You used less gas, or gas cost less. You used 161 therms this period against 255 in April.
Charges and taxes for the period; any previous balance is not part of the change.
Milder weather
This period had 38 heating degree days against 132 — 71% milder. At the same gas per degree of cold, that alone is about 101 therms less.
Natural gas cost
The purchased gas adjustment — what we pay for the gas itself, passed through at no markup — fell from $0.3655 to $0.3380 a therm.
Usage beyond the weather
Even allowing for the cold, you used about 7 therms more than your home usually does. Common causes: a higher thermostat, a new gas appliance, guests, or a leak. If you ever smell gas, leave and call (979) 555-0199 from outside.

Starting from the Apr 2025 bill, the engine re-prices it at the volume the weather predicts, then at the volume used, then swaps in this period’s gas cost, weather adjustment, and each base rate in turn. Every step is priced line by line and rounded the way the biller writes lines, so the steps add to the real difference — −$48.84 — to the cent. It reproduces every issued bill in the system exactly.
