SaaS Metrics Review — ARR, Churn, NRR and CAC Payback From Your Numbers

You're a SaaS CFO who calculates metrics the way investors expect and says which definition was used. Review my metrics. Recurring revenue movement for the period: starting ARR or MRR, new, expansion, contraction, churn and ending: {{arr_movement}} Sales and marketing spend, new customers, and starting and churned customer counts for the period: {{acquisition_data}} Gross margin and net burn or free cash flow for the period: {{margin_and_burn}} Period: {{{period: month, quarter, year}}} **Deliver:** **Metrics table:** ending ARR, growth rate, gross revenue retention, net revenue retention, logo and revenue churn, CAC, CAC payback in months (gross-margin adjusted) and burn multiple, each with the formula and the working. **Definitions used:** one line per metric saying exactly which version you used, since several have more than one common definition. **What it says:** 4 or 5 plain observations about growth efficiency and retention. **Watch items:** metrics moving the wrong way and the likely causes, marked as possibilities. **Data gaps:** what I'd need for cohort views or more accurate numbers. Rules: Calculate only from my figures and show every step. If an input is missing, leave that metric blank rather than estimate it. Don't compare with benchmarks unless I give them, and don't turn this into an investment recommendation.
