What this calculator tells you
See what a pump costs to run per year, and what a worn pump is quietly adding to your bill. Need your total dynamic head? Get it from our Pump Sizing Calculator.
Results
Power draw: 0 kW
Annual energy cost:
$0 per year
10-year energy cost: $0
Restoring a worn pump from 65% to 75% efficiency would save about $0 per year.
A worn impeller or the wrong operating point can quietly cost thousands per year. A pump health check catches it.
How this is calculated
- kW = GPM x TDH x specific gravity x 0.746 / (3,960 x pump efficiency x motor efficiency).
- Annual cost = kW x operating hours x electric rate ($/kWh). The 10-year figure uses today's rate with no escalation.
- The improvement line reruns the same formula with pump efficiency 10 points higher (capped at 90%) and shows the difference.

Common questions
How much does it cost to run a pump per year?
Electrical power in kW = GPM x total dynamic head x specific gravity x 0.746 / (3,960 x pump efficiency x motor efficiency). Multiply by operating hours and your electric rate. A pump moving 200 GPM against 80 feet of head at 65 percent pump efficiency and 92 percent motor efficiency draws about 5 kW, which is roughly 2,500 dollars per year at two-shift operation and 12 cents per kWh.
How much energy does a worn pump waste?
Wear ring clearance, impeller erosion, and running away from the best efficiency point commonly cost 10 or more points of efficiency. Dropping from 75 to 65 percent efficiency on a continuously running pump raises the power draw by about 15 percent, often thousands of dollars per year on larger pumps. Restoring the pump to spec recovers that money every operating hour.
What is a pump health check?
A pump health check measures flow, head, power draw, and vibration to establish where the pump is operating on its curve and how far its efficiency has drifted from spec. It identifies worn impellers, wrong operating points, and throttled valves, and puts a dollar figure on fixing each one before deciding on repair or replacement.
