Oversize Permit Cost Calculator
An oversize load permit is not a single flat fee: it is a stack of state fees, weight surcharges, per-mile charges, escort costs and add-on services, and the total can run from a few dozen dollars for a short single-trip permit to several thousand for a superload. Enter your load dimensions, weight, route and permit type below to get an itemised estimate with the full breakdown, or scroll down for the fee formula, a worked example and what the state’s own fee schedules say.
Each service adds its midpoint average: route survey $350, bridge analysis $550, utility coordination $275, traffic control $425.

Quick Answer
An 80 ft long, 12 ft wide, 14 ft high load weighing 95,000 lbs travelling 250 miles in Texas on a single-trip permit with a front escort costs an estimated $875.00 in permit fees: a $150.00 base fee (Texas single-trip rate scaled by the 1.5x Oversize category), $75.00 for the 15,000 lbs over the 80,000 lb federal limit, $500.00 in distance fees at $2 per mile, and $150.00 for the escort. The calculator above is pre-filled with this exact trip.
Key takeaways
- Federal law caps Interstate trucks at 8.5 feet wide and 80,000 pounds; anything above those limits needs a state permit, and there is no national permit.
- Each state issues its own permit with its own fees, so a multi-state route needs a permit from every state you cross.
- The calculator classifies your load into Standard, Oversize, Large Oversize or Superload and scales the base fee 1x, 1.5x, 2x or 3x automatically.
- Every number here is a planning estimate: verify the real fee with the state DOT before you quote or dispatch.
How to use the calculator
Measure first, then enter. Start with the total vehicle-plus-load length, width and height in feet, including any overhang, then the gross vehicle weight in pounds. Pick the permit type that matches the job, the state, the route type, whether an escort is required, and any rush, weekend or additional services. Press Calculate and the tool shows every fee line separately so you can see exactly where the money goes.
A note on vehicle operating cost vs permit cost: permits are only one line of a hauling budget. Fuel, driver time, wear and insurance dwarf the permit fee on long runs, so compare the permit total against your dump truck operating cost for the full picture. If the freight crosses borders instead of state lines, see the overseas shipping cost calculator for international freight fees. Per-mile charges work the same way in other transport contexts, for example the excess mileage calculator.
How the estimate is built: the fee formula
The calculator adds nine fee lines. Every line comes straight from the tool’s own published method:
Total = Base fee × category multiplier + weight fee + distance fee + route adjustment + escort fee + rush fee + weekend fee + additional services
| Fee line | How it is computed |
|---|---|
| Base permit fee | State table for the permit type, times the category multiplier. Seven states have their own rates (for example Texas single-trip $100, New York single-trip $175); all others use the default (single-trip $125). |
| Oversize category | Superload (>150 ft, >16 ft wide, >16 ft high or >250,000 lbs): 3.0x. Large Oversize (>100 ft, >14 ft wide/high or >150,000 lbs): 2.0x. Oversize (>75 ft, >10 ft wide, >13.6 ft high or >80,000 lbs): 1.5x. Everything else: 1.0x. |
| Weight fee | $5 per 1,000 lbs over the federal 80,000 lb limit, rounded up. So 15,000 lbs over costs $75. |
| Distance fee | Only for single-trip, superload and house-move permits: $1 per mile up to 100 miles, $2 per mile beyond. Annual and multi-trip permits add no distance fee. |
| Route adjustment | Interstate $0, state highway $25, mixed route $50, local roads $75. |
| Escort fee | None $0, front or rear escort $150, front and rear $300, police escort $500. |
| Rush processing | 50 percent of the base permit fee; drops processing to 1–2 business days. |
| Weekend/holiday | $200 flat when weekend or holiday travel is allowed and used. |
| Additional services | Midpoint averages: route survey $350, bridge analysis $550, utility coordination $275, traffic control plan $425. |
One honest caveat: the tool produces a fee estimate even for a load inside legal limits (for example 60 ft long, 8.5 ft wide, 13.5 ft high at 80,000 lbs classifies as “Standard” and still prices a permit). A load that fits the legal limits may not need a permit at all, so check the thresholds first and treat the estimate as a budget number, not a filing.
Worked example: three trips, verified in the tool
All three runs below were executed in the calculator and the numbers match the displayed output exactly.
| Trip | Category | Base | Weight | Distance | Escort | Total |
|---|---|---|---|---|---|---|
| Single-trip, TX, 80/12/14 ft, 95,000 lbs, 250 mi, interstate, front escort | Oversize | $150.00 | $75.00 | $500.00 | $150.00 | $875.00 |
| Annual, FL, 60/9/13.5 ft, 80,000 lbs, 1,000 mi, mixed, front + rear | Standard | $1,000.00 | $0.00 | $0.00 | $300.00 | $1,350.00 |
| Superload, NY, 160/17/16.5 ft, 200,000 lbs, 50 mi, state highway, police escort, rush, all 4 services | Superload | $1,800.00 | $600.00 | $50.00 | $500.00 | $5,475.00 |
The superload run shows how the fees compound: the $600 New York superload base triples to $1,800 under the 3.0x Superload multiplier, the 120,000 lbs of excess weight adds $600, and rush processing adds another $900. Superload processing is estimated at 10–15 business days without rush because of the engineering and bridge reviews involved.
What other oversize calculators get wrong
The most direct rival tools return a single total from two or three inputs and no state dimension at all, which is the opposite of how the fees actually work. Real fee schedules are state-specific: Texas charges about $60 plus $0.12 per mile with $25 per foot over 14 feet wide, Florida about $35 plus $0.15 per mile, and Seattle’s city schedule runs $18 for a single oversize trip, $60 for thirty days and $290 annual. A calculator that cannot pick a state cannot estimate a real trip.
Second, rivals rarely separate permit types. Single-trip, multi-trip, annual, superload and house-moving permits have different base fees and different distance rules (annual and multi-trip permits charge no per-mile fee here), and states discount annual permits steeply against stacks of single trips. Third, escorts and services are where budgets actually break: pilot cars, police escorts, route surveys and bridge analyses can exceed the permit fee itself, yet most tools omit them. This calculator puts all nine lines on screen, classifies the load into one of four categories with its multiplier, and warns that the numbers are planning estimates to verify against the state DOT fee schedule.
Permit types at a glance
| Permit type | Best for | Distance fee |
|---|---|---|
| Single trip | One journey on a designated route | Yes ($1/mi to 100 mi, $2/mi beyond) |
| Multi-trip | Several trips within a set period | No |
| Annual | Repeat moves on the same lanes all year | No |
| Superload | Loads far beyond normal oversize limits; engineering review required | Yes ($1/mi to 100 mi, $2/mi beyond) |
| House moving | Relocating whole structures | Yes ($1/mi to 100 mi, $2/mi beyond) |
As a rule of thumb, compare the annual base fee against the number of single trips you expect: at the Texas rates in the tool ($100 single vs $800 annual), the annual wins after about eight trips in a year, and real state programs often discount annuals by roughly 60 percent against stacked single trips.
Frequently asked questions
Yes. Any excess over the legal limit triggers the permit requirement, even by an inch or a thousand pounds. On the Interstate the federal baseline is 8.5 feet wide and 80,000 pounds gross vehicle weight, and each state enforces its own dimensional thresholds.
State base fees for a single trip commonly run from about $18 to $175 depending on the state and permit type, and the total trip cost climbs with weight surcharges, per-mile fees, escorts and services. A routine single-trip oversize move often totals a few hundred dollars; a superload with escorts, rush processing and bridge analysis can reach several thousand.
Yes. There is no national oversize or overweight permit: the federal government does not issue them, and each state DOT runs its own program with its own fees, escort rules and routing restrictions. A load crossing three states needs three permits.
A superload is a load far beyond normal oversize limits. In this calculator the Superload tier starts above 150 feet long, 16 feet wide or high, or 250,000 pounds, and it carries a 3.0x base-fee multiplier. Real superloads need engineering and bridge reviews, which is why the calculator estimates 10 to 15 business days of processing.
Run the math on your lane. If you haul similar oversize loads repeatedly on the same routes, an annual permit usually costs far less than a stack of single trips: some states effectively discount annuals by about 60 percent against stacked single-trip fees. For one-off or varied routes, single-trip permits are cheaper.
No. Escort requirements depend on the load dimensions, the route and the state. Many states require one or two pilot cars once a load passes roughly 12 to 14 feet wide, and reserve police escorts for the most extreme moves. The calculator prices each option so you can compare.
Because this tool is a planning estimator, not the state’s official filing system. Its base fees are representative averages for budgeting; actual state fees, tonnage formulas and accessorial charges change and vary by corridor. Always verify the final number against the state DOT fee schedule before quoting or dispatching.
