What it does
Utility Bill Calculator shows the whole calculation, not just the answer: every intermediate figure is on screen, so you can check it against your own numbers instead of trusting a single output box.
When you need it
Quoting, invoicing, or checking someone else's arithmetic — the moments where being roughly right costs money, and where the formula is easy to get subtly backwards.
Limits and caveats
Figures are unrounded until the final display, so results will not always match a calculation that rounded at each step. This is a working tool, not tax or financial advice, and local rules may differ. Everything happens in your browser, so the file never leaves your device.

Frequently asked questions
- Where do I find the price per unit?
- On the offer's summary sheet or the bill: add up the energy price and the per-unit network and system charges and excise. Comparison sites show the same all-in figure.
- Which VAT rate applies?
- 10% for household electricity and for gas up to 480 Smc a year; 22% above that and for businesses.
- Do my files get uploaded?
- No. This tool runs entirely in your browser, so the file never leaves your device.
