Corrections policy
If a number here is wrong, we want to know. Email corrections@watt-dollar.com.
What helps
- The page address, and the figure you think is wrong.
- What you believe the right figure is, and where it comes from — a bill, a nameplate, a meter reading, a published source.
- The inputs you had on screen, if the figure came from the calculator. The "Copy share link" button captures them exactly.
What we do
- Acknowledge. We aim to reply within five working days.
- Reproduce. A figure is only wrong if we can make it wrong; if we cannot reproduce it we will say so and ask for more detail rather than closing it.
- Classify. A calculation error, a stale or mis-sourced input, or unclear wording each get a different fix.
- Correct. Calculation and data errors are fixed at the source and republished, which updates every page that draws on them. Wording is amended in place.
- Record. A correction that changes a published figure updates the page's review date, and material corrections are noted on the page itself rather than silently overwritten.
What is not a correction
A figure differing from your bill is usually not an error in the arithmetic: the site's default prices are regional averages, and its default usage is a typical pattern, neither of which is yours. Enter your own per-kWh price and your own usage first. If it still disagrees, tell us — that gap is exactly what we want to hear about.
