Understanding Your Sales Results
Gross Profit is revenue minus total costs — it tells you how much money the business made before tax. Net Profit deducts tax from gross profit to give the true bottom-line earnings. Profit Margin expresses net profit as a percentage of revenue — it is one of the most important metrics for comparing business performance over time or across competitors.
In Revenue mode, the Gross Revenue figure includes any discount reduction from the list price. The Gross Profit in this mode is revenue minus the cost of goods sold, reflecting the direct profitability of each unit at the given volume and price point.
In Break-Even mode, the Contribution Margin per unit is what each sale contributes toward paying off fixed costs. The break-even unit count is the minimum sales volume at which the business neither profits nor loses. Any sales above break-even are pure profit at the contribution margin rate.
Key Formulas
Gross Profit = Revenue − Total Costs
Net Profit = Gross Profit × (1 − Tax Rate / 100)
Profit Margin = Net Profit ÷ Revenue × 100
Break-Even Units = Fixed Costs ÷ (Price − Variable Cost per Unit)
The break-even formula denominator — Price minus Variable Cost — is the contribution margin per unit. It represents how much money each unit sale contributes toward covering the fixed overhead. This is one of the most actionable numbers in business planning: increase it by raising prices or cutting variable costs, and break-even comes sooner.
