How Average Monthly Billing is calculated

  • Your Average Monthly Billing payment amount is based on the average dollar amount of your last 12 months' bills.​​​
  • Each month, the difference between the average amount that you are billed and the actual usage is placed into a deferred balance, either as a credit or debit.
  • One-twelfth of the deferred balance is applied to your ave​rage amount on each bill, and the sum is rounded to the nearest dollar to determine your total Average Monthly Billing amount.

Things to know​

If you close your account or if service is turned off for non-payment or if your account becomes two months past due, your Average Monthly Billing plan will be discontinued.


If you de-enroll or if you are removed from the program, we will review your account and send you a bill with the difference between what you have paid on the Average Monthly Billing plan and the amount of natural gas you have used.

  • If you have paid more for natural gas than you have used, we will issue you a credit.
  • If you have an outstanding deferred balance, a deferred payment agreement may be available to qualifying customers.

Your Average Monthly Billing Amount is only for your natural gas cost. It does not include charges for additional services you may have contracted for with HomeServe. You are responsible for submitting a single payment that includes both CenterPoint Energy natural gas charges and HomeServe charges.
