About this tool
Per-wash electricity, water and detergent cost for front-load, top-load and semi-automatic machines, plus the monthly and yearly bill.
This calculator works out the true cost of one wash cycle by splitting it into the three things you actually pay for: the electricity the drum and heater consume, the water the machine draws, and the detergent you pour in. The energy side uses the standard heat equation — litres × 4.186 kJ per kg per °C × temperature rise ÷ 3600 — added to the mechanical energy of the drum, pump and spin, which is why raising the programme from cold to 60 °C multiplies the bill several times over. It is aimed at anyone deciding between a front loader and a top loader, or wondering whether the warm-wash habit is worth what it adds to the monthly bill.

The breakdown splits drum energy from water heating, so you can see exactly what the temperature dial costs.
Top loaders use roughly twice the water of front loaders, and that difference shows up in rupees per year.
Electricity per unit, water per kilolitre and detergent per wash are all editable, so the answer matches your bill and not a national average.
A cold wash in a 7 kg front loader uses roughly 0.3 kWh, while the same load at 60 °C uses about 1.3 kWh — over four times more, because heating the wash water dominates the cycle. Semi-automatic machines use the least electricity of all, around 0.2 kWh, since they run short cycles with no heater.
Yes. A typical 7 kg front loader draws about 55-60 litres a cycle against 105-120 litres for a fully automatic top loader of the same capacity, because tumble action reuses a shallow pool of water instead of floating the clothes. Over 260 washes a year that is roughly 15 kilolitres of water saved.
For most household laundry, yes — switching from a 40 °C to a cold programme cuts about 0.4 kWh per wash, which at ₹8 a unit and five washes a week works out to roughly ₹800 a year. Keep hot washes for genuinely soiled items, bedding and nappies, where the temperature does hygienic work.
Slightly less on a load-sensing front loader, and almost nothing on a top loader or semi-automatic, where you set the water level yourself and the motor runs the same programme regardless. Filling the drum to about three-quarters gives the lowest cost per kilogram of laundry — the figures here assume a full rated load.
