How Much Money Will I Save on Gas Calculator

Use this calculator to estimate how much you'll save on gas by comparing current and potential fuel prices, your driving habits, and vehicle efficiency.

How to Use This Calculator

Enter your current gas price, potential new price, miles driven per month, and your vehicle's miles per gallon (MPG) to calculate your estimated monthly savings.

This calculator provides an estimate based on average driving conditions. Actual savings may vary depending on your specific driving patterns and fuel efficiency.

Formula Used

Monthly Savings = (Current Price - New Price) × (Miles Driven ÷ MPG)

Where:

Current Price = Your current gas price per gallon
New Price = The potential new gas price per gallon
Miles Driven = Number of miles you drive each month
MPG = Miles per gallon your vehicle achieves

Worked Example

Suppose your current gas price is $3.50 per gallon, you're considering switching to a station with $3.00 per gallon, you drive 1,200 miles per month, and your vehicle gets 25 MPG.

Monthly Savings = ($3.50 - $3.00) × (1,200 ÷ 25) = $0.50 × 48 = $24

In this scenario, you would save $24 per month by switching to the cheaper gas station.
