Incremental Margin: Definition, Formula & Calculation (+examples)
- A business sells $100 more of a product.
- After paying for extra costs (like materials and wages), they keep $40 as profit.
- The incremental margin is 40% (because $40 profit ÷ $100 extra sales = 40%).
- Measures profitability: It helps businesses understand how profitable additional sales are.
- Focuses on Variable Costs: Fixed costs are generally excluded since they don’t change with short-term sales increases.
- Better decision making – Useful for pricing strategies, budgeting, and evaluating new investments.
- Incremental Gross profit margin = ($480,000 – $400,000) / ($1,200,000 – $1,000,000) = 40%
- Incremental Net Profit Margin = ($110,000 – $100,000) / ($1,200,000 – $1,000,000) = 5%
- Incremental Operating profit margin = ($240,000 – $200,000) / ($1,200,000 – $1,000,000) = 20%
- Incremental EBIT Margin = ($210,000 – $180,000) / ($1,200,000 – $1,000,000) = 15%
- Incremental EBITDA margin = ($270,000 – $230,000) / ($1,200,000 – $1,000,000) = 20%
