Variable Cost: Explained

What is it, how to calculate it, formula, why it's important

Hey there! Do you know what a variable cost is? I know I do! But believe me, it hasn't always been that way. Before I started working as a CFO at my company, the term was just another accounting jargon that I couldn't be bothered to understand. But now, after working with them day in and day out, I can say that they are crucial to business success. So let me help you understand what a variable cost is and why it matters.

What Is a Variable Cost?

Simply put, a variable cost is a cost that fluctuates with production, sales, or any other business activity. The more you produce or sell, the higher the variable cost becomes. And vice versa - the less you produce or sell, the lower the variable cost becomes.

Here's an example: say you run a bakery that produces cakes. The variable cost for the ingredients (flour, sugar, eggs, etc.) will change depending on the number of cakes you produce. If you produce ten cakes, your variable cost for ingredients will be higher than if you produce five cakes. Make sense?

Why Do Variable Costs Matter?

Variable costs are important because they directly affect a company's profit margin and, ultimately, its bottom line. If a company can reduce its variable costs, it can increase its profit margin. And who doesn't want more profit, right?

Let me give you another example: let's say you run a t-shirt printing business. The variable cost for each t-shirt includes the cost of the blank shirt, ink, and any other materials used to print the design. If you can reduce your variable cost (e.g., by negotiating better prices with your suppliers), you can either increase your profit margin or lower your prices to attract more customers - either way, it's a win-win situation.

Variable Costs vs. Fixed Costs

Now, you may be thinking, "okay, variable costs, got it. But what about fixed costs?"

Good question! Unlike variable costs, fixed costs remain the same regardless of production or sales volume. Examples of fixed costs include rent, salaries, and utilities. These expenses are necessary to keep the business running, so they don't change with sales or production.

So why is it important to know the difference between fixed costs and variable costs? Well, when you're trying to price your products or services, you need to take into account both fixed and variable costs. You want to make sure that the price you set covers all your costs (fixed and variable) and leaves you with a healthy profit margin.

How to Calculate Variable Costs

Now that you know what variable costs are and why they matter, you may be wondering how to calculate them. Don't worry; it's not as complicated as it sounds!

The formula for calculating variable costs is:

Variable Cost = Units Produced x Variable Cost Per Unit

Let's use the cake bakery example again. Suppose you produce ten cakes, and your variable cost for ingredients is $5 per cake. Using the formula above, your total variable cost would be:

Variable Cost = 10 x $5 = $50

See, I told you it wasn't that hard!

The Bottom Line

So there you have it - variable costs explained! I hope this article has helped you understand what variable costs are, why they matter, and how to calculate them. Remember, when it comes to running a successful business, every penny counts, so knowing your variable costs is crucial to your bottom line. Knowledge is power, and with this newfound knowledge, you're one step closer to becoming a savvy business owner. Good luck!
