The selected consumption tariff and VAT were applied to monthly usage.
Consumption = Σ(watts × quantity × daily hours × 30) ÷ 1000, followed by tariff tiers and VAT.
This is a planning and comparison estimate. Final protection and conductor selection requires review by a licensed engineer or electrician, site-condition checks, manufacturer instructions, and the applicable code.
Calculation guide
Enter actual meter kWh or calculate it from equipment quantity, watts, operating hours, and days. The calculator then applies the selected tariff category, tiers, VAT, and entered additions.
This is an estimate rather than the utility billing engine. Reading-cycle length, adjustments, fees, current account status, and actual tariff treatment can change the final invoice.
Frequently asked questions
kWh = power in kW × operating hours × days, adjusted when the equipment does not run at full power continuously.
Reading periods, tariffs, fees, VAT, adjustments, and actual usage can differ. The calculator is for planning and comparison.
It depends on electrical input, compressor runtime, weather, insulation, and thermostat setting rather than switched-on hours alone.
Meter kWh is better for cost accuracy; an appliance schedule is better for identifying consumption sources.
