Five cycles a week, 0.20 electricity per cycle, 0.10 water per cycle = 78/year in running costs. Over 10 years that is 780 — enough to influence buying decisions. Efficient A-rated models can halve the energy cost; the water cost depends on cycle type (30°C vs 60°C) and load size.

Run it with sensible defaults

Using cycles per week of 5, electricity per cycle of 0.2, water per cycle of 0.1, detergent per cycle of 0.15, the calculation works out to 117.00. Nudge the inputs toward your own situation and the output recalculates instantly. The defaults are meant as a starting point, not a recommendation.

The levers in this calculation

The inputs — Cycles per Week, Electricity per Cycle, Water per Cycle, and Detergent per Cycle — do not pull with equal force. 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.

How the math works

Weekly cycles × 52 × per-cycle total cost. Assumes consistent cycle cost and usage pattern. The working is transparent — you can verify every step yourself in the formula section below. No black box, no opaque "proprietary model".

Using the result to negotiate

The figure gives you a concrete number to quote when shopping alternatives. "I'm paying £X annually" cuts through marketing in a way "I want a better deal" doesn't. The specificity wins.

What this doesn't capture

Usage varies month-to-month; tariffs change; discounts come and go. The figure here is a clean baseline — your actual annual bill will fluctuate around it. Use the calculation to benchmark providers, not as a prediction of a specific bill.

Example Scenario

Washing machine cost produces an annual total based on the inputs provided.

Inputs

Cycles per Week:5
Electricity per Cycle:0.2 £
Water per Cycle:0.1 £
Detergent per Cycle:0.15 £
Expected Result£117.00

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

Methodology

Weekly cycles × 52 × per-cycle total cost. Assumes consistent cycle cost and usage pattern.

Frequently Asked Questions

How is per-cycle electricity calculated?
kWh per cycle (from energy label) × your electricity rate. A 1 kWh cycle at 0.30/kWh is 0.30 per cycle.
Does wash temperature matter?
Yes, a lot. 60°C uses 2-3× the electricity of 30°C. Modern detergents clean at 30°C effectively for most loads.
Cold water line instead of hot?
Most washing machines heat water internally. A cold fill saves nothing directly since the machine heats anyway. The energy label covers the standard cycle.
Drying cost not included — why?
Tumble drying is a separate appliance and often costs more than washing. Line drying or condensing dryers have very different cost profiles.
