***CPM (Cost per Thousand Impressions)***The advertising acronym

**CPM stands**for “cost per thousand impressions,” which is a measurement of how much money it costs you to reach 1,000 readers, viewers, visitors or listeners. To calculate the CPM, Stellar takes the

**cost of the influencer, divides it by the total number of impressions, then multiplies the total by 1000 (**

**CPM**= cost/impressions x 1000).

For example, if the spend for an influencer was

**$500**and the total number of impressions were

**1500**therefore the cost-per-mille was

**$300**((500/1500)*1000 = 300)

**NOTE**: By default on Stellar, impressions are estimated and correspond to the

*estimated reach*

** 1.25*based on industry standard. Actual impressions or reach - which are private data that can be shared by the influencer(s) - can be added manually at anytime on the

*Reports > Posts*section.

***CPE (Cost per Engagement)***To calculate the cost-per-engagement, Stellar simply takes your spend for a given influencer and divides it by the total number of engagement actions driven by this influencer.

For example, if the spend for an influencer was

**$500**and the total number of engagement actions were

**1500**therefore the cost-per-engagement was

**$0,3**(500/1500 = 0,3)

***CPC (Cost per Clic)***To calculate the cost-per-clic, Stellar simply takes your spend for a given influencer and divides it by the total number of clics driven by the link(s) of this influencer.

For example, if the spend for an influencer was

**$500**and the total number of clics were

**1500**therefore the cost-per-clic was

**$0,3**(500/1500 = 0,3)

**NOTE**:

*Custom tracking links*can be generated manually at anytime when creating or editing a report in the

*Tracking*block section.

***CPS (Cost per Sale)* **To calculate the cost-per-sale, Stellar simply takes your spend for a given influencer and divides it by the total number of sales generated by this influencer.

For example, if the spend for an influencer was **$500** and the total number of sales were **5** therefore the cost-per-sale was **$100 **(500/5 = 100)**NOTE**:

Actual sales - private data which comes from your own system or the brand you work with - can be added manually at anytime on the *Reports > Influencers section. *
