How Often Should You Replace an HVAC Filter?

Quick answer: A clothes dryer��s electricity cost depends on the dryer, cycle, load, and local utility rate. As an example, a dryer that uses 4 kWh per load costs about $0.69 per load at the 2025 U.S. residential average rate of 17.30 cents per kWh.

This is an example calculation, not a universal average. Check your utility bill and the appliance information for a more precise estimate.

How to calculate the cost

Electricity cost = kWh used �� electricity rate

At 4 kWh and $0.173 per kWh: 4 �� $0.173 = $0.692, or about $0.69 per load. Twelve loads per month would cost about $8.28 at the same rate.

What changes dryer electricity use?

  • Load size and fabric type
  • Cycle length and heat setting
  • How much water the washer removes
  • Dryer age and efficiency
  • Lint buildup or restricted vent airflow
  • Your local electricity rate

Ways to reduce the cost

  1. Use a high-spin washer cycle.
  2. Avoid overloading the drum.
  3. Use sensor-dry or lower-heat settings when appropriate.
  4. Clean the lint filter after every load.
  5. Inspect the vent if drying suddenly takes longer.

ENERGY STAR uses Combined Energy Factor (CEF) to compare dryer efficiency. Its guidance also highlights moisture sensors, lower-energy cycles, and regular lint-filter cleaning.

Why your local rate matters

The U.S. Energy Information Administration reported a 2025 average residential electricity price of 17.30 cents per kWh, but rates vary widely by state and utility provider. Replace $0.173 in the example with the rate on your bill.

When to call a professional

Stop using the dryer and contact a qualified appliance or dryer-vent professional if it overheats, smells like burning, has poor airflow, leaves clothes damp after normal cycles, or repeatedly trips a breaker.

Bottom line

The most reliable estimate comes from your dryer��s actual kWh use and local electricity rate. The 4 kWh example is about $0.69 per load at the cited U.S. average rate.
