How Much Does It Cost to Run a Sump Pump in New Jersey? (2026)
A sump pump draws 400 to 1,500 watts but only runs when the pit fills. In dry seasons that may be minutes a day; in a wet spring it can run for hours.
A typical sump pump (800 W) costs $0.20 per hour, or about $2.99 per month at 0.5 hours a day in New Jersey. Cheap to run

In New Jersey, with electricity at 24.9¢ per kWh (source: EIA Table 5.6.A, 2026-06), a typical sump pump costs $0.20 per hour and about $36.43 per year at 0.5 hours a day. That is about 36% more than the national average for the US ($2.20 per month), because electricity in New Jersey costs 24.9¢ per kWh against 18.3¢ nationally. Each $1.00 of electricity buys roughly 5.0 hours of use.
How to lower the cost of running a sump pump
- Fix grading and gutters so less water reaches the pit in the first place.
- Check the float switch. A stuck float can run the pump continuously.
- Size the pump correctly. An oversized pump short-cycles and wears out.
