Formulas Used
1. Daily Gallons Used
This is the amount of fuel your vehicle consumes each day based on how many miles you drive and your vehicle’s fuel efficiency (MPG).
2. Daily Gas Cost
This shows how much money you spend on gas each day, calculated by multiplying the daily gallons used by the current gas price.
3. Monthly Gas Cost
An estimate of your total gas expense in a month, based on your daily driving habits. It's calculated by multiplying the daily gas cost by 30.
4. Annual Gas Cost
This is your total estimated gas expense for the whole year, assuming you drive the same distance daily. It multiplies the daily cost by 365.
5. Annual Gallons Used
This is the total number of gallons your vehicle uses in a year, based on your daily driving and MPG.
