Sales Metrics Calculator

HubSpot Free Beginner

A plug-and-play spreadsheet for calculating win rate, average deal size, and churn from your own numbers. Use it to actually run the math from our short answer, closed-won divided by total closed, and see whether you are really over that ~20 percent bar before you hire.

  • Win rate = deals closed-won divided by total deals closed (won plus lost)
  • Track win rate alongside average deal size, it changes what the number means
  • A spreadsheet built for this is faster and less error-prone than tracking it ad hoc
