The US ended the $7,500 EV credit and replaced it with a loan-interest deduction. The UK is introducing a 3p-per-mile EV road tax. Meanwhile, home charging raises its own questions about panels, fuses, and real charging speed. These free calculators answer all of it, with the sources to prove it.

In late 2025, both countries rewrote the money side of EV ownership at the same time. In the US, the One Big Beautiful Bill Act ended the federal purchase credits for vehicles acquired after 30 September 2025. It introduced a deduction for interest on loans for US-assembled vehicles instead. In the UK, the Autumn Budget confirmed a new mileage-based charge called electric Vehicle Excise Duty (eVED) from April 2028. It also changed the Expensive Car Supplement and the Electric Car Grant.
Most of the information published about these changes is either out of date, buried in consultation documents, or written by companies trying to sell you a car. These calculators do the arithmetic transparently, state their assumptions, and link to the primary sources, IRS guidance and GOV.UK, so you can verify every number.
