MRR calculator
Move the sliders to see your MRR in 6 and 12 months, when you hit a goal, and where churn caps you.
Each month: customers × (1 − churn) + new customers. The cap is new customers ÷ churn, the point where you lose as many as you gain. It's simple math on the numbers you pick, not a forecast.

Questions
How is this calculated?
Each month, customers lose the churn percentage and then gain the new ones. MRR is customers times price. There's no seasonality or price change in the math, and fractional customers carry over from month to month.
Why does it say I'll never reach my goal?
Churn removes a percentage of your customers while new signups add a fixed number. Eventually the two cancel out, at new customers divided by churn. If your goal is above that point, more months won't get you there. You need more signups, lower churn or a higher price.
Is this a forecast?
No. It's arithmetic on the numbers you pick. The defaults are just a starting point, not typical results.
