How do I pick a realistic fuel price?

Use a route-based gas price tool for your area and planned route, then paste that fuel price into this estimator for a more realistic budget.

How accurate is this estimator?

It is a planning estimate based on your inputs. Real costs change due to fuel price swings, wind, elevation, detours, speed, and towing weight.

Which fuel economy unit should I use?

Use the unit you know. This tool supports MPG, km/L, and L/100km.

1) Trip basics

Estimated distance Distance unit Trip type Vehicle setup

This applies a conservative adjustment to fuel economy because towing, wind, and terrain usually reduce efficiency.

2) Fuel inputs

Currency

This tool does not convert currencies. It simply uses your symbol to keep the budget readable.

Fuel price Fuel price unit Fuel economy Fuel economy unit

If you want a safer estimate, enter a slightly worse fuel economy than your best day on flat ground.

3) Camping and food

Campground fees

Campground cost (per night)

Number of nights

Food and groceries

Food budget (per day)

Number of days

If you are unsure about days, a simple rule is days = nights + 1. It is not perfect, but it stops the under-budget problem.

4) Extras and results

Additional costs

This is a planning estimate. Real-world costs can change due to fuel price swings, headwinds, elevation, detours, speed, and towing weight.

Final thoughts

RV travel is about freedom, but budgeting is what keeps that freedom fun. Run a few scenarios before you go. Small changes like fewer miles, one less paid night, or better grocery planning can make a surprising difference.
