A full tank in a Honda Accord is about 14.8 gallons (56 liters) of gasoline.
For the current ninth-generation Accord (2018 to present), the official fuel tank capacity is 14.8 gallons. The actual price to fill a tank depends on your local gas price and how much fuel you start with when you begin filling. You may not fill exactly to the theoretical maximum due to how fueling and sensors operate, but 14.8 gallons represents the nominal capacity used by manufacturer specifications.
Official fuel tank capacity for the latest Honda Accord generations
The following reflects the standard capacity reported by Honda for recent Accord models. Use this as a baseline for planning and budgeting fuel costs.
- Fuel tank capacity: 14.8 gallons (56 liters) for 2018–present Honda Accord models (ninth generation, across most trims).
Note: The stated capacity is the nominal tank size. Actual fill volume may be slightly less, depending on the fill level before you start pumping and safety features that stop the flow at near-full.
Estimating the cost to fill a full tank
To estimate how much a full tank would cost, multiply the current price per gallon by the tank capacity. Use your local price per gallon for accuracy, and adjust for the amount of fuel you already have in the tank.
- Step 1: Find the current average price per gallon in your area (via apps, stations, or local listings).
- Step 2: Multiply that price by 14.8 gallons to estimate the cost to fill from empty.
- Step 3: If you’re starting with some fuel left, multiply the price by the fraction of the tank you need to fill (e.g., 75% of 14.8 gallons if the tank is about three-quarters full).
Remember that taxes, regional pricing differences, and pump rounding can affect the exact figure. The estimate is most accurate when you know your local price per gallon and your current fuel level.
Summary
The Honda Accord typically uses a 14.8-gallon (56-liter) fuel tank in its recent models. To estimate the cost of a full tank, multiply 14.8 by your local price per gallon, adjusting for how empty the tank is when you start fueling. Always check your specific model year’s manual or window sticker for any variations, though 14.8 gallons is the standard figure for the current generation.
