What the defaults total
A 1,500-mile road trip at 28 mpg, $3.50 a gallon, three hotel nights and $50 a day for food comes to $767.50.
Fuel is the smallest of the big three at $187.50. Lodging at $360 and food at $200 together are three times the petrol bill, which is the usual shape of a road-trip budget.
How each line is built
Fuel = (distance ÷ mpg) × price per gallon. 1,500 ÷ 28 = 53.57 gallons × $3.50 = $187.50.
Lodging = nights × nightly rate. 3 × $120 = $360.
Food = days × daily spend. Three nights is four days on the road, so 4 × $50 = $200.
Tolls and fees are entered directly: $20.
Worked example
Fuel $187.50
Lodging $360.00
Food $200.00
Tolls $20.00
Total = $767.50
Why four food days for three nights
A trip with three overnight stays spans four calendar days: you eat on the departure day before the first night and on the arrival day after the last. Counting nights alone understates food by a quarter in this example.
The lines that are usually missing
- Wear. Tyres, oil and depreciation add roughly 10–15 cents a mile — $150–225 on this trip.
- Parking. City hotels commonly charge $20–40 a night.
- Activities. Entrance fees and tours are often the largest discretionary line.
- Snacks and coffee. Rarely in the food figure and reliably present on a long drive.
Making the number useful
Fuel is the line you can actually change: five more mpg on this trip saves about $33, while one fewer hotel night saves $120. When the budget is tight, the fix is almost never the driving.
Frequently Asked Questions
Why is fuel only $187.50 on a 1,500-mile trip?
Because 1,500 ÷ 28 mpg is 53.6 gallons, and at $3.50 a gallon that is $187.50. Fuel is usually a smaller share than people expect.
Why four days of food for three nights?
Three overnight stays span four calendar days — departure day through arrival day. Counting nights alone would understate food spending.
What does the total leave out?
Vehicle wear at roughly 10–15 cents a mile, parking, activities and snacks. On this trip wear alone adds about $150–225.
How much does better fuel economy save?
At 33 mpg the same 1,500 miles uses 45.5 gallons instead of 53.6, saving about $28 at $3.50 a gallon — modest next to a single hotel night.
Should I include rental car costs?
Yes, if you are renting — add the daily rate and any one-way fee to the fixed costs. They do not scale with distance, so they belong outside the fuel line.
How do I split the cost between passengers?
Divide the total — not just the fuel. On this $767.50 trip split four ways each person pays about $192, and that includes lodging and food. Splitting only the $187.50 of petrol understates each share by a factor of four.
How much is one night of the trip?
About $300 across the four food days: $120 of lodging plus $50 of food, plus a share of the $207.50 of fuel and tolls. That per-day figure is the one to compare when deciding whether to add a night.
