About TenKFact
Company numbers, cited to the 10-K
TenKFact started with a frustration Eric ran into while checking whether a company's share count had actually fallen after years of announced buybacks. The tools he found online were either buried behind paywalls, required sign-ups, or didn't explain their logic — just outputs with no methodology behind them.
So he built something better. TenKFact is a collection of free, no-account-required tools that give you the numbers a company filed with the SEC, each one tied to its XBRL tag and the filing it came from — and show you exactly how each answer was reached.
Eric builds free reference sites on public data and had grown tired of financial sites that show a tidy revenue chart with no way to tell which filing, which line or which restatement it came from. TenKFact reads the SEC's own structured filing data and prints the source beside every number, so a reader can check it instead of trusting it.

How it works
Every tool on TenKFact is grounded in a documented, citable method — a published formula, an authoritative standard, or a well-established model. We don't approximate or invent numbers. If we can't cite a primary source for the logic, we don't publish the tool.
The only source is the SEC's EDGAR XBRL data: the facts each company tagged in its own 10-K and 10-Q filings, republished by the SEC nightly. A number ships only with its tag and a link to the filing it was read from; where a company used a different tag or filed no value, the page says so rather than estimating.
Our commitments
- Free, no sign-up required. Every tool on this site is free to use with no account, subscription, or paywall.
- We show our work. Every tool explains its methodology, cites its sources, and surfaces assumptions — so you can verify the logic, not just trust the output.
- Honest about limitations. Where precision is limited or assumptions are required, we say so. Tools compute; they don't replace professional judgment.
- Kept current. Tools that use figures that can change over time carry a “last reviewed” date and are treated as an ongoing maintenance responsibility, not a one-time build.
