Build Up Rate Calculator
The Build Up Rate Calculator is a vital tool for estimating the cost of equity for a private company. In the absence of market-based beta or stock data, financial analysts and business appraisers often rely on the build-up method to derive the required rate of return. This method is especially beneficial when valuing closely held businesses or startups that do not trade publicly.
The cost of equity is crucial because it influences investment decisions, business valuations, and the overall capital structure of a company. By accounting for different types of risk premiums, the Build Up Rate Calculator helps quantify the return investors would require for investing in a specific business.
Formula
The formula for calculating the build-up rate is:
Build Up Rate = Risk-Free Rate + Equity Risk Premium + Size Premium + Specific Company Risk Premium
Each component represents a type of risk or market expectation that adds to the return investors demand:
- Risk-Free Rate: Generally the return of long-term government bonds (e.g., 10-year Treasury bond).
- Equity Risk Premium: The additional return expected from investing in the broader equity market over the risk-free rate.
- Size Premium: Small businesses typically carry more risk than large-cap firms, hence a size-related premium is added.
- Company-Specific Risk Premium: Reflects risks unique to the company—such as industry, management, or geographic exposure.
How to Use the Build Up Rate Calculator
Using this calculator is simple and requires four input values:
- Risk-Free Rate (%): Enter the current yield of a secure long-term government bond.
- Equity Risk Premium (%): Use average market premiums or sources like Duff & Phelps.
- Size Premium (%): Estimate based on the business’s size relative to others in its industry.
- Specific Company Risk Premium (%): Consider factors unique to the company, such as competition, volatility, management, etc.
Click the “Calculate” button to get the Build Up Rate (%).
Example
Let’s assume you are valuing a small retail company. Based on your research:
- Risk-Free Rate: 4%
- Equity Risk Premium: 6%
- Size Premium: 2.5%
- Specific Company Risk Premium: 3.5%
Using the formula:
Build Up Rate = 4 + 6 + 2.5 + 3.5 = 16%
This means investors would expect a 16% return on investment due to the company’s risk profile.
FAQs about Build Up Rate Calculator
1. What is a Build Up Rate?
The Build Up Rate is the estimated required rate of return for investing in a business, especially one that is privately held.
2. Why use the build-up method instead of CAPM?
Because the build-up method doesn’t require a beta, it’s ideal for valuing private companies without public trading data.
3. How do I determine the risk-free rate?
Use the current yield of a government-issued bond, typically the 10-year Treasury bond.
4. Where can I find the equity risk premium?
You can use historical market data or industry-standard sources like Duff & Phelps or Ibbotson Associates.
5. What is the size premium?
An additional return component to reflect the extra risk of investing in smaller, less liquid companies.
6. What factors influence the company-specific risk premium?
Industry risk, management quality, customer concentration, market competition, and financial health.
7. Can I use this calculator for startups?
Yes. In fact, it’s well-suited for startups that lack public financial data.
8. Is this calculator suitable for valuing real estate?
Not directly—this tool is better for valuing operating businesses, not passive investments like real estate.
9. Should I update inputs regularly?
Yes, especially the risk-free rate and market premium, which may change over time.
10. Can the build-up rate be negative?
Unlikely, since all components are additive and represent positive risk-related returns.
11. Is this method acceptable in professional valuations?
Yes. The build-up method is commonly used by certified business appraisers and analysts.
12. How is the build-up rate applied in DCF models?
It serves as the discount rate to convert future cash flows into present value.
13. Can I include country risk premium in the build-up rate?
Yes. For international valuations, adding a country risk premium is advisable.
14. Is the size premium fixed?
No. It varies based on the company’s revenue, market cap, or other financial indicators.
15. Does industry affect the company-specific premium?
Absolutely. Risk levels vary significantly across industries, from biotech to construction.
16. Is there a range for build-up rates?
Typically, they range from 10% to 30% depending on risk factors.
17. What are common mistakes in using this method?
Double-counting risks, outdated data, and overly subjective company-specific premiums.
18. Can I use this for loan evaluations?
Not directly—it’s meant for equity valuation, not debt cost analysis.
19. Do VCs use this method?
Not often. VCs usually use IRR-based models, but the build-up rate can inform ROI expectations.
20. How is this different from WACC?
The Build Up Rate calculates cost of equity only, while WACC includes both debt and equity costs.
Conclusion
The Build Up Rate Calculator offers a practical and reliable way to assess the required rate of return on equity for businesses that lack market comparables. By focusing on risk-adjusted components like market, size, and company-specific risks, this method ensures a thorough and customized valuation. Whether you’re a financial analyst, business owner, or investor, incorporating this tool can lead to more informed decisions and accurate business appraisals.
