What a 409A valuation costs a US startup, how many you actually have to buy, and which prices are published rather than guessed.
What is on this site
One question, "409a cost", answered with a calculator that works on the page with no account, 4 guides on the questions around it, a data table you can cite (the figures and their method), and the sources every figure rests on.
- 409A valuation cost: published prices and price drivers: Nobody publishes a market rate for 409A valuations. Here are the list prices three providers publish today, checked 15 August 2026, and the factors that move a quote.
- 409A valuation requirements: what section 409A asks of a startup: 409A valuation requirements in plain terms: a reasonable valuation method, the three safe harbor presumptions, the 12-month limit, and the 20 percent additional tax.
- When do you need a new 409A valuation?: Two triggers matter: the 12-month age limit on the safe harbor appraisal, and any material event that makes an earlier calculation unreliable. What counts as material.
- 409A valuation example: what a report contains, and why no calculator: What an appraisal actually works through, why the regulation asks for a method rather than a formula, and why no 409A calculator can produce a defensible number.
