Laundry Load Cost Calculator
Multiply your weekly loads by the cost of one load — detergent, water and energy combined — to see the running total.
Formula
Weekly cost = loads per week x cost per load. Monthly = weekly x 4.33.
How it works
Cost per load covers detergent, water and electricity. Cold washes and full loads cut all three at once.
If you use a laundrette, the machine fee dominates the cost — at home, energy and detergent matter more.
FAQs
How do I find my cost per load?
Divide a detergent bottle's price by its stated loads, then add rough water and energy costs, or use your machine's energy rating.
Does washing cold really save money?
Yes — heating water is the biggest energy cost of a wash, so cold cycles are noticeably cheaper.
Why 4.33 weeks per month?
Because a year has 52 weeks, and 52 / 12 is about 4.33 — more accurate than assuming exactly 4 weeks.
