Inputs and Margin

Known Inputs

Break-even analysis begins with fixed cost, unit price, and unit variable cost.

highlighted = computed this step

Fixed cost

The fixed cost is $60. Motivation: this cost is paid before any units are sold.

F=$60F=\$60
Break-even inputsThe fixed cost starts the cost line; price and variable cost set the slopes.known inputsdollarsfixed cost60unit price10unit variable cost4

Unit price

The unit price is $10. Interpretation: each sold unit adds that much revenue.

p=$10p=\$10

Unit variable cost

The unit variable cost is $4. This part grows with quantity.

Known inputs

These are assumed inputs, not estimates learned by the lesson. Break-even analysis assumes the fixed cost, unit price, and unit variable cost are known and stay constant. It does not estimate demand, capacity, taxes, or whether every unit can be sold.
