After our electric bill jumped one summer, I started looking at where we were wasting money. Laundry was a bigger drain than I realized. Between expensive detergent, hot water washes, the dryer running constantly, and clothes wearing out fast, we were spending $80 a month just doing laundry.

I changed 12 small things over 3 months and cut that to under $40. Same amount of laundry, half the cost. Here is exactly what I changed and how much each one saved.

Why Laundry Costs Add Up Fast

Most people underestimate laundry costs because they are spread across multiple bills. According to the US Department of Energy, laundry accounts for about 5% of average home energy use. Add detergent, accessories, and worn-out clothes from bad practices, and a family of 4 easily spends $1,000+ per year on laundry.

The good news: every change on this list saves real money you can measure within one month.

What Is the Cheapest Way to Do Laundry?

The cheapest way to do laundry is to wash in cold water, use the smallest amount of detergent that works, air dry whenever possible, and run only full loads. These four habits alone save an average family $30 to $50 per month with zero upfront cost.

12 Ways to Save Money on Laundry

1. Wash in Cold Water (Saves $60 to $150 per Year)

According to the Department of Energy, 90% of washing machine energy goes to heating water. Switching to cold for most loads cuts that cost completely.

Cold water works fine for:

  • Everyday clothes
  • Lightly soiled items
  • Colors and darks
  • Delicates

Use warm or hot only for:

  • Heavily soiled clothes
  • Whites you want to brighten
  • Towels and sheets every few washes for sanitizing

2. Use Less Detergent (Saves $50 to $100 per Year)

The detergent industry has trained us to fill the cap. You typically only need 1/3 to 1/2 of that amount. Extra detergent does not clean better. It leaves residue, attracts dirt, and makes machines work harder.

Test: Use half your normal amount for a month. Clothes will be just as clean. You will use half the detergent, doubling its shelf life.

3. Buy Concentrated Detergent (Saves $30 per Year)

Concentrated formulas cost slightly more per bottle but deliver 2 to 3 times more loads. The cost per load is 30 to 40% less. Read the label for “concentrated” or “ultra” versions.

4. Switch to Wool Dryer Balls (Saves $60+ per Year)

Wool dryer balls cost $15 to $20 once and last 1,000+ loads. They:

  • Reduce drying time 15 to 25%
  • Replace dryer sheets entirely
  • Prevent static
  • Soften clothes naturally

The math: $5 per month for dryer sheets + 20% lower dryer energy = $60+ saved per year.

5. Air Dry When Possible (Saves $40 to $100 per Year)

The dryer is the second most expensive appliance to run after the oven. Air drying even part of your laundry adds up.

Easy air dry items:

  • T-shirts
  • Pajamas
  • Athletic wear
  • Sheets and towels in summer
  • Delicates

A folding wooden drying rack costs $25 and pays for itself in 3 months.

6. Run Only Full Loads (Saves $30 per Year)

Half-full loads use almost the same water and energy as full loads. Calculate: each load uses 15 to 40 gallons of water plus heating energy. Two half-loads cost almost twice as much as one full load.

If you wash daily, wait an extra day to accumulate a full load. Use the small load setting only when necessary.

7. Use the High Spin Cycle (Saves $20 per Year)

A high-spin cycle removes more water from clothes, meaning the dryer works less. The 2-minute increase on the wash time saves 5+ minutes of dryer time. Net result: less total energy.

8. Clean the Lint Filter Every Load (Saves $30 per Year)

A clogged lint filter forces the dryer to work harder, costing more in electricity and risking fire. The US Fire Administration reports 2,900 home dryer fires per year, most from lint buildup.

Bonus: clean the dryer vent (the long hose) once a year for additional efficiency.

9. Make DIY Stain Treatment ($0 vs. $15 per Year)

A spray bottle of equal parts white vinegar, water, and a teaspoon of dish soap removes most stains as well as commercial pre-treaters at a fraction of the cost.

For tougher stains, our stain removal guide has recipes for every type.

10. Wash Less Often (Saves $50 per Year)

Many items do not need washing after every wear:

  • Jeans: every 4 to 5 wears
  • Pajamas: every 3 to 4 wears
  • Sweaters: every 5 to 6 wears (unless visibly dirty)
  • Bras: every 3 to 4 wears
  • Towels: every 3 uses

This reduces water, energy, detergent, and clothing wear all at once.

11. Buy Quality, Wash Gently (Saves $200+ per Year)

Cheap clothes need replacing every 6 to 12 months because they wear out fast. A $30 quality t-shirt lasts 3 to 5 years. The math favors quality if you also wash gently.

Gentle washing means:

  • Cold water
  • Inside-out
  • In mesh bags for delicates
  • Air dry instead of hot dryer
  • Half the standard detergent

Our common laundry mistakes guide covers the practices that destroy clothes fastest.

12. Off-Peak Energy Times (Saves $30 per Year)

Some utility companies charge less for electricity at off-peak hours (usually evenings and weekends). Check your utility’s rate plan. If you have time-of-use pricing, running the washer and dryer during cheap hours can save 20% on those loads.

What I Wish I Knew

Lessons from a year of cutting laundry costs.

The detergent test changed everything. I doubted that half the recommended amount worked. I tested it for a month, comparing clothes before and after. No difference. I went back to my old amount briefly and switched back to half because the difference in detergent residue was visible on dark clothes.

Wool dryer balls actually work. I was skeptical of “natural alternative” products. These are the rare exception. They genuinely reduce drying time, soften clothes, and last forever.

Air drying changed my fall routine. I started air drying in summer for the energy savings. Then I realized clothes lasted longer. Now I air dry most things year-round.

Track laundry expenses for a month. I had no idea how much I was spending until I added it up. Detergent, dryer sheets, energy. The reality check motivated the changes.

Most “value” deals are not. Big box stores’ giant detergent bottles look cheap but the cost-per-load is sometimes higher than concentrated versions. Read the labels.

How Can I Save Money on Detergent?

Save money on detergent by using half the recommended amount (still cleans effectively), buying concentrated formulas (more loads per bottle), watching for sales and stocking up, using DIY stain treatments instead of commercial pre-treaters, and avoiding scented detergents that cost 20 to 40% more than unscented versions.

Monthly Savings Calculation

If you do all 12 tips, here is the math:

  • Cold water washing: $10/month
  • Less detergent: $5/month
  • Concentrated detergent: $3/month
  • Dryer balls: $5/month
  • Air drying: $5/month
  • Full loads only: $3/month
  • High spin cycle: $2/month
  • Lint filter cleaning: $3/month
  • DIY stain treatment: $1/month
  • Wash less often: $4/month
  • Quality clothes (longer term): $17/month
  • Off-peak energy: $3/month

Total monthly savings: $61 Annual savings: $732

Tools to Track Laundry Costs

Keep a simple spreadsheet or notebook:

  • Detergent purchases and dates
  • Approximate loads per month
  • Utility bill before and after changes
  • Replacement clothes purchased

You will see the savings within 2 to 3 months of consistent changes.

Key Takeaway

Laundry costs add up faster than people realize, but small consistent changes deliver big savings. The biggest wins are cold water washing, less detergent, wool dryer balls, and air drying when possible. Combined, these four changes alone save the average family $30 to $50 per month. Start with cold water this weekend. It costs nothing to change and you will see savings on your first electric bill. The other changes build up from there.
