Why Your NEMT Business Needs a Fuel Surcharge Policy
Fuel is one of the largest variable expenses for any Non-Emergency Medical Transportation provider. When you sign a contract with a broker or establish a standard private pay rate, you do so based on the prevailing cost of fuel at that time. If gas prices spike by $1.50 a gallon over the next six months, those sudden costs eat directly into your bottom-line profit.
Implementing a Fuel Surcharge (FSC) allows you to automatically adjust your rates to compensate for fuel inflation without having to continuously renegotiate base contracts. It acts as a safety valve for your profit margins.
How is a Fuel Surcharge Calculated?
A standard fuel surcharge calculation requires understanding the "efficiency gap" between your baseline costs and current market reality. The calculation usually involves three core metrics:
- Base Fuel Price: The price of fuel per gallon mapped to your normal base trip rate. For example, if you set your rates when gas was $3.00, that is your baseline.
- Current Fuel Price: The actual price you are paying at the pump today. You can calculate this based on the weekly EIA (Energy Information Administration) national or regional average.
- Vehicle Fuel Efficiency (MPG): A standard NEMT wheelchair van typically gets between 12 to 16 MPG. A sedan might get 25 MPG. The efficiency directly dictates how heavily the price inflation impacts the trip.
By dividing the total trip miles by the vehicle's MPG, you determine the gallons used. Multiplying those gallons by the difference between the current price and base price yields your exact unrecovered cost—which becomes your required surcharge.
Adding Surcharges to Broker Contracts vs. Private Pay
While passing on a fuel surcharge to Private Pay facilities (like Nursing Homes or assisted living facilities) is entirely within your control and should be built directly into your Master Service Agreement (MSA), enforcing them with state-sponsored brokers is more difficult. You must explicitly negotiate fuel escalation clauses into your broker SLAs prior to signing.
Frequently Asked Questions
How do I bill a fuel surcharge on an invoice?
The most transparent way is to list it as a separate line item. For example, invoice the "Base Trip Rate: $150.00" on line one, and "Fuel Surcharge: $5.40" on line two. This clearly demonstrates to the client that you have not arbitrarily raised your rates, but are applying a necessary metric-driven fee.
Should I use a percentage or a flat fee?
Many NEMT providers prefer converting the surcharge into a percentage to add onto the base rate, as it creates a scalable standard to apply to all invoices easily. However, a flat-fee calculated on exact mileage (like our calculator uses) is technically more accurate.
What index should I use to track gas prices?
Do not rely on the gas station across the street from your office. Standardize your pricing by using the U.S. Energy Information Administration (EIA) Weekly Retail On-Highway Diesel and Gasoline prices index. Referencing a government index prevents disputes with facilities over your pricing data.
If fuel drops below the base rate, do I give a discount?
In standard commercial transport contracts, if the current fuel price drops below your established base fuel price, the surcharge mathematically becomes zero ($0.00). You do not issue a negative surcharge or discount on the base rate, as the base rate is the floor of profitability.
