-

Do you run a shop or learn business in school? You need to know what is the difference between marginal cost and marginal revenue? These words help you pick how many things to make or sell. Marginal cost means the extra cash to make one more item. Marginal revenue means the extra cash from selling one more item. This story tells you all about them with simple steps and fun examples. It fits for bosses, shop owners, and kids in business class.

What Is Marginal Cost Definition?

Marginal cost definition is easy. It is the added money to make one extra thing. Think of costs that go up when you do more work. Like buying more paint for one more picture. Rent stays the same. That is fixed. But paint is not. That is what counts here.

Why care? It stops you from spending too much. Say you make cakes. Extra eggs and sugar cost more for one cake. If that cost is small, make more cakes. This helps shops and factories run smoothly.

It links to unit economics. That means looking at money per item. Good for new shops. See how to start one at how to start a small business.

Steps for Marginal Cost Formula

Use the marginal cost formula like this:

  1. See total cost now.
  2. Make more items. See new total cost.
  3. Take away the old cost from the new cost.
  4. Count extra items made.
  5. Divide cost change by item change.

The math is: Extra Cost / Extra Items.

Try it. You sell drinks. 100 drinks cost $100 in cups and juice. 101 drinks cost $101. Extra cost is $1. Extra drink is 1. So, $1 per drink. Sell more if you make cash from it.

In jobs like fixing cars, it means extra time for one car. Use apps to track. New bosses, learn cash tips at how to manage cash flow in a small business.

A Fun Marginal Cost Example

Here is a marginal cost example. You print books. 10 books cost $50 in paper. 11 books cost $55. Extra cost $5. Extra book 1. Cost $5 each.

But buy big paper rolls. 100 books $400. 101 $405. Now $5 still, or less with deals. Big makes it cheap. This is economics of production and revenue.

Shops like big stores use this for stock. Check Costco Business Center for buy tips. Do not add rent costs. That tricks you.

What Is Marginal Revenue Definition?

Math: Extra Cash / Extra Sold.

The food stand sells 20 pies for $100. 21 pies $105. Extra $5. Extra pie 1. $5 each. If the price is the same, it works. But deals make it less.
