Bet you didn’t know anything about **CTRs** and **CPMs** and **CPAs** and all the CPs when you started all this – I know that my brain was blowing up from all these CPs, but in the end – it’s all about focus, right?

So, this blog will be a short one and we’ll help you with winning in this numbers maze and create some kind of a pattern for calculating if your campaigns are making money or not. So, math is kinda important here.

## Basic Understanding of Terms ðŸ¤“

**CTR** – Click through Rate, and it is measuring the success of the campaign you have started. You calculate this by dividing the number of users that clicked on an ad by the number of impressions (the number of times the ad was delivered).

**CVR** – or CR – Connversion rate (Conversion Ratio) and represents the proportion of people who took an action (click, installation, subscription etc.) and the number of impressions.

**CPM** – Cost per Mille or Cost per Thousand – In most cases in affiliate marketing this refers to the price for thousand-page impressions. For example, Adsense calculates the revenue from ads for websites based on CPM.

**CPA** – Cost per Action, or Aquisition – here the publisher gets paid only if the user completes the action, for example – installs an extension or an app.

**CPC** – Cost per Click -whenever the user clicks on an ad or a link the publisher will be paid.

## You don’t have to Be Einstein Math-wise ðŸ§

There are many formulas out there and we can help you list them and you may be able to calculate all the things that are relevant to you.

**CPM/CPC/CTR**

First you need to see if the traffic sources charge on CPC or CPM – it would be great if you could calculate both ways: If the CPM traffic source is able to give you a CPC as well or if your CPC traffic source can help you calculate your CPMs. Read this sentence once again.

FORMULA:** CPC x CTR x 10 = CPM**

*Example: Let’s assume that a traffic source is charging 1$ per click (that would be awesome right) and your CTR is 1%:*

1$ x 1 x 10 = 10$ – so your **CPM** is 10$.

FORMULA: **CPM / (CTR x 10) = CPC**

*Example: So, our CPM is 10$ and our CTR is 1%*

10$ / (1 x10) = 1 – so your **CPC** is 1$

FORMULA: **100 x No. of clicks / No. of views = CTR**

*Example: So your analytics shows that you had 20 clicks on a campaign and that 20k people reached your campaign (views)*

100 x 20 / 20 000 = 2000 / 20 000 = 0.1% – so this is your **CTR**

FORMULA: **CPM / (CPC x 10) = CTR**

*Another example: You calculated that your CPM is 10$ and that your CPC is 1$,so:*

10 / (1 x 10) = 1 = 1% – so this is your **CTR**

**CVR/EPC/CPA**

FORMULA: **(No. of Conversions / No. of page views) x 100 = CVR**

*Example*: *Let’s say you had 10 conversions and 100 people visited your webpage, so:*

(10/100) x 100 = 0.10 x 100 = 10%, so your **CVR** is 10%.

FORMULA: **(Payout x CVR / 100) = EPC**

*Example: Let’s say your payourtis 5$ and let’s assume that your CVR is 10%, so:*

5$ x 5% / 100 = 25 / 100 = 0.25$, so your **EPC** is 0.25%

FORMULA: **CPC x 100 / CVR = CPA**

*Example*: *So you saw that your CPC is 1$ and that your CVR is 10%, then:*

1 x 100 / 10 = 100 / 10 = 10, so your **CPA** is 10$.

### BONUS ðŸ™ˆ

FORMULA: **CTR x CVR x PAYOUT / 100 = eCPM**

*Example: So, your CTR is 5%, and your CVR is 10%, while your payout is 5$, so:*

5% x 10% x 5$ / 100 = 250 / 100 = 2.5%, so your **eCPM** is 2.5$

Now that you know all the formula’s, it is important that you understand that you need to pay attention to your profit and loss. If it’s going well, that is naturally profit, but if it is negative – again, naturally, loss. And you calculate that with the results of the above-mentioned formulas.

FORMULA: **(EPC – CPC) x Total Spend / CPC = LOSS**

Example: You spent 200$ on Ads, and the EPC was 0.20$ and the CPC was 0.50 $, so:

(0.20$ – 0.50$) x 200$ / 0.50$ = -0.30$ x 200$ / 0.50$ = -60$ / 0.50$ = -120

This means that you are short on 120$.

## What to Do if You Don’t Like What You See?

You can skip this if you like the numbers – but if you don’t, don’t worry – you can optimize your campaigns and then test again. This gives you the opportunity to make some changes and have a positive ROI. We have previously written a blog on what to do to optimize your campaigns – and you can read it here.

Optimize, optimize, optimize. Check your landing pages, check your CTA buttons, check your creatives, your message – question everything. Do some a/b tests and see which one converts best.

And when you do get things straight – you will see profit, and here is how you can calculate it:

FORMULA: **(eCPM – CPM) X Total Spend / CPM**

Example: So, you spent 100$ on a campain and the eCPM was 20$ while your CPM was 10$ calculate your profit like:

(20$ – 10$) x 100 / 10$ = 10$ x 100 / 10$ = 100$

And well, your profit is 100$ congrats!
