Example Calculation
Let’s understand how the Gas Fill Up Calculator works with a real example:
- Tank Size: 15 gallons
- Current Fuel: 40%
- Fuel Price: $3.50 per gallon
Step 1: Calculate Fuel Needed
Fuel Needed = Tank Size × (1 − Current Fuel / 100)
= 15 × (1 − 40/100)
= 15 × 0.60
= 9 gallons
Step 2: Calculate Total Cost
Total Cost = Fuel Needed × Price
= 9 × 3.50
= $31.50
So, you will need 9 gallons of fuel and it will cost you $31.50 to fill your tank.
