Complementary good

Okay kiddo, today we’re going to talk about complementary goods.

So imagine you really love pizza. Yummy! Now, what do you think goes well with a pizza? Maybe some soda, garlic bread or even some cheese dip. These things that make your pizza experience better are called complementary goods. They complement or complete each other, so when you have one, it makes you want the other.

Another example, think about toys you like to play with. If you have a toy truck, what do you think will complement it? Maybe a toy car ramp or some additional cars to go with it, right? So, these extra things that add value to your main toy are called complementary goods.

So, complementary goods are things that we use together with another product to enhance its value or usefulness. They are products that are sold together or used together to make the other product better and make our experience more enjoyable.
