Discounting is a financial principle that calculates the present value of money to be received in the future.

Present Value is calculated using a discount rate, which takes into account the interest rate, inflation, and risk.

Consider John deciding whether to take two thousand dollars now or a year later from his father.

John decides which option is better using the concept of discounting. He applies a five percent discount rate, reflecting potential earnings if the money were invested.

The present value of two thousand dollars received a year later is approximately one thousand nine hundred and five dollars.

This means at a five percent discount rate, choosing two thousand dollars a year from now is the same as receiving approximately one thousand nine hundred and five dollars today.

John finds it financially beneficial to take two thousand dollars now instead of waiting for one year.

The example reflects the concept of the time value of money, suggesting that having money now is preferable. This is because it can be invested to grow and potentially be worth more than the same amount received in the future.
