What is a Gross Margin Bridge?

A gross margin bridge provides a step-by-step analysis of the changes in gross margin between two periods. It explains how factors such as price, volume, cost of goods sold (COGS), and product mix have influenced the overall gross margin. By creating a bridge, businesses gain insights into which areas require attention to improve profitability.

Key Components of a Gross Margin Bridge

A typical gross margin bridge includes the following components:

  • Beginning Gross Margin: The starting point, which is the gross margin from the previous period or the budgeted gross margin.
  • Price Variance: The impact of changes in selling prices on the gross margin. It is calculated by multiplying the change in price by the current period's sales volume.
  • Volume Variance: The impact of changes in sales volume on the gross margin. It is calculated by multiplying the change in volume by the previous period's gross margin per unit.
  • Cost Variance: The impact of changes in the cost of goods sold (COGS) on the gross margin.
  • Mix Variance: The impact of changes in the proportion of different products or services sold. It reflects how the shift in sales mix affects the overall gross margin.
  • Ending Gross Margin: The final gross margin after all variances have been accounted for.

Steps to Construct a Gross Margin Bridge

  1. Gather Data: Collect relevant financial data, including sales revenue, COGS, sales volume, and prices for both periods being compared.
  2. Calculate Beginning and Ending Gross Margin: Determine the gross margin for both the initial and final periods.
  3. Calculate Price Variance: Multiply the change in price by the current period's sales volume.
  4. Calculate Volume Variance: Multiply the change in volume by the initial period's gross margin per unit.
  5. Calculate Mix Variance: Analyze the changes in the sales mix and determine the impact on gross margin.
  6. Analyze and Interpret Results: Review each variance component and identify key drivers of change.
