Direct answer

How to interpret runway, churn and break-even

Runway shows how many months cash can sustain operations. Churn measures monthly customer loss and reduces the recurring base. Break-even happens when MRR covers expenses, including acquisition and COGS. A healthier SaaS usually aims for LTV:CAC above 3, short CAC payback and controlled burn multiple.

MRR is active monthly recurring revenue.
ARR is annualized MRR, usually MRR x 12.
Churn below 5% per month tends to be more sustainable.
Comfortable runway is usually above 12 months.

Frequently asked questions

Frequently asked questions

What is MRR?

MRR is monthly recurring revenue. In SaaS, it sums the monthly value paid by active customers.

What is the difference between MRR and ARR?

MRR looks at recurring revenue for one month. ARR annualizes it, usually by multiplying MRR by 12.

What is healthy SaaS churn?

It depends on the market, but monthly churn below 5% is usually a better signal for early-stage SaaS.

What is LTV:CAC?

It is the ratio between customer lifetime value and acquisition cost. Above 3x often indicates healthier acquisition.

How do you calculate runway?

Runway estimates how many months cash lasts considering burn, revenue, acquisition and gross margin.

What is break-even?

Break-even is the month recurring revenue covers the scenario's total expenses.

Is this an official financial forecast?

No. The simulator provides estimates for decision-making and planning, not an official financial forecast.
