About pond pump running costs
Pond pumps often run for long periods, so even modest wattage can add up over a month. Actual power depends on flow and lift height.
Typical sizes: 50 W, 100 W, 150 W, 250 W.
How to spend less: Use a pump sized to the pond and clean the intake regularly.
What this estimate assumes
- The appliance draws its full stated wattage the whole time it is on. Real units with a thermostat cycle off and cost less.
- Wattage is the typical label value, not a measured value. Check the label on your own appliance.
- The rate is an approximate residential average in Oklahoma. Your bill may include fixed fees, tiers or time-of-use pricing. Edit the rate above.
- A month is 30 days and a year is 365 days.
