What the numbers say
The Kia EV6 costs about £46,944 to own over 5 years in the UK — £782/month, £0.78/mi at 12,000 mi/yr — and depreciation is the biggest line: £28,263, 60% of the total (as of August 6, 2026).
- This one isn't close: the Kia EV6 undercuts the Mercedes-Benz GLC 220d 4Matic AMG Line by £4,844 — about 9% of the Mercedes-Benz GLC 220d 4Matic AMG Line's 5-year total.
- At any realistic annual distance the Kia EV6 is already the cheaper car to own — more driving only widens its lead.
- Where the Kia EV6's £46,944 actually goes: depreciation £28,263 (60%), financing interest £8,009 (17%), charging £5,392 (11%), insurance £2,780 (6%), maintenance £1,500 (3%), registration & fees £1,000 (2%).
- Per mile, that is £0.47 of depreciation and £0.09 of charging, with £0.22 for everything else — £0.78/mile all-in.
- Charging vs the fleet: at £5,392 over 5 years the Kia EV6 sits within £278 of the £5,670 median for the 27 EVs we price — nothing unusual either way.
What we assume for maintenance
Assumed £300/yr for an EV at 12,000 mi/yr — about £1,500 of the 5-year total above. On this market's assumptions an EV runs about £150/yr less in maintenance than a petrol car (£300 vs £450). See the methodology for sources; adjustable in the calculator.
