Suppose that Yvette is 45 years old and has no retirement savings. She wants to begin saving for retirement, with the first payment coming one year from now. She can save $12,000 per year and will invest that amount in the stock market, where it is expected to yield an average annual return of 15.00% return. Assume that this rate will be constant for the rest of her's life. Yvette would like to calculate how much money she will have at age 65. Using a financial calculator yields a future value of this ordinary annuity to be approximately at age 65. Yvette would now like to calculate how much money she will have at age 70 . Using a financial calculator yields a future value of this ordinary annuity to be approximately at age 70. Yvette expects to live for another 25 years if she retires at age 65 , with the same expected percent return on investments in the stock market. Using a financial calculator, you can calculate that Yvette can withdraw at the end of each year after retirement (assuming retirement at age 65), assuming a fixed withdrawal each year and $0 remaining at the end of her life. Yvette expects to live for another 20 years if she retires at age 70 , with the same expected percent return on investments in the stock market. Using a financial calculator, you can calculate that Yvette can withdraw at the end of each year after retirement at age 70
