Step 3) Divide your total costs by the number of new customers

Once you have decided on your time period and have summarized your total sales and marketing costs it’s time to divide them by the total number of new customers you acquired for your chosen timer period. 

As previously mentioned, once you have this figure it’s important to keep a close eye on it and start focusing on ways to improve it.
