How the Estimator Works
The Trip Fuel Cost Estimator combines your vehicle specifications with real-time fuel prices from OilPriceAPI to calculate accurate trip costs. Rather than relying on guessed or outdated prices, this tool uses live market data updated throughout the day.
Calculation Method
Fuel Needed = Trip Distance / Vehicle MPG
Trip Cost = Fuel Needed × Current Fuel Price
Cost Per Mile = Current Fuel Price / Vehicle MPG
Real-Time Pricing from OilPriceAPI
This estimator retrieves current fuel prices through our reliable API infrastructure. The same pricing data is trusted by logistics companies, travel apps, and financial services platforms.

Road Trip Planning Use Cases
Vacation Budget Planning
Before booking accommodations and activities, know exactly how much fuel will cost for your road trip. Accurate fuel estimates help you allocate budget across all travel expenses.
Business Travel Reimbursement
Calculate precise fuel costs for business trips to submit accurate expense reports. Many companies require current fuel price documentation for mileage reimbursement.
Delivery and Service Routes
Service professionals and delivery drivers can estimate daily fuel costs based on planned routes. Helps with pricing services and managing operational costs.
Moving and Relocation
Planning a long-distance move with a rental truck? Estimate fuel costs for the journey to include in your moving budget, especially important for one-way rentals with different MPG ratings.

JavaScript Implementation
async function estimateTripCost(distanceMiles, vehicleMpg, fuelType = 'GASOLINE_US') {
const response = await fetch(
`https://api.oilpriceapi.com/v1/prices/latest?by_code=${fuelType}`,
{ headers: { 'Authorization': `Token ${process.env.OILPRICE_API_KEY}` } }
);
const { data } = await response.json();
const fuelPrice = data.prices[0].price;
const gallonsNeeded = distanceMiles / vehicleMpg;
return {
gallonsNeeded: gallonsNeeded.toFixed(2),
oneWayCost: (gallonsNeeded * fuelPrice).toFixed(2),
roundTripCost: (gallonsNeeded * fuelPrice * 2).toFixed(2),
costPerMile: (fuelPrice / vehicleMpg).toFixed(3),
fuelPrice: fuelPrice
};
}
// Example: 500-mile trip, 28 MPG vehicle
estimateTripCost(500, 28).then(result => {
console.log(`Trip will cost approximately $${result.oneWayCost}`);
});
Python Implementation
import requests
import os
def estimate_trip_cost(distance_miles, vehicle_mpg, fuel_type='GASOLINE_US'):
response = requests.get(
'https://api.oilpriceapi.com/v1/prices/latest',
params={'by_code': fuel_type},
headers={'Authorization': f'Token {os.environ["OILPRICE_API_KEY"]}'}
)
fuel_price = response.json()['data']['prices'][0]['price']
gallons_needed = distance_miles / vehicle_mpg
return {
'gallons_needed': round(gallons_needed, 2),
'one_way_cost': round(gallons_needed * fuel_price, 2),
'round_trip_cost': round(gallons_needed * fuel_price * 2, 2),
'cost_per_mile': round(fuel_price / vehicle_mpg, 3),
'fuel_price': fuel_price
}
# Example: 1,200-mile cross-country trip
result = estimate_trip_cost(1200, 25)
print(f"Estimated fuel cost: ${result['one_way_cost']}")
Tips for Accurate Trip Cost Estimation
Account for Driving Conditions
Highway driving typically yields better MPG than city driving. For mixed-route trips, consider using a weighted average of your vehicle's city and highway ratings.
Factor in Terrain
Mountain driving and hilly terrain significantly reduce fuel efficiency. Add 10-20% to your estimate for mountainous routes.
Consider Weather Impact
Cold weather, strong headwinds, and air conditioning use all reduce fuel efficiency. Adjust estimates accordingly for extreme conditions.
Check Historical Trends
Use OilPriceAPI's historical data endpoint to see if prices tend to rise or fall during your planned travel dates.
Frequently Asked Questions
How accurate are these estimates? Estimates are based on current fuel prices and your input values. Actual costs may vary based on driving conditions, traffic, and local price variations.
Can I estimate costs for rental vehicles? Yes. Use the rental vehicle's published MPG rating (available on the rental company's website) with current fuel prices.
Does this account for price differences along my route? The calculator uses national average pricing. Regional variations may result in slightly higher or lower actual costs.
