What counts as MRR?

MRR is recurring revenue normalized to one month. Monthly plans use the monthly price. Annual plans use annual contract value divided by 12.

How should churn be entered?

Use the expected customer churn for the period you are modeling. The calculator subtracts those customers before adding converted trials.

What does break-even mean here?

The helper shows how many trial signups must convert to replace the revenue lost to churn and keep projected MRR from dropping.
