About MyCalcKit

MyCalcKit is an independent, free calculator site covering personal finance, health, and everyday math for the US, UK, Canada, and Australia. We built it because most calculator sites bury a simple tool under pop-ups, sign-ups, stale numbers, or only cover one country.

Our editorial standard

• Every tax, salary, and rate figure is sourced from an official body — the IRS, HMRC, CRA, ATO, GOV.UK, or a national statistics office — not copied from another calculator site.
• Every calculator page shows a "Last updated" date so you know exactly how current the figures are.
• We correct outdated figures as soon as we find them — if you spot one, tell us.

What we don't do

We don't require sign-up, store your inputs, or sell your data. Every calculation runs locally in your browser.
