Washington Toll Calculator

What Is the Washington Toll Calculator?

The Washington Toll Calculator is an online tool that estimates how much you’ll pay in tolls based on your route, vehicle type, and payment method. It’s designed for:

• Daily commuters driving across I-405 or SR 520
• Casual travelers visiting Seattle or Bellevue
• Truckers and fleet managers who need cost planning
• Out-of-state visitors unsure how Washington tolling works

The calculator uses real-time tolling rules, including variable pricing and discounts, to give you accurate estimates.

How Washington Toll Roads Work

Unlike some states with toll plazas, Washington uses all-electronic tolling. That means:

1. Good To Go! Pass (best option)
   • Washington’s official tolling transponder
   • Provides the lowest toll rates
   • Works on all Washington toll roads and bridges
2. Pay By Plate
   • Cameras capture your license plate
   • Bills mailed to the registered vehicle owner
   • Costs more than using a Good To Go! pass
3. Short-Term Accounts
   • Option for occasional drivers
   • Lets you prepay tolls without buying a permanent pass
