How this startup valuation calculator works
The calculator takes five inputs: annual recurring revenue, month-over-month growth rate, investment stage, sector, and gross margin. From those it produces a pre-money valuation range using the methods venture investors actually reach for at each stage.
For seed, Series A, and Series B companies with revenue, the ARR multiple method multiplies annual recurring revenue by a stage-appropriate multiple: typically 3 to 8 times at seed, 8 to 15 times at Series A, and 12 to 20 times at Series B. The multiple is then adjusted by three factors. Sector applies a premium or discount (AI and machine learning carry the largest premium, consumer and marketplace businesses the largest discount). Growth above 10 percent month over month adds a bonus, and growth above 20 percent adds a larger one. Gross margin above 75 percent adds a bonus, while margin below 50 percent applies a discount.
The market comparables method runs for every stage. It starts from the typical valuation band for that stage and applies the same sector and growth adjustments, which makes it useful when revenue is small or lumpy and an ARR multiple would understate the company.
For pre-seed companies the calculator adds a Berkus method estimate. The Berkus approach values a pre-revenue startup by assigning a dollar amount to each of five risk-reducing factors: a sound idea, a prototype, a quality management team, strategic relationships, and early product rollout or sales. Because it does not depend on revenue, it is the standard way to talk about value before the first dollar of ARR.
Typical pre-money valuation ranges by stage in 2025 and 2026
Round sizes and valuations have widened over the past two years. AI companies raise at the top of every band, while most other software companies price closer to the middle. The ranges below are typical for US and Western European venture rounds; individual deals fall outside them in both directions.
| Stage | Typical pre-money | Typical round size | What investors price |
|---|---|---|---|
| Pre-seed | $1M to $5M | $250K to $1.5M | Team, market size, prototype, early signals |
| Seed | $5M to $15M | $1M to $4M | Early product-market fit, first revenue, retention |
| Series A | $15M to $50M | $5M to $15M | Repeatable growth, ARR typically above $1M, unit economics |
| Series B | $50M to $150M+ | $15M to $40M | Scaling proof, efficient growth, path to profitability |
Ownership sold per round typically sits between 10 and 25 percent. If the calculator's range implies selling much more than that to raise the amount needed, the round size, not the valuation, is usually the number to revisit.
What moves a valuation up or down
Team. Repeat founders, founders with deep domain expertise, and teams that have already worked together raise at a premium at every stage. At pre-seed the team is most of the valuation.
Traction. Revenue growth rate matters more than revenue level. A company growing 15 percent month over month at $500K ARR will typically be valued above a company at $1M ARR growing 3 percent. Net revenue retention, gross margin, and payback period carry the most weight from Series A onward.
Market. Investors underwrite the size of the outcome, so a credible path to a large market lifts the range even before the numbers prove it. Sector sentiment shifts year to year; AI infrastructure and vertical AI have carried a premium through 2025 and 2026, while consumer and marketplace deals have priced more conservatively.
Terms and competition. A headline valuation with a large liquidation preference, participating preferred stock, or heavy warrant coverage is worth less than a lower valuation on clean terms. The single biggest driver of a strong price is more than one interested investor, which is why running a tight process with a targeted list matters more than any spreadsheet.
How investors actually decide
Most venture investors do not calculate a valuation from first principles. They start from the ownership they need, typically 10 to 20 percent for a lead, divide the check they want to write by that ownership, and then check the implied valuation against comparable rounds they have seen in the same stage and sector. The calculator's market comparables method mirrors that habit.
That means the right investors for a round are the ones already writing checks at the stage and in the sector in question. VCSift lists more than 410,000 venture investors, angels, and family offices searchable by stage, sector, and country, so a founder can build a target list of seed investors or Series A investors whose recent deals match the valuation the calculator suggests.
Once the range and the list are set, the remaining work is the pitch. The free investor outreach email generator drafts the first message, and the pitch deck checklist covers the slides investors expect to see before they will discuss price.
