A signup deadline and a contract expiration are different dates. Your renewal terms determine what happens after the initial plan; today’s published price is a comparison reference.
Know which date is expiring
A promotion’s enrollment deadline is the last date you can sign up under that offer. Once enrolled, a fixed contract’s stated term determines how long its contracted price applies. A variable introduction may instead cover only one or two bills.
Keep your confirmation and terms, then record your own contract end date. Check your marketer’s renewal notice before that date, including the new therm rate, service fee, term and what happens if you take no action.
AGL’s rate guidance ↗ notes that a marketer may move a customer to variable pricing after a fixed plan expires if the customer does not notify the marketer beforehand. The outcome depends on your plan’s terms.
Compare the whole renewal offer
- Is the new price fixed or variable?
- What is the new monthly service fee?
- Does the new offer require another contract?
- Do introductory credits, rewards or waived fees end?
- Can you select a different plan or marketer, and when?
A standard published price is not a promised renewal quote. Your marketer may offer a different renewal price, and prices can change before your term ends.

A 12-month introduction followed by four years at a reference price
Assume 600 therms per year, a 60¢ initial rate, an 80¢ reference renewal rate and a $7 monthly fee in both periods. Assume no credits.
Each later year: 600 × $0.80 + 12 × $7 = $564
Five-year scenario: $444 + 4 × $564 = $2,700
Holding the introduction at 60¢ for all five years would instead show $2,220, understating this scenario by $480.
This example excludes AGL delivery, taxes and one-time fees, and holds usage and reference prices constant. It illustrates the calculation, rather than forecasting a bill.
How our five-year comparison works
The calculator applies the selected offer for its initial term, then uses the saved published price and highest listed monthly fee for the corresponding plan through month 60. An 18-month plan therefore gets 18 months at its initial price and 42 months at the reference price.
For fixed plans, each month uses annual therms divided by 12. Eligible one-time credits are counted once. Actual heating usage is seasonal, so a contract that spans part of a year can cost differently from this average-month assumption.
This answers “What would staying with this marketer cost under these assumptions?” It cannot guarantee the rate you will be offered or assume that you will qualify for another new-customer promotion. The comparison methodology explains the specific renewal mappings and reward treatment.
Review your options before the term ends
Set a reminder about a month before expiration, then review the renewal notice and current alternatives. Confirm any cancellation fee and the proposed change date before switching. Compare using your recent annual usage and your actual quoted fees.
