📊 Factors That Affect Your Electricity Bills
1. Seasonal Variations
Usage changes with seasons: summer peaks due to AC, winter spikes from electric heating.
2. Time-of-Use Rates
Peak hours (4 PM – 9 PM) usually cost more. Shift usage to off-peak hours to save.
3. Tiered Pricing
Rates may increase as usage rises (e.g., higher per-unit cost above 500 kWh).
4. Demand Charges
Commercial accounts may pay separate fees for peak instantaneous usage.

Frequently Asked Questions
What if I don't know my kWh usage? ▼
Check your electricity bill—it's always listed. If you can't find a physical bill, log into your utility company's online account or app, where you can see your daily, monthly, and annual usage history. Many utilities provide this data going back several years.
Should I use average kWh or current month kWh? ▼
It depends on what you want to estimate. Use your current month's kWh if you want to know next month's likely bill (assuming similar usage). Use your 12-month average for a year-round estimate. Use last month's kWh to predict this month if usage patterns are consistent.
Why is my estimate different from my actual bill? ▼
Several factors could explain the difference: (1) Tiered pricing—your rate may increase as usage rises, (2) Taxes and fees—most bills include surcharges beyond the base rate, (3) Demand charges—commercial customers pay for peak instantaneous usage, (4) Seasonal rate changes—rates sometimes change between seasons, (5) Rounding—utilities may round to nearest cent.
How can I find my exact electricity rate? ▼
Check your most recent bill—the rate is usually shown as $/kWh or ¢/kWh. If you can't find it, calculate it: Total Bill Amount ÷ Total kWh Used = Your Rate. Or contact your utility company directly—they can provide your exact rate and explain any tiered pricing.
Can I use this estimator for a year of usage? ▼
Yes! Simply use your annual kWh (found on your utility's annual summary or by adding 12 months of bills). Enter your average rate and you'll see your annual cost. This is useful for budgeting, comparing utilities, or evaluating whether to install solar panels.
