Methodology and assumptions
ARR = MRR × 12. Projected ARR after n months = ARR × (1 + monthly growth)^n; equivalent annual growth = (1 + monthly growth)^12 − 1. Months to a target = ⌈ln(target ÷ ARR) ÷ ln(1 + growth)⌉. Constant compounding is a simplification; real growth usually decays as revenue scales. One-time revenue is excluded.
