CalcSmith author: who writes and checks the calculators
CalcSmith is written and maintained by one editorial desk — the CalcSmith team, operated by Jams. This page is the byline behind every calculator: who we are, how a page gets made, and how errors get fixed.
Who we are
CalcSmith is an independent web publication operated by Jams. There is no newsroom of forty and no content farm: a small desk researches each calculator, writes the page, and stands behind the numbers on it. You can reach the desk directly at contact@calcsmith.net or via the contact page.
How a calculator page is made
- The formula first. Every tool uses the standard formula lenders and textbooks use — amortized payments for loans, compound growth for savings, loan-to-value for PMI. If a formula is a convention rather than a law of arithmetic, the page says which convention and why.
- The worked example is recomputed independently. Before a page ships, its worked example is calculated again from scratch, outside the calculator's own code, and the two results must match to the cent.
- Automated math tests. The calculators' shared math core is covered by an automated test suite — 71 checks against independent calculations — that runs before publication. A failing check stops the release.
- Plain-language review. Each page is re-read for the only question that matters: could a first-time visitor follow the math and check the result themselves?
Corrections policy
If a reader reports an error, we reproduce it, fix it, and update the page — the "Last updated" date under the title changes with the fix. Errors in a worked example are treated as release-blocking bugs, not typos. Report one via the contact page with the calculator name and the numbers you entered.
What we are not
We are not lenders, brokers or financial advisors, and no page here is personal financial advice. More about the publication is on the about page.
