With the solar output of Phoenix (PVWatts), a 6 kW system makes about 10,529 kWh a year. On a home that uses 1,000 kWh a month, it cuts the yearly bill by:
| Plan | Bill a year without solar | Savings a year |
|---|---|---|
| TOU-ETime-of-Use 4pm-7pm Weekdays | $2,301.30 | $1,852.80 |
| R-1Fixed Energy Charge Plan | $2,205.36 | $1,763.05 |

A bill that crosses a season or rate change: the calculator uses the season of the billing month and does not split it. The tariff uses the May to October and November to April billing cycles.
These examples use 1,000 kWh and 30 days. Each column uses the rates of the billing month in its heading. In seasons with time periods, the examples use this split: 15% on-peak and 15% super off-peak, and the rest off-peak. This split is only an example. Use the values from your bill. The examples do not include taxes.

Values read from the text of APS Rate Schedule TOU-E and the adjustment schedules that it lists (PSA-1, TCA-1, REAC-1, DSMAC-1, LFCR, TEAM, CRS-1 and SRB-1), as linked from the APS Rates, Schedules and Adjustors page. TEAM and SRB-1 are $0.000000 per kWh and are not shown. The LFCR uses the energy-only rate. We did not find an official statement of which APS plan is the default for new customers, so this page does not say that TOU-E is the default. An APS rate case is pending at the Arizona Corporation Commission; news reports say that new rates can start in early 2027. APS does not publish a typical bill with a line breakdown, so the test bills are hand calculations. APS rates, schedules and adjustors.

The most common reason is more kWh: heating and air conditioning use much electricity. The season: on Schedule TOU-E, 1,000 kWh costs $199.78 in October and $183.77 in November. The time of use: kWh in the peak hours cost more than kWh at other hours. More days in the billing period also add kWh and daily charges. To see which reason applies to your bill, use the Why is my bill so high tool on this site: type your bill and an earlier bill, and it shows each reason in dollars.
Your bill can include sales tax, a city fee, a discount, a late fee or a different number of days. Type the number of days from your bill. To add tax, type the tax rate from your bill in the tax field. If your tariff has a discount program, select it in the options.
Your bill shows the kWh for the billing period. Look for the meter reading section or the usage section.
