Business Break-Even Point Calculator
A break-even point is the sales volume where total revenue exactly covers fixed and variable costs, leaving $0 profit. Enter your fixed costs, price, and variable cost to see the exact number of units you must sell.

How the Break-Even Analysis Works
Break-even analysis splits costs into fixed (rent, salaries, software) and variable (materials, payment fees, shipping). Contribution margin per unit is price minus variable cost, and that margin is what each sale contributes toward fixed costs. Divide fixed costs by the contribution margin to get break-even units. Multiply that by price to express the same target as break-even revenue. This calculator also compares your current volume with the threshold and shows your current profit or loss, so you can see how far above or below break-even you are. Raising price, cutting variable cost, or trimming fixed overhead all lower the unit count you need. The math assumes a constant price and variable cost per unit, which holds for short-term decisions but weakens during heavy discounting or volume-based supplier pricing. Re-run it whenever costs change. A useful rule: every extra unit sold above break-even adds its full contribution margin to profit, so the upside accelerates once you pass the threshold.
Formula Used
Break-Even Units = Fixed Costs / (Price per Unit - Variable Cost per Unit)
Fixed costs $5,000, price $50, variable cost $30, so contribution margin is $20. Break-even = 250 units. At 300 units the business earns $1,000 profit.
When to Use This Calculator
- Setting a minimum monthly sales target for a new product.
- Checking whether a price cut still covers fixed overhead.
- Deciding if new fixed costs such as a hire or lease are affordable.
Common Mistakes
- Mixing up fixed and variable costs: Rent is fixed; materials scale with output. Misclassifying them shifts your break-even number.
- Leaving out owner pay and software subscriptions: Any recurring cost belongs in fixed costs, even if you pay it annually.
- Assuming fixed costs stay flat: Step costs (a second warehouse, extra staff) reset the calculation, so re-check at each growth stage.
Frequently Asked Questions
What is a break-even point and why is it important?
It is the unit volume or revenue where profit is exactly zero. It tells you the minimum you must sell to avoid losing money and how much cushion you have. Lower break-even points mean faster profitability and less risk during slow months.
How do I separate fixed from variable costs?
Fixed costs stay constant regardless of output, such as rent, salaries, and insurance. Variable costs rise with each unit sold, such as materials, packaging, and card fees. If a cost changes with volume, treat it as variable.
How do price increases affect the break-even point?
A higher price raises contribution margin, so you need fewer units to break even. The effect is powerful when variable costs are low. Just confirm customers still buy at the new price, or the volume gain is theoretical.
What is the formula for break-even sales volume?
Break-even units equal fixed costs divided by contribution margin, where contribution margin is price minus variable cost per unit. Multiply break-even units by price to express the same point as break-even revenue. Both describe the zero-profit point.
How does a price increase affect the break-even point?
A higher price raises contribution margin, so fewer units are needed to cover fixed costs and break-even falls. A price cut does the opposite and requires more volume, unless the lower price triggers a large enough increase in demand to offset it.
