A more thorough explanation:

Benefit

A benefit is a good thing that happens because of something else. It is a gain or a positive result.

• Getting a good education can be a benefit because it can lead to better job opportunities.
• Exercising regularly can be a benefit to your health because it can help you stay fit and reduce the risk of diseases.
• Receiving a bonus at work can be a benefit because it is extra money that you can use to pay bills or save for the future.

These examples illustrate how a benefit is something positive that results from a certain action or event. In the first example, getting a good education leads to better job opportunities, which is a positive outcome. In the second example, exercising regularly can help you stay healthy, which is a gain. In the third example, receiving a bonus at work is a positive result of your hard work and can be used for financial gain.
