Contribution margin is the amount remaining from sales revenue after deducting variable costs. It shows how much each sale contributes toward covering fixed costs and generating profit.
Contribution margin is a powerful profitability metric that helps you understand how each product, service or sale contributes to your overall business. It is calculated as Revenue minus Variable Costs. The contribution margin ratio (contribution margin divided by revenue) tells you what percentage of each sales dollar is available to cover fixed costs and contribute to profit. For example, if your product sells for $100 and has $60 in variable costs, the contribution margin is $40 (40% ratio). This means 40 cents of every dollar in revenue goes toward fixed costs and profit. Contribution margin analysis is essential for pricing decisions, product mix optimisation and break-even analysis. Products or services with higher contribution margins should generally be prioritised. SortBooks helps calculate contribution margins by accurately separating variable costs from fixed costs and providing per-product or per-service profitability analysis.
SortBooks helps with the bookkeeping behind contribution margin by connecting to your Xero account and using AI to suggest the right account for transactions sitting in catch-all accounts, learning from your own past coding. Instead of fixing contribution margin by hand, you review each suggestion, approve it, and SortBooks updates Xero, GST code included. Then ask the AI CFO about your numbers, using live Xero data.
Gross profit is your revenue minus the cost of goods sold (COGS). It shows how much money remains from sales after covering direct production or purchasing costs.
The break-even point is the level of sales at which your total revenue equals your total costs, resulting in zero profit or loss. It tells you the minimum you need to sell to cover all expenses.
Variable costs change in proportion to your business activity or sales volume. Examples include raw materials, direct labour, shipping costs and sales commissions.
Fixed costs are business expenses that remain constant regardless of your sales volume. Examples include rent, insurance premiums, salaries of permanent staff and loan repayments.
Profitability measures your business's ability to generate profit from its operations. Key metrics include gross margin, operating margin, net margin and return on equity.
