The Sum of Money

The sum of money is an amount that represents the total value of an asset. It is calculated as the sum of the principal and the interest that will be earned over a specific time period. When it comes to investments, the value of money changes over time due to inflation and other factors. The time value of money is an important concept to understand when evaluating investment opportunities or loan transaction options.

Calculating the future value of a single sum of money gives you an idea of how much that amount will be worth at a given point in time, using a formula that considers the number of compounding periods, the expected rate of interest and the length of the term. This is the opposite of figuring out the present value of a single sum, which starts with a smaller figure and grows over time through the magic of compounding interest.

In law, a sum certain is a predetermined amount that is explicitly stated in a contract or negotiable instrument. Having a sum certain removes room for ambiguity, and makes it easier to understand the value of the contract or security.

For example, say you want to know how much you need to save today at 4 percent if you hope to have $200,000 available three years from now. Using the future value table, you can see that you'll need to invest $100,000 today to get that much at a later date.סכו״ם כסף
