How to Use This Worksheet
- 1
Add a fill-up entry
Click 'Add fill-up' to add a new row. Each row represents one visit to a gas station. Fill in the date, the station name or location, the number of gallons you pumped, and the price per gallon from the pump.
- 2
Watch totals update automatically
As soon as you enter gallons and price per gallon, the Total column calculates the cost for that fill-up. The summary cards at the top update in real time, showing your total spent, total gallons, and average price.
- 3
Set a monthly budget (optional)
Enter a target monthly spending amount in the Monthly Budget field. A progress bar will appear showing how much of your budget you have used. It turns red when you go over budget.
- 4
Check your fill-up snapshot
After logging three or more fill-ups, an insight panel appears below the log showing your highest and lowest fill-up costs, average per fill-up, and average gallons. Use this to spot spending patterns over time.
How the Totals Are Calculated
The worksheet uses straightforward math. There are no estimates or assumptions — every number comes directly from what you enter.
Fill-up total
Gallons × Price per gallon = fill-up cost
Example: 12.5 gal × $3.459/gal = $43.24
Total spent
Sum of all fill-up totals
Example: $43.24 + $38.90 + $51.75 = $133.89
Average price per gallon
Sum of (price/gal per fill-up) ÷ number of fill-ups
Example: ($3.459 + $3.399 + $3.519) ÷ 3 = $3.459/gal average
Budget remaining
Monthly budget − total spent = remaining
Example: $200 − $133.89 = $66.11 remaining
Tips for Reducing Your Gas Budget
Log every fill-up consistently
The more fill-ups you record, the more useful the snapshot becomes. Consistent logging makes it easy to spot when your average price or volume starts creeping up.
Compare your average to the national rate
Check GasBudgeter's Gas Price Tracker to see the current national average. If your logged average is higher, it may be worth finding a cheaper station nearby.
Reduce highway speed
Fuel efficiency drops significantly above 60 mph. Slowing down slightly on longer drives can lower your fuel use and reduce how often you need to fill up.
Combine errands into one trip
Multiple short trips from a cold engine use more fuel than one longer trip. Planning stops together saves both time and gas.
Check tire pressure monthly
Under-inflated tires increase rolling resistance and reduce MPG. Keeping tires at the recommended pressure is one of the easiest ways to improve efficiency.
Set a realistic monthly budget
Look at your past fill-ups to calculate a realistic monthly average, then set your budget slightly below that. The progress bar will nudge you to be more conscious about each fill-up.
