Notes on IoW running costs
Isle of Wight petrol and diesel prices are typically 8–15p/litre higher than the UK mainland average due to island logistics and supply chain costs. This calculator uses IoW-specific fuel prices for more accurate estimates than a UK-average tool would give.
Insurance figures use the IoW average of £449/year. Younger drivers (under 25) will pay significantly more; experienced drivers over 40 will often pay less. The figure is used as a baseline — the relative fuel cost comparison between car types is the most useful output of this tool.
Ferry costs for mainland travel are not included. If you cross to the mainland regularly, add those to your annual budget separately using our ferry cost calculator.
