Enter gallons and price per gallon, then check the fuel total and optional donation. Add pump, transaction and card references before saving the receipt.

The Shell layout calculates a fuel amount from volume and unit price. It also has an optional donation line with a recipient and a rate per rounded gallon. Payment and terminal references appear below the total, making it easy to check the charge and any added amount together.
