What are substitute goods?
Substitute goods are two different products that can be used interchangeably by consumers. These goods have the same purpose and can replace one another in satisfying a consumer’s needs. When the price of one substitute good increases, consumers tend to switch to the other substitute good as a cheaper alternative
Substitute goods and complementary goods are direct competitors for each other. Substitute goods are competing products or services that serve the same purpose and are interchangeable in the eyes of consumers. The availability and price of substitute goods can have a significant impact on the demand and pricing of a particular product or service in the market.
What are complementary goods?
Complementary goods are items that, when combined, create a more valuable product than either item on its own. For example, a car requires both fuel and a driver in order to be of any use. Thus, the fuel and the driver are complementary goods, as they cannot be used alone and are both necessary for the car to function.
Complementary goods, cannot be replaced with each other as they are both required in order to get the most out of the product. However, they are items that tend to be consumed or purchased together because they are seen as necessary or beneficial to each other.
Examples of a substitute and complementary goods
Substitute goods are products that can be used to replace one another. Examples of substitute goods include coffee and tea, apples and oranges, and burgers and tacos. They have some similarities in that they offer a similar outcome or satisfaction but they differ in the exact product offered. The difference between substitute goods is that they can be used interchangeably when looking for a particular type of satisfaction.
Complementary goods, on the other hand, are products that can be used together to enhance the overall experience. Examples of complementary goods include cereal and milk, peanut butter and jelly, and ice cream and hot fudge. While these products may be different, they provide a more complete experience when they are used together. The difference between complementary goods is that they work together to create an even better experience than either product could offer on its own.
Key differences between substitute and complementary goods
The major difference between substitute and complementary goods is that substitute goods can be used in place of each other, while complementary goods require both items to be used together in order to create a greater benefit. Substitutes are considered competitors to each other, while complements are not considered competitors to each other.
Moreover, the price of one complementary good can affect the demand for the other good; if the price of one item rises, it may lead to an increase in demand for the other item.
One more difference between substitute and complementary goods is the effect of changes in the price of one good on the demand for the other. When the price of a substitute good decreases, the demand for the other good tends to decrease as well, as consumers switch to the cheaper substitute. Conversely, when the price of a complementary good decrease, the demand for the other good tends to increase, as the complementary good becomes more affordable and accessible.
Another difference is that substitute goods are typically seen as competitors, while complementary goods are seen as collaborators. Businesses that sell substitute goods often compete with each other for market share, while those that sell complementary goods can often benefit from forming partnerships or offering bundled products to customers.
In summary, substitute goods can replace each other in consumption, complementary goods are used together and can benefit from each other’s consumption.

How to determine if two goods are substitutes or complements
The primary difference between substitute goods and complementary goods is that one can be used in place of the other, while the other requires both products or services to be used together. Substitute goods are items or services that are similar in nature and can be used instead of each other. Complementary goods are items or services that work together to create a more complete product.
To determine whether two products or services are substitutes or complements, look at how they relate to each other. Are they similar enough that they could be used instead of one another? Or do they require both to be used together? Once you’ve answered these questions, you will have a better idea of whether the items or services are substitutes or complements.
To determine if two goods are substitutes or complements, there are a few key factors that can be considered:
Price: If the price of one good increases, does the demand for the other good also increase or decrease? If the demand for the other good increases, the goods are likely to be complementary, while if the demand decreases, the goods are likely to be substitutes
Usage: Are the goods typically used or consumed together or separately? If the goods are used together to satisfy a particular need or want, they are more likely to be complementary. If they are used or consumed separately to satisfy different needs or wants, they are more likely to be substitutes.
Availability: Are there many alternative goods available that can replace one of the goods? If there are many substitutes available, the goods are likely to be substitutes. If there are no or few alternatives available, the goods are more likely to be complementary.
Consumer behavior: What is the consumer’s behavior when purchasing the goods? Do they tend to buy both goods together or separately? If they tend to purchase both goods together, they are more likely to be complementary. If they tend to purchase the goods separately, they are more likely to be substituted.
