Fridge Energy Cost Calculator

Work out fridge energy cost instantly with clear inputs, formula shown and shareable results.

About Fridge Energy Cost Calculator

A fridge freezer runs continuously, so its modest power draw accumulates into one of the larger appliance loads in a home. Efficiency has improved dramatically — a fifteen year old unit can use twice the electricity of a new one — but replacement payback is still usually a decade.

Formula

Fridge cost

annual cost = annual kWh x tariff; replacement saving = (old kWh - new kWh) x tariff

Worked example

With the default values below, Fridge Energy Cost Calculator returns Annual running cost of $70.00. Change any input above and every figure here is recalculated in your browser.

Assumptions and limits

  • The result is derived only from the 4 inputs listed above. Anything not among them is not part of the calculation.
  • In particular, this calculator does not take inflation, tax or fees or charges into account.
  • Figures are rounded for display to 4 decimal places, so totals built from several rounded parts can differ slightly from the unrounded arithmetic.

How these calculators are built and tested is described on the Methodology page. If a figure looks wrong, please report it.

Frequently Asked Questions

Does the energy label figure match reality?

Roughly, but ambient temperature and how full the appliance is both matter. A fridge in a warm kitchen or garage uses noticeably more.

What is the cheapest efficiency improvement?

Cleaning the condenser coils, checking the door seal and leaving a gap behind the unit for airflow. All are free and can cut consumption by 10-15%.
