Gas Bill High but Usage Is the Same? What to Check

If your gas bill increased even though your gas usage stayed about the same, the extra cost may be coming from the pricing or account side of the bill rather than additional consumption. Compare the gas supply or commodity rate, delivery charges, fixed customer charges, billing days, riders or adjustments, taxes, credits and any previous balance.

First, Make Sure Usage Really Is the Same

Before looking at rates, compare the consumption shown on both bills.

Use the same measurement unit on each bill. Depending on the utility, you may see therms, CCF, Mcf or another billing presentation.

That does not prove a billing problem. It tells you to examine rates and other charges more closely.

1. Did the Gas Supply or Commodity Rate Increase?

A higher commodity rate can increase your bill even if you consumed nearly the same amount of natural gas.

For example:

These figures are fictional and are only meant to demonstrate how a rate change affects the bill.

2. Did Delivery or Distribution Charges Change?

Natural gas must be transported and delivered to customers.

EIA says the price paid by consumers has two broad components: the commodity cost and transmission and distribution costs. :contentReference[oaicite:1]{index=1}

Depending on your utility, the bill may use terms such as:

• Delivery charge
• Distribution charge
• Transportation charge
• Distribution service

The terminology and calculation method are utility-specific.

Compare these lines separately instead of looking only at the total amount due.

3. Did a Fixed Customer Charge Increase?

Some natural-gas bills contain charges that are not simply calculated by multiplying current consumption by a commodity rate.

Depending on the provider, these may appear as:

• Customer charge
• Basic service charge
• Monthly service charge
• Fixed charge
• Facilities-related charge

EIA notes that residential natural-gas prices can include customer and fixed charges associated with transportation and distribution. :contentReference[oaicite:2]{index=2}

4. Did a Purchased-Gas Adjustment or Similar Charge Change?

Some regulated natural-gas utilities periodically adjust charges to reflect changes in their cost of obtaining gas.

EIA explains that state utility commission processes can cause retail natural-gas rates to change later than wholesale market prices. It also describes purchased-gas adjustment mechanisms used by many local distribution companies. :contentReference[oaicite:3]{index=3}

Depending on your utility and jurisdiction, a bill may use different terminology for these adjustments.

Look for wording such as:

• Gas cost adjustment
• Purchased gas adjustment
• Cost-of-gas adjustment
• Fuel adjustment
• Rate adjustment
• Rider

5. Are You Buying Gas From a Separate Supplier?

In some U.S. states and service areas, customers may have a choice of natural-gas supplier.

EIA explains that under customer-choice programs, a marketer may sell the natural gas while the local distribution company continues delivering it. In those situations, gas-purchase costs may be shown separately from distribution and delivery costs. :contentReference[oaicite:4]{index=4}

If this applies to your account, check:

• Your supplier name
• Your current supplier rate
• Whether a fixed rate ended
• Whether an introductory rate expired
• Whether the rate is variable
• Any applicable contract terms

Customer-choice availability and program rules vary widely by state and service territory.

6. Did the Number of Billing Days Change?

Usage may look “about the same,” but a longer billing period can make comparisons less straightforward.

For example:

• Previous: 70 therms over 28 days
• Current: 73 therms over 34 days

Total usage is similar, but average daily usage actually declined.

Calculate:

Average daily usage = gas usage ÷ billing days

This is especially useful when comparing bills with different meter-reading dates.

7. Did a Credit or Discount Disappear?

A bill can increase even if no new fee was added.

Sometimes the change is a credit that appeared previously but is no longer present.

Compare:

• Account credits
• Promotional credits
• Assistance credits
• Billing corrections
• Refund adjustments
• Other utility-specific credits

Do not assume that a missing credit was supposed to continue. Check its description and eligibility terms.

8. Is a Previous Balance Included?

The amount due may be higher than the cost of the current billing period.

In this example, saying “this month’s gas cost $147” would be misleading. Only $105 represents the fictional current charges.

9. Check Taxes, Fees and Other Charges

EIA notes that consumer natural-gas prices can include taxes and fees in addition to commodity and transmission/distribution costs. :contentReference[oaicite:5]{index=5}

Compare every line item on the two bills.

Look for:

• Taxes
• Municipal charges
• Utility-specific fees
• Regulatory-related line items
• One-time charges
• Account adjustments

Which charges apply—and what they are called—depends on the location and utility.

10. Was the Meter Reading Estimated or Corrected?

EIA’s residential-energy terminology notes that gas consumption for a billing period is usually determined from meter readings, but consumption can sometimes be estimated. :contentReference[oaicite:6]{index=6}

Look for words such as:

• Actual
• Estimated
• Corrected
• Adjusted

If you don’t understand the reading status or a correction, ask the utility to explain exactly how the consumption on the bill was determined.

Why Can Retail Gas Prices Change Later Than Wholesale Prices?

You may hear that wholesale natural-gas prices have fallen and wonder why your household rate did not immediately fall too.

EIA explains that residential retail prices can lag wholesale natural-gas price changes. Utilities may purchase gas ahead of time, and regulated rate adjustments can occur on schedules determined through state regulatory processes. :contentReference[oaicite:7]{index=7}

That means today’s wholesale market price is not necessarily the price reflected immediately on your residential bill.

Could Fixed Charges Make the Price Per Therm Look High?

Yes. Be careful when dividing your entire bill by the number of therms used.

The total bill can contain fixed customer charges, distribution costs, taxes and other amounts in addition to the gas commodity cost.

EIA has noted that when fixed costs are spread across smaller consumption volumes, the apparent residential price per unit can rise even though those fixed costs did not increase proportionally with usage. :contentReference[oaicite:8]{index=8}

What Should You Compare on Two Gas Bills?

What Should I Ask My Gas Utility?

If the reason still isn’t clear, ask the company that issued the bill to explain the difference line by line.

Useful questions include:

• Did my gas commodity or supply rate change?
• Did my delivery rate change?
• Did my fixed monthly charge change?
• What does this adjustment or rider mean?
• Was my meter reading actual or estimated?
• Does the bill contain a correction from an earlier period?
• Does my total include a previous balance?
• Am I purchasing gas from a separate supplier?

Bottom Line

If your gas bill is high but usage is the same, don’t spend all your time looking for ways to reduce consumption.

First verify that therms or other gas units really stayed similar. Then compare the commodity rate, delivery/distribution charges, fixed charges, adjustments, taxes, credits and previous balance.

Natural-gas retail pricing is local and can involve utility regulation, supplier arrangements and multiple bill components. The fastest way to find the cause is usually a line-by-line comparison of two bills.
