Texas Toll Calculator

What Is the Texas Toll Calculator?

The Texas Toll Calculator is an online tool that estimates how much you’ll pay when using toll roads in Texas. It works by taking in details such as:

• Start and end locations – entry and exit points on tollways
• Vehicle type – car, motorcycle, SUV, truck, or commercial vehicle
• Payment method – electronic tag (TxTag, EZ TAG, TollTag) or Pay By Mail
• Trip type – one-way or round trip

The calculator then provides:

• Total toll cost for your trip
• Itemized toll plaza charges along the route
• Savings comparison between tag payment and Pay By Mail

How Texas Toll Roads Work

Texas toll roads are fully electronic. That means:

1. Electronic tags (best option)
   • Options include TxTag, EZ TAG, and TollTag
   • Lowest rates available
   • Funds are deducted automatically as you drive
2. Pay By Mail
   • Cameras capture your license plate
   • A bill is mailed to the registered vehicle owner
   • Costs more than using an electronic tag
   • Additional fees may apply if unpaid

Example Trip Using the Texas Toll Calculator

Let’s look at a common route:

• Route: Driving from Austin (I-35) to San Antonio via SH 130 toll road
• Distance: Around 90 miles
• Vehicle: Passenger car

Estimated tolls:

• With TxTag/EZ TAG/TollTag: Around $12 – $14 one way
• With Pay By Mail: Around $18 – $20 one way

That’s a savings of up to 30% just by using a tag.
