How do I calculate commuting cost?

Multiply the round-trip distance by fuel cost per mile, add parking, then multiply by commuting days. Include 48 working weeks (allowing 4 weeks holiday) for annual totals.

Is commuting by car cheaper than the train?

It depends on the route. For short commutes, driving is often cheaper. For longer commutes into cities, trains may be cheaper when you factor in parking and congestion charges. Car sharing can halve fuel costs.

Can I claim commuting costs on tax?

Regular commuting to a permanent workplace is not tax-deductible. However, travel to temporary workplaces or client sites may qualify for HMRC mileage allowance at 45p/mile (first 10,000 miles).

Is it cheaper to drive or take the train to work?

For short commutes (under 15 miles), driving is usually cheaper. For longer commutes (30+ miles), train season tickets can be competitive when you factor in parking, fuel, and car wear. The break-even point depends on your specific route and fuel economy.

How can I reduce my commuting costs?

Consider car sharing with colleagues to split fuel costs. Working from home 1-2 days per week cuts costs by 20-40%. Switching to a more fuel-efficient car or EV can significantly reduce fuel bills. Cycling for shorter commutes is essentially free. Many employers offer Cycle to Work schemes.
