길값셈 - 고속도로 통행료 감면

You pay on the spot to see "How much can I save on this toll?"

There are ten types of highway toll reductions, with reduction rates ranging from 100% to 10%. Furthermore, eligibility is not determined solely by qualification—commuter discounts consider distance and departure time, multi-child discounts consider the day of the week, and late-night freight discounts consider the driving ratio. Once you select your vehicle and qualification just once, "Road Value Calculator" shows you exactly what percentage applies to each toll and how much you will have to pay.

■ Barriers Rise According to Reduction Rate

Above the toll booth diagram, the barriers rise by the reduction rate for this toll, and bars appear for each selected reduction category. If there is overlap, only the highest reduction rate is applied, so only the winning bar appears dark. A single line of tolls is divided into the portion reduced and the portion paid.

■ Record — Amount Saved by Month and Reduction

The recorded tolls accumulate into bars showing the amount saved by month and a bar indicating "What Saved."

■ Notification on the Day Before Holiday Exemption

Notification is provided on the morning of the day before the Lunar New Year and Chuseok toll exemptions (for the day before, the day of, and the following day) begin.

■ Determination of Discount Rates by Category — Only the Highest Rate Is Selected in Case of Overlap

If you enable Light Vehicles, Electric/Hydrogen Electric Vehicles, Disabled Persons, Agent Orange Aftereffects (or Medical) Sustainability, Persons of National Merit, Commuters, Late-Night Freight, or Multi-Child Families, the percentage applied to each line and the reasoning behind it will be displayed. Even if you qualify for more than two categories, the rates are not added; only the highest discount rate is applied (Proviso to Article 8, Paragraph 3 of the Enforcement Decree of the Toll Road Act) — Therefore, it is important to determine which category won the discount for this particular trip.

■ Identifying the 0% Discount Spot — This is where people are most likely to make mistakes

The Commuter discount applies only to sections under 20km; it is 50% for exits between 05:00 and 07:00 or 20:00 and 22:00, but 20% for other commuting hours. It does not apply at all on weekends. Conversely, the Multi-Child discount applies only on weekends and public holidays. The app first notifies you of cases where the device is turned on but you are unable to receive the service.

■ 15-Minute Timer for Mistaken Exit and 3-Time Annual Counter

Starting October 1, 2026, even if you exit incorrectly, you will not have to pay the basic fee of 900 won again if you re-enter the same toll booth within 15 minutes. However, this is limited to 3 times per vehicle per year. Since Hi-Pass terminals do not notify you of this, no one keeps track of how many uses remain. Pressing a single button the moment you exit incorrectly counts the remaining time and also remembers how many times you have used it this year.

■ Holiday Exemption Window and Discount Sunset D-Day

For Lunar New Year and Chuseok, tolls are waived for three days: the day before, the day of, and the day after. Since the dates shift every year due to the lunar calendar, the app first indicates how many days remain until the next exemption. Conversely, some items end in the opposite way — the discount for electric and hydrogen vehicles drops to 20% in 2027 and ends at the end of that year, late-night freight discounts end at the end of 2026, and multi-child discounts run until August 2029. It counts down to the earliest expiring of the exemptions I have enabled.

■ Savings accumulate this year
Since exemptions amount to only a few hundred won at a time, looking at a single one is meaningless; they only become visible when accumulated. If you save your assessed tolls, it shows how many tolls were discounted this year, how much was actually paid, and how many were saved. Since the data is frozen at the exemption rate at the time of saving, the answer remains even if the criteria change later.

■ Numbers are not stored in the app
Exemption rates change due to amendments to enforcement decrees, and each clause has a separate expiration date. The "Road Value Calculator" updates the standard value remotely once a day, and the app automatically notifies you if the table becomes worn out.

■ It is completed within the device
It does not collect identity information such as name, resident registration number, or vehicle number. The data entered remains only within this device, and there is no login or membership registration.

※ This app is for unofficial reference only and is not affiliated with any institution. It does not replace the application or inquiry of exemptions. The exemption for mistaken entry and the discounts for multi-child families and electric vehicles apply to expressways operated by the Korea Expressway Corporation and exclude privately operated expressways. To actually receive the exemption, prior registration by category and a dedicated payment method are required, and the app does not determine whether the event is a public holiday. Please check the expressway toll guide or the relevant agency to confirm actual applicability.
