How to Find Your SaaS Break-Even Point (Step-by-Step Guide + Free Calculator)

Bysoftwareexplain Joseph

Every SaaS founder reaches a point where they ask: When will my business stop burning cash and start paying for itself?
That milestone is called your break-even point—the moment when revenue equals costs.

If you don’t know your break-even, you’re flying blind. It’s not just a finance term—it’s your survival metric. Let’s break it down in plain language, show you how to calculate it, and share tools you can use right now.

👉 Try our SaaS Break-Even Calculator to model your own numbers as you read.

What Is the SaaS Break-Even Point?

Your SaaS break-even point is the number of paying customers or monthly revenue required to cover all expenses—fixed and variable.
At this point, you’re no longer losing money, but you’re not yet profitable.

Formula:

Break-even = Fixed Costs ÷ (Average Revenue per User – Variable Cost per User)
  • Fixed Costs: Salaries, rent, hosting, software licenses
  • ARPU (Average Revenue per User): What customers pay per month on average
  • Variable Costs: Support costs, cloud usage, payment fees

This simple formula helps you see how many customers you need before growth turns into profit.

How to Calculate Your Break-Even Step by Step

Step 1. List All Fixed Costs

Think of recurring expenses that don’t change with user count—salaries, infrastructure, tools.
(Use the Operating Expense Ratio Calculator to double-check your cost structure.)

Step 2. Define Your ARPU

What’s your average monthly subscription revenue per customer?
If you have multiple tiers, calculate the blended average.

Step 3. Estimate Variable Costs per Customer

Include customer support, cloud hosting, third-party API calls, and payment processor fees.
Our Cloud Cost Savings Calculator can help you trim these.

Step 4. Compute Contribution Margin

Subtract variable costs from ARPU.
Example: If ARPU is $100 and variable costs are $25, contribution margin is $75 per customer.

Step 5. Find Your Break-Even Customer Count

Plug into the formula:
If fixed costs = $75,000 and contribution margin = $75, then:

Break-even = 75,000 ÷ 75 = 1,000 customers

That means you need 1,000 paying customers to cover your monthly burn.

Example: SaaS Startup at Break-Even

Imagine a B2B SaaS startup with:

  • $120,000 in fixed monthly costs
  • $150 ARPU
  • $30 variable cost per user

Contribution margin = $120.
Break-even = 120,000 ÷ 120 = 1,000 customers.

With this insight, founders can set sales targets and predict runway more accurately.

Why Break-Even Analysis Matters for SaaS

  • Investor Confidence: Shows you know your numbers.
  • Pricing Strategy: Helps set sustainable subscription tiers.
  • Runway Planning: Extends your cash runway by knowing customer milestones.
  • Growth Decisions: Prevents scaling too early before covering baseline costs.

It’s the bridge between survival and profitability.

Advanced Break-Even Considerations

  • Churn: Losing customers pushes your break-even further away.
    Use our Churn Impact Calculator to see the effect.
  • CAC Payback: Factor in customer acquisition costs. Break-even doesn’t mean much if CAC is too high.
  • Annual Contracts vs Monthly: Annual prepayments accelerate cash break-even even if accrual profits are further out.
  • Scenario Planning: Test different ARPU or cost structures to see how your break-even shifts.

FAQs on SaaS Break-Even Point

Q: How long does it take for a SaaS startup to reach break-even?
A: It depends on burn rate, ARPU, and growth speed. Many SaaS startups aim for 18–36 months.

Q: Should I include CAC in the break-even formula?
A: Not directly. Break-even is about covering operating costs. But CAC influences how quickly you can hit break-even.

Q: How does churn affect break-even?
A: High churn means you need more new customers just to maintain revenue, delaying break-even.

Q: What’s the difference between cash break-even and accounting break-even?
A: Cash break-even considers actual money in/out. Accounting break-even includes accrual-based adjustments.
