What Is a Break-Even Point?
Also known as Break-even, BEP, Breakeven point
A break-even point is the level of sales at which total revenue exactly covers total costs, so the business makes neither a profit nor a loss. It is calculated by dividing fixed costs by the contribution margin per unit, which is price minus variable cost. For SaaS, it is often expressed as the number of customers or MRR needed.

Break-even splits costs into two groups. Fixed costs stay roughly the same regardless of sales, such as salaries, rent and most software subscriptions. Variable costs rise with each customer, such as hosting, data fees and payment processing. Each sale leaves a contribution margin that pays down fixed costs. Once those are covered, extra sales become profit.
For SaaS companies, break-even is usually framed in customers or MRR. If each customer contributes $320 a month after variable costs and fixed costs are $120,000 a month, you need 375 customers to break even. That number turns a vague goal like profitability into a concrete sales target the whole team can track.
Break-even is a moving target. Hiring raises fixed costs, discounting lowers contribution, and churn means you have to keep replacing customers just to stay there. Founders often use break-even analysis before hiring SDRs or launching new channels, asking how many extra customers each new cost requires and whether the pipeline can realistically support it.
Break-Even Point formula
Break-even customers = Monthly fixed costs ÷ (Average revenue per customer − Variable cost per customer)
- Monthly fixed costs
- Costs that do not change with customer count, such as salaries, rent, insurance and core software.
- Average revenue per customer
- Average monthly recurring revenue per paying customer, excluding one-time fees, also called ARPA.
- Variable cost per customer
- Monthly costs that rise with each customer, such as hosting, data, support load and payment processing fees.
Worked example: A SaaS company has $120,000 in monthly fixed costs. Each customer pays $400 a month and costs $80 a month to serve. Contribution per customer is $400 − $80 = $320. Break-even = $120,000 ÷ $320 = 375 paying customers.

Break-Even Point example
A bootstrapped cold email tool has $45,000 in monthly fixed costs. Customers pay $150 a month and variable costs are $30, leaving $120 each, so break-even is 375 customers. It currently has 300. Hiring an SDR at $6,000 a month would raise break-even by 50 customers to 425, so the founder only hires once the SDR's pipeline target clearly covers that gap.
How to calculate a break-even point
List fixed costs
Add up monthly costs that stay roughly flat regardless of sales: salaries, rent, insurance, core tools and loan payments.
Find variable cost per customer
Estimate the monthly cost of serving one more customer, including hosting, data, payment fees and support time.
Calculate contribution margin
Subtract variable cost per customer from average monthly revenue per customer. This is what each customer adds toward fixed costs.
Divide fixed costs by contribution
Divide monthly fixed costs by contribution per customer. Round up, since you cannot have a fraction of a customer.
Re-check before big changes
Recalculate whenever you hire, change prices or add a new channel, so you can see how far break-even moves.
Common mistakes
- Treating all costs as fixed or all as variable, which produces a break-even point that is far too high or too low.
- Ignoring churn, since you must keep replacing lost customers just to stay at break-even each month.
- Using list price instead of the average price customers actually pay after discounts.
- Forgetting one-off upcoming costs, such as a planned hire or annual software renewal, when setting targets.
Break-Even Point FAQ
Break-even is the exact point where revenue equals costs and profit is zero. Profitability is anything above that point. A business passing break-even starts earning profit on each additional sale, as long as costs do not rise at the same time.
Divide fixed costs by the contribution margin ratio, which is contribution per customer divided by revenue per customer. With $120,000 fixed costs and an 80% contribution margin ratio, break-even revenue is $150,000 a month.
There is no standard timeline. Bootstrapped companies often aim for break-even early because they cannot rely on outside funding. Venture-backed companies may stay below break-even for years by choice while they invest in growth, as long as their unit economics hold up.
No. Break-even looks at the whole business covering all costs. CAC payback looks at a single customer earning back the cost of acquiring them. Fast CAC payback helps a company reach break-even, but the two answer different questions.
