IRP fee estimator
Apportioned registration splits each jurisdiction's full-year fee by the share of your fleet miles run there. This estimator computes those distance percentages from your own miles and, when you add a jurisdiction's published full-year fee for your weight, the apportioned share. It stores no fee schedule and invents no number.

Apportion your fleet's miles
Estimate only, not a registrationEnter the miles you run (or estimate) in each jurisdiction; the tool computes each jurisdiction's share of your total distance. This site stores no jurisdiction's fee schedule, so to turn a percentage into dollars, add the full-year fee for your weight from the schedule your base jurisdiction publishes, and the tool apportions it.

The apportionment math, from the agencies
Apportioned by mileage: registration fees are pro-rated based on the percentage of highway mileage traveled in each IRP jurisdiction. For example, a fleet running 50 percent of its miles in California and 50 percent in Nevada pays 50 percent of each state's registration fees rather than full fees to both.
Fees are apportioned: each jurisdiction's fee equals the fleet's mileage percentage in that jurisdiction multiplied by that jurisdiction's registration fee schedule for the vehicle's weight. FLHSMV's published example totals 1,121.45 USD for an 80,000 lb unit across its jurisdictions; actual fees vary by fleet mileage distribution and weight.
Registration fees are apportioned: the carrier pays New Mexico a share of each jurisdiction's full registration fee based on the percentage of total fleet miles traveled in that jurisdiction, and New Mexico distributes the other jurisdictions' shares to them. The base jurisdiction may also charge additional fees for issuing credentials or for filing an apportioned-registration application; no member jurisdiction may impose a minimum registration fee on an apportionable vehicle.
Where the fee inputs come from
The percentages are the easy half; the full-year fees come from each jurisdiction's own published schedule for your declared weight. Start from the IRP offices and members reference to find your base jurisdiction's program, and use the state pages for the filing process where this site has them:
- California IRP registration
- Florida IRP registration
- Kentucky IRP registration
- New Mexico IRP registration
- New York IRP registration
- Oregon IRP registration
- Texas IRP registration
Apportioned plates are one line in the same recurring stack as fuel tax: the miles you enter here are the same jurisdiction split the quarterly IFTA calculator works from, and heavy units also owe the annual highway use tax on Form 2290.
Frequently asked questions
How are IRP fees calculated?
- Fees are apportioned: each jurisdiction's fee equals the fleet's mileage percentage in that jurisdiction multiplied by that jurisdiction's registration fee schedule for the vehicle's weight. FLHSMV's published example totals 1,121.45 USD for an 80,000 lb unit across its jurisdictions; actual fees vary by fleet mileage distribution and weight.
Why does this tool not show my state’s fee schedule?
- Because storing one honestly is not possible at this site’s standard: every member jurisdiction publishes its own schedule, the amounts vary by declared weight, vehicle type, and year, and several states publish them only inside registration systems or PDFs that change without notice. The estimator does the apportionment math and points you at your base jurisdiction’s published schedule for the fee inputs.
How much do apportioned plates cost?
- It depends entirely on your weight and your mileage split. The IRP manual illustrates the apportioned calculation as mileage percentage multiplied by each jurisdiction's full fee: for example New Mexico 50 percent of $172.00 equals $86.00, Texas 25 percent of $840.00 equals $210.00, and Arizona 25 percent of $3,957 equals $989.25, for a total registration fee of $1,285.25.
Do I pay each state separately?
- Under IRP a carrier files one application with its base jurisdiction instead of registering separately in every jurisdiction. New Mexico issues registration documents for each vehicle; only one license plate and one cab card are issued per commercial vehicle. New accounts, renewals and supplements are handled by the Commercial Vehicle Bureau. The USDOT number of the motor carrier responsible for the safety of each registered vehicle must be identified during registration under the PRISM program, and carriers must complete the biennial update every two years.
