What is Average variable cost (AVC)?

Average variable cost (AVC) is like how much it costs to make one toy when you're building toys in a factory.

Imagine you have a toy factory, and every time you make a toy, you need some materials, maybe plastic, paint, or batteries. These are variable costs because they change depending on how many toys you make. If you make more toys, you use more materials; if you make fewer, you use less.

Let's say your factory makes 10 toys and uses 5 liters of paint. The average variable cost would be the total amount of paint used divided by the number of toys made. So AVC = total variable cost ÷ quantity of toys. This helps you know how much it costs to make each toy, just from the materials.

Now imagine you're making 20 toys and use 10 liters of paint, your AVC stays the same, because you’re still using 0.5 liters of paint per toy. That’s why AVC is a useful number, it helps you see if your costs are going up or down as you make more or fewer things.

If you start making even more toys and run out of paint, your AVC might go up! So, it's like keeping track of how much material each toy uses, simple and helpful.
