Why $0.59 Beats $0.70: What 2025 Mileage Reimbursement Data Tells Us About Cost Efficiency

If your business is still relying on the IRS standard mileage rate for employee reimbursements, here’s something worth thinking about: the IRS standard mileage rate has increased to $0.70 per mile in 2025. 

That’s up from $0.67 per mile in 2024, continuing a trend of rising reimbursement costs driven by inflation, fuel volatility, and vehicle ownership expenses.

But here’s the kicker. Companies using Fixed and Variable Rate (FAVR) reimbursement programs reported an average cost per mile of just $0.59 in 2025. That’s an 11-cent difference per mile. 

Multiply that by thousands of miles driven each year by employees, and you’re staring down a major opportunity for savings.

IRS Rate vs. FAVR: What’s the Difference?

The IRS mileage rate is a standardized figure intended to cover the average cost of operating a vehicle for business purposes. It’s simple, easy to adopt, and tax-free if managed under an accountable plan. 

But the one-size-fits-all nature of this mileage rate often leads to over-reimbursement for low-mileage drivers and under-reimbursement for high-mileage drivers.  

By contrast, FAVR programs calculate reimbursements based on actual costs in each employee’s geographic area and their specific driving patterns. 

There’s a fixed monthly component for ownership expenses (depreciation, insurance, registration) and a variable mileage component for operational costs (fuel, maintenance, tires). This dual-component system adapts to real-world conditions, ensuring fair and accurate reimbursements.

Why $0.59 per Mile Matters

The fact that companies running FAVR programs average $0.59 per mile in 2025 is more than just a statistic. It’s a benchmark of operational efficiency. 

It proves that reimbursements can be both fair to employees and cost-effective for businesses. While the IRS rate protects companies from tax liability, it doesn’t protect them from overpaying.

For example, if a sales rep drives 15,000 miles per year, the difference between reimbursing at $0.70 vs. $0.59 is $1,650 annually. Multiply that by 100 employees and you’re looking at $165,000 in potential savings.

How FAVR Achieves Savings

FAVR saves money because it eliminates the blanket approach. Drivers in high-cost areas receive higher reimbursements, while those in lower-cost areas don’t get more than they actually spend. The program’s design inherently avoids the pitfalls of flat car allowances and standardized rates, which often distort true costs.

Plus, when powered by software that automates mileage tracking and rate calculation, FAVR programs minimize administrative time and ensure IRS compliance. This not only streamlines operations but reduces audit risk and tax exposure.

Is FAVR Right for Your Team?

Not every business will benefit equally from FAVR. It’s best suited for organizations with at least five drivers who each log 5,000 or more business miles per year. 

But if that sounds like your team, then the math supports the switch. You get accurate, equitable reimbursements, employees get reimbursed tax-free, and the organization avoids unnecessary costs.

Why Mileage Rates Demand a Smarter Reimbursement Strategy

The rising IRS mileage rate reflects a challenging cost environment for all vehicle programs. But it also underscores the need for smarter solutions. 

FAVR programs offer a tailored, compliant, and data-driven way to reimburse drivers fairly while keeping costs below national averages.

In 2025, that difference is clear: $0.70 vs. $0.59. Which number will define your company’s vehicle reimbursement strategy?

Switching from a flat car allowance to an IRS-compliant, mileage-based reimbursement, especially a FAVR program, can cut wasteful payroll taxes, aligns payments with real costs, and often reduces spend by around 30 percent.
