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?
