Coffee Cart Break-Even Chart

Harbor Coffee Cart sells drinks for $4.50, with an estimated variable cost of $1.20 per drink and $3,300 in monthly fixed costs. The revenue and total-cost lines meet around 1,000 drinks, which is the expected break-even volume for these assumptions. Every drink sold above that point contributes toward profit, provided prices and variable costs remain stable. Use this as a planning model, not as a guarantee. Seasonal demand, wastage, discounts, and labour changes can move the result. Update the inputs before each monthly planning cycle and compare the model with actual sales after the month closes. Review the underlying definitions and totals before using this view to make an operational decision.
