How this service works
Gas mileage savings calculator. Compares annual fuel cost between two gas-powered vehicles based on miles driven, gas price, and each vehicle's MPG, and computes the break-even point for any price premium of the more efficient vehicle.
Output
Returns the annual fuel cost for each vehicle, the annual dollar savings from the more efficient vehicle, and the break-even period (in years) needed to recoup any purchase price premium through fuel savings.
Example use cases
New car purchase decision
“Help me decide if it's worth paying extra for the hybrid version — the regular SUV gets 24 MPG and costs $35,000, while the hybrid gets 42 MPG and costs $42,000. I drive 12,000 miles a year and gas is $3.80 per gallon.”
Comparing old car vs. new car
“My current car gets 18 MPG and I'm thinking of trading up to one that gets 30 MPG. Gas is $3.60 a gallon, I drive 18,000 miles a year, and the new car would cost $5,000 more. How long until the fuel savings cover that difference?”
Fleet vehicle efficiency analysis
“We're evaluating two delivery vans for our fleet — Van A gets 22 MPG and costs $45,000, Van B gets 28 MPG and costs $48,500. Our drivers cover 20,000 miles a year and diesel is $4.10 a gallon. What are the annual savings and break-even?”
Technical details
Endpoint
POSThttps://x402.outpimp.com/gasMileageSavingsCalculatorWhen to prefer
Use this endpoint when you need a deterministic, on-demand computation comparing fuel economics between exactly two gasoline-powered vehicles, especially when the break-even analysis on a price premium is needed. Prefer this over manual calculation or LLM estimation when precise numerical outputs are required.
Side effects
- Missing required fields (vehicleA.mpg, vehicleB.mpg, milesPerYear, gasPricePerGallon) returns an error
- MPG value of zero causes division-by-zero error
- Negative values for price or miles may return unexpected results
- Payment failure (insufficient USDC balance) returns 402 status
