Gross IRR (Internal Rate of Return) is the annualized percentage return on an investment calculated before subtracting any fees, expenses, or carried interest. It reflects the raw performance of the underlying investment—how much money the company or deal actually generated—independent of what intermediaries take off the top. For angel investors evaluating opportunities, gross IRR provides a clear picture of the investment's true earning power.
How It Works
When you invest in a startup or through an investment fund, two layers of returns exist. The gross IRR measures the first layer: the actual gains from the business or portfolio. This is calculated by determining what annual rate would turn your initial investment into the final exit proceeds, ignoring all costs along the way.
The calculation remains straightforward: it answers the question, "What annual percentage return did this deal generate from day one to exit?" If you invested $100,000 and received $300,000 back over five years, the gross IRR reflects that growth rate without reducing it by management fees or profit-sharing arrangements.
Why It Matters for Investors
Gross IRR serves as your baseline for investment quality. It lets you compare the actual performance of different deals on equal footing, since every investment will have different fee structures. Understanding gross returns helps you evaluate whether a manager or deal is worth the fees they charge.
When comparing fund managers, always request both gross and net IRR figures. A manager claiming 30% returns might deliver only 20% net after fees—a significant gap that directly impacts your wealth. Gross IRR also helps you benchmark against market standards and peer performance.
Example
Imagine you join a syndicate investing in an early-stage SaaS company. Your $50,000 check is one of many. Five years later, the company exits at a $200 million valuation. Your share returns $175,000. The gross IRR on that investment is approximately 28% annually.
However, the syndicate lead took a 20% carry (profit share) and charged 2% annual management fees. After these deductions, your net IRR drops to around 18%. Both numbers are accurate—gross IRR shows what the deal earned, while net IRR shows what you actually keep.
Key Takeaways
- Gross IRR excludes all fees, expenses, and profit-sharing arrangements from the return calculation
- Always compare gross IRR across investments to evaluate deal quality on a level playing field
- The gap between gross and net IRR reveals how much fees and carry cost you—often 5-15% annually
- Request gross IRR figures from fund managers to understand true investment performance before their cuts
