TVM can also be used for trying to make personal financial decisions as well. For instance, let's say you had $10,000 that you wanted to put aside into a savings account or a CD. Your goal is to earn $2,000 (effectively turning $10,000 into $12,000).
Let's say one option is to put your money into a 5 year CD. Try to figure out what interest rate you'd need as a guarantee in order to achieve your goal.
Also, making a decision on a loan is another example of TVM. Let's say you know you can afford a car payment of $250 a month. You know that you have decent credit and the standard car loan term is about 48-60 months. So you can assume that you could get a reasonable interest rate of 2-5%. Assuming a 4% interest rate, how much car could you afford given a payment of $250 per month for 60 months?
There are plenty of examples of how TVM can be used practically in everyday life. Let me know if this helped or not.
