Reading your MRR forecast

Updated July 18, 2026

The MRR view shows your recurring revenue month by month for the full 36-month forecast. It is the clearest picture of how your top line grows.

What you see

  • MRR by plan tier — recurring revenue broken out by pricing plan, so you can see which tier drives growth.
  • New customers — customers acquired each month from your funnel.
  • Churned customers — customers lost each month based on your churn assumptions.
  • Expansion revenue — extra revenue from upgrades and add-on modules.
  • ARR — the annualized run-rate (MRR × 12).

The MRR waterfall

Each month’s ending MRR is built from the month before:

Starting MRR + New + Expansion − Churn = Ending MRR

This is the MRR waterfall. It shows not just how much you grow, but why — how much comes from new customers versus expanding existing ones, and how much churn drags against it.

What to look for

  • Is growth coming from new logos or expansion? Healthy SaaS increasingly grows from expansion as it matures.
  • How much is churn costing you? If churn is eating a large share of new MRR, retention is your highest-leverage fix, not acquisition.
  • Which tier carries the model? If one tier dominates, your forecast is sensitive to its assumptions.
The MRR waterfall is the number investors probe first. If new and churned MRR are close, your net growth is fragile — worth stress-testing in what-if mode.
