Running a business means dealing with lots of numbers. One of the most important things to understand is your costs. Knowing how much you spend—and on what—can help you make smarter decisions and keep your business healthy.
In this blog, we’ll explain the difference between fixed, variable, and total costs. Don’t worry—we’ll keep it simple. With examples and tips, you’ll see how understanding your costs can improve your pricing, budgeting, and profits.
Fixed costs are expenses that stay the same no matter how much you produce or sell. They do not change even if your business is slow or booming.
Even if you don’t make a single product this month, you’ll still need to pay these costs.
Fixed costs are important for long-term planning. You need to make sure you have enough money coming in to cover them every month. Without a proper budget, what looks like an opportunity for growth can quickly become a financial burden. Equipment upgrades, hiring, and cash flow management. Everything needs to be accounted for.
Variable costs go up or down depending on how much you produce. These costs are tied to your activity.
If you make more products, your variable costs increase. If you make less, they drop.
Total cost is the sum of your fixed and variable costs.
Total Costs = Fixed Costs + Variable Costs
Understanding your total costs helps you:
Over time, as your business scales, total costs often shift. For example:
When you know your cost types, you can make better decisions. Here’s how it helps:
As businesses grow, fixed costs often become a smaller percentage of total costs. This is called economies of scale. For example, renting a factory costs the same, but as you make more products, that cost spreads across each unit—making each product cheaper to produce overall.

Sometimes, the best way to understand fixed and variable costs is to see how they work in real businesses. Let’s look at two simple but very different examples.
Imagine you run a factory that makes plastic containers. Every month, you pay for a large warehouse, expensive machines, and a full-time staff. These are your fixed costs—you must pay them whether you produce 10 or 10,000 containers.
To make the containers, you also need plastic, packaging, and electricity to run your machines. These are your variable costs—they go up as you make more units.
In this setup, your fixed costs are high, but your variable costs per unit are low. Once you make and sell enough containers to cover your fixed costs, your profit grows quickly with each extra container. The more you produce, the more your costs spread out, making each product cheaper to make. This is great if you expect steady or growing demand.
You don’t need to figure all this out on your own. Use smart tools to track your costs. One of the best options is using an ERP system—a type of software that helps manage operations, finances, and inventory all in one place.
Also, consider hiring a Fractional CFO—a part-time finance expert who brings deep insight without the full-time cost.
