We now focus on the effect that inflation may have on the worker planning to save for retirement. If the interest rate on savings is rs and the inflation rate is r^, the monthly amount put into savings by the worker must be discounted by an effective rate rs + r^. Then once the worker is retired the monthly annuity must be discounted by the rate rs — r^. Returning to the earlier example consider the case in which rs = 0.10, the worker will save for 40 years and live on a monthly annuity whose inflation adjusted value will be $1500 for 30 years, and the rate of inflation will be ri = 0.03 for the entire lifespan of the worker/retiree. Assuming the worker will make the first deposit in one month the present value of all deposits to be made is
