Ryan Clarke

Ryan Clarke is a software engineer who started QuickUse Calculator out of a long-running frustration with the existing options online: tools that round in the wrong place, calculators that quietly fall back to last year's tax tables, sites that look authoritative but cite nothing. The site is the answer to that frustration — a research-quality reference with a paper trail.

The technical side of the project is squarely in his wheelhouse: decimal-precision math (never floating-point for money), versioned regulatory tables with verification dates, automated tests that compare every calculator against its underlying authoritative source, a build pipeline that surfaces stale data before it reaches the index. He writes the personal-finance explainers and pillar guides under his byline and contributes to the editorial review of the broader catalog.

For posts on regulated topics where being wrong has financial consequences for the reader, Ryan defers to the QuickUse editorial team handles for review and co-byline. He is not a CFP or CPA, and the "When NOT to use this calculator" section on every page surfaces the specific edge cases where calculator output stops being a useful approximation. We expect readers to consult a credentialed professional for material decisions.
