Break-Even Calculator for Sales Units, Revenue and Profit
Enter fixed costs for one period, selling price and variable cost per unit, then the whole units you expect to sell in that same period. The threshold rounds up to a whole unit.

How to use this calculator
- Enter your values using the units shown.
- Review the result, which updates instantly.
- Check the formula and assumptions before using the number for a decision.

Formula and assumptions
Contribution per unit = price − variable cost. Break-even whole units = ceiling(fixed costs ÷ contribution). Threshold revenue = whole units × price. Planned profit = planned units × contribution − fixed costs.
03
Worked example
With fixed costs of 10,000, price 50 and variable cost 30, each unit contributes 20. Break-even is 500 units and 25,000 in revenue. Selling 600 units gives a profit of 2,000 before excluded costs and taxes.

FAQ
Frequently asked questions
Why is the sales threshold rounded upward?
A fractional unit cannot be sold in this model. Rounding up gives the first whole-unit volume that covers the entered fixed costs; revenue is calculated at that rounded volume.
What if the price does not exceed variable cost?
Sales provide no positive contribution toward fixed costs. The calculator asks you to revise the inputs rather than showing an achievable break-even threshold.
Can I use monthly or annual costs?
Either is fine if planned sales cover that same period. Do not combine yearly fixed costs with monthly unit sales unless you first convert them to matching periods.
