The VMR, or Variable Margin Rate, is an essential indicator for companies that want to analyze the profitability of their products or services. It measures the share of margin generated by each sale, after deducting variable costs. This calculation is crucial for making strategic decisions, optimizing cost management, and improving the company's overall financial performance. 

We explain how to calculate TMCV, why it is important, and how it can help you better manage your business.

What is TMCV? 

The TMCV represents the percentage of each euro of sales remaining to cover fixed costs and generate profit, after deducting variable costs. As a reminder, variable costs are those that vary directly with production or sales volume (e.g., raw materials, transportation costs). Fixed costs, on the other hand, are expenses that remain constant regardless of the volume of activity (e.g., rent, salaries). 

  

The TMCV is calculated as follows: 

 

 

Or: Margin on Variable Cost = Revenue - Variable Cost 

This formula gives a percentage that indicates the share of net margin available to cover fixed costs. 

  

Why is calculating the TMCV important? 

Calculating the TMCV is an essential step for all companies wishing to optimize their financial management. This ratio allows you to: 

  

Assess product profitability: The TMCV shows whether sales cover not only variable costs but also fixed costs. A high TMCV indicates better profitability. 

To assist with pricing: It allows sales prices to be adjusted based on variable costs and the desired margin. 

Optimize production: By identifying products with low TMCV, companies can adjust their production or reduce variable costs (source: Petite-Entreprise.net). 

In short, knowing your TMCV helps you better manage your sales, adjust your prices, and maximize your profitability. 

  

Example of TMCV calculation 

Let's take a simple example to illustrate how to calculate the TMCV: 

Revenue: €100,000 

Total variable cost: €40,000 

Variable cost margin = €100,000 - €40,000 = €60,000 

TMCV = (60,000 / 100,000) × 100 = 60% 

In this example, the TMCV is 60%. This means that 60% of revenue is used to cover fixed costs and potentially generate profit. 

  

TMCV and break-even point 

The TMCV is also essential for calculating the break-even point, which corresponds to the level of revenue needed to cover all costs (fixed and variable). The higher the TMCV, the faster the break-even point is reached. 

 

The break-even point is calculated as follows:  

   

So, if your annual fixed costs are €50,000 and your TMCV is 60%, you will need to generate a minimum turnover of €83,333 to break even (source: Eurecia).

TMCV is not only a profitability indicator, it also helps guide strategic business decisions. Here are the main advantages: 

  • Improving margins: Identify products with low TMCV to optimize profitability. 
  • Cost reduction: Identify excessive variable costs in order to reduce them, while maintaining a high TMCV. 
  • Adjusted pricing: Adjust your rates to maximize your margins while remaining competitive in the market.
