Break-even units = Fixed Costs / (Price − Variable Cost)
At break-even, total profit is zero: Revenue − Variable Costs − Fixed Costs = 0. Rearranging gives volume in units.
A product sells for $20. Variable cost is $8. Fixed costs are $60,000. What volume is needed to break even?
Break-even = 60,000 / (20 − 8) = 5,000 units
Higher price or lower variable cost lowers break-even units. Use this to compare pricing or efficiency options during cases.
