Quick answer

Toll cost = toll miles × rate per mile, plus per-plaza charges; pay-by-plate billing typically costs 25–50% more than a transponder.

Tolls = miles × rate + plazas × fee

Frequently asked questions

Is a transponder worth it for one trip?

Often yes. Pay-by-plate adds a surcharge plus an admin fee per invoice, and many agencies post free or refundable transponders.

Do rental cars charge extra for tolls?

Yes — most add a daily convenience fee on top of the toll itself, which can cost more than the tolls on a short trip.
