Enter what a campaign cost and the commission it earned to see your real profit, ROI and revenue multiple after refunds, how much commission you need to break even, and how fast you earn your spend back.

Planning estimate only. Does not include taxes, platform fees or the value of your own time. Results from a short test can change as a campaign runs longer.
Quick answer: Take the commission you earned, subtract what the campaign cost, then divide that profit by the cost to get your ROI. For example, $200 spent to earn $650 is a $450 profit and an ROI of 225%: every $1 spent came back as $3.25.
The calculator compares what you spent with what you kept, using only the numbers you enter — no hidden averages.
Commission kept = commission earned × (1 − refund rate)
Profit = commission kept − campaign cost
ROI = profit ÷ campaign cost × 100
Revenue multiple = commission kept ÷ campaign cost
Profit margin = profit ÷ commission kept × 100
Break-even commission = campaign cost ÷ (1 − refund rate)
Days to earn spend back = campaign cost ÷ (commission kept ÷ campaign days)
Monthly profit uses 30 days. If the campaign cost nothing, ROI can’t be worked out, but profit and margin still can.
They describe the same campaign in three ways. ROI shows how hard your money worked: 225% means each $1 spent made $2.25 of profit. The revenue multiple is the simplest to share: 3.25× means you got back three and a quarter times what you spent. Profit margin shows how much of what you earned you kept: 69% of the $650 in the example.
A small campaign can have a huge ROI but tiny profit. A bigger campaign with a lower ROI might make far more money overall. Use ROI to judge efficiency, and the profit figure to judge whether a campaign is worth your time.
Example values are only placeholders. Your result is only as accurate as the numbers you put in, so use real data as soon as you have it:
| Input | Where to find it | Tip |
|---|---|---|
| Campaign cost | Your ads manager, plus invoices for tools or helpers | Include every cost tied to this campaign, not just ads. |
| Commission earned | Your affiliate dashboard (JVZoo, ClickBank, Impact, Amazon Associates) | Use tracking links so you know which sales came from this campaign. |
| Campaign length | The start and end dates of the spend | Match the dates of the cost and the commission. |
| Refund rate | Your dashboard’s refunds report | Skip it if your commission figure already has refunds taken off. |
Check each traffic source on its own. If you add Pinterest, Facebook and email together, one losing source can hide behind a winning one.
$200 spent earned $650 in commission. With no refunds that’s a $450 profit and a 225% ROI. With 10% refunds you keep $585, so the profit is $385 and ROI drops to 192.5%. To break even you’d need $222.22 in commission.
$150 on promoted pins earned $410 in 30 days. Profit: $260, an ROI of 173.3% (2.73× back). Commission came in at $13.67 a day, so the spend was earned back in about 11 days.
A $500 test over 14 days earned only $320. That’s a $180 loss and an ROI of −36%. It would need $500 in commission just to break even, so pause it and fix the offer or targeting first.
A $50 a month email tool supports a list earning $600 a month. Profit: $550, an ROI of 1,100% (12× back). That’s a strong case for keeping your email marketing going.
ROI rises when you earn more per campaign or spend less to get it. Pick the lever that’s easiest for you to move:
There’s no single target. Any ROI above 0% means the campaign made money; below 0% means it lost money. Many affiliates want a comfortable margin above break-even before scaling paid traffic, to allow for refunds, testing and their own time.
Subtract the campaign cost from the commission you kept, then divide by the cost and multiply by 100. For example, a $450 profit on $200 of spend is $450 ÷ $200 = 2.25, or 225%.
Enter 0 as the cost. ROI can’t be worked out without a cost, but the calculator still shows your profit and margin. If you pay for tools like an email service, enter those as the cost.
This calculator only counts money you spend. Your time is worth tracking too, but it’s easier to keep separate, for example by noting the hours each campaign takes.
ROAS compares revenue to ad spend (for example, 3.25×), while ROI compares profit to spend (225%). This calculator shows both: the revenue multiple is the same idea as ROAS.
No. It only changes the symbol shown. Enter all your amounts in the currency you choose.
