Your bill starts with energy: kilowatt-hours times your rate per kWh. This guide walks through the electricity bill estimator—total monthly kWh from your meter or bill summary, your utility energy rate, and the estimated bill before delivery charges and fixed fees.
Benefits
- Simple formula: bill = kWh × $/kWh.
- Works with any billing period—enter the kWh shown on your statement.
- Baseline check before comparing appliances, TOU rates, or solar offset.
How it works
- Find total kWh used for the billing period on your utility bill or smart meter.
- Enter your energy rate in $/kWh from the rate schedule or bill line item.
- Read the estimated bill—energy charges only, excluding fixed fees and taxes.
FAQ
How do I estimate my electricity bill?
Bill ≈ kWh × $/kWh. Example: 850 kWh at $0.14/kWh → 850 × 0.14 = $119.00 energy charge. Add your utility's fixed monthly fee, delivery rider, and taxes for the full statement—this tool isolates the energy math.
Where do I find my $/kWh rate?
Check the energy charge line on your bill—divide energy dollars by kWh for an effective rate. Tiered or time-of-use plans may blend multiple rates; use a weighted average or your highest tier if you are stress-testing summer usage.
Why is my real bill higher than the estimate?
Most bills include a fixed customer charge, distribution/delivery fees, state taxes, and sometimes demand or fuel adjustments. Tiered rates bill higher kWh blocks at higher $/kWh. This estimator covers energy rate × usage only—the core variable you control with efficiency.
Technical specifications
- Energy bill $ = kWh × rate_$/kWh.
- Effective rate = energy_charge $ ÷ kWh (from statement).
- Annual energy $ ≈ monthly kWh × 12 × $/kWh (flat-rate assumption).
