Recorded in the app on an earlier build · priced at its then-default $3.20/gal
Mileage apps tell you the miles for your taxes.
LiveGasCost shows what the drive is costing you — in dollars, while you drive.
Live cost
The dollars climb while the engine runs. No waiting for a monthly report.
Idle cost
Sitting still burns fuel too. It is counted on its own, so you can see it.
- $4.12 East Coast (PADD 1)
- $4.15 Midwest (PADD 2)
- $3.85 Gulf Coast (PADD 3)
- $4.44 Rocky Mountain (PADD 4)
- $5.64 West Coast (PADD 5)
Fuel prices are EIA US regular average — $4.33/gal for the week of Oct 12, 2026 — and the five regional figures above are the EIA's own weekly series for the same week. The worked example further down is priced at EIA Midwest (PADD 2) regular average, $4.15/gal, because it is a Madison drive. All of it is refreshed weekly from the EIA's own series. Distances come from real roads on our own routing server, not straight lines. MPG comes from the EPA's published ratings for the exact car you drive.
Your cost, right on the dash
Mount it, start driving, and watch every mile add up in real time — the whole trip, right where you can see it.
How it works
Three steps, and you only do the first one.
Step 1: Install it
Download the app and pick your car from the EPA database. That is the setup — no account, no sign-up, no email required.
Step 2: Drive
On Android, turn on automatic detection and the app notices your drives on its own, or hit Start trip. On iPhone, hit Start trip when you leave and Stop when you arrive. Either way, your drives stay on the phone unless you sign in to the web dashboard.
Step 3: See what it cost
Watch the dollars climb live as you drive, and find every trip waiting in your history afterwards — priced from real roads, your car's real MPG and this week's real fuel price.
For drivers
Everything your fuel budget needs, and nothing that needs an account.
Real-time tracking
Start a trip and watch the cost tick up live — GPS distance, your vehicle's EPA MPG (or, on Full, the MPG learned from your fill-ups), and your region's weekly gas price, priced per mile as you drive.
Multi-vehicle garage
Save every vehicle you drive — commuter, truck, diesel — and switch with one tap. Each keeps its own MPG and fuel type.
Manual price override
Filled up at a price the averages don't know about? Set your exact price per gallon and every calculation uses it until you clear it.
Install it. Drive. See the cost.
Six screens from the real app — one trip, start to finish: priced live, mapped, logged, and planned before you leave.
Live cost tracking
Watch the dollar figure climb as you drive. Shot on an earlier build, before a vehicle was added — the app priced it at its then-default 33 MPG and $3.20/gal.
Mapped trip detail
Snapped route, addresses, and full stats. A real drive from Aug 15, 2026, priced at that week's gas — $3.81/gal Midwest regular.
Every trip, logged
Your drive history with cost and MPG. Real drives from Aug 2026, each priced at the gas that week.
Type a place, not a coordinate
Search by name. The addresses come from our own server.
Know the cost before you go
Real roads, real distance. This shot was taken before a vehicle was added, so the app priced it at its placeholder 25 MPG and $3.20/gal — add your vehicle and both become yours.
Total, or stop by stop
$2.55 the first leg, $3.61 the second — and they add up. Same 25 MPG and $3.20/gal the screen above was shot with.
What a real trip looks like
Example trip · 2020 Honda Civic
148 mi ÷ 32 MPG = 4.625 gal × $4.145 = $19.17 — the same math the app runs live, every mile.
Fuel price: EIA Midwest (PADD 2) regular average, week of Oct 12, 2026 — a Madison drive, priced at its own region rather than at the national average above.
Questions, answered
How accurate is the MPG?
Vehicle MPG comes from the official EPA fuel-economy database — 24,685 vehicles back to 1984. Heavy-duty trucks the EPA doesn't rate (192 of them, mostly 2500/3500 pickups) use clearly-labeled real-world estimates, and you can always enter your own number if you know your true average.
Can I track multiple vehicles?
Yes. Save each vehicle to your garage with its own year, make, model, fuel type, and MPG, then switch between them with one tap on the Track screen. Diesel vehicles automatically use diesel prices.
Are the gas prices real-time?
Prices are official EIA regional averages, updated weekly — that is how often the EIA publishes them. You can override with your exact pump price anytime.
Does it work offline?
Trip tracking does — GPS needs no connection, and a manual price override keeps cost math running without signal. Live price lookups resume when you're back online; nothing is lost in between.
Where does my data go?
Your drives stay on your phone unless you sign in to the web dashboard. Your drives, routes and history live in the app, and you need no account to drive. If you sign in to the web dashboard at livegascost.com, a copy of each drive goes to your account so you can see it there. The app still goes online for things like maps, fuel prices, place search, app updates and crash reports. We never track you across apps, and we never sell your data.
What vehicles does it support?
Any car, truck, or diesel in the EPA database (24,685 vehicles back to 1984), plus manual entry if yours isn't listed or you want to use your own MPG.
