Electricity-cost calculators for Brazil

Use Brazilian reais, your own tariff, and device-specific operating models—without pretending one national average fits every household.

Billing context

Use the rate that changes with consumption.

Residential tariffs differ by distribution utility and can include energy and network components, taxes, public-lighting charges, and monthly tariff flags. A single Brazil-wide household rate would be misleading.

B1 conventional residential, São Paulo · Enel SP. Effective 2026-07-04 to 2027-07-03. Your own marginal bill rate remains the better input when your plan differs.
