- If the UPS runs all the time: 24 hours x 30 days = 720 hours
- If it runs only during work hours: 8 hours x 30 days = 240 hours
- Compute the monthly energy consumption:
Energy Consumption (kWh) = (Wattage × Usage Hours) / 1000 - For 720 hours: (50 watts × 720 hours) / 1000 = 36 kWh
For 240 hours: (50 watts × 240 hours) / 1000 = 12 kWh
Multiply your kWh usage by your local electricity rate (let’s assume $0.12 per kWh):
- For 720 hours: 36 kWh × $0.12 = $4.32
- For 240 hours: 12 kWh × $0.12 = $1.44
This estimation illustrates how a UPS might affect your final electricity bill. Although the increase in costs appears manageable, considering the overall benefits of protection against power issues is essential while assessing value.
