About EveryFix

Our Mission

EveryFix exists to make everyday math and planning easier. Whether you're estimating how much paint to buy, figuring out a mortgage payment, checking your BMI, or converting a recipe measurement, EveryFix gives you a fast, no-nonsense answer without needing to create an account, download an app, or dig through ads to find a working calculator.

The idea started from a familiar frustration: searching for a simple calculator and landing on a page that buries the actual tool under pop-ups, forced sign-ups, or five paragraphs of filler before you can type in a single number. EveryFix is our answer to that — the tool is front and center on every page, and the explanation is there if you want it, not in the way if you don't.

What Makes EveryFix Different

EveryFix is not just a calculator website — it's a growing platform of 109+ tools spanning calculators, unit converters, estimators, generators, and planning checklists across ten categories, including Home & Garden, Construction, Finance, Auto, Health, Business, Travel, and more. We built it with three principles in mind:

• Speed. Every tool is lightweight and loads quickly, with no unnecessary scripts slowing you down.
• Privacy. All calculations run locally in your browser. We never see or store the numbers you type in.
• Clarity. Every tool includes a plain-English explanation of how it works and the formula behind it, not just a black-box result.

How We Write and Fact-Check Our Content

Every formula, worked example, and explanation on EveryFix is written to be genuinely useful on its own, not just text stacked around a widget. Our editorial process has three steps for every tool and guide:

• Source the formula. We start from the standard, well-established formula for the calculation — the same amortization formula lenders use, the Mifflin-St Jeor equation clinicians use for BMR, the IRS's published tax brackets — not an approximation we made up.
• Work a real example, by hand. Every "how it works" guide includes at least one fully worked, specific example with real numbers, calculated step by step and independently checked for arithmetic accuracy before publishing.
• Review for accuracy and plain language. Before anything goes live, we check that the numbers are correct, the units are consistent, and the explanation would make sense to someone doing this for the first time — not just to someone who already knows the topic.

Where a topic touches health, finance, or tax outcomes, we say so plainly: our tools and guides are educational estimates meant to help you understand and plan, not a substitute for a doctor, financial advisor, accountant, or attorney. See our disclaimer for the full picture, and reach out any time you spot something that looks off — we want to know.

How EveryFix Is Built

EveryFix is a static website built with modern web technology (Next.js, React, and TypeScript) and hosted on Cloudflare's global network for speed and reliability. There is no login system, no database, and no paid third-party APIs — every calculation you see is computed instantly in your own browser using straightforward, well-documented formulas.

Because everything runs client-side, none of the numbers you enter — your income, your weight, your loan amount, anything — ever leaves your device or touches a server we control. That is a deliberate design choice, not a marketing line: there is simply no back end for that data to go to.

How EveryFix Is Funded

EveryFix is free to use, with no account, subscription, or paywall of any kind, and we intend to keep it that way. Like most free content sites, we support the cost of building and hosting EveryFix through advertising. Ads are clearly separated from tool content and never block or interfere with a calculator itself — you can always see and use the full tool without interacting with an ad.

What's Next

We're actively expanding EveryFix with new calculators, converters, and planning tools across every category, along with deeper how-to guides behind the most-used tools. Have an idea for a tool you'd like to see, or found a number that looks wrong? We'd genuinely love to hear it — get in touch.
