What every dryer cycle actually costs.

Calculate tumble dryer cost per cycle and annual cost. Enter power, time, rate, and usage. Enter dryer power kw to see cost of running a tumble dryer.

What this tool does

This tool calculates the cost of running a tumble dryer. Enter dryer power in kW, cycle duration in hours, electricity rate per kWh, and cycles per week. The calculator shows cost per cycle, weekly cost, annual cost, and power usage per cycle.

Tumble dryers are among the most power-hungry household appliances, consuming 2-4 kWh per cycle. At current electricity rates, each cycle costs 60p-1.20. Running one 5+ times weekly adds 150-300 to annual electricity bills. This calculator shows exact cost based on your dryer and rate.

A 2.5 kW dryer running 1.5 hours per cycle at 0.28/kWh costs 1.05 per cycle, 5.25 weekly at 5 cycles, and 273 annually. Air-drying even half the loads saves 137 annually and extends clothing life.

The tool is useful for decision-making: is a heat-pump dryer (lower kWh) worth the 400-800 premium? Typically yes if you dry frequently - payback often comes within 3-5 years on running-cost savings alone. Air drying always wins financially but requires time and space not everyone has.

Quick example

With dryer power of 2.5 and cycle duration of 1.5 (plus electricity rate per kwh of 0.28 and cycles per week of 5), the result is 1.05. Change any figure and watch the output shift — it's often more useful to see the pattern than to memorise the formula.

Which inputs matter most

You enter Dryer Power (kW), Cycle Duration, Electricity Rate per kWh, and Cycles per Week. Frequency and unit price pull the total in different directions. The biggest surprise for most people is how small recurring amounts compound into large annual figures — that's where this calculation earns its keep.

What's happening under the hood

Cost per cycle = power × hours × rate. Weekly = cycle cost × cycles. Annual = weekly × 52. The formula is listed in full below. If the number looks off, you can retrace the calculation by hand — that's the point of showing the working.

Why a budget needs to be specific

Budgets fail when they're built from ideals instead of actuals. Track what you actually spend for a month before fixing the plan — categories like "eating out" and "subscriptions" are reliably 30–50% higher than people's first estimate.

What this doesn't capture

Budgets are snapshots of intent. Real spending includes irregular costs: birthdays, one-off repairs, the occasional bad week. Tracking actual spending for a month before fixing any budget usually reveals 10–20% that didn't make the original plan.

Example Scenario

2.5kW × 1.5 hoursh × £0.28 £/kWh = $1.05/cycle.

Inputs

Dryer Power (kW):2.5
Cycle Duration:1.5 hours
Electricity Rate per kWh:0.28 £
Cycles per Week:5
Expected Result$1.05

This example uses typical values for illustration. Adjust the inputs above to match a specific situation and see how the result changes.

Sources & Methodology

Methodology

Cost per cycle = power × hours × rate. Weekly = cycle cost × cycles. Annual = weekly × 52.

Frequently Asked Questions

Is a heat-pump dryer cheaper?
Yes - typically 50-70% less energy per cycle than conventional. A 2.5 kWh conventional vs 1 kWh heat-pump running 5x/week saves 110-200/year. Heat-pump dryers cost 400-800 more upfront but often pay back in 3-5 years for regular users.
How much cheaper is air drying?
Completely free in terms of electricity. Also gentler on fabrics, extending clothing life by 30-50% on cottons and delicates. Main trade-offs: time, space, and humidity management indoors in winter.
Do dryers use the full rated power throughout cycle?
No. Conventional dryers draw peak power for heating, then reduce once warm. Average actual consumption is typically 70-80% of rated power × hours. The calculation slightly overestimates but is close enough for planning. Check actual kWh via smart meter if precision matters.
Peak vs off-peak rates?
If on Economy 7 or similar tariffs, running dryer at night cuts rate from 28p to 14p per kWh - halving cost. A timer plug or smart socket makes this automatic. For dryer-heavy households this saves 50-100/year.
