What is Cost Per Load?
Cost per load measures how much each individual load costs when you divide the total expense by the number of loads. While commonly used for laundry, this metric applies to any batch-based cost calculation, from dishwasher cycles to trucking shipments.
How to Calculate Cost Per Load
The formula is straightforward:
[\text{Cost Per Load} = \frac{\text{Total Cost}}{\text{Number of Loads}}]
Where:
- Total Cost is the total expense in dollars (detergent, utilities, supplies, or any combined cost)
- Number of Loads is the total count of loads
Calculation Example
You spend $75 on laundry supplies that last for 15 loads:
[\text{Cost Per Load} = \frac{75}{15} = 5.00]
The cost per load is $5.00.
Another Example
A bottle of concentrated detergent costs $12 and is rated for 40 loads:
[\text{Cost Per Load} = \frac{12}{40} = 0.30]
The detergent cost per load is $0.30.
Comparison Table
| Product | Total Cost | Loads | Cost Per Load |
|---|---|---|---|
| Budget Detergent | $6.00 | 20 | $0.30 |
| Premium Detergent | $18.00 | 40 | $0.45 |
| Laundromat (per visit) | $4.50 | 1 | $4.50 |
| Home Wash (all-in) | $75.00 | 15 | $5.00 |
Tips for Reducing Cost Per Load
- Wash full loads: Running partial loads wastes water and energy without reducing the fixed costs per cycle.
- Use cold water: Heating water accounts for roughly 90 percent of the energy used in a wash cycle. Cold water works well for most everyday laundry.
- Choose concentrated detergents: They often deliver more loads per dollar than standard formulas.
- Air dry when possible: Skipping the dryer eliminates its energy cost entirely and extends the life of your clothing.
- Maintain your machines: Clean lint traps, descale regularly, and keep seals in good condition to maintain efficiency and avoid costly repairs.
