How mileage reimbursement is calculated
The formula is simple: business miles × reimbursement rate = reimbursement amount. For example, 500 business miles at 76 cents per mile equals $380.00.
IRS rate vs employer rate
The IRS standard mileage rate is commonly used for business mileage calculations, but an employer may reimburse at a different rate. Use the custom-rate field when your company policy differs from the IRS rate.
What this calculator does not determine
This tool calculates the dollar amount from the miles and rate you provide. It does not determine whether a trip qualifies as deductible business mileage or whether an employer is required to reimburse it.
