The Calc.Cards Editorial Team

Last updated 2026-05-18

Calc.Cards is published by Wilcoe, an independent studio focused on calculator and decision-support tooling. Wilcoe's editorial team is responsible for every calculator on this site: choosing what to build, sourcing the underlying formula, verifying the math, writing the article, and signing off before publication. The byline "Reviewed by Calc.Cards Editorial Team" on every page is Wilcoe's name on the work.

We're a small team and we work directly. There's no editorial committee, no rotation of freelance authors, and no syndicated content. Everything that ships under this byline was built, reviewed, and approved by the people listed below before it went live.

Who we are

Wilcoe's editorial team brings together engineering and domain-research backgrounds. Rather than naming individual editors publicly โ€” the team is small and we're selective about public-facing exposure โ€” we've described the roles and the standards each one holds the work to. If you want to reach a specific person about a specific calculator, email hello@calc.cards and we'll route you.

  • Editor-in-Chief. Sets the editorial standard, approves new calculators before they enter the public catalog, owns the byline and the last-updated date on every page, and is the named point of contact for corrections.
  • Formula reviewers. Domain-knowledgeable team members (finance, health, construction, math) who verify the formula against the cited primary source and check at least one worked example end-to-end before sign-off.
  • Build engineers.Implement the calculator widget, test the math against benchmarks, and ship the page. The widget is built once per calculator and runs entirely in your browser โ€” inputs never leave your device.

The editorial process

Every calculator on the site follows the same four-step pipeline before it goes live. We described this on the About page in summary; this is the longer version.

1. Source the formula

We don't use generic blog posts as the source of authority. For finance, the source is the standard formula plus the official agency guidance (Consumer Financial Protection Bureau, IRS publication, HUD loan-limit table, Freddie Mac rate survey, etc.). For health, the source is the published equation (Mifflin-St Jeor, Watson, CDC pediatric growth chart, etc.) and the relevant clinical society's interpretation guidelines. For construction, the source is the conventional unit-conversion formula plus the relevant code requirement when applicable. The primary source is cited at the bottom of every calculator page.

2. Build the widget

The interactive calculator is implemented once per page. It runs entirely in the browser; we don't collect or store the numbers you type. Each widget is tested against at least one published worked example or an official-agency table. If the calculator returns a different answer than the source we're calibrating against, we don't ship until the discrepancy is reconciled.

3. Write the article

Each calculator ships paired with a 1,000โ€“4,500 word article. The article's job is to give you enough context that you could follow the math without using the widget โ€” the widget just does it faster. Articles include: a plain-English explanation of what the calculator does, how to interpret each input, the formula with a step-by-step worked example using realistic numbers, the practical traps and edge cases a first-time user runs into, and an FAQ covering the questions readers actually ask.

4. Editorial review

Before publication, an editor cross-checks the formula implementation against the cited source, walks through the worked example end-to-end, and reads the FAQ against the kinds of questions a non-expert would ask. The byline "Reviewed by Calc.Cards Editorial Team" on a page is the formal sign-off; the "Last updated" date is when that review last re-ran. We do not touch the last-updated date for cosmetic edits โ€” only when the math, a cited number, or the substance of the explanation changes.

How we use AI

We use AI assistance in the drafting phase the same way a small newsroom uses a research assistant: to pull together candidate phrasings, surface adjacent questions a user might have, and propose article structure. Every page is then edited by a human, has its math verified against a primary source, and carries the editorial sign-off.

AI is never the source of authority for a calculation. The formula, the numeric thresholds (BMI cutoffs, IRS contribution limits, FHA loan limits, conventional PMI rules, etc.), and the cited references on each page come from the underlying agency, journal, or textbook โ€” not the model. If you find a discrepancy between what an AI tool tells you and what a Calc.Cards calculator says, the calculator's number is what we're willing to defend in writing; please email us if it looks wrong.

Editorial standards

A handful of rules we hold every page to:

  • Show the formula.Every calculator article includes the underlying formula in readable form โ€” not just the answer. If you can't reproduce our number with the formula and your inputs, the page is wrong and we want to know.
  • Cite primary sources. Numeric thresholds and rate data come from a named agency or journal, not from another blog. The source list is at the bottom of every page.
  • Distinguish estimate from advice. Calculator results are educational estimates, not professional advice. Every page in the finance and health categories carries that disclaimer in the article and again in the FAQ.
  • Date every page.Each page shows when it was last reviewed. If you're reading a finance page where the last-updated date is more than a year old, the rate or contribution-limit data may have moved; check the cited source.
  • Correct openly.When we publish a correction, the last-updated date moves, and the change is reflected directly in the article rather than appended as a separate note. We'd rather the page be right today than have an audit trail of previous mistakes.

Corrections and accountability

If you find a formula error, a wrong cited number, a misleading worked example, or a mistake in an FAQ answer, please email hello@calc.cards with the calculator URL and what looks wrong. Verified corrections land on the page within a few business days, with the last-updated date moved to reflect the change. We don't maintain a public corrections log; the change is in the article itself.

For broader feedback โ€” about an entire category, the methodology page, or a calculator we don't publish yet but should โ€” the same inbox works. Replies come from a person on the editorial team, usually within one or two business days.

What we publish and what we don't

As of the last update to this page, Calc.Cards publishes 395 calculators across 19categories. We add new calculators when a reader request hits a threshold of interest or when we identify a useful tool that isn't well covered elsewhere on the web.

We do not publish:

  • Clinical-decision tools that require a licensed professional's judgment (specific drug-dosing calculations for individual patients, for example).
  • Tax-return calculators that promise to replace a CPA. We publish general estimators (income tax, capital gains) and link the IRS primary source; we don't file returns.
  • Calculators tied to a specific product or vendor. If a tool is useful only because it routes to a single lender or affiliate, it's not editorially independent and we don't publish it.
