Mileage and fuel formulas
The calculator converts kilometers to miles for reimbursement while preserving the entered unit for the trip display. Metric fuel economy is liters per 100 kilometers rather than kilometers per liter.
total=one way×(round trip?2:1)×tripsUS gallons=miles÷MPGmetric liters=kilometers×L/100 km÷100Worked repeated-trip example
A 25-mile trip to a destination and back is 50 miles. Repeating it four times produces 200 logged miles before applying any reimbursement rate.
About the 2026 IRS rate
The editable default reflects the IRS business rate for July 1 through December 31, 2026. Rates and eligible uses change, and the standard mileage method is optional where allowed.
Reimbursement is not fuel cost
A mileage allowance can reflect fixed and variable vehicle costs, while the fuel estimate covers only entered fuel price and consumption. Do not subtract fuel cost to infer a tax deduction without applying the relevant rules.
Records and route limits
Keep dates, destination, business purpose and miles when documentation is required. This local calculator does not geocode addresses, choose a route or account for detours, traffic and personal miles.
