When it comes to tracking mileage for reimbursement, Excel offers a range of formulas to simplify the process. Whether you're an employee seeking reimbursement or an employer calculating expenses, understanding these formulas can save you time and ensure accurate calculations. Let's dive into the world of Excel mileage reimbursement formulas.

Before we delve into the specifics, it's essential to have a basic understanding of the structure we'll be working with. Typically, your mileage log will include columns for date, starting mileage, ending mileage, miles driven, and reimbursement rate. The goal of our formulas will be to calculate the miles driven and the reimbursement amount.

Calculating Miles Driven
The first step in our mileage reimbursement process is to calculate the miles driven for each trip. This can be achieved using a simple subtraction formula in Excel.

Assuming your starting mileage is in cell B2 and ending mileage is in cell C2, the formula to calculate miles driven would be:
Basic Miles Driven Formula

In cell D2, enter the following formula: `=C2-B2`
This formula will automatically calculate the miles driven for each trip, assuming you've entered the starting and ending mileage for each trip in the respective cells.
Autofilling the Formula

To apply this formula to the entire range of cells, simply click on the small square in the bottom-right corner of cell D2 (called the "fill handle") and drag it down to the last cell in your range. This will automatically fill the formula into the other cells, calculating the miles driven for each trip.
Calculating Reimbursement Amount
Once you've calculated the miles driven, the next step is to determine the reimbursement amount. This involves multiplying the miles driven by the reimbursement rate.

Assuming your reimbursement rate is $0.585 per mile (as per the 2021 IRS standard mileage rate) and is entered in cell E1, the formula to calculate reimbursement amount would be:
Reimbursement Amount Formula


















In cell E2, enter the following formula: `=D2*$E$1`
This formula multiplies the miles driven (cell D2) by the reimbursement rate (cell E1). The dollar signs ($) in the formula ensure that the cell reference for the reimbursement rate remains absolute, even when the formula is autofilled.
Autofilling the Formula
As before, you can autofill this formula by clicking on the fill handle in cell E2 and dragging it down to the last cell in your range. This will calculate the reimbursement amount for each trip.
Summing Up the Totals
After calculating the reimbursement amount for each trip, you might want to sum these amounts to find the total reimbursement for the period. This can be achieved using the SUM function in Excel.
Assuming your reimbursement amounts are in column E, the formula to sum these amounts would be: `=SUM(E2:E100)`
This formula sums the values in cells E2 to E100. You can adjust the range as needed to match your data.
And there you have it! With these Excel formulas, you can efficiently track and calculate mileage reimbursement. Always remember to double-check your formulas and data to ensure accurate calculations. Happy calculating!
