If you currently have $20,000 in the bank, and plan to deposit an additional $100 at the beginning (1) of each month (12 periods per year) for 40 years at an annual interest rate of 10.00%, how much will you have at the end of the 40 years? $1,711,691.29 vestment will be worth at the end eposits at a constant interest rate. n to deposit an additional $100 at ear) for 40 years at an annual t the end of the 40 years?

In this example, we want to find the payment on a $50,000 30- year loan. Payments will be made monthly (12 per year) and the annual interest rate is 12.00%. Payments are at the end of the month (0) and the balance (amount still owed) at the end of the 30 years will be $0.

In this example, we want to determine how much we will have to save monthly (12 per year) if we start with $5,000 and the money is invested at an annual rate of 8.00% for 20 years.

This is the function that a lottery winner must use to decide whether to take a series of future payments or a lump sum (present value). In this example, we have won a $2,000,000 lottery which will be paid off at $100,000 per year for 20 years. If we could earn 6.00% on a lump sum and withdraw $100,000 per year, how much money would we have to start out with to exactly duplicate the lottery's performance (i.e., get $100,000 per year for 20 years and have exactly $0 left at the end)? This shows us that we would need $1,215,811.65 invested at 6.00% to make this happen. If the lottery offers us more than $1,215,811.65, we should take it, invest the money at 6.00%, withdraw $100,000 each year, and we will STILL have money left over at the end. $1,215,811.65 ies of future e function that a e a series of future y which will be ould earn 6.00% how much money ate the lottery's ars and have would need pen.

In this example, we have a goal of $1,000,000 in 20 years. We will receive a return of 6.00% per year. We will save $300 at the beginning (1) of each month (12 per year) for 20 years. How much would we have to begin with to reach our goal? ($260,012.54) would have 20 years.

In this example, we know we can afford payments of $500. The interest rate on the loan will be 6.00% per year, and we will make monthly payments at the END of each month. The loan will be paid back over a period of 5 years, and the balance owed at that time will be $0.

This returns the rate per period! You must multiply the rate per period by the number of periods per year to get the annual interest rate! In this example, we are starting with a balance of $20,000 in our savings account. We can afford to deposit $200 at the end (0) of each month. Our goal is to have $500,000 in the account at the end of 25 years.

The result will be the RATE PER PERIOD, not the annual rate, so to get the annual rate, you must multiply by the periods per year! In this example, we want to find the rate on a $50,000 30-year loan. Payments will be made monthly (12 per year) and the monthly payments are $300.
