Battery Cell Cost per kWh Calculator
The cell is the fundamental electrochemical building block of a battery, and cell cost per kWh is the single most important driver of finished battery economics -- which is why the choice between LFP (lithium iron phosphate) and NMC (nickel manganese cobalt) chemistry has become so consequential. This calculator estimates the total cell cost of a battery pack from the cell cost per kWh and the pack capacity, with the cell cost per kWh pre-filled by chemistry (LFP at $70/kWh, NMC at $90/kWh) and still editable so you can substitute a project-specific figure. It pairs naturally with our Battery Mineral Cost per kWh Calculator for the raw mineral cost that sits underneath the cell cost, and our planned Domestic vs. Imported Battery Cost Comparison Calculator for the sourcing-side cost comparison.
Selecting a chemistry auto-fills the cell cost per kWh below with a representative 2026 planning-level estimate; the cell cost per kWh remains editable for project-specific figures.
2026 industry data shows LFP cells commonly priced $60-80/kWh and NMC cells $80-100/kWh -- LFP has become the dominant chemistry for stationary storage due to its lower cost, longer cycle life, and better safety profile, while NMC remains common in EVs and applications prioritizing higher energy density.
The total energy capacity of the battery pack being costed, in kilowatt-hours.
cell cost per kWh ($/kWh) × pack capacity (kWh)
This is cell cost only, not finished pack or installed system cost. A finished pack adds module hardware, the battery management system, wiring, and thermal management -- typically pushing total pack price 20-40% above cell-only cost. An installed system adds further cost for power conversion equipment, engineering, and construction.

How we calculate this →The gap between LFP and NMC cell cost -- $70/kWh versus $90/kWh in this example -- explains why LFP has become the default chemistry for stationary energy storage, where cost and cycle life matter more than the compact size and weight NMC's higher energy density provides. That's exactly the opposite prioritization from EVs, where NMC's energy density advantage often justifies its cost premium since vehicle range and weight are critical constraints. Average finished battery pack prices across all chemistries and applications fell to around $108/kWh in the most recent industry-wide tracking, continuing a long-term downward cost trend even as raw material prices have been volatile.
How battery cell cost per kWh is calculated
This calculator estimates the total cell cost of a lithium-ion battery pack from the cell cost per kWh and the pack capacity, with the cell cost per kWh pre-filled by chemistry and still editable. One quantity ties the calculation together.
Total Cell Cost ($) = Cell Cost per kWh ($/kWh) × Pack Capacity (kWh). The cell cost per kWh is the price of an individual battery cell expressed per unit of energy storage capacity; the pack capacity is the total energy capacity of the battery pack being costed. Multiplying the two gives the total cell cost for the pack. At the defaults (LFP at $70/kWh and 100 kWh), that is $70 × 100 = $7,000.
Two notes on the model. First, the cell cost per kWh figures are representative 2026 planning-level estimates that vary by chemistry (LFP cells commonly priced $60-80/kWh, NMC cells $80-100/kWh), manufacturer, contract volume, and geography, so the editable field lets you substitute a project-specific figure. Second, this calculator reports cell cost only and does not include the additional cost of assembling cells into a finished pack (module hardware, the battery management system, wiring, and thermal management -- typically adding 20-40% above cell-only cost), the further cost of an installed system (power conversion equipment, engineering, and construction), the raw mineral cost that sits underneath the cell cost (see the Battery Mineral Cost per kWh Calculator), the effect of long-term supply contracts and hedging that mean real-world procurement rarely occurs at spot prices, or the domestic vs. imported sourcing cost comparison once US cell manufacturing capacity comes online (see the planned Domestic vs. Imported Battery Cost Comparison Calculator) -- all of which a full battery cost evaluation would include. Data sources: LFP cell cost range ($60-80/kWh) and NMC cell cost range ($80-100/kWh) from BloombergNEF, Benchmark Mineral Intelligence, and IEA battery cost reporting; LFP dominance in stationary storage from BloombergNEF and IEA battery chemistry tracking; average finished battery pack price of around $108/kWh from BloombergNEF annual battery price survey; finished pack cost premium of 20-40% above cell-only cost from BloombergNEF and IEA battery cost breakdowns. Verification: with defaults (LFP, $70/kWh, 100 kWh), Total Cell Cost = $7,000.
