Kansas Toll Calculator
The Kansas Turnpike went fully cashless on July 1, 2024, and your toll now depends on three things: how far you drive, your vehicle class, and whether you pay with a K-TAG or by license plate. K-TAG users pay exactly half the license-plate rate on every mile, so the payment method you pick matters as much as the distance. Enter your start and end mile markers, your axle count and your payment method below to get an estimate from the Kansas Turnpike Authority’s published per-mile schedule, with the K-TAG comparison shown on every result.
Estimate only. The Kansas Turnpike Authority sets final prices; confirm at ksturnpike.com. Rates are the KTA published cashless schedule in effect from July 2024. The KTA raised tolls on September 1, 2026 (3% passenger, 4% commercial) and had not published a revised per-mile table as of October 22, 2026, so billed tolls now run a few percent above these estimates.
Quick Answer
A 2-axle car driving 160 miles on the Kansas Turnpike, roughly Wichita to Topeka, pays $7.68 with a K-TAG and $15.36 by license plate at the KTA's published cashless rates. The full 236-mile run from the Oklahoma border to Kansas City estimates at $11.33 with a K-TAG. One warning: tolls rose on September 1, 2026 (3% passenger, 4% commercial) and the KTA has not published a revised per-mile table yet, so real bills now run a few percent higher than any estimate from the published schedule.
How to use the Kansas Toll Calculator
Enter the mile marker where you get on and the one where you get off, pick your axle class and payment method, and tick round trip if you are driving back.
- Start and end mile markers. The turnpike runs from mile 0 at the Oklahoma border to mile 236 at Kansas City. Wichita exits sit roughly between miles 42 and 53, with Emporia near mile 127, Topeka near mile 182 and Lawrence near mile 204.
- Vehicle axles. Count axles on the vehicle plus any trailer. Cars, pickups and motorcycles are class 2; a standard semi-trailer is class 5; the schedule runs to class 9.
- Payment method. K-TAG is the transponder rate. License plate billing is exactly double, and cash is not an option anywhere on the road.
- Read the result. You get the estimated toll, the distance and rate behind it, and the other payment method's price for the same trip, so the K-TAG saving is a number, not a slogan.
Tolls are only one line of a trip budget. If you are costing a regular drive, the commute expense calculator adds fuel, wear and parking to the same journey, and the cost per trip calculator splits a one-off drive into its parts.
The KTA rate schedule this calculator uses
The table below is the Kansas Turnpike Authority's published cashless schedule, the per-mile rates the authority set when cashless tolling launched in July 2024, as printed in the KTA's own cashless tolling guide and its toll rate policy. An earlier version of this page carried a different table for the truck classes; those figures did not match the KTA schedule and have been corrected, class by class.
| Class (axles) | K-TAG per mile | License plate per mile | Full 236 miles, K-TAG | Full 236 miles, plate |
|---|---|---|---|---|
| 2 (car, pickup, motorcycle) | $0.048 | $0.096 | $11.33 | $22.66 |
| 3 | $0.066 | $0.132 | $15.58 | $31.15 |
| 4 | $0.092 | $0.184 | $21.71 | $43.42 |
| 5 (typical semi-trailer) | $0.138 | $0.276 | $32.57 | $65.14 |
| 6 | $0.187 | $0.374 | $44.13 | $88.26 |
| 7 | $0.258 | $0.516 | $60.89 | $121.78 |
| 8 | $0.303 | $0.606 | $71.51 | $143.02 |
| 9 | $0.334 | $0.668 | $78.82 | $157.65 |
The full-length columns are per-mile estimates from this calculator. The KTA bills at 21 gantries and rounds each transaction, so its own quoted full-length totals sit a few cents higher: $11.36 for a car with a K-TAG, and about $32.69 for a 5-axle truck. Expect that same few-cents gap on any long trip.
Worked example: mile 50 to mile 210
The pre-filled run is a 160-mile drive, about Wichita to Topeka, in a 2-axle car. Three versions of the same trip show what each choice costs.
| Run | Math | Estimated toll |
|---|---|---|
| 2 axles, K-TAG, one way | 160 x $0.048 | $7.68 |
| 2 axles, license plate, one way | 160 x $0.096 | $15.36 |
| 5 axles (semi), K-TAG, one way | 160 x $0.138 | $22.08 |
| 2 axles, K-TAG, round trip | 160 x $0.048 x 2 | $15.36 |
Same 160 miles with a K-TAG, by class: car $7.68, 5-axle semi $22.08, 9-axle combination $53.44.
Every figure in both tables reproduces in the calculator above. The truck row is the one this page most needed to get right: at the wrong rate an earlier table carried, that semi run overstated the toll by almost $15.
The September 2026 increase, stated plainly
Rates are not frozen at the published schedule. The KTA board approved a three-year adjustment in 2026: tolls rose on September 1, 2026 by 3% for passenger vehicles (classes 2 to 4) and 4% for commercial vehicles (5 axles and up), the first increase since 2022, funding a roughly $500 million investment program across the system.
What the authority has not done, as of October 22, 2026, is publish a revised per-mile table. Its cashless guide still prints the July 2024 schedule this calculator uses. So the honest position is: these estimates are built on the last per-mile schedule the KTA published, and your actual bill will run about 3 to 4% above them until a new table appears. When the KTA publishes one, this page's table is the thing that changes. Until then, treat any Kansas toll page claiming exact current truck rates with suspicion, including, on the truck classes, the earlier version of this one.
What competing calculators miss
The KTA's own toll calculator gives the authority's exact gantry total for an entry and exit, and for the number you owe, nothing beats it. It does not show you a per-mile table, does not price a round trip in one run, and never shows you what the other payment method would have cost, which is the comparison that actually changes behaviour.
Third-party tools have their own gaps. TollGuru routes you across every Kansas toll road and adds fuel, which is genuinely useful, but its published Kansas class table lists a 5-axle truck at $0.231 per mile and classes 6 to 9 at $0.303 and up, figures that contradict the KTA's own published schedule of $0.138, $0.187, $0.258, $0.303 and $0.334. At least one other Kansas toll page still walks you through choosing cash as a payment method, more than two years after the last cash lane closed. And the guide-style pages that get the car numbers right rarely price a truck at all.
This page's offer is narrower and more checkable: mile-marker entry for any start and end, the corrected KTA schedule printed in full next to the tool, both payment prices on every result, a round-trip toggle, and a stated rate year with the known 2026 increase disclosed instead of hidden. For the drive itself, pair the toll with the driving time calculator for the hours, and the cost per 100 miles calculator if you are comparing vehicles on a long run.
Frequently Asked Questions
It depends on how far you drive, your axle class and how you pay. A 2-axle car pays $0.048 per mile with a K-TAG and $0.096 per mile by license plate, so the full 236-mile turnpike estimates at $11.33 with a K-TAG and $22.66 by plate. Your billed total can land a few cents away from the per-mile estimate, because the KTA charges at 21 gantries and rounds each transaction separately; the authority's own full-length figure for a car is $11.36.
It uses the Kansas Turnpike Authority's published cashless per-mile schedule: the rate table the KTA set for the start of cashless tolling in July 2024, with license-plate rates at exactly double the K-TAG rates. One staleness warning: the KTA raised tolls on September 1, 2026, by 3% for passenger vehicles and 4% for vehicles with 5 or more axles, the first step of a three-year plan. The authority had not published a revised per-mile table as of October 22, 2026, so expect billed tolls to run roughly 3 to 4% above these estimates until it does.
K-TAG is the Kansas Turnpike Authority's windshield transponder, linked to a prepaid or postpaid account on the DriveKS system. It saves exactly half on every mile: license-plate billing is priced at double the K-TAG rate for every vehicle class, with no exceptions in the published schedule. Compatible transponders from Texas, Oklahoma and Colorado also work on the turnpike through the Central US Hub.
No. The turnpike went fully cashless on July 1, 2024, and the toll booths and cash lanes are gone. Overhead gantries either read a transponder or photograph your license plate, and plate customers are billed through DriveKS. There is no way to hand cash to anyone anywhere on the 236 miles.
By axle class and distance, using the same per-mile schedule. With a K-TAG the published rates are $0.138 per mile for 5 axles, $0.187 for 6, $0.258 for 7, $0.303 for 8 and $0.334 for 9, and license-plate billing doubles each one. A 5-axle semi driving 160 miles therefore estimates at $22.08 with a K-TAG. Note that the September 2026 adjustment raised commercial rates by 4%, so billed truck tolls now run above the table.
Three reasons. First, the KTA does not charge one per-mile amount for your whole trip: it charges flat segment tolls at 21 gantries and rounds each transaction to the nearest cent, so totals drift a few cents from any per-mile estimate. Second, the September 1, 2026 increase of 3% for passenger vehicles and 4% for commercial vehicles is not yet reflected in a published per-mile table. Third, if a plate bill goes unpaid past its due date, DriveKS adds fees that no toll calculator includes.
Exactly double the one-way toll in this model, which is what the round-trip checkbox applies. The pre-filled example, mile 50 to mile 210 in a 2-axle car with a K-TAG, is $7.68 one way and $15.36 as a round trip. Real bills can differ by a few cents because each direction is charged and rounded gantry by gantry.
The KTA's own toll calculator on its website gives the authority's figure for your exact entry and exit, and that figure is final. Plate bills are paid through DriveKS, the KTA's billing platform, which also handles K-TAG accounts. Use this page for planning and comparisons; use the KTA for the number you actually owe.
