How to calculate net new customers
Net new customers is the logo-count counterpart to net new MRR: it nets additions against losses to show real growth in your customer base. Gross adds alone can hide a churn problem.
A month of strong new logos means little if you lost almost as many. Netting the two reveals whether the base is actually expanding or just churning and refilling.
- New - churned The formula
- Net, not gross The honest number
- Logo growth What it measures
Short answer
Net new customers is the true change in your customer count. Subtract customers churned from new customers added in the period. If you added 120 customers and lost 30, net new customers is 90. Gross additions alone overstate growth by ignoring churn, so net new customers is the honest measure of how your base is really growing.
Step by step
Count new customers added
Count the customers newly acquired in the period. This is your gross additions.
Count customers churned
Count the customers lost to cancellation in the same period.
Subtract churned from added
Net new customers equals new customers added minus customers churned. A negative result means your base shrank.
Track the components
Watch both gross adds and churn, not just the net. Two months with the same net new customers can hide very different acquisition and churn dynamics.
Worked example
In the quarter you acquired 200 new customers and lost 60 to churn. Net new customers = 200 minus 60 = 140.
If gross adds held at 200 next quarter but churn rose to 120, net new customers would fall to 80 even though acquisition was unchanged. The net figure caught a churn problem that the gross adds alone would have hidden.
How Ardovo handles it
Ardovo computes net new customers alongside gross adds and churn from live data. Rook flags when strong acquisition is being eroded by rising churn, so you see real logo growth rather than a flattering gross number.
Frequently asked questions
What is the net new customers formula?
New customers added minus customers churned in the period. Gross additions alone overstate growth by ignoring churn, so net new customers is the honest measure of how your customer base is actually growing.
Why use net new customers instead of gross additions?
Because gross adds ignore churn, so a strong acquisition month can mask heavy losses. Net new customers subtracts churn, revealing whether the base is truly expanding or just churning and refilling at the same rate.
What does negative net new customers mean?
That you lost more customers to churn than you added, so your customer base shrank in the period. It is a serious warning that churn is outpacing acquisition, even if gross additions looked healthy.
