Laundry Load Calculator

Load Estimation

The calculator estimates weekly laundry loads using industry averages:

1. Per-person laundry output: Adults generate roughly 2 loads per week; children generate about 1.5 loads. These are adjusted by activity level.
2. Bed linens & towels: Adds approximately 1 load per week for every 2 household members (washed weekly).
3. Activity multiplier: Low = 0.8×, Moderate = 1.0×, High = 1.3× of the base load count.

Cost Calculation

1. Water cost per load: gallons per load ÷ 1,000 × water rate
2. Energy cost per load: kWh per load × electricity rate (plus dryer if included)
3. Total cost per load: water + energy + detergent
4. Weekly/monthly/yearly costs: cost per load × number of loads in the period

Typical Water Usage by Washer Type

• HE Front-Load: 13–15 gallons per load
• HE Top-Load: 15–20 gallons per load
• Standard Top-Load: 30–45 gallons per load

Tips to Reduce Laundry Costs

• Wash full loads instead of partial loads to maximize efficiency
• Use cold water for most loads — heating water accounts for about 90% of washer energy use
• Clean the dryer lint filter before every load to improve efficiency
• Consider air-drying clothes when weather permits
• Upgrade to an HE front-load washer for the lowest water and energy consumption
