It can relate to anything that correctly applies the time value of money concepts we have studied and solves for one or more of the following: PV, FV, Annuity PMT, r or n. Here are some examples:

• Is there a car you want to lease and you would like to figure out the lease payments? Or how about you know the down payment and monthly lease payments, and you want to know what interest rate is incorporated into the lease?
• Do you want to buy a new or used car and plan to finance it with an auto loan? Do you want to determine how much your monthly payments will be based on the expected interest rate on the loan? Or do you want to know the maximum price you can afford to pay?
• Are you saving up for a new iPhone and want to know how much you will have to put aside each week or month to have enough to pay for it, or how long you will have to save if you know how much you can put aside each period?
• Do you have a little savings and wonder what it will be worth in the future?
• Are you comparing paying off your credit card debt and replacing it with a different type of loan?
• Is there something about your student loans that you would like to analyze?
• Do you get a periodic income from something or someone and want to calculate the present value of it?
