How to read the outputs
Installed battery cost
battery plus installation. Default preview: $7,500.00.
Usable stored energy
90% usable depth. Default preview: 12.15 kWh.
Lifetime delivered energy
6,000 full modeled cycles. Default preview: 67,068 kWh.
Capital cost per delivered kWh
installed cost only. Default preview: $0.11.
Charging cost per delivered kWh

Combined cost per delivered kWh
capital plus entered charging energy. Default preview: $0.31.
Methodology
Transparent calculation
BuildMeter converts every input to a consistent internal unit, applies the selected allowance, and rounds products up to whole purchasable units.
Delivered energy per cycle = nominal capacity × usable depth × round-trip efficiency. Capital cost divides installed cost by rated cycles or lifetime delivered energy.

FAQ
Battery Cost per Cycle Calculator questions
What is a full equivalent cycle?+
Partial charge and discharge events can be combined into the equivalent of one full cycle.
Will every battery deliver its rated cycle life?+
Not necessarily. Temperature, power rate, depth of discharge, calendar age and controls affect life.
Why include charging energy cost?+
Stored energy must be purchased or generated, and round-trip losses increase the input energy required.
