Air conditioner electricity cost in Brazil

Cooling cost varies with climate, voltage, inverter loading, distributor tariff, taxes, monthly tariff flags, and long hot-season schedules.

Rate used for the starting scenarioBRL 0.7894/kWh

Use the marginal R$/kWh for your distributor and add the current tariff-flag component only when it is not already included.

Billing scopeSão Paulo · Enel SP

Confidence A 99/100. Effective 2026-07-04 to 2027-07-03.

Live local scenario

Calculate with an editable rate.

Air conditioners cycle or modulate, so scheduled hours alone overstate energy use. The active-runtime input represents average compressor load across the operating window.

Your scenario

Change any value. Results update instantly.

Active runtime accounts for cycling. Use 100% for devices that draw the rated power continuously.

Worked calculation

A Brazil starting scenario

1.500 kW is multiplied by scheduled time and the 55% active-runtime assumption. The inputs are examples, not claims about every device. Replace each one with the label, meter reading, schedule, and tariff that apply to you.

AC cost = rated kW × scheduled hours × active-runtime share × tariff

Transparent method

The local calculation

AC cost = rated kW × scheduled hours × active-runtime share × tariff

The device model stays global. The currency, tariff scope, validity period, and billing cautions come from the Brazil data layer.

Before trusting the result

Three checks for Brazil

01

Confirm whether the unit is rated for 127 V or 220 V supply.

02

Use compressor duty rather than scheduled hours alone.

03

Treat the Enel São Paulo B1 value as regional and tax-exclusive.
