Solution: $13,583.56 (The answer is actually -$13,583.56, as this represents an outflow to savings.)
In this case, we do not need to make the inflation adjustment. This problem asks how much Frank needs
to save at the end of each year, so the savings will be level. Remember, when the payment is level, the

,inflation adjustment is not called for. Inflation should have already been taken into account to calculate
the need for an additional $380,000.
Dan and Barbara have saved $850,000. Assume that inflation is 3% and after-tax earnings are 9%. Also

The Smiths are a 50-year-old couple with an annual retirement budget of $75,000 (in today's dollars).
They want to plan for a retirement life expectancy of 25 years (starting at age 65), and assume a 3.5%

Solution: $125,651.16 (This becomes our starting income payment in Step #2.)
Step #2: Calculate the PVAD of 25 years of payments, using a first payment amount of $125,651, and
factoring both inflation (3.5%) and the rate of return (7%) (i.e., a serial payment).
