The RV mileage budget calculator calculates total trip fuel cost, maintenance allocation, and cost per mile for your RV road trip. Include metric/imperial support for international travel planning.

How to Use the RV Mileage Budget Calculator
The RV mileage budget calculator creates a clear picture of driving-related trip costs for any RV road trip. Use it before booking campgrounds to ensure your total budget is realistic.
Step 1: Use real MPG from your last trip
Manufacturer MPG estimates for RVs are optimistic. Track your actual fuel usage over 2–3 fills to get a realistic number. Class A gas motorhomes often get 7–8 MPG in mountains versus 10–11 MPG on flat highways. Use the lower number for conservative budgeting.
Step 2: Budget maintenance even if nothing breaks
RV tires alone cost $1,000–3,000 every 40,000–60,000 miles. Adding $0.15/mile to a dedicated maintenance fund means you're never blindsided. The maintenance reserve accumulates even when nothing breaks, building a cushion for the inevitable expensive repair.
Step 3: Add campsite and living costs for total trip budget
The mileage calculator shows driving-specific costs. For a complete trip budget, add campsite fees ($30–75/night), food ($50–100/day for two people), activities, tolls, and any ferry or park entrance fees. Most RVers spend $150–250/day total (all-in) on the road, excluding loan payments and storage.
FAQ
Is this RV mileage calculator free?
Yes, completely free. All calculations run locally with no data transmitted.
How do I measure my RV in metric units?
Use the unit toggle to switch between imperial (miles/gallons/MPG) and metric (km/liters/L/100km). The calculator handles both systems.
What is a realistic RV MPG?
Class A gas motorhomes get 7–10 MPG. Class A diesel (pusher) get 9–13 MPG. Class C get 12–16 MPG. Class B vans get 18–25 MPG. Fifth wheels and travel trailers reduce tow vehicle fuel economy by 25–40% — a truck getting 20 MPG might get 12–14 MPG towing.
How much should I budget for RV maintenance per mile?
A conservative maintenance reserve is $0.10–0.20 per mile for a motorhome (tires, brakes, oil, seals). Travel trailers cost $0.05–0.10 per mile for maintenance. Major events (new tires, water heater, roof seal) cost $1,000–5,000 every few years. Saving $0.15/mile creates a fund for these inevitable expenses.
How do gas prices affect RV trip budgets?
Fuel is typically 40–60% of total RV trip variable costs (excluding campground fees). A 10% increase in gas price increases trip cost by 4–6%. For a 3,000-mile trip in a Class A getting 9 MPG, a $1 per gallon increase adds $333 to the trip cost. Always budget with current fuel prices plus a 10–15% buffer.
Should I include campsite fees in mileage calculations?
For a pure per-mile cost analysis, fuel and maintenance are appropriate. For total trip budgeting, add campsite fees, food, activities, and vehicle insurance. The mileage calculator gives the driving-specific costs; add overnight and incidental costs separately for a complete budget.
