How to Calculate Hurdle Rate in Excel: A Complete Guide
The Hurdle Rate is the minimum rate of return on a project or investment required by a manager or investor. In corporate finance, it is often referred to as the "required rate of return" or the "target rate." If a project's expected internal rate of return (IRR) is lower than the hurdle rate, the project is typically rejected.
While the calculator above provides an instant analysis, financial analysts often build this model in Excel. This guide explains the logic behind the calculation and provides the specific Excel formulas you need.
The Hurdle Rate Formula
The most common method for calculating a hurdle rate is derived from the Weighted Average Cost of Capital (WACC), adjusted for the specific risk of the project. The formula is:
Hurdle Rate = WACC + Risk Premium
Where WACC is calculated as:
WACC = (E/V × Re) + (D/V × Rd × (1 – T))
- E: Market Value of Equity
- D: Market Value of Debt
- V: Total Value of Capital (E + D)
- Re: Cost of Equity
- Rd: Cost of Debt
- T: Corporate Tax Rate
How to Calculate Hurdle Rate in Excel
To set this up in a spreadsheet, you will need to organize your inputs and use basic arithmetic formulas. Follow this step-by-step setup:
Step 1: Set up your Input Cells
Assign the following cells (example coordinates):
- B1: Total Equity Value (e.g., 5000000)
- B2: Total Debt Value (e.g., 2000000)
- B3: Cost of Equity (e.g., 10%)
- B4: Cost of Debt (e.g., 5%)
- B5: Tax Rate (e.g., 21%)
- B6: Specific Risk Premium (e.g., 2%)
Step 2: Calculate Weights
First, determine the total capital and the weight of each component.
- Total Capital (Cell B7):
=B1+B2
- Weight of Equity:
=B1/B7
- Weight of Debt:
=B2/B7
Step 3: The WACC Formula in Excel
You can calculate the base WACC in a single cell using the following formula:
=((B1/(B1+B2))*B3) + ((B2/(B1+B2))*B4*(1-B5))
Step 4: Final Hurdle Rate
Finally, add your project-specific risk premium to the WACC to get the hurdle rate:
=WACC_Cell + B6
Real-World Example
Imagine a manufacturing company is considering a new factory. The company has $5 million in equity and $2 million in debt. Investors demand a 10% return on equity, and the bank charges 5% interest on debt. The corporate tax rate is 21%.
Because this new factory is in a volatile foreign market, the CFO adds a 2% risk premium to the standard cost of capital.
Using the calculator above or the Excel formulas provided:
- Total Capital: $7,000,000
- Weight of Equity: 71.43%
- Weight of Debt: 28.57%
- After-Tax Cost of Debt: 5% * (1 – 0.21) = 3.95%
- WACC: (71.43% * 10%) + (28.57% * 3.95%) = 8.27%
- Final Hurdle Rate: 8.27% + 2% = 10.27%
In this scenario, the new factory must generate a return on investment (ROI) greater than 10.27% to be considered viable.
Why is the Risk Premium Important?
The WACC provides a baseline "cost of money" for the company as a whole. However, not all projects carry the same risk. A project expanding an existing successful product line is safer than launching a brand new product in an unproven market.
By adding a Risk Premium input (as seen in our calculator and Excel guide), finance managers adjust the hurdle rate upward for riskier projects. This ensures that the potential high returns justify the increased risk of capital loss.
