Find how many users you need to break even
A SaaS business breaks even at a certain number of paying users, and knowing that number is a key milestone. This calculator estimates the paying users needed to break even from your fixed costs and per-user economics.
Why the user count is the milestone
A subscription business covers its fixed costs with the contribution from each paying user, their subscription revenue minus the variable cost to serve them, so break-even is fixed costs divided by that per-user contribution. Expressing break-even as a user count, rather than a revenue figure, is powerful because user growth is what a SaaS team tracks and drives daily. Knowing you need, say, a certain number of paying users to cover costs turns the whole business into a concrete target, and reaching it is the milestone where the company stops burning cash and becomes self-sustaining.

Frequently Asked Questions
How many users do I need to break even?
Your fixed costs divided by the contribution per paying user, their subscription revenue minus the variable cost to serve them.
Why express break-even as users?
Because user growth is what a SaaS team tracks daily, so a user target is more actionable and motivating than a revenue figure.
What is per-user contribution?
A paying user’s subscription revenue minus the variable cost of serving them, which is what each user contributes toward fixed costs.
Why is reaching break-even a milestone?
Because it is the point where the company stops burning cash and becomes self-sustaining, a decisive moment for any startup.
