UtilityForge is a collection of free, browser-based calculators and reference tools built for professionals and everyday users who need accurate answers quickly. Every tool runs entirely client-side — no account, no sign-up, and no data sent to a server.
My name is Stephen Milner. I'm a software developer based in the UK. I built UtilityForge because I kept running into the same problem: searching for a specific calculator or reference tool and landing on pages that were either inaccurate, cluttered with dark patterns, or required an email address to see a result.
Each tool on this site is something I needed to use myself, or something I built after someone I know described the same frustration. The site started in 2025 and has grown to cover tax, shipping, privacy, compliance, and finance topics.
Before publishing a tool, I research the underlying rules carefully. For tax calculators, that means reading the relevant IRS publications, state tax authority guidance, or HMRC documentation directly, then cross-referencing against at least two independent sources. Rate tables and thresholds are updated when official rates change. Each tool page documents the data sources used and when the content was last reviewed.
The tools are built in React and TypeScript, compiled to static files, and deployed on Cloudflare Pages. Because everything runs in your browser, there is no server that can log what you calculate. I have no access to the numbers you type in.
I take accuracy seriously and update tools when rules change. That said, every tool on this site is for estimation and reference purposes. Tax law is complex and varies by individual circumstances. Shipping costs depend on carrier agreements and surcharges that change frequently. Compliance requirements in areas like EU sanctions or AI Act classification should always be verified against current official guidance.
None of the tools on this site constitute legal, financial, or professional advice. For decisions with significant consequences, consult a qualified professional.
UtilityForge is supported by display advertising served by Google AdSense. Ads are clearly separated from tool content. I do not sell, share, or collect user data beyond what is described in the Privacy Policy.
