Example 1) What is the accumulated value of a series of payment of USD1,000 each month, accumulating at an interest rate of 10% per year, for 10 years.
Example 2) How much monthly payments should be paid to yield an accumulated value of USD50,000 at the end of 5 years assuming interest rate 7% per year.
Example 3) Stocks bought 10 years ago at the price of USD10,000 became an accumulated value of USD30,000. What is the yearly compound interest rate?
Example 4) How long period needed to yield accumulated value of USD10,000 with monthly deposits of USD50,000 assuming annual 5% interest rate.
Example 5) If a man bought a house at USD300,000 and sold at USD500,000 10 years later. What is the annual rate of return?
Example 6) Assuming annual inflation rate 3%, what is the present value of USD1,000,000 at the end of 10 years.
Example 7) If you want to borrow money with minimum interest, what is the best way?
Example 8) If you want to redeem your loan with equal monthly payments in 10 years. What is the method with monthly payments amount?
Example 9) There is a new car you want to buy. You can not afford to buy the new car so you want to wait until you can buy a secondhand car. How much will it be?
Example 10) You put USD20,000 into your stock account 3 years ago and withdrew USD5,000 6 months ago. If your stock valuation is USD30,000 what is the accumulated earning rate and yearly earning rate?
