Concur Mileage Calculator: How It Works

The Concur mileage calculator is a built-in feature of the SAP Concur travel and expense platform that automatically computes the reimbursable amount for business travel by car. You enter the trip date, starting point, and destination (or the distance manually), and the system applies the official IRS standard mileage rate to return the dollar amount you can claim. It also logs the trip for audit and policy compliance, so you don’t have to keep paper logs.

Formula

The Concur mileage calculator uses a simple multiplication formula:

Reimbursable amount = Distance × IRS rate

• Distance (d) – the number of miles driven for business, in miles (or kilometers if your organization uses metric).
• IRS rate (r) – the standard mileage rate set by the IRS, expressed in cents per mile. For 2025, the business rate is 67 cents per mile (as of January 1, 2025).

The result is the amount in dollars that the employee can claim. Concur applies this formula automatically when you enter a trip, but you can also override the distance if your organization requires manual entry.

Worked Example

Using the default values from the calculator above:

1. Distance = 50 miles
2. IRS rate = 67 cents/mile = $0.67 per mile
3. Reimbursable amount = 50 × 0.67 = $33.50

So for a 50-mile business trip at the 2025 IRS rate, Concur would show a reimbursement of $33.50. The calculator rounds to two decimal places, which matches Concur’s output.

How Concur Calculates Mileage

Concur offers two ways to calculate mileage:

• Automatic distance calculation – When you enter your start and end addresses, Concur uses a mapping service (like Google Maps) to compute the shortest or fastest route. It then multiplies that distance by the IRS rate.
• Manual entry – If your company doesn’t use the automatic feature, you can type the number of miles directly. Concur then applies the rate to that number.

The system also lets you split a trip into multiple legs (e.g., from home to client A, then to client B) and calculates each leg separately. This is useful for multi-stop itineraries.

How to Use the Concur Mileage Calculator

To claim mileage in Concur, follow these steps:

1. Log in to Concur and start a new expense report.
2. Select “Add Expense� and choose “Mileage� as the expense type.
3. Enter the trip date, start location, and destination (or the distance manually).
4. If your company uses automatic calculation, Concur fills in the distance and the reimbursement amount.
5. Review the amount and submit the report.

Some companies require you to attach a map or a screenshot of the route. Check your company’s policy before submitting.

Common Mistakes and Misconceptions

One common mistake is using the wrong rate. The IRS updates the standard mileage rate each year, and sometimes mid-year if fuel prices spike. For 2025, the business rate is 67 cents/mile, but your company might use a lower or higher rate for internal purposes. Always verify the current rate with your finance team.

Another misconception is that Concur automatically uses the IRS rate. In reality, the rate is set by your company’s Concur administrator. If your company hasn’t updated the rate in the system, the reimbursement might be off. That’s why it’s wise to double-check the rate before submitting.

Also, note that Concur’s automatic distance calculation may use the “shortest� route, not necessarily the one you actually took. If you took a longer route for a valid reason (e.g., road closures), you can manually override the distance, but you may need to provide a justification.

Comparing Concur’s Calculator to Other Tools

Concur’s mileage calculator is not a standalone tool; it’s part of the expense report. Other tools like MileIQ or Everlance are standalone apps that track mileage via GPS and then export to Concur. The main difference is that Concur calculates reimbursement at the time of report submission, while those apps track continuously.

If you just need a quick estimate without logging into Concur, you can use a simple calculator like the one above. It gives you the same result as Concur if you use the same rate and distance. However, for official reimbursement, you must submit through Concur.

Safety and Accuracy Tips

To ensure accurate reimbursement, keep a contemporaneous log of your business miles. The IRS requires that you record the date, destination, business purpose, and miles for each trip. Concur’s digital log can serve this purpose, but if you’re using a manual log, make sure it’s complete.

Also, be aware that the standard mileage rate includes costs like gas, maintenance, and depreciation. You cannot deduct those separately if you use the rate. This is important for tax purposes, but for expense reports, it’s the company’s policy that matters.

If you’re driving an electric vehicle, note that the IRS rate is the same, but some companies offer a separate rate for EVs. Check your policy.

Limits of the Calculator

The Concur mileage calculator is limited to the data you provide. It doesn’t account for tolls, parking fees, or congestion charges, which you must enter as separate expenses. It also doesn’t know if you took a detour for personal errands – that’s your responsibility to exclude.

For international travel, the IRS rate doesn’t apply; your company may use a different rate or a per-kilometer rate. In that case, you’ll need to convert miles to kilometers if Concur is set to miles.

Frequently Asked Questions

What is the current IRS mileage rate for 2025?
The IRS standard business mileage rate for 2025 is 67 cents per mile, effective January 1, 2025. This rate is used by many employers for reimbursement, but your company may choose a different rate.

Can I use Concur without the automatic mileage calculation?
Yes. If your company hasn’t enabled the mapping feature, you can manually enter the distance. The reimbursement amount will be calculated based on that number.

Does Concur use Google Maps for distance?
Concur partners with a mapping provider, but the exact provider may vary. The system typically uses the shortest or fastest route, depending on your company’s settings.

Can I claim mileage for a trip that includes a personal detour?
No. You should only claim the business portion of the trip. If you detour for personal reasons, subtract that extra mileage from your claim.

How do I change the mileage rate in Concur?
Only a Concur administrator can change the rate. Contact your finance or HR department if you believe the rate is outdated.

Is the Concur mileage calculator free?
Concur is a paid subscription service for companies. The mileage calculator is included in the platform, but you can’t use it as a standalone free tool. For a quick estimate, use the free calculator on this page.
