Buyers shopping for an electric car are closer than ever to price parity with gasoline models after lithium-ion battery pack costs dropped to $108 per kilowatt-hour, according to BloombergNEF. The decline, the steepest annual fall since 2017, landed even as some raw-material prices moved higher, signaling that manufacturing scale and fierce competition among cell producers are now the dominant forces driving costs down. For automakers and consumers alike, the $108 figure reshapes the math on whether a battery-electric vehicle can compete on sticker price without heavy subsidies.
Why a $108 pack price changes the EV cost equation
Battery packs account for roughly a quarter to a third of an electric vehicle’s total cost. Every dollar shed per kilowatt-hour translates directly into lower retail prices or wider profit margins for manufacturers. The drop to about $108, per BloombergNEF’s annual survey, represents a sharp acceleration from the $115 per kWh level the same survey recorded in 2024. That $7 per kWh swing on a typical 60 kWh sedan pack means several hundred dollars less in battery expense per vehicle, a margin shift large enough to influence model-level pricing decisions at major automakers.
The speed of the decline matters as much as the number itself. Industry forecasts published as recently as two years ago placed the sub-$100 threshold somewhere after 2026. Reaching $108 ahead of that timeline puts pressure on automakers still planning internal-combustion launches to reconsider their product mix, and it gives EV-focused brands room to cut prices or add features without sacrificing margins. In practical terms, a mainstream compact EV with a 50 to 60 kWh pack can now be priced much closer to an equivalent gasoline model while preserving profitability, especially in markets with tax credits or purchase incentives.
One question embedded in the data is whether the drop concentrates in full battery-electric vehicle packs or spreads evenly to plug-in hybrids. Cell oversupply in Asia has been most acute among high-nickel chemistries, the formats that dominate large BEV packs. Plug-in hybrid packs tend to be smaller and often use different cell formats, so the surplus may not benefit them equally. The battery chapter of the IEA’s Global EV Outlook 2025 segments analysis into BEV and PHEV categories and draws on BloombergNEF survey inputs, but publicly available tables do not break the $108 figure into separate BEV and PHEV averages. That gap leaves open the possibility that the headline number overstates the savings available to plug-in hybrid buyers while understating how cheap full-EV packs have actually become.
BloombergNEF survey data and the IEA’s analytical framework
The $108 per kWh figure originates from BloombergNEF’s annual battery price survey, a volume-weighted poll of cell and pack manufacturers, automakers, and other industry participants. According to BloombergNEF, the survey captured the biggest single-year price drop since 2017, a period when lithium carbonate and cobalt prices were also falling sharply. What distinguishes the latest decline is that it occurred despite rising metal prices in some categories, pointing to efficiency gains in cell manufacturing, higher factory utilization rates, and aggressive pricing by Chinese producers competing for export share.
BloombergNEF’s methodology aggregates contract prices across chemistries, form factors, and regions, weighting results by the volume of batteries sold. That approach is designed to reflect what large automakers actually pay rather than the spot prices smaller buyers might see. However, because the full respondent list and weighting scheme are proprietary, outside analysts cannot reconstruct the exact mix of contracts that produced the $108 average. The result is a widely cited benchmark that still carries a degree of opacity.
The IEA’s Global EV Outlook 2025, the most widely referenced institutional report on electric-vehicle market trends, relies in part on those BloombergNEF inputs for its battery-cost assumptions. The IEA treats pack-level pricing as the standard industry benchmark, distinguishing clearly between cell costs and complete packs that include cooling systems, structural housings, wiring, and control electronics. For vehicle buyers, pack-level pricing is what matters: it represents the total battery expense embedded in the car’s bill of materials and, ultimately, its showroom price.
Two numbers circulate in public reporting and deserve careful distinction. BloombergNEF’s survey showed pack prices at $115 per kWh in 2024, and a later data point places them at $108 per kWh. The difference appears to reflect updated survey timing or a broader sample that includes the most recent procurement contracts. Both figures come from the same research provider, and neither has been publicly contradicted by other major trackers, but the gap highlights how sensitive the headline number is to which contracts and which regions are weighted most heavily.
Unresolved questions about the $108 benchmark
Several pieces of the cost picture remain unclear. No primary IEA dataset or publicly available table reproduces the $108 per kWh figure directly; the number traces back to BloombergNEF’s proprietary survey, and the full methodology has not been released in open-access form. That limits independent verification of the volume-weighted average and leaves analysts reliant on a single commercial source for one of the most important metrics in the EV transition.
Regional variation is another blind spot. Pack prices in China, where the bulk of global cell production is concentrated, are widely understood to be lower than prices in Europe or North America, in part because Chinese manufacturers enjoy scale advantages and a denser local supply chain. If Chinese contracts make up a disproportionate share of the survey’s volume weighting, the global average could skew lower than what Western automakers actually pay for similar packs. Conversely, if the survey tilts toward higher-priced markets, it might understate how inexpensive packs have become in China’s intensely competitive domestic EV segment.
There are also open questions around chemistry and form factor. The rapid build-out of lithium iron phosphate (LFP) capacity, especially in China, has pushed down prices for that chemistry faster than for high-nickel cells used in long-range and premium vehicles. Prismatic and blade-style cells, which simplify pack assembly by reducing the number of modules and components, can further cut pack-level costs. Without a public breakdown by chemistry and format, it is difficult to know how much of the $108 figure reflects these lower-cost technologies versus more expensive cells destined for performance-oriented models.
For automakers, these uncertainties complicate planning. A company that sources most of its batteries from higher-cost regions or sticks with premium chemistries may not realize the full benefit of the global average price decline. That can influence decisions about where to locate new battery plants, which suppliers to partner with, and whether to prioritize cost-optimized mass-market models or higher-margin premium EVs.
Policy makers face similar challenges. Many government targets for EV adoption assume continued declines in battery costs, often benchmarked to industry averages like BloombergNEF’s. If those averages are materially lower than what domestic manufacturers pay, subsidies and tax credits may not stretch as far as expected. On the other hand, if local industries can close the gap with the most efficient producers, the latest price trends suggest that EVs could reach unsubsidized price parity with combustion vehicles sooner than earlier forecasts implied.
Despite the unanswered questions, the direction of travel is clear. Battery packs are getting cheaper at a pace that outstrips most recent projections, and manufacturing scale rather than raw-material volatility now appears to be the main driver. As more detailed data emerges from both commercial surveys and institutional reports, the industry will gain a sharper view of how evenly the benefits of the $108 benchmark are distributed-and how quickly that figure might fall below the psychologically important $100 threshold.
