Home Energy & Bills Calculators

Every worthwhile energy upgrade — solar, batteries, heat pumps, insulation — depends on knowing your baseline consumption first. The home energy calculator is the right starting point: it maps your total annual usage and monthly cost across appliance categories so you know which systems drive your bill. Most households are surprised to find that heating, water heating, and dryers account for 60-70% of usage, while lighting and electronics are a fraction of that.

Once you have a usage baseline, the next step is diagnosing what your electricity bill actually contains. The bill breakdown calculator separates energy charges from fixed fees, demand charges, and taxes. This distinction is critical: efficiency upgrades and solar only reduce the energy-charge portion, not fixed costs — so knowing that split prevents overestimating your savings before you invest.

With a clear picture of usage and charges, you can test specific savings actions. The time-of-use savings calculator models how shifting laundry, dishwashing, and EV charging to off-peak hours affects your bill under your utility's rate plan — typical savings are 10-20% on energy charges. For homes with high heating or cooling costs, the insulation savings calculator estimates annual savings from upgrading attic, wall, or crawlspace R-values; most attic upgrades pay back in 3-7 years. Taken together, this three-step progression — measure, diagnose, act — turns a vague sense that your bill is high into a prioritized list of changes worth making.
