Running Cost & Savings Calculator

See what your equipment really costs to run each month and year - on your own electricity rate. Compare up to three, side by side.

1 · Add your equipment

Search the catalogue for each slot. Rated power fills in automatically where available.

2 · Your usage & rate

Applies to all items.

How long it's switched on.
Most F&B: 350-365.
Default: Tariff B (RP4).

3 · What each costs to run

Rated power and daily energy use are editable. Cheapest to run is highlighted.

ℹ️ We automatically account for how each appliance draws power - a fridge compressor cycles on and off, so it isn't billed as if it ran flat-out 24/7. You don't need to set anything.

How we calculate this

Annual running cost = (rated power in watts / 1000) x usage factor x hours/day x days/year x electricity rate. Monthly = annual / 12.

The usage factor accounts for duty cycling - e.g. a fridge compressor does not run at full draw continuously. Electricity rate default: RM 0.435/kWh, Tariff B small commercial (TNB RP4). Verify the current rate at mytnb.com.my/tariff.

Where the manufacturer gives daily energy use (kWh per 24 hours), annual running cost = kWh per day x days/year x electricity rate. That figure already reflects compressor cycling, so no usage factor or hours are applied.
