Private Equity IRR (Internal Rate of Return) Calculator
IRR (Internal Rate of Return) is the standard return metric for PE and VC investments. This calculator computes IRR, MOIC, and XIRR instantly; no spreadsheet required.
It is built for PE professionals, VC investors, founders, and LPs who need PE-specific outputs: IRR and MOIC side by side, exact-date XIRR for LP-level modeling, and a gross vs net IRR toggle to show the impact of fees and carry on actual returns.
What is IRR in Private Equity?
IRR is the annualized return implied by the timing and size of investment cash flows. It is the internal rate of return at which the net present value of all cash flows equals zero.
Why it matters in PE and VC: timing changes how returns should be judged. A $1 million distribution in Year 2 is worth far more than the same $1 million received in Year 7, and IRR captures that difference from the initial investment through exit.
How it differs from ROI: ROI tells you how much money was made relative to capital invested. IRR tells you how quickly that value was created.
That makes IRR especially useful for comparing deals with different sizes, holding periods, and cash flow timing. It is also the standard performance metric in LP reporting because it reflects the time value of money and shows whether returns are clearing the cost of capital.
PE and VC professionals use IRR to screen deals, compare exits, and assess manager performance across funds and vintages. It is not perfect, but it remains the default return language across private markets.
For broader context on where return analysis fits into sourcing, diligence, execution, and exit, see the PE/VC investment process.
How to Calculate IRR: Formula and Method for Calculator cash flow
IRR is the rate that makes the present value of all cash flows equal zero. In a return calculator, this calculation is used to test the relationship between the initial outflow and all future cash flows.
0 = CF0 + CF1 / (1 + r)^1 + CF2 / (1 + r)^2 + ... + CFn / (1 + r)^n
Here, r is the IRR. Because the equation usually cannot be solved directly, calculators use iteration to test a rate, measure the error, and refine the estimate until the result converges.
That is the logic behind the Newton-Raphson method. In practical terms, the calculator starts with a guess, checks whether the NPV is above or below zero, and keeps adjusting until it lands on the correct rate. Excel’s IRR and XIRR functions use the same general approach, and this calculator does as well.
Take a simple 3-year example. An investor puts in $1.0 million at Year 0, then receives an inflow of $200,000 in Year 1, $300,000 in Year 2, and exits for $1.1 million in Year 3.
Total proceeds are $1.6 million, so MOIC is 1.6x. Based on timing, the IRR is about 21.7%.
That distinction matters because the calculator is measuring both value and timing, not just total cash returned. If you are building returns from entry price and exit assumptions, it also helps to understand how equity value is calculated in PE.
For annual cash flows, standard IRR is usually enough. For real PE and VC cash flows that occur on exact dates, XIRR is more accurate.
What is a Good IRR? PE and VC Benchmarks
A good IRR depends on strategy, risk, and holding period, but benchmarks still help. In broad terms, 12% to 18% net IRR is often acceptable for large-cap buyout, 15% to 25% is common for mid-market PE, and early-stage VC usually targets higher returns.
|
Strategy |
Typical Net IRR Range |
Typical Holding Period |
|
PE Buyout (Large Cap) |
12–18% |
4–6 years |
|
PE Buyout (Mid-Market) |
15–25% |
3–5 years |
|
Growth Equity |
20–30% |
3–5 years |

Early-Stage VC |

7–10 years |
|
Late-Stage VC |
15–25% |
4–6 years |
|
Real Estate PE |
12–20% |
5–7 years |
These are typical target ranges, not guarantees. Actual performance varies by vintage year, market conditions, sector mix, leverage, and exit timing.
What does a 12% IRR mean? It can be acceptable in large-cap buyout, but it is usually below target for venture.
What does a 22% IRR mean? It is strong for mid-market PE and solid for many growth deals, while early-stage VC often targets even higher returns.
What does a 20% IRR over 5 years mean? It translates to roughly 2.5x MOIC, which is a strong result in many PE contexts.
This is also why net IRR matters more than headline gross IRR. LPs ultimately care about what survives after fees and carry.
Benchmark ranges make more sense when you compare what is a good IRR for PE with what is a good IRR for VC in the right strategy context.
Gross IRR vs Net IRR: What's the Difference?
Gross IRR measures return before fees and carry. Net IRR measures what the LP actually receives after management fees, carried interest, and fund expenses.
That distinction matters because a strong gross return can look much less attractive once fund economics are applied. In many cases, the spread between gross and net IRR is around 3 to 8 percentage points, which can materially change how investors evaluate fund performance and compare investment returns.
Gross IRR is useful for asset-level performance. It shows how the investment performed before fee drag and helps assess return on investment at the deal or fund level.
Net IRR is what LPs care about. It reflects actual investor outcomes and is the more relevant comparison metric when investors evaluate funds and compare investment opportunities across managers.
The calculator above includes a Gross/Net toggle for that reason. When switched to Net, it applies management fee and carry assumptions to estimate LP-level return and give a more realistic view of investment returns.
This is also where the hurdle matters. Many PE funds require the fund to clear an 8% preferred return before carry applies, which changes cash splitting and affects net IRR.
That impact becomes easier to follow when you compare gross IRR vs net IRR and hurdle rate in private equity within the same context.
IRR vs MOIC: Which Metric Matters More?
PE professionals use IRR and MOIC together because each fills a gap the other leaves open. IRR measures speed of return. MOIC measures total cash returned relative to capital invested.
A high IRR can come from a short-duration deal that creates limited absolute wealth. A high MOIC can look impressive while hiding how long it took to achieve.
Side-by-side example:
Deal A returns 3.0x MOIC over 7 years. That implies roughly 17% IRR.
Deal B returns 2.0x MOIC over 3 years. That implies roughly 26% IRR.
Which is better depends on the objective. If faster capital recycling matters more, Deal B may be stronger. If total value creation matters more, Deal A may be preferable.
That is why LPs and GPs do not rely on IRR alone. They want to see both how much money came back and how long it took.
The calculator outputs IRR and MOIC side by side for exactly that reason.
Common Mistakes When Using IRR
- Ignoring the reinvestment assumption. Standard IRR assumes interim cash flows can be reinvested at the same IRR, which is rarely realistic.
- Missing the multiple-IRR problem. If cash flows switch from negative to positive and back again more than once, more than one mathematically valid IRR may exist. A good calculator should flag that issue instead of returning a misleading number.
- Ignoring scale. A 40% IRR on a $100K investment may create far less value than a 15% IRR on a $50M investment. That is why IRR should always be reviewed alongside MOIC and absolute dollars returned.
IRR Calculation Examples: PE Buyout, VC, and Fund Level
PE buyout example: a mid-market PE fund invests $25M of equity. It receives $2M per year in dividend recaps for Years 1 through 4, then exits in Year 5 for $60M and receives the final $2M distribution.
Cash flows: Year 0: -$25M, Years 1–4: +$2M each, Year 5: +$62M.
Output: approximately 24% IRR and approximately 2.7x MOIC. Verify this using the calculator above.
VC example: a VC fund invests $5M at Series A and receives no interim distributions. The stake is sold for $35M after 7 years.
Cash flows: Year 0: -$5M, Year 7: +$35M.
Output: approximately 32% IRR and 7.0x MOIC. Verify this using the calculator above.
LP fund-level example: an LP contributes $1.0M in January 2020, $500K in July 2020, and $500K in March 2021. It receives $800K in June 2023 and $2.5M in December 2024.
Because the dates are irregular, this should be modeled using XIRR.
Output: approximately 18% XIRR, approximately 1.6x MOIC, and an investment duration of about 4 years and 11 months. Verify this using the calculator above.
