Choosing between the Citroen C5 and Fiat 500 isn't just about purchase price — the true cost of ownership tells a different story. Using our cost model and UK market averages, we can show exactly what each car costs to run every year.

Annual Running Cost Overview

Insurance Costs

Insurance is one of the biggest variables in running costs. Based on our data, the Fiat 500 comes out cheaper to insure, with an average premium of £419 per year compared to £570 — a difference of £151 annually. Insurance is calculated using standardised driver demographics (age 35, 3 years no claims) so the difference reflects the vehicle itself rather than driver risk.

Fuel & Energy Costs

The Fiat 500 has the lower annual fuel cost at £1,260 per year, saving £450 over the Citroen C5. Fuel costs are calculated from real-world mileage data taken from DVSA MOT odometer records, using current UK pump prices per mile for each fuel type.

Depreciation

The Fiat 500 holds its value better, with estimated annual depreciation of £2,340 versus £2,700 for the Citroen C5. Depreciation is typically the largest single running cost — often larger than fuel — making this a significant factor in the true cost of ownership.
