GASP (Generally Accepted SaaS Principles) is an open standard for SaaS metrics. Definitions, formulas, relationships and a digital twin agents can read instead of guessing.

How many SaaS metrics does GASP define?

GASP defines nearly 300 metrics across 13 departments including Core, Sales, Marketing, Customer Success, Support, Onboarding, Product, Engineering, Finance, RevOps, People, Partnerships and Professional Services.

What is the difference between GRR and NRR?

GRR (Gross Revenue Retention) measures revenue retained from existing customers excluding expansion. It can only be 100% or lower. NRR (Net Revenue Retention) includes expansion revenue, so it can exceed 100%. Best-in-class SaaS companies target GRR above 90% and NRR above 110%.

How is the Rule of 40 calculated?

The Rule of 40 equals ARR Growth Rate (Year-over-Year) plus EBITDA Margin. A score above 40% indicates a healthy balance of growth and profitability. GASP specifies using ARR growth (not revenue growth) and EBITDA margin (not FCF margin) for consistency.
