Adjusting future values for inflation
You can now put together what you learned in the previous exercises by following a simple methodology:
- First, forecast the future value of an investment given a rate of return
- Second, discount the future value of the investment by a projected inflation rate
The methodology above will use both the .fv() and .pv() functions to arrive at the projected value of a given investment in today's dollars, adjusted for inflation.

Instructions
- Calculate the future value of a $10,000 investment returning 8% per year for 10 years using
.fv()and assign it toinvestment_1. - Calculate the inflation-adjusted present value of
investment_1, using an inflation rate of 3% per year and assign it toinvestment_1_discounted.
