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.

Read United States guidance

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.

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.

What does it cost to run?

Example inputs. Enter your label and tariff in the selected currency. Changing currency does not convert the price.

Estimated electricity cost

$73.00/ year

$6.08 per month · 365 kWh / year

$0.20 per day, averaged over 365 days

Your rate, your estimate
How we calculate this

365 kWh × $0.20 per kWh = $73.00 per year.

For cycle-based labels, we multiply energy per cycle by your weekly cycles and 52 weeks. Label tests may use a specific programme. Actual consumption can vary. Electricity only; water, detergent and other costs are excluded.

THE BIGGER PICTURE

A lower running cost.
But a better buy?

Compare the purchase price and electricity costs of two fridges over five years.

Annual electricity savings with B$23.00

What price difference can the savings cover?

Maximum extra price covered by B's electricity savings
$115.00
Break-even electricity rate
$0.173913 / kWh

At your entered tariff, B's electricity savings over 5 years cover up to $115.00 of extra purchase price. This is an electricity-only ceiling, not a product valuation or lifespan forecast.

At the break-even rate, purchase-plus-electricity totals match. Above it, B costs less over your chosen period; below it, A costs less. The displayed rate is rounded; period totals use full precision.

Estimates hold your tariff and consumption constant. Repairs, financing, disposal and resale value are excluded. This compares two purchase options.
