Dryer Running Cost Calculator
Estimate the cost per cycle, monthly cost, and annual electricity cost of running an electric clothes dryer from wattage and cycle duration or kWh per load.
Clothes Dryer Energy & Cycle Inputs
3.17 kWh per cycle (988.0 kWh/year)
Clothes Dryer Cost Per Cycle Formula
kWh Per Cycle = (Power Watts รท 1,000) ร (Cycle Minutes รท 60); Cost Per Cycle = kWh Per Cycle ร Rate ($/kWh)- Power & Duration Mode: Converts dryer heating wattage and drying minutes into kilowatt-hours (kWh) per load.
- Direct kWh Mode: Multiplies known kWh per cycle directly by your electricity rate.
- Annual Cost = Cost Per Cycle ร Loads Per Week ร 52.
Step-by-Step Worked Example
Calculation Steps:
- Energy Per Cycle = (3,800 รท 1,000) ร (50 รท 60) = 3.167 kWh per cycle
- Cost Per Cycle = 3.167 kWh ร $0.168 = $0.532 per load
- Annual Cost = $0.532 ร 6 loads/wk ร 52 weeks = $165.98/year
How to Use This Calculator
- 1Choose whether to enter Dryer Power (Watts) & Cycle Duration (Minutes) or Direct Energy Per Cycle (kWh).
- 2Input your electricity rate per kWh and the number of dryer loads you run per week.
- 3Review the cost per cycle, weekly, monthly, and annual operating cost breakdown.
Assumptions & Limitations
- In Power & Duration mode, enter average active heating wattage across the cycle (heating elements cycle via thermostat as clothes dry).
- Monthly cost is normalized as Annual Cost รท 12 (4.333 weeks/month).
Frequently Asked Questions
How many watts does an electric clothes dryer use?
Standard 240V residential electric dryers are rated between 3,000 and 5,400 Watts, averaging roughly 2.5 to 4.0 kWh of electricity over a 45-to-60-minute drying cycle.
How much less energy does a heat pump ventless dryer use?
Heat pump clothes dryers recycle warm air rather than venting it outdoors, typically consuming 1.0 to 1.5 kWh per loadโroughly 50% to 60% less electricity than conventional vented dryers.
Why does a clogged lint trap or vent duct increase dryer cost?
Restricted airflow traps moisture inside the drum, forcing the heating element and blower motor to run 15โ30 minutes longer per load.
