Road calculateur de coût de voyage

The LA → Grand Canyon → Las Vegas loop (1,030 mi across CA · AZ · NV) in an SUV at 24 mpg costs about $210 of gas — 42.9 gallons at the route's state average of $4.90/gal ($5.80 / $4.18 / $4.71, California the expensive one). Tolls are zero on this loop, two modest hotel nights ($110/night) add $220, so the grand total is $430 — $215 per person for a party of two, over roughly 2.3 driving days. Nine more preset routes (NYC→DC with $40 of tolls, Chicago→Niagara at $45) recompute instantly in the tool below.

FAQ

How much gas money do I need from LA to Vegas?

Straight up I-15 it's about 270 miles each way: roughly $45–50 of gas one-way in an SUV (24 mpg) or about $35 in a compact at 2026 prices — call it $70–100 round trip. The fuller LA→Grand Canyon→Vegas loop preset here is 1,030 miles, ≈43 gallons and ≈$175 of gas in an SUV, blending $4.70 California, $3.55 Arizona and $4.00 Nevada pump prices. Fill up before leaving Nevada — California is the expensive side of that drive.

Are US tolls cash or E-ZPass?

Most East Coast corridors (NJ Turnpike, I-95 into DC) no longer take cash at all — cameras read your plate and the bill arrives by mail or through your rental company at a markup. An E-ZPass in the East, a SunPass in Florida or a FasTrak in California is usually the cheapest and fastest way through. Western routes like the LA→Grand Canyon→Vegas loop are toll-free to begin with.

What's the rental-car toll program trap?

Rental companies sell toll programs at $10–15 per day, billed every rental day even when you cross no tolls — a two-week rental can rack up $100–150 against $20–40 of actual tolls. Decline it and pay the plate invoices yourself, carry your own transponder, or route toll-free. Each route here shows its realistic toll estimate so you can compare it to the daily-fee price.

What are the cheapest days of the week to drive?

Fill up Monday or Tuesday: pump prices tend to rise into Thursday–Friday weekend demand and ease early the next week — a weekly swing of 10–25¢/gal, which is real money on a 40-gallon trip. Hotels follow the same rhythm: Sunday–Thursday nights run cheaper than Friday–Saturday. And avoid Memorial Day, July 4th and Labor Day weekends, when gas and roadside rates spike together; shifting a trip by a day or two usually saves more than hunting for the cheapest station.

How much do gas prices differ between states?

The 2026 national average sits near $2.90–3.00/gal, but classic road-trip states run above it — state taxes and fuel blends swing the pump from about $4.70 in California and $4.30 in Washington down to roughly $3.20 in Texas and $3.30 in Ohio. Practical rule: fill the tank before leaving the cheap states. The calculator blends each route’s state prices — the LA→Grand Canyon→Vegas loop averages out near $4.10/gal.

Should we drive or fly for this trip?

Rule of thumb: driving wins with 2 or more people under ~500 miles one-way. NYC→DC costs about $75 in gas and tolls for the entire car versus $150–250 per person by air before bag fees — compare the per-person total from this tool against a typical fare before you book. Cross-country (LA→NYC), flying wins practically every time. And remember the car is your transportation for the whole trip, not just the intercity leg.

Are national park entry fees included?

No — park entry is not in the totals. Most major parks (Grand Canyon, Zion, Yosemite) charge $35 per vehicle for a 7-day pass, and the $80 annual America the Beautiful pass pays for itself from the third paid park onward. Routes like Vegas→Zion or the Grand Canyon loop need that pass added on top of the grand total shown here.

Does this work for an electric car (EV)?

Not directly — the math here is gallons × each state’s price per gallon. An EV needs kWh per mile × charging price: 2026 DC fast charging at $0.35–0.55/kWh behaves like gas under ~$2/gal, though charging stops eat into your daily mileage. Treat the gasoline figure as an upper bound — road-trip charging typically runs 40–60% cheaper.
