Early Termination Fee Calculator: When Switching Plans Saves You Money

You found a cheaper electricity plan. But there's a catch: your current contract isn't up for another eight months, and your provider wants $150 to let you go.

Is it worth paying the fee? That depends on how much you'd save each month on the new plan. A $150 early termination fee sounds steep until you realize it could pay for itself in four or five months. After that, every dollar saved is yours to keep.

This guide walks you through the math. We built a breakeven calculator that compares your current rate, your early termination fee, and real plan pricing in your ZIP code. You'll know in seconds whether switching makes financial sense or whether you're better off running out the clock.

What is an early termination fee on an electricity plan?

An early termination fee (ETF) is a penalty your REP charges if you cancel a fixed-rate contract before it expires. Think of it as the price of breaking your agreement early. The fee is spelled out in your plan's EFL, usually under a section labeled "Early Cancellation" or "Early Termination."

Not every plan has one. Month-to-month and variable-rate plans typically let you leave anytime. Fixed-rate contracts, the kind that lock in your price for 12, 24, or 36 months, almost always include an ETF. The longer the contract, the higher the fee tends to be.

How much are early termination fees in Texas?

Most Texas electricity ETFs fall between $99 and $395, depending on the provider and contract length. The most common fee for a 12-month plan is $150. Longer contracts (24 or 36 months) typically charge $250 to $395.

The table below shows what major providers charge, based on provider disclosures and publicly available EFL data.

Notice the two different fee structures? That distinction matters more than you might expect. We'll break it down in the next section.

What are the two types of early termination fees?

Texas electricity providers use two ETF structures, and the type you have changes when it makes sense to switch.

Flat-fee ETFs charge the same amount regardless of when you cancel. Leave with one month left or eleven months left. You pay $150 either way. TXU, Reliant, and Gexa all use this model.

Per-month-remaining ETFs decrease as your contract winds down. At $20 per month remaining, canceling with 3 months left costs $60 instead of $150. Providers like 4Change, Rhythm, and Chariot use this structure.

The crossover point between the two structures is about 7–8 months. The table below shows exactly how they compare:

If you're on a per-month-remaining plan with only a few months left, your ETF could be low enough that switching is almost a no-brainer. With a flat-fee plan, the math is the same whether you cancel in month 2 or month 11.

When is it worth paying an early termination fee to switch?

The breakeven formula is straightforward:

Months to breakeven = ETF ÷ monthly savings

Your monthly savings come from the difference between your current rate and the new plan's rate, multiplied by your typical monthly usage. If the breakeven point is fewer months than what's left on your contract, switching saves you money overall.

A worked example: say you're paying 16.0¢/kWh (close to the Texas average of 16.04¢/kWh as of November 2025, per the EIA) and you use about 1,000 kWh per month. You find a 12-month plan at 12.7¢/kWh, the best-value rate in the Dallas area as of February 2026 (similar rates are available in Houston and Fort Worth). Your ETF is $150.

• Rate difference: 16.0¢ − 12.7¢ = 3.3¢/kWh
• Monthly savings: 3.3¢ × 1,000 kWh = $33/month
• Breakeven: $150 ÷ $33 = about 5 months
• Annual net savings: ($33 × 12) − $150 = $246

Five months to break even. If your contract has more than five months left, you come out ahead. If it has fewer than five months left, you're better off waiting until it expires and switching then, no fee required. You can compare plans for 75201 to see what's available right now.

But you don't have to do this math by hand. The calculator below pulls real plan rates for your ZIP code and runs the numbers automatically.

Calculate your breakeven point

Enter your current rate, your early termination fee, and your monthly usage below. The calculator shows how many months each available plan takes to pay back your cancellation fee, sorted from fastest breakeven to slowest.

Green badges mean the plan pays for your ETF in 6 months or less. Amber means 7–12 months. If nothing shows green, your current rate might already be competitive. Consider waiting for your contract to expire.

How can you avoid paying an early termination fee?

Texas law and provider policies give you several ways to switch without paying a penalty.

Use the 14-day window. Your provider must notify you at least 30 days before your contract expires. Once that notice arrives, you can switch to any provider without an ETF starting 14 days before the expiration date. Mark your calendar when you get that letter.

Move to a new address. Under PUCT Substantive Rule §25.475(c)(2)(C), your electricity contract is tied to a specific address. If you relocate, you're under no obligation to continue the contract at your new home. Your provider may ask for a forwarding address and proof of the move, but they cannot charge an ETF.

Cancel within the 3-day cooling-off period. If you recently switched to a new plan, PUCT rules give you 3 federal business days after receiving the Terms of Service to rescind your enrollment, no fee, no questions. This applies to switch transactions only, not new service activations.

Watch for material changes. If your provider changes the terms of your contract (common with variable-rate add-ons), you have 14 days to cancel without penalty after receiving the notice.

Look into satisfaction guarantees. Several providers offer trial periods: TXU Energy gives you 60 days to cancel or switch plans with no ETF. 4Change Energy offers 60 days as well. Rhythm Energy has a 30-day "Test Drive" that lets you walk away penalty-free. Reliant, Gexa, and Frontier have 60–90 day windows, but only for switching to another plan within the same provider. Leaving entirely still triggers the fee.

Choose a no-ETF plan next time. When your current contract does expire, consider a month-to-month or short-term plan that doesn't penalize you for leaving. You might also look at bill credit plans, which can offer lower effective rates at certain usage levels. The tradeoff with no-ETF plans is that rates may be slightly higher than long-term fixed plans, but you gain flexibility.

What does the PUCT say about your switching rights?

The Public Utility Commission of Texas sets the rules for how electricity contracts and termination fees work in the deregulated market. PUCT requires that every ETF be clearly disclosed in your EFL and Terms of Service. If it's not written there, your provider can't charge it.

Additional ETF exemptions exist for extreme financial hardship, death in the family, and active-duty military personnel under the federal Servicemembers Civil Relief Act (SCRA). If any of these apply to you, contact your provider and reference the applicable regulation.

One thing PUCT does not do: cap the dollar amount of an ETF. The commission requires disclosure, not a maximum. Some providers charge $99; others charge $395. Your only protection is knowing what you agreed to when you signed up. If you believe a provider is charging an undisclosed fee, you can file a complaint with PUCT.

What should you check on your EFL before switching?

Before you plug numbers into the calculator, grab your current plan's EFL. You can usually find it in your online account or by calling your provider. You need four things from it.

Your current rate per kWh. The EFL shows average prices at 500, 1,000, and 2,000 kWh. Use the one closest to your actual monthly usage. This is the number you'll enter into the calculator as your "current rate."

The exact ETF amount. Look for the "Early Cancellation" section. Note whether it's a flat fee or per-month-remaining. This affects your calculation if you're comparing the cost of leaving now versus a few months from now.

Your contract end date. If you're within 14 days of expiration, you can switch for free. No need to pay an ETF at all.

Whether the rate includes TDU delivery charges. The EFL's average price at each usage level includes both your REP's energy charge and your TDU's delivery charge. When comparing plans, make sure you're comparing all-in rates, not just the energy portion.

Frequently asked questions

Find plans worth switching to

Early termination fees are a real cost, but they aren't always a reason to stay on an expensive plan. A $150 fee that pays for itself in 5 months leaves you with $246 in savings over the first year alone. The key is running the breakeven math before you decide. Compare plans at your usage level to see what you could be saving.

And when your contract does expire, whether you wait it out or pay the fee, don't let it roll into a month-to-month variable rate. That's where the real money gets wasted.
