Quick answer
A washing machine is usually a moderate running cost. The bigger household impact often comes from how often it runs, whether hot washes are common, and whether low spin speeds leave more water in clothes for the drying stage.
Running cost guide
Washing machine running cost
Most washing machines are not extreme electrical costs per cycle, but frequent laundry, high-temperature washes and poor spin choices can still add up. The running-cost question also links directly to what happens next if loads need long tumble-dryer sessions.

A lot of the electricity used by a washing machine goes into heating water, which is why cooler or eco-style programmes often reduce the cost.
A higher final spin may use a little more machine energy but reduce tumble-dryer time afterwards. That can still be the cheaper whole-laundry outcome.
A household doing several loads a week will see a much bigger yearly difference from programme choice than a household that washes infrequently.
What usually changes the answer
These are the practical details that usually change the answer more than a manufacturer headline or a one-line forum estimate.
- Water temperature matters more than most people expect because hot water needs energy.
- Load count matters more than machine wattage because modern machines spend a lot of time at low draw outside the heating stages.
- Low final spin speeds can make the dryer work harder afterwards, shifting cost from the washer to the dryer.
- Short hot washes can look efficient because they are quick, but they are not always the cheapest option.

How much does a washing machine cost per load?
Usually less than many people fear, especially on cooler eco-style programmes. The annual total depends much more on how often you wash.
Do hotter washes cost a lot more?
They can. Heating water is one of the main energy uses in washing, so moving from cooler everyday cycles to hotter ones can shift the total noticeably.
Can a higher spin speed save money overall?
Often yes, especially if you tumble dry afterwards. Less water left in clothes usually means less drying energy later.
