 400,000 |
| 2% conversion, $80 order, 10% commission | $0.160 | 62,500 |
| 2.5% conversion, $80 order, 15% commission | $0.300 | 33,334 |
| 3% conversion, $120 order, 20% commission | $0.720 | 13,889 |
| 5% conversion, $200 order, 30% commission | $3.000 | 3,334 |
What Reversals Do to the Projection
Refunds, cancellations and returned goods reverse the commission after it was credited. This calculator has no reversal input, so apply the haircut yourself — the defaults are shown here.
| Reversal rate | Monthly earnings | Effective EPC |
|---|---|---|
| 0% (what this tool reports) | $3,000.00 | $0.300 |
| 5% | $2,850.00 | $0.285 |
| 10% | $2,700.00 | $0.270 |
| 20% | $2,400.00 | $0.240 |
How to Read Your Result
Compare programs on EPC, negotiate on rate
The commission rate is the number in the pitch and the weakest predictor of income in the table above. Before switching to a higher-rate program, work out the EPC of both: a rate rise from 15% to 20% is worth a third more per click, but it is wiped out entirely if the new merchant converts at 1.8% instead of 2.5%. The only fair comparison runs all three variables together, which is what EPC does.
Average order value is not the price of what you linked
On most retail programs you are paid on the whole basket, or on everything the visitor buys within the cookie window, not just the item in your link. That makes AOV higher than the linked product's price and it is why low-rate general retail programs can still work. It cuts the other way for single-product or subscription merchants, where AOV is fixed at the price and there is no basket to expand.
The cookie window decides who gets paid
Attribution is usually last-click within a cookie window that ranges from 24 hours to 90 days depending on the program. A short window means a visitor who researches for a week and buys later earns you nothing, and it also means a coupon or cashback site that touches the visitor after you frequently takes the commission. Neither the window nor the attribution model appears in this calculation, and between two programs with identical EPC the one with the longer window is materially better.
The annual figure assumes a flat year
Multiplying a month by twelve treats traffic, conversion and commission rate as constants for a year. In practice merchants cut rates, seasonal traffic swings hard, a single algorithm update can halve referral volume, and programs close. Treat the annual number as the current run rate rather than a forecast, and rerun it when any of the four inputs actually moves.
Limitations & Accuracy Notes
- No reversal or refund rate input. Commissions reversed after a refund or cancellation are not deducted — apply the haircut from the table above yourself.
- No recurring or lifetime commission. Subscription programs that pay every month a referred customer stays need a lifetime model, not a single-sale one; some other calculators offer it and this does not.
- Flat commission rate only. Tiered programs that raise your rate with volume, and Amazon-style category rates that differ by product, have to be run once per rate.
- No network or payout fees, no minimum payout threshold, no currency conversion, and no withholding on payments to non-US affiliates.
- Conversion rate and AOV are entered, not measured. Both are the numbers most often guessed optimistically, and EPC scales directly with each of them.
- No cookie window or attribution modeling, so the calculation implicitly assumes every sale following your click is credited to you.
- Clicks means affiliate link clicks. Entering page views instead will overstate earnings by whatever your click-through rate happens to be, typically by a factor of ten or more.
