Introduction: Why Electricity Plan Types Matter
If you live in a deregulated electricity market, you've likely seen two common types of plans: fixed-rate and variable-rate. While the names sound self-explanatory, the impact on your monthly bill, savings, and stress level can be significant.
At Cost Effective, we use AI to analyze your address and recommend the best-value plan based on your usage pattern. But to understand our recommendations, it's important to know the difference between fixed and variable plans and which is right for you.
What Is a Fixed-Rate Electricity Plan?
A fixed-rate electricity plan locks in a single price per kilowatt-hour (kWh) for the entire contract period, typically 6, 12, or 24 months.
✅ Pros:
- Stable pricing (no surprises)
- Easy budgeting
- Ideal for consistent electricity use
❌ Cons:
- May be slightly higher than promotional variable rates
- Early termination fees if you switch before the term ends
Best for: Homeowners, renters with long leases, small businesses with consistent usage, anyone who wants price stability
What Is a Variable-Rate Electricity Plan?
A variable-rate plan changes the price per kWh monthly, based on the market. Rates may rise or fall depending on supply and demand.
✅ Pros:
- Can save money when market rates are low
- Often no long-term contract (more flexible)
- Good for short-term renters
❌ Cons:
- Monthly bill can fluctuate
- Risk of rate spikes (especially during peak seasons)
Best for: Short-term renters, customers with low or flexible electricity use, risk-tolerant shoppers, those switching soon
Key Differences at a Glance
| Feature | Fixed-Rate Plan | Variable-Rate Plan |
|---|---|---|
| Price Stability | ✓ Yes | ✗ No |
| Contract Length | 6–24 months | Month-to-month (usually) |
| Risk of Price Hikes | Low | High |
| Early Termination Fees | ✓ Yes (often) | ✗ Rarely |
| Flexibility | Less flexible | Highly flexible |
| Ideal For | Long-term budgeting | Short-term or seasonal renters |
So... Which Plan Is Better?
That depends on your lifestyle, risk tolerance, and energy usage pattern.
- Love predictability and plan to stay put? → Go with a fixed-rate plan
- Hate commitments and want to ride the market? → Try a variable-rate plan
But here's the twist: sometimes a fixed-rate plan can cost less over time, even if it looks slightly higher upfront—especially in volatile markets or hot summers. That's where AI can help you decide.
How Cost Effective Finds the Right Plan for You

Instead of picking between fixed and variable on guesswork, you get a data-backed recommendation for the most cost-effective option.
Real Example: The "Smart Lock-In"
Sarah in Houston opted for a fixed-rate plan in April 2024 right before summer price hikes. By locking in early, she saved over $180 compared to friends on variable plans who saw massive increases in July and August.
"I didn't realize how much rates could swing. I'm glad I didn't gamble on the market." — Sarah, Houston TX
