Notes for the reader
A useful estimate starts
with clear boundaries.
Your input sets the detail
A usage CSV lets the tool work with the hours you used electricity. Monthly kWh can calculate supported flat rates without inventing an hourly profile.
Prepare your usage fileEvery estimate has a scope
Historical mode uses verified rates for the applicable dates. A scenario applies selected rates to your profile. Missing charges stay visible; incomplete estimates receive no total-cost winner.
