Math Problem Statement
You are considering making a movie. The movie is expected to cost $10.1 million up front and take a year to produce. After that, it is expected to make $4.5 million in the year it is released and $1.9 million for the following four years. What is the payback period of this investment? If you require a payback period of two years, will you make the movie? Does the movie have positive NPV if the cost of capital is 10.2 %?
Solution
Let's address each part of this question systematically.
Step 1: Calculate the Payback Period
The payback period is the time it takes to recover the initial investment of $10.1 million through the cash inflows generated by the movie.
Cash Flows:
- Initial Investment (Year 0): $10.1 million (outflow)
- Year 1: $4.5 million
- Year 2: $1.9 million
- Year 3: $1.9 million
- Year 4: $1.9 million
- Year 5: $1.9 million
Cumulative Cash Flows
Let's calculate cumulative cash flows year-by-year to determine when the initial investment is fully recovered.
-
Year 1: $4.5 million
Cumulative: $4.5 million -
Year 2: $4.5 million + $1.9 million = $6.4 million
Cumulative: $6.4 million -
Year 3: $6.4 million + $1.9 million = $8.3 million
Cumulative: $8.3 million -
Year 4: $8.3 million + $1.9 million = $10.2 million
Cumulative: $10.2 million
By the end of Year 4, the cumulative cash inflow ($10.2 million) slightly exceeds the initial investment of $10.1 million. Therefore, the payback period is just under 4 years.
Decision on the Payback Requirement
Since the required payback period is 2 years, and our payback period is around 4 years, we would not make the movie based on this criterion.
Step 2: Calculate the NPV (Net Present Value)
The NPV is calculated by discounting each cash flow back to present value using the cost of capital (10.2%) and then summing these present values.
The formula for NPV is: where .
NPV Calculation
- Initial Investment (Year 0): million (already a present value)
- Year 1:
- Year 2:
- Year 3:
- Year 4:
- Year 5:
Now, sum these values:
Conclusion
- Payback Period: Approximately 4 years. Since this exceeds the required 2 years, we would not make the movie based on payback period criteria.
- NPV: million, or , which is negative. A negative NPV means the project does not add value, so we would not proceed with the movie based on NPV either.
Summary: The movie does not meet the required payback period and has a negative NPV. Therefore, it would be rejected on both financial criteria.
Would you like further details on any part of this solution? Here are some related questions to consider:
- What factors could improve the payback period or NPV in this scenario?
- How does the choice of discount rate affect the NPV calculation?
- What are alternative metrics to evaluate project viability?
- What are the limitations of using the payback period as a decision criterion?
- How would an increase in expected cash flows affect both the payback period and NPV?
Tip: NPV is often preferred over the payback period because it accounts for the time value of money, while the payback period simply measures time without discounting.
