Market & tariff

Choose your label market and enter the electricity price from your bill.

For example, 20 cents/kWh is 0.20 USD/kWh. Use your own bill rate.

Remembering takes effect when you select Apply tariff.

Changing market selects a currency and clears the draft price for you to enter. Currency changes do not convert prices. Your remembered market sets the label reader's starting market; shared examples keep their own inputs. Separate scenario rates stay as entered.

Manage saved data

Clearing removes saved market, tariff, scenarios and measurement observations. Export journal records you want to keep first. Analytics choices are managed separately in the footer.

Results are the values shown when each scenario was saved. They do not update if your tariff changes; reopen a scenario to recalculate. Saved scenarios live in this browser only and disappear if you clear site data. How device storage works
