Are the home calculators free to use?
Yes. Every calculator on Laser Engravers Guide runs entirely in the browser, needs no account or email, and shows the full result without a paywall. Nothing you type is sent to us — the math happens on your device.
How accurate are the home calculators?
They use the published specifications and price ranges from our comparison data, with the same assumptions stated on each tool page. Results are estimates for planning, not a substitute for a site survey, a licensed installer or the manufacturer's own sizing table. Check the current spec sheet before you buy.
Can I link to a specific calculator instead of embedding it?
Yes — linking is always welcome and needs no permission. Each tool has a permanent page under /tools/ with the method and assumptions written out, so a link stays useful even if our embed programme changes.
