Compare Georgia gas plans by total cost

The lowest price per therm is not always the lowest-cost plan for your household. Monthly fees matter more when you use less gas. Use the same usage, time period and eligibility assumptions for every offer, then check delivery charges, taxes and contract costs before making a decision.

Decide which costs you are comparing

Start with the part most directly affected by the offer: therm usage multiplied by the supply rate, plus the monthly marketer service charge. Then account for any enrollment costs, cancellation fees and credits you actually qualify for. For a full-bill quote, include delivery charges, taxes and all other applicable costs.

A comparison of supply and service fees is useful, but it must not be labeled a total bill. AGL delivery charges remain relevant to the household budget even when they do not change between marketers at the same premises and billing period. Ask each marketer for a quote using your therm usage and DDDC.

Three usage levels can reverse the winner

Consider two hypothetical fixed plans for the same service address. Plan A charges $0.60 per therm plus $12 a month. Plan B charges $0.70 per therm plus $6 a month. Assume those charges stay unchanged for the comparison period. Neither plan represents a current enrollment offer.

50 therms$42.00$41.00B by $1.00
100 therms$72.00$76.00A by $4.00

Find the break-even usage

Plan A saves $0.10 per therm but costs $6 more each month. Divide the extra fee by the rate saving: $6 ÷ $0.10 = 60 therms. At 60 therms, both plans cost $48 before delivery and taxes. Below 60, Plan B’s lower fee wins; above 60, Plan A’s lower supply rate wins.

This shortcut works when one plan has a lower supply rate and a higher fixed monthly fee. If a plan is lower on both, no usage crossover is needed for those two components. Tiered pricing, variable rates, conditional discounts or changing fees require a more detailed month-by-month comparison.

Use annual usage to avoid a seasonal mistake

A winter-only comparison can favor a low rate with a high fee, while a summer-only comparison can do the reverse. For twelve months at unchanged rates, calculate annual supply plus twelve monthly fees. If your home uses 800 therms in a year, Plan A costs $480 + $144 = $624; Plan B costs $560 + $72 = $632. Plan A’s annual advantage is only $8 before other costs.

At 600 annual therms, the same calculation gives $504 for A and $492 for B. At 1,200 therms it gives $864 for A and $912 for B. These scenarios show why your usage matters more than the order of two advertised supply rates. They are arithmetic examples, not forecasts of your consumption.

For variable or introductory pricing, enter the applicable rate for each month rather than multiplying the opening rate by a full year. If future rates are unknown, show several explicit scenarios; do not present one assumed path as guaranteed savings.

Check the terms before treating an offer as available

The PSC pricing charts define a comparison customer; that customer may not match your home. Georgia Gas Resources’ filed-rate sort ranks supply prices. An estimated-bill sort answers a different question using its displayed assumptions. Confirm the effective date and plan details, then compare against your actual bill.

Keep screenshots or a dated copy of the final offer and agreement. A website headline can change after enrollment. Check your first statement for the agreed supply rate and fees, and note the renewal decision deadline so an introductory deal does not become an unnoticed price change.

  • Match the service area, term and customer eligibility.
  • Confirm whether autopay or another condition is required for the quoted rate.
  • Read service fees, deposit requirements and cancellation terms.
  • Count credits only when you meet the conditions; include their timing.
  • Compare the same number of months and retain the written offer.

Put your comparison into practice

Check current published plans, then ask the marketer to confirm the offer for your address, usage and eligibility.
