How to Use This Laundry Load Calculator
This calculator helps you plan your laundry efficiently by calculating the number of loads needed, total costs, and detergent amounts.
By Weight Method
- Enter your total laundry weight in pounds
- Enter your washing machine's capacity (usually 8-18 lbs for home machines)
- Enter the cost per load (water, electricity, and machine use)
- Enter how much detergent you use per load
- Click "Calculate Laundry Loads" to see your results
By Items Method
- Count how many of each clothing item you need to wash
- Enter the quantities in each field
- Enter your machine capacity and costs
- The calculator uses average weights for each item type
- Get an accurate estimate of loads needed
Example: If you have 25 lbs of laundry and a 12 lb capacity machine, you'll need 3 loads (2 full loads at 12 lbs each, plus 1 partial load with the remaining 1 lb). At $1.50 per load, your total cost would be $4.50, and you'd need 6 oz of detergent.

- Jeans: 1.5 lbs
- Towel: 1.2 lbs
- Bed Sheet: 1.5 lbs
- Underwear: 0.15 lbs
- Socks (pair): 0.1 lbs
- Hoodie: 1.0 lb

Understanding Machine Capacity
Washing machine capacity is measured in pounds or cubic feet. Here are typical capacities:
- Compact machines: 6-8 lbs (perfect for apartments)
- Standard top-loaders: 10-12 lbs (most common home washers)
- Large top-loaders: 15-18 lbs (family-sized)
- Front-loaders: 12-16 lbs (efficient and gentle)
- Commercial machines: 20-40 lbs (laundromats)
Important: Don't overload your machine. Fill it about 3/4 full for best cleaning results and to prevent damage.
Frequently Asked Questions
How do I know my washing machine's capacity?
Check your machine's manual or the label inside the door. If you can't find it, a standard top-loader is usually 10-12 lbs, and a front-loader is typically 12-16 lbs. You can also weigh a basket of laundry to estimate.
Should I fill the machine completely?
No. Fill the machine about 3/4 full to allow clothes to move freely. Overloading prevents proper cleaning and can damage your machine over time.
How much does a load of laundry actually cost?
Home washing typically costs $0.75-$2.00 per load including water, electricity, and detergent. Laundromats usually charge $1.50-$5.00 per load depending on machine size and location. Dryers add $0.25-$1.00 per cycle.
How often should I do laundry?
Most households do 2-5 loads per week. This depends on family size, activity level, and personal preferences. Doing full loads less frequently is more efficient than small loads often.
Can I wash different fabric types together?
Generally, it's best to separate delicates from regular clothes and heavy items like towels from lighter garments. Mixing fabrics can cause damage, shrinking, or poor cleaning results.
How much detergent should I really use?
Most people use too much detergent. For standard machines, 1-2 tablespoons (0.5-1 oz) is usually enough. High-efficiency (HE) machines need even less—about 1-2 teaspoons. Check your detergent's label for specific guidance.
Does the "By Items" method give accurate results?
Yes, it provides good estimates using average item weights. Actual weights may vary by size and fabric, but the calculator gives you a reliable planning tool for typical clothing items.
How do I estimate laundry weight without a scale?
Use the "By Items" method in this calculator. Count your clothing pieces and let the tool estimate the weight. Alternatively, a full laundry basket typically holds 15-20 lbs of clothing.
