Methodology and assumptions
Starting MRR = customers × average MRR. Ending MRR = starting + new + expansion − contraction − churned. Net revenue retention (monthly) = (starting + expansion − contraction − churned) ÷ starting; gross revenue retention excludes expansion; annualized figures compound the monthly rate 12 times. SaaS quick ratio = (new + expansion) ÷ (contraction + churned). The projection holds new MRR constant and applies this month's expansion, contraction, and churn rates to each month's MRR. One-time fees are excluded.
Currency outputs are rounded to the nearest minor currency unit.
