MRR forecasting projects your future revenue based on your current growth trajectory. It combines your monthly growth rate (new customers plus expansion) with your churn rate (lost revenue) to calculate where you will be.
Unlike revenue snapshots, forecasting shows you the path ahead. You can see if you are on track to hit milestones, when you might run out of runway, or how changes to churn could transform your trajectory.
Growth Rate - Churn Rate Current MRR x (1 + Net Rate)^months Example: $50K MRR with 8% growth and 3% churn = 5% net. After 12 months: $50K x 1.05^12 = $89.8K MRR.
Going from 5% to 7% net growth sounds small. But over 12 months, it is the difference between 1.8x and 2.25x your starting MRR. That is 25% more revenue from a 2% improvement.
Your base case is one outcome. Reality could be better or worse. Planning with three scenarios helps you prepare for multiple futures instead of being surprised.
MRR forecasting projects your future monthly recurring revenue based on current growth and churn rates. It helps you understand where your business is headed and plan accordingly. A good forecast accounts for multiple scenarios since no prediction is perfect.
Net growth rate equals your monthly growth rate minus your churn rate. Then compound it: MRR at month N = Current MRR times (1 + net growth rate) to the power of N. With $50K MRR, 8% growth, and 3% churn, your net rate is 5%. After 12 months: $50K times 1.05 to the 12th power = $89.8K.
No forecast is certain. Running multiple scenarios shows you the range of possible outcomes. Use the pessimistic case for runway planning and the optimistic case for stretch goals. The base case is your most likely path.
It depends on your stage. Early-stage companies often grow 10-20% monthly. As you scale, 5-10% monthly is strong. At $10M+ ARR, even 2-3% monthly growth is solid. The key metric is whether growth exceeds churn.
Churn is the silent killer of SaaS growth. With 8% growth and 5% churn, you net 3%. With 8% growth and 7% churn, you net only 1%. Small differences in churn create massive differences in where you end up 12 or 24 months out.
It depends entirely on your starting point and net growth rate. At $50K MRR with 5% net monthly growth, you hit $1M in about 63 months. At 10% net growth, it takes 31 months. This calculator shows you exactly when you hit any milestone.
Negative net growth means your business is shrinking. Revenue churn exceeds new revenue. This is common in early-stage products still finding market fit. The fix is either reducing churn through better retention or increasing acquisition.
Short-term forecasts (3-6 months) can be quite accurate if your growth and churn rates are stable. Longer forecasts are less reliable because rates change. Treat 12+ month projections as directional guidance, not precise predictions.
Calculators are useful. Dashboards that update automatically are better. See your actual MRR, growth rate, and forecast live.
