Break-Even Point Calculator
Enter your fixed monthly costs, sale price and variable cost per unit; find how many units you must sell and the revenue you need to move from loss to profit. Marketplace-neutral, pure math — you enter the commission and shipping yourself.

Costs that don't change with unit sales: rent, salaries, subscriptions, fixed advertising.
Per-unit costs: product cost + commission + shipping/desi per sale. Verify the exact rates and amounts from your own seller panel.

Selling 250 units a month covers your fixed costs. Every unit beyond that adds ₺120 of profit.
Break-even = fixed costs / contribution margin per unit; the result is rounded up to a whole unit. Enter the commission and shipping inside the variable cost yourself, and verify the exact amounts from your seller panel.
What is the break-even point?
The break-even point is the sales volume at which your revenue exactly covers your costs — the line between loss and profit. Below it every month ends in the red; above it each additional unit becomes profit. Knowing this threshold is essential before launching a new product, setting a campaign price or committing to a fixed cost like rent or advertising.
How break-even is calculated
The calculation rests on splitting your costs into two groups. Fixed costs do not change with unit sales (rent, salaries, subscriptions, fixed advertising), while variable costs arise with each sale (product cost, per-sale commission, shipping/desi, packaging). The bridge between them is the contribution margin:
- Contribution margin / unit = sale price − variable cost / unit. This is what each unit contributes toward covering fixed costs.
- Break-even units = fixed costs / contribution margin. Rounded up to a whole unit, since you can't sell a fraction.
- Break-even revenue = break-even units × sale price.
A concrete example makes it clear:
| Input / measure | Value |
|---|---|
| Fixed monthly costs | 30.000 TL |
| Sale price / unit | 300 TL |
| Variable cost / unit | 180 TL |
| Contribution margin / unit | 300 − 180 = 120 TL |
| Break-even units | 30.000 / 120 = 250 |
| Break-even revenue | 250 × 300 = 75.000 TL |
So this business must sell 250 units — 75.000 TL of revenue — a month just to cover its fixed costs. Every unit beyond 250 adds 120 TL of profit. If the contribution margin is zero or negative (variable cost meets or exceeds the price), there is no break-even point at all: each sale only deepens the loss, and the price or variable cost has to change.
Using break-even on a marketplace
This tool is marketplace-neutral: it assumes no commission rate or shipping tariff, so you enter them yourself inside the variable cost. On a marketplace, the variable cost per unit is the product cost plus the per-sale commission plus the shipping/desi cost — verify the exact rates and amounts from your own seller panel. To break those deductions out per sale first, use the Trendyol profit calculator, and to work backward from a target margin to a price, see the profit margin calculator.
Frequently Asked Questions
What is the break-even point?
The break-even point is the sales level at which total revenue exactly covers total costs — where you make neither a profit nor a loss. Below it you lose money, above it you profit. It is usually expressed as the number of units you must sell and the revenue that corresponds to it.
How is the break-even point calculated?
Break-even units = fixed monthly costs / contribution margin per unit. The contribution margin is found by subtracting the variable cost per unit from the sale price (price − variable cost). For example, with 30.000 TL fixed costs, a 300 TL price and a 180 TL variable cost, the contribution margin is 120 TL; break-even units are 30.000 / 120 = 250, and break-even revenue is 250 × 300 = 75.000 TL.
What does contribution margin mean?
The contribution margin is the part of each unit sold that is left to cover fixed costs and then become profit: sale price − variable cost per unit. The contribution margin rate is that divided by the price. The higher the contribution margin, the fewer units you need to reach break-even.
What is the difference between fixed costs and variable costs?
Fixed costs don't depend on the number of units sold: rent, salaries, subscriptions, fixed advertising. Variable costs arise with each sale: product cost, per-sale commission, shipping/desi, packaging. In the break-even calculation fixed costs are entered as a single figure, while variable costs are entered per unit.
Where should I put commission and shipping?
Commission and shipping go inside the variable cost per unit, because they scale with units. So variable cost per unit = product cost + per-sale commission + shipping/desi cost. This tool is marketplace-neutral; you enter the commission rate and shipping amount yourself. Verify the exact rates and amounts from your own seller panel.
What happens if the contribution margin is zero or negative?
If the contribution margin is zero or negative, the variable cost per unit equals or exceeds the sale price, and there is no break-even point. Every unit you sell widens the loss. To be able to reach break-even you must either raise the sale price or lower the variable cost.
