With one person paying, the cost per person is 32; the fuel cost per mile is approximately 0.1333 currency units.<\/p>\n<p>\n\r\n<\/section>\n<h2>How to use the calculator<\/h2>\n<ol>\n<li>Set <strong>Tab<\/strong> to Trip for a single journey or Commute for a recurring weekly journey.<\/li>\n<li>For Trip, enter <strong>Trip distance<\/strong> and select its <strong>Distance unit<\/strong>. Enter the one-way distance even if you plan to return, then choose One way or Round trip under <strong>Trip type<\/strong>.<\/li>\n<li>For Commute, enter <strong>One-way commute distance<\/strong>, select its <strong>Distance unit<\/strong>, and enter <strong>Commute days per week<\/strong>. The calculator assumes you travel to and from your destination on each of those days.<\/li>\n<li>Enter your vehicle\u2019s <strong>Fuel economy<\/strong> and choose the matching <strong>Fuel economy unit<\/strong>: MPG (US), MPG (UK), L\/100 km, or km\/L. Use a figure representative of the driving you expect.<\/li>\n<li>Enter <strong>Fuel price<\/strong> and choose whether the <strong>Price unit<\/strong> is per US gallon or per liter. Enter a number without a currency symbol.<\/li>\n<li>For Trip, set <strong>People splitting trip cost<\/strong> if the fuel expense will be shared equally. Read the fuel-needed and cost results for your selected tab.<\/li>\n<\/ol>\n<h2>What the fuel cost estimate means<\/h2>\n<p>Fuel cost depends on how far you drive, how much fuel the vehicle uses over that distance, and the price of that fuel. The calculator reports fuel needed in both liters and US gallons, regardless of which units you entered. It then uses your selected price unit to calculate cost. A fuel price of 4 per US gallon is not treated as 4 per liter.<\/p>\n<p>In Trip mode, <strong>Total trip cost<\/strong> covers the entire selected journey: one way or round trip. <strong>Cost per person<\/strong> divides that fuel cost equally by the number of people entered. <strong>Trip cost per mile<\/strong> and <strong>Trip cost per kilometer<\/strong> divide the total fuel cost by the total distance driven, not just the one-way distance. These figures can help compare routes of different lengths, although they do not include tolls, parking, or vehicle wear.<\/p>\n<p>In Commute mode, fuel needed and <strong>Weekly commute cost<\/strong> cover all entered commute days in one week. <strong>Average monthly commute cost<\/strong> is the weekly cost multiplied by 52 and divided by 12; <strong>Yearly commute cost<\/strong> is the weekly cost multiplied by 52. These are annualized estimates, not predictions for a particular calendar month. For example, a 15-mile one-way commute on five days a week totals 150 miles weekly. At 30 MPG (US) and 4 per US gallon, that is 5 US gallons and 20 currency units per week, or about 86.67 per average month.<\/p>\n<h2>Assumptions and practical tips<\/h2>\n<p><strong>Match the fuel economy unit to your source.<\/strong> MPG (US) and MPG (UK) use different gallon sizes and produce different fuel estimates for the same number. L\/100 km measures fuel consumed per distance, so a lower value means better economy; with MPG or km\/L, a higher value means better economy. If you have recent fill-up and distance records, the <a href=\"https:\/\/wpcalc.com\/en\/life\/gas-mileage-calculator\/\">Gas Mileage Calculator<\/a> can help you estimate a more representative figure.<\/p>\n<p>The estimate assumes constant fuel economy and fuel price throughout the journey. Traffic, hills, speed, weather, vehicle load, and idling can change actual consumption. For a long drive, consider planning refueling with the <a href=\"https:\/\/wpcalc.com\/en\/life\/road-trip-fuel-stops-calculator\/\">Road Trip Fuel Stops Calculator<\/a>. To account for expenses beyond fuel, use the <a href=\"https:\/\/wpcalc.com\/en\/life\/travel-budget-calculator\/\">Travel Budget Calculator<\/a>.<\/p>\n<p>Commute calculations assume the same round-trip distance on every entered day for 52 weeks. Adjust the number of days or use a shorter planning period if you expect holidays, remote-work days, or a changing schedule.
