Modified Internal Rate of Return (MIRR): A Refined Measure of Profitability
The modified internal rate of return (MIRR) is a variation of the IRR that considers the timing of cash flows. It is the discount rate that makes the future value of all cash inflows equal to the future value of all cash outflows.
MIRR is the discount rate that makes the future value of all cash inflows equal to the future value of all cash outflows, providing a more comprehensive measure of the project’s profitability.
This Modified Internal Rate of Return (MIRR) doesn’t explicitly account for the timing of cash flows. This is where the Modified Internal Rate of Return (MIRR) steps in, providing a more nuanced assessment of profitability. The MIRR is one of the capital budgeting techniques and it’s different because it looks at how cash comes in and goes out over time. It’s like a smarter way to see if an investment will make money.
Formula:
MIRR = (Future Value of Cash Inflows / Future Value of Cash Outflows)^(1/Time Period) – 1
What It Tells:
- Higher MIRR: A higher MIRR hints that the investment might be more profitable. It’s like saying, “Hey, this investment might make more money, considering when cash comes and goes.”
- Lower MIRR: A lower MIRR might mean the investment won’t be that profitable, factoring in the timing of cash flows.
Applications:
The MIRR looks at investments from a different angle, considering when cash flows happen, giving a clearer picture of their profitability!
MIRR is a useful capital budgeting method for projects or investments with uneven cash flow patterns. It is also useful for evaluating the sensitivity of a project to changes in the discount rate.
This is a handy tool when dealing with investments that don’t have even cash flow patterns. It’s like wearing a pair of glasses to see through the irregular cash flows!

Crunching Some Numbers:
By analyzing various scenarios, MIRR helps in assessing investments considering the timing and size of cash flows, providing a clearer perspective on their profitability!
Calculation Example 1:
Considering an investment’s future value of positive cash flows at $300,000 and the present value of negative cash flows at $200,000 over five years:
MIRR=(300,000/200,000)^1/5−1
Scenario 2: An investment of $50,000 yields $10,000 annually for seven years, with a final cash flow of $30,000. Calculate the MIRR.
- Cash Flows: -$50,000, $10,000, $10,000, $10,000, $10,000, $10,000, $10,000, $30,000
- MIRR: Approximately 6.51%
Here, the MIRR is around 6.51%, suggesting the investment’s potential return.
Scenario 3: An initial investment of $120,000 generates $25,000 annually for five years and a final cash flow of $50,000. Calculate the MIRR.
- Cash Flows: -$120,000, $25,000, $25,000, $25,000, $25,000, $25,000, $50,000
- MIRR: Approximately 10.64%
This investment seems to offer an MIRR around 10.64%, implying a potentially higher return.
Scenario 4: An investment of $200,000 results in $60,000 returns in the first year, $50,000 in the second year, and $30,000 in the third year. Calculate the MIRR.
- Cash Flows: -$200,000, $60,000, $50,000, $30,000
- MIRR: Approximately 9.82%
This investment’s MIRR is about 9.82%, indicating its potential return rate.
Scenario 5: An initial investment of $80,000 leads to $15,000 cash flows annually for eight years. Calculate the MIRR.
- Cash Flows: -$80,000, $15,000, $15,000, $15,000, $15,000, $15,000, $15,000, $15,000, $15,000
- MIRR: Approximately 7.97%
In this case, the MIRR calculates around 7.97%, indicating the potential return of the investment.
Scenario 6: An investment of $150,000 provides returns of $40,000 in the first year, $30,000 in the second year, and $20,000 in the third year. Calculate the MIRR.
- Cash Flows: -$150,000, $40,000, $30,000, $20,000
- MIRR: Approximately 14.05%
The MIRR for this investment is around 14.05%, suggesting a potentially higher return rate.
Scenario 7: An initial investment of $100,000 yields $20,000 in the first two years and $30,000 in the third year. Calculate the MIRR.
- Cash Flows: -$100,000, $20,000, $20,000, $30,000
- MIRR: Approximately 10.82%
The MIRR for this scenario is around 10.82%, indicating a potential return rate.
Capital Budgeting Techniques: Making Smarter Investment Choices
Advantages and Limitations of MIRR
MIRR offers several advantages:
- Considers Timing of Cash Flows: MIRR explicitly accounts for the timing of cash flows, providing a more refined measure of profitability compared to traditional IRR.
- Applicable for Uneven Cash Flows: MIRR is particularly useful for projects or investments with uneven cash flow patterns, where timing is crucial.
- Sensitivity Analysis: MIRR can be used to assess the project’s sensitivity to changes in the discount rate.
However, MIRR also has limitations:
- Computational Complexity: Calculating MIRR requires iterative methods or financial calculators, making it more complex than IRR.
- Multiple MIRRs: Certain projects may have multiple MIRRs, making it difficult to interpret the results.
- Ignores Other Factors: MIRR solely focuses on profitability and does not consider other factors such as strategic fit, market competition, and technological advancements.
Conclusion
The Modified Internal Rate of Return (MIRR) serves as a valuable tool for businesses to evaluate the profitability of long-term investments, considering the timing of cash flows. By providing a more refined measure of profitability compared to traditional IRR, MIRR empowers businesses to make informed investment decisions that align with their financial goals. However, it is crucial to acknowledge the limitations of MIRR and utilize it in conjunction with other decision-making tools for a comprehensive evaluation.
