Breakeven Calculator Guide: Find Your Break-Even Point
Every product has a moment where the money coming in finally covers the money going out — that moment is the break-even point. Below it you lose money; above it you profit. Because it turns a business into a simple 'how many units' question, it is one of the most useful numbers a new business can calculate before committing to inventory or a launch.

Fixed vs variable costs
Fixed costs stay the same regardless of sales — rent, salaries, insurance. Variable costs change with each unit — materials, packaging, shipping. Your break-even math starts by splitting costs into these two buckets, because they behave completely differently as sales grow.
Finding the break-even point
Subtract the variable cost per unit from the selling price to get the contribution margin — the amount each sale contributes to covering fixed costs. Then divide total fixed costs by that contribution margin. The result is the number of units you must sell to break even.
Using breakeven to make decisions
Once you know the break-even quantity, compare it with realistic demand: if it is far above what you can sell, the price is too low or the costs too high. The same math also sets a price floor and shows how much cushion you have before a downturn puts you in the red.
Key takeaways
- Break-even = fixed costs ÷ contribution margin per unit.
- Contribution margin is price minus variable cost.
- Fixed and variable costs behave differently as sales grow.
- Compare break-even quantity against realistic demand.
Frequently asked questions
What happens below the break-even point?
You lose money on every additional unit in that range. Selling more below breakeven widens the loss, which is why hitting it is the first profitability milestone.
How do I lower my break-even point?
Raise price, cut variable costs, or reduce fixed costs. Any of these lowers the break-even quantity; the calculator shows the effect of each change instantly.
Is break-even analysis only for new businesses?
No — established businesses use it for product launches, pricing changes, and planning how a fixed cost like new equipment gets paid back.
