Are you wondering how to evaluate a equity in a job offer at a startup? Asking what is a 409A Valuation? Weighing 2 offers and want to make sure you are making the right decision? We’ve put together a job seekers guide to the 409A valuation
If you’re considering a role at an early-stage startup, chances are you’re being offered stock options as part of your compensation. That equity can be exciting, potentially life changing, but also come with very little information and could be extremely confusing. One of the most important questions your should be asking: What is a 409A Valuation (and how is it impacting my total compensation)?
This post breaks down what it is, why it matters, and how to use it to evaluate a startup equity offer to the best of your ability.
What is a 409A Valuation?
A 409A valuation is an independent appraisal of the fair market value (FMV) of a private company’s common stock. It’s named after section 409A of the tax code and is required by the IRS to set the strike price for your stock options.
It’s not the valuation you read about in TechCrunch or in a standard LinkedIn post after a company raises a round. That’s the preferred share valuation (what their VCs pay). The 409A valuation is focused on what the company’s common shares are worth and that’s what employees are typically granted when joining the company.
How does the 409A valuation affect my equity offer?
The 409A valuation determines how much you’ll pay to exercise your options. A lower 409A = a lower strike price = cheaper shares.
When you leave the company you have to come out of pocket and exercise your shares (purchase), so having this number be as low as possible is extremely important.
Say your offer includes 20,000 stock options at a $1 strike price (based on the 409A). If the company eventually sells or IPOs and shares are worth $20, that’s a potential $380,000 gain. ($20 – $1) × 20,000 shares = $380K.
Assuming you leave prior to a liquidity event, you would be spending $20k in order to purchase your shares, for the hopes of the larger return at a later date.
If the 409A was $5 instead? Your same options would cost you $100,000 to buy and be worth $300,000 net. Still meaningful, but a smaller spread and much higher initial risk.
So the 409A price at the time of your grant has a big impact on both your upside and how much capital you may need to exercise later.
How to Calculate Your Total Compensation (Including Equity)
When evaluating your offer, don’t just look at salary + bonus. Here’s how to estimate what your equity is worth:
1. Get the basics:
- Number of options you’re being offered
- The company’s total shares outstanding (to calculate your ownership %)
- The 409A valuation (this sets your strike price)
- The company’s most recent preferred valuation (to estimate potential upside)
2. Estimate value today (using 409A):
Let’s say you’re granted 20,000 options at a $1 strike price (409A), and the preferred share valuation is $8. While your common shares may not be worth that today, it gives you a directional benchmark.
3. Estimate value at exit:
Ask yourself: If the company exits at 10x today’s valuation, what’s my gain?
If your strike price is $1 and exit price is $20, that’s $19 × 20,000 = $380,000 in pre-tax potential upside.
Important: These numbers aren’t guaranteed, and exits may not happen or be way further down the line, or may be at a lower price, or you might only vest a portion of your equity. But this framework helps you compare offers and set expectations.

Key Questions to Ask Before Accepting an Equity Offer
Don’t be afraid to get specific. Founders and hiring teams should expect these questions from serious candidates.
About the equity offer:
- How many total shares are outstanding? (So you can calculate your percentage ownership)
- What’s the most recent 409A valuation? (To understand your strike price and equity cost)
- What is the exercise window for employees?
- When do you expect the next 409a valuation?
- What’s the founder’s exit-timeline thinking — IPO, acquisition, or no clear plan yet?
The company:
- When was your last fundraise, and at what valuation?
- How much runway do you have?
Future equity:
- Will I be eligible for additional grants over time?
- How is performance tied to future equity refreshers?
Frequently asked questions about startup equity and 409A valuations
What does a 409A valuation mean for me as a startup employee?
A 409A valuation is the IRS-mandated fair market value of a startup’s common stock — the same shares that get granted to employees through stock options. When you receive an equity offer, your stock options’ strike price is set based on the company’s most recent 409A valuation. In practice: a lower 409A at the time of your grant = a lower strike price = more upside for you if the company succeeds.
How do I calculate my value of my equity?
WithAgility has built an equity calculator tool that you can use to calculate the value of your stock options. If you are considering an offer with private RSUs, that calculation is a little more straight forward.
(Number of RSUs × current 409A valuation per share) ÷ vesting period in years = annual RSU value
Add that figure to your base salary to get a rough annual total comp number — useful for comparing offers head-to-head or against a quoted range.
Caveat: this is the paper value at today’s 409A. If the company exits at a higher valuation, the real number is bigger. If it never exits, the real number is zero. Use it as a comparison tool, not a financial plan.
How does the 409A valuation affect my stock option strike price?
Your strike price (the price you pay to exercise each option) is set equal to the 409A valuation per share at the time your options are granted. If the 409A is $1.50 per share when you start and the company eventually exits at $30 per share, your gain per option is roughly $28.50 (minus taxes). The lower the 409A at the moment of your grant, the bigger your spread when the company exits. This is also why joining a startup before a funding round usually beats joining after one — funding rounds typically trigger 409A re-valuations.
Is my startup equity actually worth anything?
Honestly, a lot startup equity ends up worth nothing. The base rate: roughly 10–30% of venture-backed startups return meaningful equity to employees, and even fewer return meaningful money to non-founding employees who hold a small percentage. When I help marketing leaders evaluate offers, I tell them to run the math assuming a 70–90% chance the equity is worth zero. Then ask whether the cash compensation alone is acceptable. If the answer is no, it’s usually a pretty telling answer. If the cash works on its own and the equity is upside, you’ve got a healthier offer to evaluate.
How do I know if my startup equity offer is fair?
Three reference points to anchor against: (1) percentage ownership — at pre-Series A B2B SaaS startups, founding marketers typically receive 0.25–1.5% depending on seniority and role; (2) strike price relative to recent 409A — granted at the existing 409A is standard, granted at a forward-looking 409A is worse, granted at the prior 409A (before a recent round) is a win; (3) vesting structure — 4-year vest with 1-year cliff is pretty much industry standard, but in the work we do everyday at WithAgility, we are seeing some companies get creative with vesting periods and exercise windows that are even more favorable to employees. Anything significantly more restrictive (longer cliff, longer vest, no acceleration on acquisition) is worth flagging.
What questions should I ask before accepting equity at a startup?
The five questions I’d put on every offer call:
- How many total shares are outstanding? (So you can calculate your percentage ownership)
- What’s the most recent 409A valuation? (To understand your strike price and equity cost)
- What is the exercise window for employees?
- When do you expect the next 409a valuation?
- What’s the founder’s exit-timeline thinking — IPO, acquisition, or no clear plan yet?
Most founders don’t volunteer these answers unless asked, and each one materially changes your equity’s expected value. If a founder refuses to answer any of them, that itself is a signal worth weighing.
What’s the difference between a 409A valuation and the preferred share price?
The preferred share price is what investors pay during a funding round; the 409A valuation is what the IRS says the common stock is worth. The 409A is typically 20–40% of the preferred share price — that “discount” reflects the lower rights of common stock (less liquidation protection, lower priority in a downside scenario). This gap is why your strike price is much lower than the post-money valuation suggests, and it’s the main mechanism by which employee equity gets its upside.
Can I negotiate my strike price or 409A valuation?
Not the 409A itself — that’s set by an independent appraiser and the founder can’t adjust it. But you can negotiate other equity terms: the grant size (number of options), the vesting schedule (not common but possible), the cliff length, and whether you get accelerated vesting on involuntary termination or acquisition.
How often does a 409A valuation change?
Per IRS rules, a 409A valuation must be refreshed at least once every 12 months OR after any “material event” — most commonly a funding round, but also major customer wins or losses, layoffs, restructuring, or significant new product launches. If you’re joining a company that’s about to raise (or has just raised), the timing of your equity grant relative to the new 409A can shift your strike price by 2–3x. Ask about the timing before signing.
What happens to my options if I leave the company?
Two windows matter: your vested options (the percentage you’ve earned through tenure) and your post-termination exercise window (the time you have after leaving to actually buy them). Industry-standard PTEW is 90 days — meaning after you leave, you have 90 days to write a check for the strike price on every vested option, or you forfeit them. Some progressive startups offer extended PTEW (1–10 years), which is an incredibly better option for candidates. Ask about PTEW before signing; if it’s 90 days and you can’t afford to exercise on departure, your “equity” is effectively much smaller than the headline grant suggests.
Final Thoughts
Equity can be a powerful part of your compensation, but you need to understand what you’re getting. The 409A valuation is your starting point for making sense of it.
Don’t be afraid to treat the job offer like a mini diligence process. It’s not just about the role, it’s about the upside, the risk, and how the team thinks about rewarding impact & transparency.
