All About Total Cost of Ownership (TCO) for Electric School Buses
With lower fuel expenses, reduced maintenance costs and record funding available to offset purchase costs, the total cost of owning an electric school bus can be hundreds of thousands of dollars less than for a diesel-burning school bus.
When thinking about the transition to electric school buses (ESBs), school districts and private fleet operators should not only consider the upfront costs – they should also evaluate the lifetime costs of transitioning their fleet.
Total Cost of Ownership (TCO) is the sum of all current and future capital and operating expenses associated with the ownership of an asset, and it’s an important consideration when purchasing a new school bus.
For school buses these expenses include:
- upfront purchase price of the vehicle
- upfront purchase price and operating cost of refueling infrastructure (e.g. charging infrastructure for an ESB)
- upfront grants or incentives to subsidize purchases
- future annual fuel expenditures
- future cost of maintenance and repair
- registration fees and insurance
- any revenues from energy or environmental market payments
According to Electric School Bus Initiative analysis, a school district operating an ESB can expect to see over $100,000 in lifetime fuel and maintenance savings, compared to an equivalent diesel bus, which can help offset the currently higher purchase price of an ESB.

Comparing electric school bus funding scenarios
Despite near-term fluctuations as the market adjusts to an influx of demand stemming from the Infrastructure Investment and Jobs Act (IIJA) and Inflation Reduction Act (IRA), experts anticipate meaningful upfront price declines over the next decade as battery costs decline and the electric vehicle industry achieves efficiencies of scale in component markets and manufacturing.
From this projected price decline, we anticipate that the lifetime total cost of ownership (TCO) of electric buses, even without subsidies or incentive programs, will achieve cost parity with diesel-burning school buses by the middle of this decade. In the meantime, funding and financing options, such as those detailed in this Clearinghouse of Electric School Bus Funding and Financing Opportunities will remain important.
The analysis includes the cost of a networked 19kW level two charger and associated construction and installation on the customer’s side of the meter. For information on alternative charger options and tradeoffs, see our All About Charging Infrastructure video series.
Electric School Bus (ESB) + 45W Scenario. The first ESB TCO funding scenario includes $40,000 from the 45W IRS tax credit, a provision of 2022’s Inflation Reduction Act, which can be applied to the upfront cost of any electric school bus, bringing the lifetime TCO in this scenario to $530,000. This credit is available as a direct payment to school districts.
ESB + CSBP Priority Rebate Scenario. The second ESB TCO funding scenario includes a rebate equivalent to the full cost of the bus and charger as was available to priority districts in the first rebate award cycle of EPA’s Clean School Bus Program (CSBP). In the CSBP rebate program, a total of $395,000 was available; $362,000 was used in the analysis here, based on a bus purchase price of $352,000 and $10,000 rebate claimed for a charger. This funding brings the lifetime TCO down to $208,000. Similar incentives may be available in future rounds of the Clean School Bus Program or through state or other funding programs.
ESB Multisource Funding Scenario. The last ESB TCO funding scenario includes $169,000 from State Volkswagen (VW) grant, $117,000 from U.S. Department of Agriculture’s (USDA) Community Facilities program and $45,000 from electric utility cooperative funding and demonstrates how stacking funding opportunities can help districts overcome the upfront cost barrier of an ESB and, in this case, bring the TCO all the way down to $200,000. This scenario is inspired by the real-world solution implemented in Knox County, Missouri.
With Clean School Bus Program rebate funding or the types of stacked funding options available today, the TCO for electric school buses can actually be hundreds of thousands of dollars less than the TCO of a diesel-burning school bus – saving districts money that they can reinvest in the classroom, all while eliminating harmful tailpipe emissions.
TCO Calculator and comparison tools
If you’re ready to start comparing options for your district, you can get started with the new Total Cost of Ownership Calculator for Electric School Buses tool developed by the ESB Initiative and Atlas Public Policy.
The TCO Calculator allows you to toggle between scenarios, select example options like Clean School Bus Program rebate round funding, and see location- and charger-specific electricity costs.
For an even more detailed and customizable TCO calculation, we recommend you use Atlas Public Policy’s updated Fleet Procurement Analysis Tool, linked below. The ESB Initiative has prespecified this tool for Type A, Type C and Type D models. You can download the Excel tool that best fits your district’s needs below, along with the user guide to assist with your use of this tool:
The ESB Initiative has also developed a Technical Note as a reference guide for those conducting the TCO analysis of diesel and electric school buses. The Technical Note provides users recommended default specifications for key calculation parameters. The recommendations, based upon publicly available information, can increase your confidence in the results of analysis undertaken to assess the economics of fleet electrification. Please note that the ESB Initiative recommends that users use more specific data to reflect local situations where such data are available. Get the Technical Note here.
