Base-case interpretation
At a 4.0× revenue multiple, the illustrative pre-money valuation is $4,800,000. Raising $1,000,000 implies approximately 17.2% investor ownership before option-pool, convertible, SAFE, transaction, and other financing adjustments.
What this tool does
It turns your revenue and multiple assumptions into pre-money, post-money, investor ownership, and founder dilution scenarios.
What it does not do
It does not select a defensible market multiple, review evidence, model option pools or convertibles, or provide a formal valuation.
Illustrative planning output only. Results depend entirely on the assumptions entered and do not represent current market multiples, a formal valuation, or professional advice.
Worked example
A $1.0M round on $1.2M annualized revenue.
Using illustrative 2.5×, 4.0×, and 6.0× revenue multiples produces pre-money values of $3.0M, $4.8M, and $7.2M. The base case produces a $5.8M post-money valuation and approximately 17.2% investor ownership before other financing adjustments.
| Case | Multiple | Pre-money | Post-money | Investor ownership |
|---|---|---|---|---|
| Downside | 2.5× | $3.0M | $4.0M | 25.0% |
| Base | 4.0× | $4.8M | $5.8M | 17.2% |
| Upside | 6.0× | $7.2M | $8.2M | 12.2% |
Method
What the calculator is doing.
1. Pre-money
Annualized revenue × selected revenue multiple
2. Post-money
Pre-money valuation + proposed funding
3. Ownership
Investment ÷ post-money valuation, then applied to current founder ownership
The multiple is an assumption, not a market fact.
Relevant multiple evidence depends on the business model, sector, recurring revenue quality, growth, margins, retention, customer concentration, capital needs, stage, geography, market conditions, and comparability. The default values are illustrative so the calculator works immediately; they are not claims about current market pricing.

FAQ
Startup valuation calculator questions.
How does the Startup Valuation calculator work?
It multiplies annualized revenue by the downside, base, and upside revenue multiples you enter. It then adds the proposed funding to calculate post-money value and divides funding by post-money value to estimate investor ownership.
What is pre-money valuation?
Pre-money valuation is the illustrative value of the company immediately before the new financing is added.
What is post-money valuation?
Post-money valuation equals pre-money valuation plus the new capital invested.
How is founder dilution calculated?
The calculator applies the new investor ownership percentage to the current founder ownership. The difference between current founder ownership and founder ownership after the round is shown as founder dilution in percentage points.
Does the calculator choose the right revenue multiple?
No. You choose the illustrative multiples. A defensible multiple requires evidence about the company, sector, growth, margins, traction, market conditions, risk, and comparable companies or transactions.
Is this a formal or certified valuation?
No. It is an educational planning tool, not a certified appraisal, fairness opinion, investment recommendation, or formal valuation.
Are my financial inputs sent to Fundamod?
No. The calculator performs the calculations in your browser and does not submit the financial inputs to Fundamod.
