Here: subscription + expansion − churn on the three inputs. Example: $100k + $20k − $5k = $115k ARR (the defaults). Three presets ship with the tool (SaaS Startup, Enterprise, Hypergrowth) with indigo/emerald/red bars. Every dollar must sit in exactly one bucket.
ARR is contracted run-rate; revenue is recognized cash. A $120k annual deal signed in December adds $120k ARR immediately but ~$10k December revenue. Investors value the ARR; accountants audit the revenue.
No — only the next 12 months count toward ARR. A 3-year $360k deal contributes $120k ARR, not $360k. Counting full TCV as ARR is the classic fundraise-inflation error.
New ARR (new logos + expansion) shows sales output; net new subtracts churn for the growth truth. A team adding $300k while losing $280k grew $20k — celebrate the former, manage the latter.
