Definition

Gross adds (meaning the total new customers or new MRR/ARR added in a period before churn) is a top-line growth input.

Formula

Gross adds = new customers acquired in the period (or new MRR/ARR before churn)

Example

If you sign 120 new customers or $80k of new ARR in a month, gross adds are 120 customers or $80k ARR.

How to use it

  • Track gross adds with churn to understand net growth drivers.
  • Use a consistent definition for what counts as a new customer.

Common mistakes

  • Counting reactivations as new adds without disclosing it.
  • Comparing gross adds across periods with different marketing intensity.

Measured as

Misused when

  • Counting reactivations as new adds without disclosing it.
  • Comparing gross adds across periods with different marketing intensity.

Operator takeaway

  • Track gross adds with churn to understand net growth drivers.
  • Use a consistent definition for what counts as a new customer.
  • Keep Gross Adds consistent by cohort, segment, and period before you use it as a decision signal in planning or reporting.
  • Interpret the metric alongside retention, margin, or payback so one ratio does not hide the real operating trade-off.

Next decision

  • Read Sales ops metrics hub: quota, pipeline, win rate, and capacity planning if the decision depends on interpretation, policy, or trade-offs beyond the raw formula.
  • Decide whether Gross Adds is a growth, retention, or efficiency signal before you set targets around it.
