MOIC vs IRR: The 60-Second Answer
MOIC (Multiple on Invested Capital) measures how many times an investor multiplied their money: invest $1M, get back $3M, that is a 3x MOIC. IRR (Internal Rate of Return) measures the same outcome as an annualized percentage, so it punishes slow returns: 3x in 5 years is a strong 24.6% IRR, while 3x in 10 years is a mediocre 11.6%. You can model both for your own round with the Round Funded investor ROI calculator.
Founders who understand this math negotiate better, size their asks better, and stop being surprised by investor behavior. Here is the whole topic in one read.
What Is MOIC?
MOIC = Total value returned / Total capital invested.
It is the simplest number in venture math, which is why investors quote it constantly:
- Invest $500K, company exits and returns $5M to that investor: 10x MOIC.
- Invest $2M, the stake is now worth $2M: 1x MOIC (break-even on paper).
- Invest $1M, company dies: 0x MOIC.
Two nuances founders should know:
- Realized vs unrealized. Until an exit, MOIC is a paper number based on the latest round's valuation. A fund saying "our portfolio is at 3x" usually means mostly unrealized marks.
- Gross vs net. A fund's gross MOIC ignores its fees and carry; the LPs (the fund's own investors) receive the net figure. The gap is typically meaningful, which is why funds need big gross outcomes to deliver acceptable net returns.
MOIC's blind spot is time. It treats 3x in 3 years and 3x in 13 years as the same result. They are not, and that is exactly what IRR exists to capture.
What Is IRR?
IRR is the annualized rate of return that accounts for when money goes in and comes out. Conceptually: what constant yearly interest rate would turn the invested cash flows into the returned cash flows on those exact dates.
The intuition beats the formula. For a single check returned in one exit:
IRR = MOIC^(1/years) - 1
So the same multiple produces wildly different IRRs depending on speed:
- 3x in 3 years: 44.2% IRR
- 3x in 5 years: 24.6% IRR
- 3x in 10 years: 11.6% IRR
At 11.6%, an LP would ask why the fund did not just buy an index fund. Time is not a detail in venture math, it IS the math.
MOIC vs IRR vs ROI: The Comparison
| Metric | What it answers | Formula (single exit) | Blind spot |
|---|---|---|---|
| MOIC | How many times did the money multiply? | Returned / Invested | Ignores time |
| IRR | What annual rate did this compound at? | MOIC^(1/years) - 1 | Manipulable by early partial exits; unstable on short horizons |
| ROI | What percent gain overall? | (Returned - Invested) / Invested | Same as MOIC, minus one; ignores time |
Worked example, same deal, three lenses: a fund puts $2M into your seed round and receives $10M when the company is acquired 6 years later.
- MOIC: 10 / 2 = 5x
- ROI: 400%
- IRR: 5^(1/6) - 1 = 30.8% per year
All three describe one outcome. Investors will usually quote the MOIC in conversation ("that was a 5x for us") and the IRR in LP reporting, because LPs compare funds against time-adjusted alternatives.
What Returns Do VCs Actually Target?
This is where founder empathy comes from. The standard mental model in 2026:
- A venture fund aims for roughly 3x net MOIC to its LPs over a ~10-year life, which requires more like 4-5x gross before fees. In IRR terms, good venture funds target 20-30%+ net IRR.
- The power law does the work. In a typical early-stage portfolio, most investments return 0-1x, a few do 3-5x, and one or two outliers must return the entire fund on their own.
- That is why your deal must look like a 10-50x. A seed fund writing a $2M check at a $20M post-money valuation is not hoping you 3x. They need a credible path to a 10x+ outcome, because your line item has to be able to carry the fund's misses.
The practical translations for founders:
- "Nice business, not venture scale" is a math statement, not an insult. A likely-3x company is a fine company and a bad seed fund investment.
- Round size and valuation set the required exit. Raise at $20M post and the fund's model wants a plausible $200M+ outcome. Raise at $8M post and $80M clears the same bar. Your valuation ask is a promise about the exit distribution.
- Speed matters to funds in their harvest years. A fund in year 7 of 10 needs outcomes sooner; the same MOIC helps them less if it lands after the fund's extensions run out.
Related fund metrics you will hear: TVPI (total value to paid-in, the fund-level MOIC including unrealized marks), DPI (distributions to paid-in, the cash actually returned), and RVPI (the still-unrealized remainder). DPI is the one LPs ultimately eat.
Model Your Own Round: Where Round Funded Fits
The fastest way to internalize this math is to run your own numbers. The free Round Funded investor ROI calculator lets you model a check into your round: entry valuation, exit scenarios, years to exit, and it returns the implied MOIC and IRR your investor would see.
Then use it in anger: Round Funded pairs the math with a database of 10,000+ active investors filtered by stage and sector, plus AI-drafted outreach from your own Gmail, so the investors whose return model your round actually fits are the ones you contact.

You can pressure-test the other side of the equation with the startup valuation calculator and the pre-money vs post-money calculator.
Using Investor Math in Your Raise: Step by Step
- Run your round through the Round Funded ROI calculator: your target valuation, a realistic exit range, and 5-8 year horizons. Look at the MOIC and IRR from the investor's seat.
- Check the 10x test. If a seed check at your valuation cannot plausibly return 10x, either the valuation is too high for venture or the investor type is wrong for you.
- Size the ask against the exit story. Anchor the raise and valuation to an exit multiple you can defend out loud, using the valuation calculator as a sanity check.
- Match investor type to your return profile. Venture-scale outcome: pitch VCs. Durable 3-5x profile: angels, family offices, and revenue-based options fit better.
- Put the numbers in the deck. A slide showing entry valuation, exit comps, and implied investor MOIC signals you understand their business. See funded examples in the pitch deck library.
- Target investors whose model you fit in the Round Funded database: 10,000+ active investors, filterable by stage, sector, and check size.
Frequently Asked Questions
What is the difference between MOIC and IRR?
MOIC is the raw multiple (money out divided by money in) and ignores time. IRR annualizes the same outcome, so speed changes it dramatically: 3x in 5 years is a 24.6% IRR, 3x in 10 years is 11.6%. Investors use MOIC for quick sizing and IRR for comparing against time-adjusted alternatives. Model both on the ROI calculator.
What is a good MOIC for a venture investment?
For a single early-stage check, funds underwrite to 10x+ potential because the power law means most bets return little. At the fund level, roughly 3x net MOIC over the fund's life is the classic success bar, requiring 4-5x gross before fees and carry.
How do I convert MOIC to IRR?
For a single investment returned in one exit: IRR = MOIC^(1/years) - 1. Examples: 2x in 3 years is 26%, 5x in 6 years is 30.8%, 10x in 7 years is 38.9%. Multiple cash flows in and out need a proper XIRR computation, which is what spreadsheet XIRR functions and the calculator handle.
Why do VCs need 10x outcomes if funds only target 3x?
Portfolio math. In a typical seed portfolio, half the companies return near zero and a few return 2-3x. For the whole fund to net 3x, the one or two winners must return the entire fund alone, which means every check has to be capable of 10-50x, even though most will not get there.
What are TVPI and DPI?
Fund-level cousins of MOIC. TVPI = total value (realized + unrealized) divided by paid-in capital. DPI = actual cash distributed divided by paid-in. A fund can show 3x TVPI on paper marks with only 0.5x DPI in real cash, which is why experienced LPs say DPI is the metric that matters.
Does this math change what valuation I should raise at?
Directly. Your post-money valuation sets the exit your investor needs: at $20M post, a fund's 10x test implies a credible $200M+ path. Raising at the highest possible number can price you out of the very investors you want. Sanity-check with the valuation calculator before you anchor.
Which investors accept lower multiples than VCs?
Angels investing their own money, family offices without fund clocks, and revenue-based financiers can all be happy with durable 3-5x outcomes. If your business is strong but not power-law shaped, target them instead of forcing a venture narrative. Filter by investor type on Round Funded.
Final Word
MOIC tells you how big, IRR tells you how fast, and the power law tells you why your seed investor needs to believe in 10x. Founders who run this math before the raise pick the right investors, the right valuation, and the right story.
