$\displaystyle \text{ROI} = \frac{\text{Net Profit}}{\text{Total Investments}} \times 100$

## Year over year growth

Measure and compare variations for revenue, conversion rates, average order size, customer lifetime value and more.

$\displaystyle \text{YOY} = \frac{\text{Sales this year}-\text{Sales last year}}{\text{Sales last year}}$

## Customer lifetime value

Understand the average value of a customer by using total profits, number of customers, and average number of years you retain a customer.

$\displaystyle \text{CLV} = \text{AVG order value} \times \text{Net profit \%} \times \text{AVG customer retention} \times \text{AVG purchases per year} \times \text{AVG customer lifecycle in years}$

## Average order value

Determine the AOV overall and for each important channel.

$\displaystyle \text{AOV} = \frac{\text{Total revenue}}{\text{Total number of orders}}$

## Conversion rate

Proportion of visits that result in purchases both overall and per channel.

$\displaystyle \text{CR} = \frac{\text{Transactions}}{\text{Visits}} \times 100$

## Customer acquisition cost

How much overall are you paying to get customers. This is not cost or conversion

$\displaystyle \text{CAC} = \frac{\text{MCC} + \text{W} + \text{S} + \text{PS} + \text{O}}{\text{CA}}$

```
MCC: Total marketing campaign costs related to acquisition
W: Wages associated with marketing and sales
S: The cost of all marketing and sales software
PS: Any additional professional services used in marketing and sales
O: Other overheads realted to marketing and sales
CA: Total customers acquired

## Search penetration index

How many visits are you getting from all search volume.

$\displaystyle \text{SPI} = \frac{\text{number of visitors}}{\text{number of searches}}$

## Customer satisfaction index

$\displaystyle \text{Customer satisfaction scale} \rightarrow \text{scale 1-5}$
