Planning a road trip but not sure what it will cost? This calculator adds up fuel, lodging, food, and activities so you know your total trip budget — and exactly what each traveler should chip in. Works with miles or kilometers, MPG or L/100km, and any fuel price you enter.
Scenario: A 1,200-mile round trip in a car that gets 30 MPG with gas at $3.50/gallon. The trip lasts 3 days with 2 hotel nights at $120/night, $60/day for food, and $150 set aside for activities. Two travelers are splitting the cost.
| Distance | 1,200 miles |
| Fuel (1,200 ÷ 30 × $3.50) | $140.00 |
| Lodging (2 nights × $120) | $240.00 |
| Food (3 days × $60) | $180.00 |
| Activities & Misc | $150.00 |
| Total Trip Cost | $710.00 |
| Cost Per Person (÷ 2) | $355.00 |
Key takeaway: Fuel is often less than a third of the real trip cost — lodging and food usually dominate the budget.
Scenario: An 800 km drive in a car that uses 7.5 L/100km with diesel at €1.80/liter. Two days and one night, a €90/night hotel, €40/day for food, and €60 for activities. Two travelers split everything.
| Distance | 800 km |
| Fuel ((800 ÷ 100) × 7.5 × €1.80) | €108.00 |
| Lodging (1 night × €90) | €90.00 |
| Food (2 days × €40) | €80.00 |
| Activities & Misc | €60.00 |
| Total Trip Cost | €338.00 |
| Cost Per Person (÷ 2) | €169.00 |
Key takeaway: In metric mode, the calculator switches to liters and price-per-liter automatically — just pick Kilometers in the unit dropdown.
Scenario: A 400-mile weekend trip in a 32 MPG car with gas at $3.40/gallon. Two days, zero hotel nights (staying with family), $50/day for food, and $40 for activities. One traveler pays for everything.
| Distance | 400 miles |
| Fuel (400 ÷ 32 × $3.40) | $42.50 |
| Lodging (0 nights) | $0.00 |
| Food (2 days × $50) | $100.00 |
| Activities & Misc | $40.00 |
| Total Trip Cost | $182.50 |
| Cost Per Person | $182.50 |
Key takeaway: Skipping lodging is the single biggest way to slash a short trip's cost — leave nights at 0 to see the difference.
A good road trip budget starts with realistic per-day numbers. The American Automobile Association (AAA) publishes widely cited benchmarks: expect to pay roughly $150-200 per night for mid-range lodging and $60-80 per person per day for food when you eat most meals at restaurants. Fuel is the most variable line item — it depends entirely on your vehicle's efficiency and the price of gas where you're driving, which is why this calculator separates it out and lets you plug in your own MPG and price.
Once you have those four numbers (fuel, lodging, food, activities), the smartest habit is to add a 15-20% buffer on top of the total. Travel researchers consistently find that unplanned expenses — an extra night when the weather turns, a toll you didn't expect, a must-see museum — push real spending 15-20% above the original plan. Budgeting that cushion in advance means the trip stays fun instead of stressful.
Finally, decide how you'll split costs before you leave. The cleanest approach for groups is one shared fund for fuel, lodging, and groceries, with each person covering their own meals and souvenirs. Our per-person result gives you the exact number to collect from each traveler for the shared costs.
Most trip budgets cover gas and hotels, then get blindsided by the smaller costs that quietly add up. Here are the ones travelers miss most often:
Add these to the "Activities & Misc" field in the calculator so your total reflects the true cost of the road, not just the bill at the pump.
Road trips are one of the easiest vacations to make cheaper without ruining the fun. Start with the biggest line items — lodging and food — and work down from there:
Run the calculator with a few different scenarios — fewer nights, cheaper hotels, more travelers splitting costs — and you'll quickly see which lever saves you the most.
