A standard fridge uses 350-500 kWh per year. At 0.30/kWh that is 105-150 annually. Over 10 years, 1,500. An A-rated efficient model at 200 kWh saves roughly 90/year vs an older one — enough to pay for itself in 5 years on the premium. Running cost is often ignored when buying a fridge and is the larger number over the machine's life.
Run it with sensible defaults
Using annual consumption of 350, electricity rate per kwh of 0.3, the calculation works out to 105.00. Nudge the inputs toward your own situation and the output recalculates instantly. The defaults are meant as a starting point, not a recommendation.
The levers in this calculation
The inputs — Annual Consumption (kWh) and Electricity Rate per kWh — do not pull with equal force. Frequency and unit price pull the total in different directions. The biggest surprise for most people is how small recurring amounts compound into large annual figures — that's where this calculation earns its keep.
How the math works
Direct multiplication. Real usage can vary 10-20% based on ambient temperature, door openings, and age. The working is transparent — you can verify every step yourself in the formula section below. No black box, no opaque "proprietary model".
Why run the calculation
Utility bills creep. Small annual increases stack into meaningful differences over a decade. Running this once a year and switching providers when the gap widens is one of the easiest ways to keep household costs in check.
What this doesn't capture
Usage varies month-to-month; tariffs change; discounts come and go. The figure here is a clean baseline — your actual annual bill will fluctuate around it. Use the calculation to benchmark providers, not as a prediction of a specific bill.
