Reproducible workflow

Method, inputs, and worked result

Method

  1. 1Read billed kWh and period dates.
  2. 2Apply each rate component separately.
  3. 3Add fixed charges, applicable taxes, and credits.

Inputs used

  • 680 billed kWh
  • $0.16 per kWh energy rate
  • $14.50 fixed charge and 5% tax on energy

Worked example

One bill uses a flat energy rate, fixed service charge, and tax on energy only.

  1. 1.680 x $0.16 = $108.80.
  2. 2.$108.80 x 5% = $5.44.
  3. 3.$108.80 + $14.50 + $5.44 = $128.74.

Estimated bill: $128.74.

Reproduce: Replace kWh, rate, fixed charge, and tax rule with values printed on the bill.
