Startup Valuation: Methods and a Simple Calculator (2026)

Pre-money vs post-money: the distinction that changes your ownership

These two terms cause more founder confusion than any other part of a raise, and getting them wrong costs you equity.

Pre-money valuation is what your company is worth before the new money goes in. Post-money valuation is what it is worth after, so it includes the cash the investor just wired.

The relationship is one line:

Post-money = Pre-money + Investment

So if an investor offers "$2M on a $8M pre," the post-money is $10M, and they own $2M / $10M = 20% of the company. The reason the distinction matters: when someone quotes a valuation, always ask whether it is pre or post. A "$10M valuation" on a $2M raise means 20% dilution if it is post-money, but only $2M / $12M = 16.7% if that $10M was the pre-money figure. Same headline number, materially different ownership.

A quick gut-check table:

Term	What it means	Formula	In the $1M / $4M example
Investment	Cash raised this round	input	$1,000,000
Pre-money	Value before the round	post-money - investment	$4,000,000
Post-money	Value after the round	pre-money + investment	$5,000,000
Investor ownership	Equity the round buys	investment / post-money	20%
Founder dilution	Ownership you give up	same as investor ownership	20%

The simple startup valuation calculator (run it by hand)

Here is the original asset: a step-by-step calculator you can run on paper or in a spreadsheet. No widget required. You need two of the three core numbers (investment, pre-money, equity %), and everything else falls out.

Step 1: Pick your two known inputs

Usually you know the investment (how much you want to raise) and either the pre-money the market is suggesting or the equity % you are willing to sell.

Step 2: Solve for post-money

If you know the equity %:

Post-money = Investment / Equity %

If you know the pre-money:

Post-money = Pre-money + Investment

Step 3: Solve for the rest

Pre-money = Post-money - Investment Dilution (investor ownership) = Investment / Post-money

Step 4: New share price and share count

Valuations turn into shares. If your company has 2,000,000 existing shares before the round:

Price per share = Pre-money / Existing shares New shares issued = Investment / Price per share

Worked example: raise $1M at a $4M pre-money

Plug in the numbers:

• Investment = $1,000,000
• Pre-money = $4,000,000
• Post-money = $4,000,000 + $1,000,000 = $5,000,000
• Investor ownership / dilution = $1,000,000 / $5,000,000 = 20%

Now the shares, assuming 2,000,000 shares exist pre-round:

• Price per share = $4,000,000 / 2,000,000 = $2.00 per share
• New shares issued = $1,000,000 / $2.00 = 500,000 new shares
• Total shares after round = 2,000,000 + 500,000 = 2,500,000
• Investor ownership check = 500,000 / 2,500,000 = 20% (matches, good)

If you also set aside a 10% option pool post-round (created from the pre-money, the standard "pre-money pool shuffle" investors ask for), your founder ownership drops further because the pool is carved out before the investor's money goes in. That is a separate negotiation, but the calculator above is the foundation it sits on.

The reverse calculation: how much can I raise at a target dilution?

Founders often start from "I don't want to give up more than 15%." Flip the formula:

Maximum raise = (Dilution % / (1 - Dilution %)) x Pre-money

At a $4M pre-money and a 15% target: (0.15 / 0.85) x $4,000,000 = $705,882. So to stay at 15% dilution on a $4M pre, you raise roughly $706K, not $1M.

The five early-stage valuation methods (with real formulas)

Before a startup has revenue, you cannot multiply earnings, so investors fall back on structured frameworks. Here are the five most cited, each with its actual mechanic and a worked number. These produce ranges, and they disagree with each other on purpose; smart founders run two or three and triangulate.

1. Berkus method

Created by angel investor Dave Berkus for pre-revenue startups. It assigns a dollar value (commonly up to a fixed cap per element) to five risk-reduction milestones:

1. Sound idea (basic value)
2. Prototype (reduces technology risk)
3. Quality management team (reduces execution risk)
4. Strategic relationships (reduces market risk)
5. Product rollout or sales (reduces production risk)

Mechanic: assign each element a value up to your chosen cap, then sum them.

Worked example: with a $500K cap per element, a startup with a working prototype and a strong team but no sales might score $500K (idea) + $500K (prototype) + $400K (team) + $0 (relationships) + $0 (sales) = $1.4M pre-money. Change the cap and the whole valuation scales; this is why Berkus is a sanity range, not a precise figure.

2. Scorecard method (Bill Payne)

The Scorecard method compares your startup against the typical recently funded startup in your region and stage. You start from an average pre-money valuation for comparable deals, then adjust up or down across weighted factors.

Mechanic:

Adjusted valuation = Average comparable pre-money x Sum of (factor weight x your factor multiple)

The classic weightings Bill Payne published are roughly: strength of team (~30%), size of opportunity (~25%), product/technology (~15%), competitive environment (~10%), marketing/sales (~10%), need for more funding (~5%), other (~5%). For each factor you assign a multiple where 100% is "average," above 100% is "better than average," below is "worse."

Worked example (fill in your own comparable average): suppose comparable deals average a $3M pre-money. You rate your team at 150% of average, opportunity at 125%, product at 100%, competition at 100%, sales at 80%, funding need at 100%, other at 100%. The weighted sum:

Factor	Weight	Your multiple	Weight x multiple
Team	30%	1.50	0.450
Opportunity size	25%	1.25	0.3125
Product / tech	15%	1.00	0.150
Competition	10%	1.00	0.100
Marketing / sales	10%	0.80	0.080
Need for funding	5%	1.00	0.050
Other	5%	1.00	0.050
Total	100%		1.1925

Adjusted valuation = $3,000,000 x 1.1925 = $3.58M pre-money. Copy that table, drop in your own comparable average and multiples, and you have a defensible Scorecard number. The honest caveat: it is only as good as the comparable average you start from, and that number is hard to source and varies by year, sector, and geography.

3. Venture capital (VC) method

The VC method works backward from a future exit. The investor estimates what the company will sell for, divides by the return they need, and back-solves today's value.

Mechanic:

Post-money today = Projected exit value / Required return multiple Pre-money today = Post-money - Investment

Worked example: an investor projects a $50M exit in five years and wants a 10x return on this round. Post-money today = $50,000,000 / 10 = $5M. If they are putting in $1M, pre-money = $5M - $1M = $4M, and they need 20% of the company. (Note this lands on the same numbers as our by-hand example, which is not a coincidence; investors reverse-engineer the round to hit their ownership target.)

4. Comparables / multiples method

Once a startup has revenue, you can value it like a grown-up company: apply a multiple from comparable companies or recent transactions.

Mechanic:

Valuation = Revenue (or ARR) x Revenue multiple

Worked example: a SaaS startup with $1M ARR in a market where comparable companies trade at a 6x revenue multiple would be valued around $1,000,000 x 6 = $6M. The hard part is sourcing an honest multiple. Multiples move constantly with the market, vary widely by growth rate and sector, and public-company multiples rarely apply cleanly to a tiny private startup. Use a multiple you can actually defend with recent, comparable deals, not a number you read once.

5. What the round market actually sets (the real answer)

Here is the method that overrides all four above: the price is whatever a credible investor will pay, and what comparable startups raised recently at your stage in your geography. Methods give you a range to walk into the room with. Demand sets the price. A hot round with three term sheets prices above any formula; a cold round with one interested party prices below. This is not cynicism, it is how the market clears.

A summary of when to reach for each:

Method	Best for	Core input	Output type	Honest weakness
Berkus	Pre-revenue, idea/prototype stage	Milestone risk scores	Rough pre-money	Caps are arbitrary
Scorecard (Payne)	Pre-revenue angel rounds	Comparable average + factor weights	Adjusted pre-money	Needs a good comparable average
VC method	Rounds with a plausible exit story	Projected exit + target return	Pre/post-money	Exit and multiple are guesses
Comparables / multiples	Revenue-generating startups	Revenue + market multiple	Valuation	Multiples swing with the market
Round market	Every real raise	Investor demand + recent rounds	The actual price	Out of your direct control

The depth most calculators skip

Why two methods rarely agree, and what to do about it

Run Berkus and you might get $1.4M. Run Scorecard and you might get $3.58M. Run the VC method and you might get $4M. That spread is normal and it is the point. Take the range, anchor toward where comparable recent rounds actually cleared, and walk into negotiations with a band ($3M to $4.5M pre, say) rather than a single number. A founder who says "we are raising at a $4M pre, here is the comparable logic" is more credible than one who insists on a precise $4.17M.

The pre-money option pool trap

When an investor asks for a 15% to 20% post-round option pool "from the pre-money," that pool dilutes you, not them. It is carved out of the pre-money valuation before their dollars land. Always model the pool explicitly in your cap table; it can quietly cost you several points of ownership that no headline valuation reveals.

SAFEs and convertibles: valuation deferred, not avoided

Many early rounds use a SAFE or convertible note with a valuation cap instead of a priced round, which postpones setting a firm valuation until a later priced round. The cap is effectively a ceiling on the price the SAFE converts at. Understanding pre/post-money still matters because post-money SAFEs (the standard Y Combinator version) calculate the investor's ownership off the post-money cap, which changes your dilution math. For the canonical documents and the reasoning behind post-money SAFEs, see Y Combinator's official SAFE page. If you are working with one, our YC SAFE template guide walks through the mechanics.

Where this approach is NOT the best fit

This calculator and these methods are built for early-stage equity and convertible rounds. They are the wrong tool for valuing a profitable, cash-generating business, where discounted cash flow (DCF) and EBITDA multiples are the proper instruments. They are also poorly suited to deep-tech or biotech companies with a decade-long, binary path to value, where milestone-based and real-options valuation dominate. If you have steady profits or a regulatory-gated product, talk to a valuation specialist rather than relying on angel-stage heuristics. And to be explicit: nothing here is financial, legal, or tax advice. Every figure is a worked illustration.

When the number is set, share the round like a professional

A valuation is the start of a fundraise, not the end. Once you have a range, you are sharing a pitch deck and a data room with investors, and how you share them matters.

This is where Plox fits. Instead of emailing a deck as an attachment that you lose control of, you share it as a trackable link. The link never changes, so you can update the deck after you send it, and you see page-by-page analytics: who opened it, how long they spent on the traction slide, whether they finished. You get real-time notifications when an investor opens it, which tells you who is actually engaged before your next call.

Plox has a genuine free plan: secure links, analytics, and real-time notifications, no credit card, no time limit. For diligence, the paid tiers add AI-powered virtual data rooms with folders, dynamic watermarking applied per viewer, one-click NDA, and Ploxie AI that answers investor questions directly from your documents. There is a 14-day Data Rooms trial, and pricing is flat, published, and fully self-serve.

To be fair about the alternatives: DocSend pioneered deck analytics and remains a solid, widely trusted tool, especially for investors who already expect a DocSend link. Where Plox pulls ahead is the real free tier, the AI data room layer, and transparent self-serve pricing with no sales call.

For the full fundraising workflow, see our guide to sharing a pitch deck with investors and, once you are funded, our investor update template. For the bigger picture on keeping investors engaged across a raise, the Plox investor updates hub ties it together.

Frequently asked questions

Is a startup valuation calculator accurate?

No calculator produces an accurate price, and any tool that claims to is overselling. A startup valuation calculator does two honest things: it computes the cap-table mechanics exactly (post-money, pre-money, dilution, share price), and it produces a defensible range from structured methods. The actual price is set by negotiation and what comparable startups raised recently. Use the calculator to walk in informed, not to quote a single number.

How do I value a startup with no revenue?

Use qualitative methods built for pre-revenue companies. The Berkus method assigns dollar values to risk-reduction milestones (idea, prototype, team, relationships, sales). The Scorecard method starts from an average comparable pre-money and adjusts across weighted factors like team strength and market size. Run both, take the range, and anchor toward what comparable recent rounds actually cleared at.

What is the difference between pre-money and post-money valuation?

Pre-money is your company's value before the new investment; post-money is the value after, including the cash just raised. Post-money = pre-money + investment. The investor's ownership is always calculated off the post-money figure: investment / post-money. Always ask whether a quoted valuation is pre or post, because the same headline number produces different dilution depending on which it is.

How much equity should I give up in a seed round?

There is no universal rule, but founders commonly aim to keep dilution per round in a manageable band so that after multiple rounds they retain meaningful ownership. Work backward from a target dilution using maximum raise = (dilution / (1 - dilution)) x pre-money. The right answer depends on how much you need, your pre-money range, and investor demand, not a fixed percentage.

Do SAFEs have a valuation?

A SAFE defers the priced valuation but usually sets a valuation cap, which acts as a ceiling on the price at which the SAFE converts into equity in a later round. Post-money SAFEs, the standard Y Combinator version, calculate the investor's ownership off the post-money cap, so your dilution is more predictable but also locked in earlier. You still need to understand pre/post-money to model what a SAFE actually costs you.

Which valuation method do investors actually use?

Most early-stage investors use the VC method or comparables to set a target ownership, then let the round market (investor demand and recent comparable rounds) decide the final price. Methods give them a starting range; competition for the deal moves the number. That is why a founder with multiple term sheets prices above any formula and one with a single interested investor prices below.

When your valuation range is set and you are ready to raise, share your deck and data room through Plox as trackable links, watch who actually engages, and keep your investors updated as the round comes together. Start free, no credit card.
