Good news: You will almost certainly be a millionaire by the time you retire in 50 years. Bad news: The inflation rate over your lifetime will average about 3.6%. a. What will be the real value of $1 million by the time you retire in terms of today’s dollars? (Do not round intermediate calculations. Round your answer to 2 decimal places.) b. What real annuity (in today’s dollars) will $1 million support if the real interest rate at retirement is 2.6% and the annuity must last for 20 years? (Do not round intermediate calculations. Round your answer to 2 decimal places.)
real value = nominal value / (1 + inflation rate)number of years
real value = $1,000,000 / (1 + 3.6%)50
real value = $170,613.04
PV of annuity = P * [1 - (1 + r)-n] / r,
where P = periodic payment. We need to calculate this.
r = interest rate per period. This is 2.6%.
n = number of periods. This is 20.
$170,613.04 = P * [1 - (1 + 2.6%)-20] / 2.6%
P = $170,613.04 * 2.6% / [1 - (1 + 2.6%)-20]
P = $11,047.99
Real annuity supported is $11,047.99
