# What Is Total Contribution Margin?

Total contribution margin, or TCM, is an accounting term used to measure the profitability of a business. It is calculated by subtracting total variable costs from total revenue. It is a measure of how much a business is making on each sale it makes. This metric is important to understand when evaluating a business’s performance, as it can help to identify how much of their revenue is actually being translated into profits.

Total contribution margin is a useful tool for analyzing the overall performance of a business. It can be used to determine the profitability of a business over a specific period, as well as to compare different business models. It can also be used to identify areas of the business that may need improvement in order to increase profitability.

The total contribution margin equation is calculated by subtracting total variable costs from total revenue. Total variable costs are costs that vary in relation to the number of units sold. Examples of total variable costs include the cost of materials, labor, and shipping. Total revenue is the total amount of money the business has earned from sales.

## How to Calculate Total Contribution Margin

Calculating total contribution margin is relatively straightforward. The first step is to calculate total variable costs. This can be done by adding up the costs associated with each unit sold, such as the cost of materials, labor, and shipping. Once the total variable costs have been calculated, they must be subtracted from total revenue to get the total contribution margin.

Total contribution margin can also be calculated by subtracting total fixed costs from total revenue. Total fixed costs are costs that remain constant regardless of the number of units sold. Examples of total fixed costs include rent, insurance, and utilities. However, total variable costs are usually a more accurate measure of profitability as they are directly related to the number of units sold.

## The Significance of Total Contribution Margin

Total contribution margin provides an important insight into a business’s overall profitability. By subtracting total variable costs from total revenue, it gives a clear indication of how much a business is making on each sale it makes. This metric is especially important for businesses that have a wide range of products or services, as it can help to identify which products are the most profitable.

Total contribution margin can also be used to compare the profitability of different business models. By comparing the total contribution margin of two businesses, it can be determined which one is more profitable. This can be especially helpful for businesses that are looking to make changes to their current business model in order to increase their profitability.

## How to Use Total Contribution Margin in Decision Making

Total contribution margin can be used to inform decision making in a number of ways. It can be used to identify areas of the business that may need improvement in order to increase profitability. For example, if a business’s total contribution margin is low, it may make sense to reduce the cost of materials or labor in order to increase profits.

Total contribution margin can also be used to compare the profitability of different business models. By comparing the total contribution margin of two businesses, it can be determined which one is more profitable. This can be especially useful for businesses that are considering a change in their business model.
