How it works
- Contribution per unit = −; Whole break-even units = ceil(/Contribution per unit); Units for target profit = ceil((+)/Contribution per unit)
- Worked example: 1,000/(25−15) = 100 Required pieces; Gross amount 2,500; (1,000+500)/10 = 150 Required pieces
- Supported input limits: : n ≤ 60; : 0 ≤ x ≤ 1,000,000,000,000; : 0 ≤ x ≤ 1,000,000,000,000; : 0 ≤ x ≤ 1,000,000,000,000; : 0 ≤ x ≤ 1,000,000,000,000

Assumptions and limitations
Fixed costs and target profit must cover the same period, with a constant selling price and variable cost per unit. Required units round up. Zero or negative contribution gives no finite break-even point in this model; demand and capacity are not forecast.
