Cost to run a tumble dryer: per load, per month, per year
In one line: At roughly 3,000 W, a dryer hour costs around 55 cents or 55p. The per-load maths, the heat-pump exception, and the rack combo that costs pennies.
The tumble dryer is usually the most expensive plug-in appliance in the home, and it earns the title honestly: about 3,000 watts for an hour-plus per load. At an average US rate near 18-19 cents per kWh (about 26p on the UK cap rate), one load costs roughly 55-65 cents or 55-60p in electricity - and a household doing a load a day spends in the region of 16-20 dollars or pounds a month, every month. Run your dryer's cycle time and your own rate through the electricity cost calculator for the precise figure.
The dryer ladder
Vented (cheapest to buy, dearest to run): a 3 kW element dumping warm damp air outside. Condenser: similar power, slightly less efficient. Heat-pump dryer (the modern answer): it recycles its own heat, using roughly half to a third of the power per load - and since dryers are replaced rarely, the running-cost saving usually repays the higher price over the machine's life, the same long-arithmetic as repair-or-replace. Check the energy label's kWh per cycle rather than trusting a category.
Cutting the cost without buying anything
Spin harder first: an extra spin cycle removes water for pennies and shortens dryer time substantially. Dry full (but not overloaded) loads back-to-back so the drum stays warm. Clean the lint filter every load and the vent annually - a choked vent adds time and is also the fire-risk subject of proper dryer maintenance. And in any month where the bills shout, the rack-and-dehumidifier combo dries a load for pennies: the dehumidifier maths shows the contrast. Line-drying in season stays free - the indoor-drying guide covers the damp-weather version.
The honest comparison
The dryer is a convenience appliance, and there is no shame in convenience - but price it honestly: it is often the single largest electricity line after heating, cooling and water heating, right up there with the air-conditioning maths. Knowing the per-load figure turns "just one more cycle" into a decision instead of a habit.
