Bill breakdown estimator
Turn one bill into a clear picture of where your energy dollars go.
Enter your average bills, rates, climate, and fuels. We estimate the split across heating, cooling, water heating, and plug loads so you know what to fix first.

Assumptions & how to use this
We use climate, fuel, and occupancy to shape realistic shares instead of national averages.
If you heat with gas, the electric split focuses on cooling, hot water (if electric), and plug loads.
Change the rate fields if your utility prices differ—watch the shares update instantly.
Use the biggest slice as your first target: tighten the shell before upsizing equipment.
