Fuel & transport

Trip cost, not just liters

Fuel spend depends on distance, how efficiently your vehicle uses fuel, and the pump price in your area. The calculator turns those three inputs into liters, total trip cost, and cost per kilometer — handy for commuting and long drives alike.

Presets for common routes and vehicle types are shortcuts; override distance and efficiency when you know your actual odometer readings.

For a better real-world estimate, track at least two full tanks: record odometer distance, liters filled, and route type. City traffic in Metro Manila, mountain roads, heavy loads, and long idle time can move actual km/L far away from brochure figures. Your own fill-up log is usually more useful than a generic vehicle rating.

Limits of a static estimate

Traffic, idling, load, and driving style change real-world consumption. Use results for budgeting bands, then track your own fill-ups for precision.

Pump prices also move frequently. If you are costing a long trip, check the latest station price or DOE Oil Monitor first, then run low, expected, and high price scenarios. The spread tells you how much buffer to bring for toll detours, traffic, weather, or route changes.

For regular commuters, calculate cost per kilometer and cost per workday rather than only one trip total. That makes it easier to compare driving, carpooling, motorcycle use, public transport, or occasional work-from-home days using the same baseline.

Practical examples for commuters

A 30 km round-trip commute at 12 km/L uses about 2.5 liters per day. At ₱65 per liter, that is roughly ₱162.50 per workday before parking and tolls. Over 22 workdays, fuel alone is about ₱3,575. Small changes in route or driving style can therefore matter more than they look on a single day.

A provincial road trip behaves differently. Highway speeds may improve efficiency, but passengers, luggage, AC use, climbs, and traffic near town centers can reduce it. Build a buffer instead of planning with the best possible km/L.
