Electricity Savings Estimate
Natural Gas Savings Estimate
These estimates are based on supply rate differences only. They don't include delivery, transmission, capacity, or taxes, which remain constant regardless of supplier choice. Actual savings depend on your specific load profile and contract terms.

How to Use This Tool
Enter your monthly electricity usage (from your utility bill) and the rate difference you're evaluating. The calculator estimates monthly and annual supply cost savings.
To find your current supply rate: look for "supply charge," "REP charge," or "generation" on your utility bill. It's expressed in cents per kWh. If you're on default service, call your utility or have a broker pull your rate from the usage data.
Realistic rate differences: In competitive markets with 30+ active suppliers, businesses that haven't shopped their supply in 12+ months often find alternatives that are 1–3 cents/kWh lower. For a 100,000 kWh/month account, that's $1,000–$3,000/month.
Beyond the Calculator: Getting Real Quotes
This calculator uses simplified inputs. A broker analysis uses your actual 12-month interval data to model competing offers from real suppliers. The difference: you get specific contract offers with defined terms, not estimates.
The process takes 3–5 business days from data authorization to competing offers. It costs nothing. And the competitive process itself — submitting to 30+ suppliers simultaneously — consistently produces better outcomes than calling suppliers one at a time.
Frequently Asked Questions
Are these calculator results accurate?
The calculators estimate supply cost savings based on rate differences and usage volumes. They don't include delivery, capacity, transmission, or tax components. Actual savings depend on your specific load profile and contract terms. For a precise analysis, submit your bill for review.
What's a realistic rate difference from switching suppliers?
In competitive markets, businesses that haven't run a quote process in 12+ months often find rate differences of 1–3 cents/kWh or more. For a 100,000 kWh/month account, 1.5 cents difference = $1,500/month, $18,000/year.
Do I need my actual utility bill to use these tools?
Not for basic estimates. Your approximate monthly kWh usage (from any recent bill) is enough to run the savings calculator. For precise numbers, provide actual usage history to a broker.
What counts as 'supply rate' vs. 'total rate'?
Supply rate is the commodity cost — the portion you negotiate with retail suppliers. Total rate includes delivery, capacity, transmission, and taxes, which are fixed. Always compare supply rates when evaluating competing quotes.
How do I find out my current supply rate?
Your current supply rate is on your utility bill — sometimes labeled 'supply charge', 'generation', or 'REP charge'. If you're on utility default service, the rate is set by the utility or PUC. A broker can identify your exact current supply rate from your bill.
