Electricity-cost calculators for Australia

Use Australian dollars, 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.

Plans can use single, controlled-load, or time-of-use rates, and availability differs by network area and postcode. Daily supply charges are separate from usage rates.

Residential DMO single/flat rate, New South Wales · Ausgrid. Effective 2026-07-01 to 2027-06-30. Your own marginal bill rate remains the better input when your plan differs.

WhoPowerCost Lab's research desk maintains the formulas, market notes, and worked examples.

WhyThe page exists to answer an operating-cost decision. Advertising never changes a formula, default, or recommendation.
