The real cost of doing laundry
Most people know they spend money on laundry detergent. Far fewer think about the energy, water, and machine wear that make up the rest of the bill. When you add it all together, laundry is one of the more significant utility costs in a typical home — and also one of the most reducible.
This breakdown uses US average household data (8 loads/week, $0.16/kWh electricity, $0.004/gallon water) and 2026 retail prices. Adjust for your own inputs to get your personal figure.
Component 1: Detergent cost per year
At 8 loads per week, you run approximately 416 wash cycles per year. Detergent cost varies enormously by format:
- Eco powder (e.g., Ecover, Bio-D): $0.10–0.18/wash → $42–75/year
- Eco liquid concentrate: $0.12–0.20/wash → $50–83/year
- Laundry strips (e.g., Tru Earth, Earth Breeze): $0.22–0.32/wash → $92–133/year
- Eco pods: $0.22–0.35/wash → $92–146/year
- Conventional Tide pods (comparison): $0.28–0.40/wash → $116–166/year
Eco powder is consistently the cheapest option per wash. See our full laundry format comparison for a deeper look at the eco trade-offs beyond cost.
Component 2: Washing machine energy per year
A standard washing machine uses 0.5–1.5 kWh per cycle depending on temperature and efficiency rating. Energy Star certified models use 0.3–0.7 kWh at cold/warm settings.
- Washing at 60°C (hot): ~1.5 kWh/cycle → 416 cycles × 1.5 × $0.16 = $100/year
- Washing at 40°C (warm): ~0.9 kWh/cycle → 416 × 0.9 × $0.16 = $60/year
- Washing at 20°C (cold): ~0.3 kWh/cycle → 416 × 0.3 × $0.16 = $20/year
Switching from warm to cold washing alone saves $40/year on a typical machine — and up to $80/year if you were using hot. Our cold water washing guide covers the cleaning performance data so you know what you're not sacrificing.
Component 3: Dryer energy per year
This is the biggest energy cost most people overlook. A standard electric dryer uses 3.5–5 kWh per cycle. Heat pump dryers use 1.5–2.5 kWh.
- Standard electric dryer (every load): 416 × 4 kWh × $0.16 = $267/year
- With wool dryer balls (10–15% faster drying): ~$227/year (saving ~$40)
- Air dry 50% of loads: ~$134/year
- Heat pump dryer: ~$112/year
The dryer is the laundry system's biggest energy cost. Our wool dryer balls vs dryer sheets test covers how much dryer balls actually speed up drying and whether the time savings are real.
Component 4: Water cost per year
Water costs are smaller but not zero, especially in regions with water rates above the US average.
- Standard top-loader (40 gallons/cycle): 416 × 40 × $0.004 = $67/year
- HE front-loader (15 gallons/cycle): 416 × 15 × $0.004 = $25/year
Total cost comparison: conventional vs eco
| Category | Conventional | Eco Optimised | Saving |
|---|---|---|---|
| Detergent (pods/liquid) | $140 | $60 | $80 |
| Washer energy (hot→cold) | $100 | $20 | $80 |
| Dryer (+ wool balls) | $267 | $200 | $67 |
| Water (HE machine) | $67 | $25 | $42 |
| Total | $574 | $305 | $269 |
Quick wins vs bigger investments
Free, immediate savings: Switch to cold water washing ($40–80/year saved), wash full loads only, stop using the dryer for small loads or easy-dry items.
Low investment ($15–30): Wool dryer balls (6-pack, lasts 1,000+ cycles) — save $40+/year on dryer time.
Higher investment: HE washing machine — saves $40/year on water and reduces detergent use. Heat pump dryer — saves ~$150/year vs standard electric dryer. Both pay back within 3–5 years.
The eco savings beyond cost
The optimised eco laundry setup above also eliminates approximately 40 plastic bottles per year (detergent), 300–400 single-use dryer sheets, and ~350 kg CO2 from energy savings. For the full picture of what those swaps involve, our eco detergent guide and eco laundry mistakes posts walk through the complete routine.
