Why this matches your actual bill.
Three numbers, one answer
Your usage, the plan rate, and your TDU territory. We do the math the way your bill does — energy charge plus delivery plus taxes — instead of just multiplying rate by kWh.
Real Texas defaults
TDU delivery defaults to $45/mo (Oncor and CenterPoint average). Most fixed plans don't add a separate base fee, so we default that to $10. Taxes default to 7% — the typical Texas blend of PUC fee, gross receipts, and local tax.
Plan picks at your tier
Below your estimate we surface three plans on the market that would beat your bill at your exact usage — ranked by true cost, not by the loudest advertised rate.
Heads up — this is an estimate. Your real bill depends on your TDU (Oncor, CenterPoint, AEP, TNMP), your plan's published EFL, and any bill-credit thresholds. Use the live compare view to see the exact dollar at your usage.
