I want to receive updates regarding this question via email.

NPV of a Perpetuity --> How to improve?

Hi PrepLounge community,

I stumbled upon a difficult question in a recent case - looking forward to hearing your inputs on this!

Scenario (numbers are simplified)

- A tourism investment yields a positive cash flow of 15M every year, with no growth (perpetuity rent)
- We have an up-front investment of 100M
- Cost of capital = 10%
- NPV = -100 + 15/0.1 = 50M

Question and answer

Question
Your client is not satisfied by the NPV: 50M is too low. From a financial perspective, what could she do to improve the NPV to 100M?
And are these options difficult, medium or easy to implement?

Answer
We could:
i) Try to lower the cost of capital to 7.5% from 10%
--> By finding cheaper ways of financing such as public funding. 
Level: medium, possible only if public funding is available or if we have debt in our financing mix.
ii) Try to have a constant growth rate of Cash Flow of ~2.5%
--> By increasing each year Q (thru occupancy) or P (thru added services)
Level: easy, it's doable to have a +2.5% in the first years of a new business
iii) Try to increase Cash Flow to +20M a year from +15M
--> By finding extra sources of revenues, even if gross margin is relatively reduced
Level: difficult, +33% a year is a huge increase if we keep the same biz model
iv) Try to reduce Capex to -50M from -100M
--> By drastically reducing infrastructure costs
Level: difficult, we can't expect the same level of revenues if we slash the quality/quantity of our infrastructure
v) A mix of these approaches

I feel like this is a very standard approach, I have no experience in finance. What would you add/comment to this answer?

Thank you in advance for your support!

Dee

Hello Dee,

Your answer sounds good, you have basically cover all the possibilities. Just remember that there are several ways to increase your yearly cash flow, not only findind new sources of revenues.
More over, a good opportunity could be to try to spread the initial investment over several years (without paying "interests"or at least paying less than 10% per year)

Does it make sense?
Best,
Luca

You may also move a part of investment cost to other years, so that they are discounted and have lower effect on NPV.

Hi Dee,

your approach is good, as a way to increase Cash Flow I would also consider a reduction of the yearly costs of the business, besides finding extra source of revenues.

Best,
Francesco

Agree with the approach, and I would try to find on top ways to increase the cash flow -even if the case does not specifically ask for this-. 

Cheers,

Clara

Valuation Cases
Understanding how to determine a company's value is a crucial skill in strategy consultingstructured approach to valuation is essential. While full-scale valuation analyses are rare in case interviews, you may still be asked questions like, "How much would you pay for company XY?" or "Is this offered price reasonable?" Let's take a closer look on how to approach valuation in a case interview: The Most Common Methods of Valuing Are the Discounted Cash Flow (DCF) and the Industry Multiple MethodSince case interviews are designed to test structured thinking rather than financial modeling skills, you won’t be expected to conduct a full valuation. Instead, you’ll likely need to estimate the worth of a company, product, patent, or service, often with limited data. Your task is to provide a logical and well-reasoned valuation rather than an exact figure.Discounted Cash Flow MethodThe first valuation method is the Discounted Cash Flow Method. This method shows how much money you would have in your savings account at a certain interest rate in order to provide you with the same annual cash flow generated by the company that is being evaluated.To calculate this, you divide projected annual cash flows by an appropriate discount rate (or interest rate). Naturally, the discount rate for a business investment is higher than that of a savings account because investing in a company carries more risk.👉 For more details on how to use the Discounted Cash Flow (DCF) method, have a look at our Net Present Value (NPV) lessonIndustry Multiple MethodThe Industry Multiple Method provides a relative valuation by comparing a company to similar businesses in the industry. This is especially useful when additional factors—such as brand value or strategic positioning—affect valuation beyond simple cash flow calculations.For example, football teams are often overvalued compared to their financial returns because their brand, fan base, and sponsorship potential add intangible value. The industry multiple method accounts for such variations.The process involves:Identifying a relevant financial metric (e.g., revenue, EBITDA, or book value).Finding the average multiple for similar companies (e.g., P/E ratio, EBITDA multiple).Multiplying the chosen metric by the industry multiple to estimate value.Example: Price-to-Book Ratio (P/B)If a company’s assets are valued at $200 million but it was sold for $100 million, the price-to-book ratio is 0.5 (100M ÷ 200M). By averaging this ratio across comparable companies, you can estimate a reasonable valuation for a target firm.Other commonly used valuation multiples include:Price-to-Earnings Ratio (P/E)EV/EBITDA MultipleSince precise calculations aren’t required in case interviews, you don’t need to memorize industry-specific multiples. However, a rough understanding can help:A typical industry multiple can be EBITDA × 10.Discount rates vary from 3% (inflation level) to 20% (high-risk investments). Key TakeawaysUse the Discounted Cash Flow (DCF) method to value a firm based solely on its expected profits.Use the industry multiple method to double-check if the DCF valuation is reasonable. Sometimes other aspects need to be factored in like brand value, customer loyalty, liabilities, etc.There are several types of industry multiples to choose from. For more precise valuation, choose more types of industry multiples.Practice M&A cases to optimize your valuation-techniques:
