Estimate monthly energy costs from pet heaters, fountains, lights, air purifiers, automatic feeders, and extra heating or cooling for pet comfort.
The result shows the direct electricity cost of pet devices plus extra climate cost. Long operating hours and inefficient heaters can quickly raise annual costs.
If you have multiple devices, enter combined wattage or run the calculator separately for each device.
A 45-watt device used 12 hours per day uses 16.2 kWh per month. At $0.16 per kWh plus $25 climate cost, total pet energy cost is about $27.59.
Electricity use depends on wattage and hours used. Multiply watts by daily hours and days, then divide by 1,000 for kWh.
Small devices usually add modest cost, but continuous use across many devices can create a noticeable monthly total.
Use wattage × hours per day × 30 ÷ 1,000 × electricity rate to estimate monthly device cost.
It can be significant because HVAC systems use much more energy than small pet appliances, especially in hot or cold seasons.
Use efficient devices, timers, smart plugs, and appropriate temperature settings while keeping your pet safe.
