Calculation path

The calculator keeps consumption-based charges separate from fixed and other charges, then applies your entered tax percentage to the subtotal. It also shows daily use and the all-in average billed rate.

Calculation path

Energy charge = energy used x flat rate. Subtotal = energy charge + fixed charge + other charge. Total = subtotal + entered tax or duty.

What you provide

What you provide

  • Energy consumption for one billing period
  • A tariff or blended rate you have checked
  • Fixed charge, other positive charges, tax percentage, and billing days

What you receive

What you receive

  • Estimated bill total
  • Usage, fixed-charge, other-charge, and tax breakdown
  • Average daily use and all-in cost per energy unit

Use boundary

Choose the maximum decimal places shown. This does not increase source accuracy.

Use your supplier tariff for an accurate rate. This generic estimator does not infer a country, provider, customer class, or billing rule.

Credits and rebates are not accepted as negative inputs; subtract them from the final estimate separately and label the adjustment.
