How Much Equity Does YC Take?
Y Combinator takes 7 percent of your company for $125,000, and invests another $375,000 on an uncapped SAFE with an MFN clause that converts at your next round's price. That is the whole standard deal: $500,000 for roughly 9 to 10 percent at the $15M cap YC uses in its own example, identical for every company and funded the day you are accepted, verified against ycombinator.com/deal on September 25, 2026. This guide walks the exact math, and you can compare YC against every other program in the SF accelerator directory.
The deal is non-negotiable and has been the same $500,000 since January 2022. What varies is what it costs YOU, because the MFN piece depends entirely on how the post-money SAFE converts at your next round's valuation.
How Much Does YC Give for 7%?
YC gives $125,000 for 7 percent, and that is the only part of the deal priced as a fixed stake. The other $375,000 buys no fixed percentage: it sits on an uncapped SAFE with an MFN clause and converts at whatever price your next round sets, so YC's total ownership lands near 9 to 10 percent at a $15M cap and lower at a higher one.
The Two SAFEs, Explained
YC's $500K arrives as two simultaneous instruments plus a YC Agreement:
- The $125K SAFE: converts into a fixed 7 percent of your company in your first priced round, calculated after all SAFEs convert and including the option pool.
- The $375K MFN SAFE: uncapped, with a Most Favored Nation clause. It converts at the terms of the lowest-cap SAFE (or best terms) you issue between the batch start and your priced round. In plain words: it gets the same deal as your next investors.
- The YC Agreement: gives YC pro rata rights, meaning the right to invest more in your future rounds to maintain its ownership. YC has followed on with millions in many portfolio companies.
There are no program fees, and YC states it avoids downside-protection terms like enhanced returns in low exit scenarios. When comparing accelerator offers, subtract any fees a program charges from its headline check.
The Worked Example: What YC Owns After Your Seed
YC's own illustration uses a $15M post-money cap on your next SAFEs:
| Instrument | Amount | Converts to |
|---|---|---|
| Fixed SAFE | $125,000 | 7.0% (fixed) |
| MFN SAFE at $15M cap | $375,000 | $375K / $15M = 2.5% |
| YC total (pre-dilution) | $500,000 | ~9.5% |
Run the same math at other caps and the trade becomes visible:
| Your next round cap | MFN converts to | YC total (approx) |
|---|---|---|
| $8M | 4.7% | ~11.7% |
| $15M | 2.5% | ~9.5% |
| $25M | 1.5% | ~8.5% |
| $40M | 0.9% | ~7.9% |
The pattern: the stronger your company, the cheaper YC gets. A breakout company gives up barely more than the fixed 7 percent; a company that raises at a modest cap gives up meaningfully more. Sanity-check your own cap scenario with the valuation calculator before you anchor a number.
One more mechanic worth knowing: in the priced round itself, the new money and the option pool increase dilute everyone, including YC. That is why YC's real ownership at Series A is usually below the headline figures above, unless it exercises pro rata.
Is 7 Percent Expensive? The Honest Comparison
| Program | Deal | Implied cost |
|---|---|---|
| Y Combinator | $500K for ~7% + MFN | The most expensive check, the strongest brand |
| Techstars | ~$120K for 6% | Less capital per point of equity |
| Antler | ~$100K for ~9-10% | Pre-team, pre-idea stage, different product |
| MassChallenge | Cash prizes, 0% | Zero equity, zero YC-style signal |
Read as pure price-per-percent, YC is not the cheapest. Read as what founders actually buy, the calculation changes: YC's badge measurably moves seed valuations, Demo Day compresses months of fundraising into a week, and the alumni network functions as permanent distribution. Our Antler vs YC comparison covers when each program wins.
When YC is worth it: first-time founders, founders without US networks, and anyone whose next round would price below roughly $15M without the badge.
When it is not: repeat founders with investor relationships who can raise a priced seed on traction alone. If your round clears $20M+ without YC, even the roughly 8.5 to 9 percent YC would hold at that cap is the most expensive money you will ever take. Many strong teams raise directly from the top seed funds instead.
What Else the $500K Buys
The equity pays for more than capital, and pretending otherwise makes the math dishonest:
- A dedicated YC General Partner per company, each a former founder, in a direct Slack channel with weekly meetings during the batch.
- The batch structure: 3-day in-person kickoff in San Francisco, weekly small-group dinners, speakers like the founders of OpenAI, Airbnb, and DoorDash.
- Demo Day: a pitch to a curated audience of over a thousand investors.
- The alumni network: thousands of YC founders who preferentially buy from, hire from, and invest in each other, for the life of your company.
- Incorporation help: YC invests in US, Canada, Cayman, and Singapore entities and walks foreign companies through the flip.
Raising Around the YC Deal: Where Round Funded Fits
Whether you take the deal or not, the next step is identical: a systematic raise. YC companies still run outreach before Demo Day to warm the room; non-YC companies replace the badge with pipeline volume.
Round Funded runs that pipeline: a database of 60,000+ active investors filterable by stage, sector, and geography, AI-drafted personalized outreach from your own Gmail, and open and reply tracking. The badge accelerates a raise; it has never replaced one.
Applying founders also get YC Insights: application-style answers, batch data, and founder profiles for 5,900+ Y Combinator companies, a cheat sheet for seeing how accepted companies in your sector pitched before you write your own application; the reconstructed Dropbox and Coinbase applications are a good place to start, and the YC top companies list shows which alumni the 7 percent bought into.

How to Decide on the YC Deal: Step by Step
- Benchmark your alternatives in the Round Funded directory: know what Techstars, Antler, and the vertical programs offer before treating YC's terms as the only option.
- Model your realistic next-round cap with the valuation calculator, then compute the MFN conversion at that cap. That number, not 7 percent, is YC's real price.
- Price the badge against your network. No US investor relationships: the badge is worth multiples of its cost. Warm access to 20 seed funds: it may not be.
- Test the direct-raise path in parallel: run outreach to 50 stage-matched funds through Round Funded while your application is pending; investor responses are real market data on what you would raise at without YC.
- If accepted, take the money immediately. It funds at acceptance, there are no milestones, and negotiating is not a thing; the deal is standard by design.
- If you pass or are rejected, redirect fully to the direct raise; the rejection playbook covers the mechanics.
Frequently Asked Questions
What percentage of equity does Y Combinator take?
A fixed 7 percent for $125,000, plus a $375,000 uncapped MFN SAFE that converts at your next round's terms. At a $15M post-money cap the MFN adds about 2.5 percent, so YC holds near 9.5 percent before later rounds dilute it. Run your own cap through the cap table calculator.
Does YC take equity?
Yes, always. Every accepted company gives YC 7 percent for $125,000 on a post-money SAFE, plus whatever the $375,000 MFN SAFE converts to later. There is no fee-only or equity-free option, no negotiation, and no milestone: the terms are public, identical across batches, and committed the day you are accepted.
How much does YC invest?
$500,000 per company, since January 2022: $125,000 for 7 percent plus $375,000 on the uncapped MFN SAFE. Before 2022 the check was $125,000 for 7 percent alone. The money is committed at acceptance, not at batch start, and YC also gives each company access to $12M+ in partner credits and deals.
What is the YC standard deal?
The YC standard deal is $500,000 for every accepted company: a $125,000 post-money SAFE converting to 7 percent, a $375,000 uncapped SAFE with an MFN clause, and a YC Agreement granting pro rata rights in future rounds. The same terms apply to every company in every batch, whether incorporated in the US, Canada, Cayman, or Singapore.
What valuation does the YC deal imply?
The fixed piece prices the company at about $1.79M post-money ($125,000 for 7 percent). The $375,000 MFN piece has no cap, so it inherits the valuation of your next SAFE round instead. Founders accept the 7 percent for the badge, not the price; compare it with what the top seed funds pay for the same stake.
What is an uncapped MFN SAFE?
A SAFE with no valuation cap and a Most Favored Nation clause: it automatically adopts the best terms (lowest cap or biggest discount) of any SAFE you issue afterward. YC's $375K therefore converts on the best terms any of your next SAFE investors get, never worse than them.
Is the YC deal negotiable?
No. The $500,000 standard deal ($125,000 for 7 percent plus the $375,000 MFN SAFE) is identical for every company in every batch, which YC treats as a feature: no negotiation, no founder gets a worse deal than another, and the terms are public. What varies is only how the MFN piece converts, which your next round's valuation determines.
Does Y Combinator charge any fees?
No. YC charges no program fees on its $500,000 investment, so the full $500,000 reaches the company, and it states it avoids "gotcha" terms like enhanced returns in downside exits. When comparing accelerators from the directory, subtract any participation fees from a program's headline investment to see the real check.
Is Y Combinator worth 7 percent?
For first-time founders and anyone without US investor networks, usually yes: the badge lifts seed valuations, Demo Day compresses the raise, and the alumni network compounds for years. For repeat founders who can raise a $20M+ priced seed directly from top seed funds, the math often says no.
Final Word
YC's price is not 7 percent; it is 7 percent plus whatever the MFN converts at, which your own next round decides. Strong companies pay barely above the floor, modest rounds pay double digits. Run the math at your realistic cap, price the badge against your actual network, and make the call with numbers instead of folklore.
