Notes & Disclaimer

Not included in estimates: certain minor per-kWh surcharges, taxes, and regulatory fees.

Net metering: Solar excess credits are calculated per TOU bucket per billing cycle using the selected NMR-405 tranche rate. Default is Tier 4 (75%), which applies to new installations. If your install is grandfathered at a higher tier, select it above. You can also set your actual billing cycle start day — by default we assume the 1st of the month, which is usually close enough.

These are estimates. We do our best to keep rates accurate and up to date, and I use this tool myself for my own bills. That said, rates change, edge cases exist (grandfathered plans, business accounts, uncommon tariffs), and bugs are always possible. If something looks off, please let us know so we can fix it.

Use at your own risk.
