What will $1,130 amount to in 5 years at 5% interest?

We have to find the future value of a single sum

Using the compound interest formula

FV = PV (1+rate)^n where

PV = present value = $1,130

Rate = 5%

N = time period = 5 years

FV = amount in 5 years = 1,130 (1+5%)^5 = $1,442.20

What is the present value of $10,000 due in 11 years time at 5% compound interest?

Here we are given the future value and we have to find the present value

PV = FV/(1+rate)^n where

FV = future value = 10,000

Rate = 5%

N = time period = 11 years

PV = 10,000/(1+5%)^11 = $5,846.79

#### Solution Summary

The solution explains some questions relating to time value of money

Calculations of the Time Value of Money

1) You invest $20,000 today, at a rate of 10% compound quarterly. What will the investment be worth at the end of year twenty?

2) You are offered an annuity that will pay you $9,000 at the end of each of the next 10 years. What is the maximum amount you would be willing to pay today for this annuity? (Assume you require a 15% rate of return on an investment of this nature.)

3) You have $15,000 to put down on a new house that cost $200,000, and you have been quoted the following finance terms by your local banker: 6% Annual Percentage Rate, for 30 years. If you decide to purchase this home, what will your monthly payment be? Additionally, over the life of the loan what would your total interest expense be?

4) You want to start saving for your child's education. You project that your child will need $170,000 to attend school 15 years from now. If you can earn a rate of return of 10% compounded semi-annually on a given investment, what dollar amount will you need to invest today to ensure your child can attend college?

5) Steaks Galore has $190,000 in excess cash that it wishes to invest. Bank One offers a certificate of deposit that is paying 10%, compounded monthly.

In addition, you must show all of your work.) Additionally, what is the nominal and period rate of interest offered by Bank One?

6) You plan on depositing $3,000 in an account at the end of each of the next 5 years. If the account is paying interest at an annual rate of 10% per year, what will the total value of your investment be at the end of the 10th year?

If upon receipt of these cash inflows, you can re-invest the amounts received at a rate of 10%, what will the total future value of this investment be?

9) While Bob Jones was a student at Tiffin University, he borrowed $43,063 in student loans at an annual rate of 7 percent. If Bob repays $500 per month, how long, to the nearest year, will it take him to repay the loan?
