A road trip has more variable costs than a package holiday, but they're easy to estimate. This guide gives a formula for fuel, typical tolls and vignettes, price ranges for accommodation and food, the costs people forget, and two worked 14-day budgets for two people: roughly 2,300 EUR on a budget and 3,900 EUR mid-range.
Fuel Costs: Your Biggest Variable Expense
Fuel will typically be your single largest daily expense after accommodation. The total cost depends on three factors: how far you drive, your vehicle's fuel efficiency, and local fuel prices.
How to Estimate Your Fuel Budget
Use this simple formula:
(Total distance in km / 100) x litres per 100km x price per litre = total fuel cost
For example, a 3,000km trip in a car that uses 7L/100km with fuel at 1.70 EUR per litre: (3000 / 100) x 7 x 1.70 = 357 EUR.
Fuel Prices by Region (rough guide; check before you go)
- USA: $3.20-4.50 per gallon (varies hugely by state)
- Western Europe: 1.55-2.10 EUR per litre
- Eastern Europe: 1.25-1.65 EUR per litre
- UK: roughly 1.30-1.55 GBP per litre
- Australia: 1.70-2.20 AUD per litre
Fuel-Saving Tips
- Keep your speed steady. Cruise control on flat motorways helps, and dropping from 130 to 110 km/h saves more.
- Avoid filling up at motorway service stations, where prices are typically 10-20% higher. Exit and find a supermarket or town station instead.
- Keep tyres properly inflated. Under-inflated tyres increase fuel consumption measurably.
- Remove roof boxes when not in use. The aerodynamic drag adds roughly 10-15% to fuel consumption at motorway speeds.
- Use fuel price apps like GasBuddy (USA), Waze or national apps to find cheaper stations. Our guide to fuelling up in Europe covers pump names and payment.
Fill up before crossing borders, especially from cheaper countries into more expensive ones. The difference between Luxembourg and France is often 20 cents a litre or more.
Toll Roads and Vignettes
Tolls catch out a lot of first-time road trippers in Europe, and in some countries avoiding them adds hours. Our toll systems guide has more detail.
Toll Costs by Country
- France: One of the most expensive toll networks in Europe. Paris to Nice costs approximately 85-90 EUR one way. Paris to Bordeaux around 55-65 EUR.
- Italy: Milan to Rome approximately 45-55 EUR. The Italian autostrada system charges by distance.
- Spain: Many motorways have become free since 2018, including the AP-7 from Barcelona to Valencia, but some stretches still charge.
- Portugal: Lisbon to Faro approximately 22-28 EUR. Electronic tolling (Via Verde) requires registration.
- USA: Varies by state; some have many toll roads, others very few.
Vignette Systems
Several countries use a vignette (sticker or electronic tag) instead of per-distance tolls:
- Austria: 10-day vignette approximately 12-13 EUR
- Switzerland: Annual vignette 40 CHF (no shorter option available)
- Czech Republic: 10-day e-vignette approximately 13 EUR
- Slovenia: 7-day vignette approximately 16 EUR
Buy vignettes at border petrol stations or online before arrival. Driving on a vignette road without one brings fines of 100 EUR or more.
Accommodation Budgeting
Accommodation is where you have the most control. The gap between camping and a comfortable hotel is large, and mixing types works well (our accommodation guide compares them).
Accommodation Cost Tiers
- Wild camping / free camping: 0 EUR per night. Legal in Scandinavia, Scotland, and parts of Eastern Europe. Illegal or restricted in most of Western Europe.
- Campsites: 10-35 EUR per night for a pitch. Add 5-10 EUR for electric hookup.
- Hostels: 15-40 EUR per person per night for a dorm bed. Private rooms in hostels run 40-80 EUR.
- Budget hotels: 50-90 EUR per room per night.
- Mid-range hotels: 80-160 EUR per room per night.
- Airbnb / self-catering apartments: 50-130 EUR per night, but the ability to cook can save you 30-50 EUR per day on food.
Money-Saving Accommodation Strategies
- Mix it up: Alternate one night camping with one night in a hotel. You save money and still get regular access to a proper shower and bed.
- Book apartments with kitchens: Self-catering for breakfast and lunch, then eating out for dinner only, cuts your food budget a lot.
- Travel in shoulder season: Prices in May-June and September-October can be 30-50% lower than July-August.
- Stay outside city centres: A hotel 15-20 minutes' drive from the centre is often half the price, and you have a car anyway.
- Use loyalty programs: If you prefer chains, programs like IHG, Marriott Bonvoy, or Accor Live Limitless can accumulate points quickly during a multi-week trip.
For European road trips, the France Passion scheme (and similar programs in other countries) lets you stay overnight for free at vineyards, farms, and artisan producers. You are expected to buy something, but a bottle of wine is a lot cheaper than a hotel room.
Food and Drink Budget
Food costs on a road trip depend almost entirely on how you choose to eat. The difference between self-catering and eating out three times a day can be 50-80 EUR per person per day.
Daily Food Budget Estimates (Per Person)
- Self-catering only: 15-25 EUR per day. Shop at supermarkets and local markets, prepare all meals yourself.
- Mixed (self-catering + one meal out): 30-50 EUR per day. Make breakfast and lunch, eat out for dinner.
- Eating out for most meals: 50-90 EUR per day in Western Europe, 25-50 EUR in Eastern and Southern Europe.
Food-Saving Strategies
- Always eat breakfast at your accommodation or from supplies in the car. Hotel breakfasts are often overpriced, and cafe breakfasts add up fast.
- Buy lunch supplies from supermarkets and have picnics. It's cheaper, and a baguette, cheese and fruit at a viewpoint beats most motorway lunches.
- When eating out, choose lunch menus. Many European restaurants offer a fixed-price lunch menu (menu del dia in Spain, formule in France) that is significantly cheaper than dinner.
- Carry a cooler bag with ice packs to keep perishables fresh between stops.
- Fill water bottles from taps. Tap water is safe to drink in almost all of Western and Central Europe.
Hidden and Overlooked Costs
These are the expenses that do not make it into most budgets but add up over the course of a trip.
Parking
City centre parking in European cities is expensive. Expect to pay 15-40 EUR per day in major cities like Paris, Amsterdam, or Rome. Even smaller cities often charge 5-15 EUR per day. Many hotels charge separately for parking, typically 10-25 EUR per night.
Strategy: Use park-and-ride facilities on city outskirts and take public transport into the centre. This can save 20-30 EUR per day compared to city centre parking.
Mobile Data and Roaming
If you are travelling internationally, check your mobile plan. EU roaming is free for EU residents, but UK, US, Australian and other non-EU travellers may pay daily charges (see our mobile data guide). A local SIM card or an eSIM (from providers like Airalo or Holafly) typically costs 10-30 EUR for 10-30 days of data.
Attractions and Activities
Entry fees add up quickly. A family of four visiting a major museum, a castle, and a national park in a single day could spend 60-100 EUR. Budget 10-20 EUR per person per day for activities, then adjust based on your plans.
Laundry
On trips longer than a week, you will need to wash clothes. Launderettes cost 5-10 EUR per load. Some accommodation has free or cheap laundry facilities, so factor this into your accommodation choice.
Car Rental Extras
If renting, watch for: additional driver fees (5-15 EUR per day), GPS rental (10-15 EUR per day, use your phone instead), child seat rental (5-15 EUR per day, consider bringing your own), and young driver surcharges for those under 25.
Add a 15-20% contingency buffer to your total budget. Something always comes up: a parking ticket, a repair, an unplanned activity or a pricier meal than expected.

Frequently asked questions
How much should I budget per day for a road trip?
In Western Europe, two people sharing a car should allow roughly 150-200 EUR a day on a budget, 250-300 EUR mid-range and 400 EUR or more for a comfortable trip, including fuel, tolls, accommodation, food and activities (see the sample budgets above). Eastern Europe is cheaper. The biggest variable is accommodation: camping versus hotels can change your daily spend by 50-100 EUR.
Are road trips cheaper than flying and booking hotels?
For two or more people travelling together, road trips are almost always cheaper than the equivalent trip by air with car rental at each destination. The savings increase with group size since you split fuel and accommodation costs. Solo travellers may find that flights and public transport are more economical, depending on the route.
How can I track my spending during the trip?
Use a simple spreadsheet or a travel budgeting app like Trail Wallet, TravelSpend, or Splitwise (the latter is excellent for splitting costs between travel companions). Record expenses each evening rather than trying to remember at the end of the trip. Daily tracking tends to keep spending in check.
