How Maximum Affordable Fuel Price Calculator Works
This tool works by subtracting fixed transport costs and a reserve from the total budget, then finding the highest fuel price the remaining money covers for required driving.
- Step 1
Enter the total transport budget
Type the full monthly transport budget.
- Step 2
Subtract fixed costs and reserve
Enter parking, tolls, or charging fees, and a reserve percentage to keep unspent.
- Step 3
Enter required miles and MPG
Type the miles that must be driven and the vehicle MPG.
- Step 4
Read the price ceiling
The calculator shows the highest price per gallon and per liter that meets all constraints.
Maximum Affordable Fuel Price Calculator Formula
The formula divides the money left for fuel by the fuel needed for required miles.
Fuel Money = Total Budget − Fixed Costs − (Total Budget × Reserve %)
Fuel Needed = Required Miles ÷ MPG
Maximum Affordable Price = Fuel Money ÷ Fuel Needed
- Fixed Costs
- = non-fuel transport costs paid from the same budget
- Reserve %
- = share of the budget kept unspent
- Required Miles
- = distance that cannot be cut
Worked Example
- A worker has a $200 transport budget, pays $25 for parking, and keeps a 10% reserve ($20).
- Fuel money = $200 − $25 − $20 = $155.
- Fuel needed for 1,200 required miles (1,931 km) at 30 MPG = 40 gallons (151.4 liters).
- Maximum affordable price = $155 ÷ 40 = $3.88 per gallon ($1.024 per liter).

What is a Maximum Affordable Fuel Price Calculator?
A Maximum Affordable Fuel Price Calculator is a constraint-based tool that finds the highest fuel price a driver can pay while meeting required mileage, fixed costs, and a savings reserve.
Real budgets carry more than fuel. Parking, tolls, and a cushion for emergencies come out of the same money. The Maximum Affordable Fuel Price Calculator removes those items first and prices only the money left for fuel.
The price ceiling tells a driver when to act. A pump price above the ceiling means the reserve or required miles must change.
