Fixed vs. Variable Electricity Rates: What Each One Actually Protects You From

If you live in one of the roughly 18 states (plus D.C.) with a deregulated retail electricity market, you're not just choosing a supplier — you're also choosing between a fixed-rate and a variable-rate contract, and that choice usually matters more than which logo is on your bill. Here's what each one actually does, and doesn't, protect you from.

The core difference

| | Fixed-rate plan | Variable-rate plan | |---|---|---| | Rate per kWh | Locked for the contract term (commonly 6, 12, or 24 months) | Can change monthly or seasonally at the supplier's discretion | | Predictability | High — same rate regardless of wholesale market swings | Low — rate can rise (or fall) with wholesale power and gas prices | | Typical starting rate | Often slightly higher than an introductory variable rate | Often lower up front, sometimes as a short-term "teaser" | | Early termination fee | Common, often $100–$200+ if you cancel before the term ends | Usually none or minimal, since there's no rate to "lock out" of | | Best protects against | Rate spikes during high-demand periods (summer heat waves, winter cold snaps, natural gas price surges) | Being stuck in an above-market fixed rate if wholesale prices fall |

Why the fixed-rate case has gotten stronger since 2022

National average residential electricity prices have risen substantially over the past several years, from about 15 cents/kWh in 2022 to roughly 18–19 cents/kWh in mid-2026. Natural gas prices, rising demand from data centers and electrification, and grid-hardening investment are the primary drivers behind that trend. In a period of sustained upward pressure, a variable-rate plan without a cap exposes you directly to that trend, month over month, while a fixed-rate contract insulates you from it for the length of the term.

That doesn't mean fixed is automatically the right choice — it means a variable rate is a bet that prices will fall or stay flat, and that bet has gone against consumers more often than not in the past several years.

A worked 12-month comparison

The situation: A household uses 1,000 kWh per month. They're choosing between a 12-month fixed plan at 14.5¢/kWh and a variable plan that starts at 12.0¢/kWh but resets monthly with the wholesale market.

| Month | Fixed plan rate | Fixed plan cost | Variable plan rate (illustrative) | Variable plan cost | |---|---|---|---|---| | 1 | 14.5¢ | $145 | 12.0¢ | $120 | | 4 (summer demand rises) | 14.5¢ | $145 | 15.5¢ | $155 | | 7 (peak summer) | 14.5¢ | $145 | 18.0¢ | $180 | | 10 (demand cools) | 14.5¢ | $145 | 13.0¢ | $130 | | 12-month total (illustrative) | 14.5¢ avg | $1,740 | ~14.8¢ avg | $1,776 |

In this illustration, the variable plan's low starting rate was more than offset by summer spikes, ending narrowly behind the fixed plan over the full year — even though it looked cheaper in month one. The actual numbers for your household depend entirely on your specific supplier's variable-rate history and your usage pattern by month, so treat this as an illustration of the mechanism, not a universal outcome; some years variable rates do finish ahead.

What a rate lock doesn't protect you from

A fixed per-kWh rate only covers the supply/energy charge. It typically does not lock in:

• Delivery charges, which are usually set by the regulated utility (not your competitive supplier) and can rise independent of your supply contract
• Taxes and regulatory fees, which apply regardless of supplier or plan type
• Monthly base/customer charges, if your specific plan includes one

This is why a plan's advertised rate isn't the same as your total bill — see our guide to reading your electric bill for how supply and delivery charges are typically split out.

The fine print worth checking before you sign

| Item | Why it matters | |---|---| | Early termination fee | If you might move, downsize usage significantly, or want to switch suppliers again, a high cancellation fee can erase any savings from switching | | "Teaser rate" duration | Some variable plans advertise an intro rate for the first 1–2 billing cycles only, before reverting to a higher standard variable rate | | Renewal terms | Many fixed contracts auto-renew onto a variable (often higher) rate if you don't act before the term ends — mark your contract end date | | Minimum usage fees | Some plans charge a penalty if your usage falls below a threshold, which matters if you're adding solar or cutting usage significantly |

FAQ

Is a fixed rate always more expensive than a variable rate? Not always — it depends on the specific rates offered and how wholesale prices move during your contract term. Fixed plans trade a potentially lower average cost for certainty; variable plans trade certainty for a chance at a lower cost, with real risk of the opposite outcome.

What happens if I break a fixed-rate contract early? Most fixed plans include an early termination fee, often in the $100–$200+ range depending on the supplier and remaining contract length — check your specific contract's terms before signing, since these vary widely.

Can I switch from variable to fixed mid-contract without a fee? Often yes, since variable plans typically don't carry the same lock-in penalties as fixed plans — but confirm with your specific supplier, as terms vary.

Does my state even offer a choice of supplier? Only about 18 states plus D.C. have retail electricity choice; in the rest of the country, your utility is both your supplier and your delivery provider, so this comparison doesn't apply. Check your state's public utility commission site to confirm your state's status.
