How much does a trip to Korea cost?

Four parts of a Korea trip have prices we can read every day and re-read tomorrow: the flight, the airport transfer, mobile data and city transport. Those are the only parts we put a number on.

Right now the cheapest one-way fare we have observed to Incheon is $80 from Taipei for 2026-09-19, a week of mobile data starts at $9, and the Seoul subway charges ₩1,550 a ride by card.

We do not price accommodation, food or attractions — we cannot re-read those on a schedule, and a total that assumes where you sleep and how you eat is an estimate wearing the clothes of a measurement. Put your own trip in below and each line will show what it costs, and how much of it is decided by which option you take.

For one traveller over 7 nights — flights, airport transfer, mobile data and city transport. Not accommodation, food, attractions or insurance; those are listed below with the reason.

On top of the total above, if you take the dearest option on each line instead of the cheapest. Counted on 3 of 4 lines — every figure is the difference between two prices we actually collected, and lines where the options are not genuinely interchangeable are left out rather than padded.

Each line is one tool — open it to put in your own numbers instead of ours. We are paid on 3 of these 4 lines; where the cheapest answer is something we cannot sell you, the row says so instead of pointing you at the second-cheapest thing that pays us.

Airport transfer is the cheapest option outright, which means the all-stop train and its transfers and stairs; if you would rather not do that with bags, the express train is the next line up. A late-night landing removes both entirely, which changes the answer — the transfer tool handles that. City transport assumes 4 boardings a day at ₩1,550 each; the pass calculator takes your own number. Fares collected 2026-08-11. eSIM plans collected 2026-08-11.

What this total leaves out, and why

Accommodation — We can get affiliate links for hotels but not prices we can re-read on a schedule, and a nightly rate that we cannot re-check is a rate we will not print.
Food — There is no published tariff to read. Any figure would be our estimate of how you eat, which is a different kind of claim from the ones on this page.
Attractions and tours — Prices exist and are readable, but what you would actually visit is not something we can derive. A total that assumes an itinerary is an invented total.
Travel insurance — Premiums are quoted per traveller from age, trip length and cover level, so there is no single price to publish. We compare what the policy does instead.

Same trip, next decision

Why we show you what not to buy

Sites that pay you cashback can only reward a purchase. That sounds like it is on your side, and on the buy-it branch it is — but it means they can never tell you that the pass is not worth it, that the plan you were about to take is longer than your trip, or that four of you should split a taxi rather than buy four train tickets. Their revenue and their advice point the same way, and it is not always your way.

We take a commission when you buy through us, and we say so on every page that carries a link. What we do not do is make our advice conditional on the purchase: the transit calculator tells a lot of short-trip visitors to buy nothing at all, and the licence check hides the rental link entirely when your licence will not work in Korea. The avoidable figure above is the honest version of cashback — money you never spend rather than a slice of money you did.

Quick answers

How much does a week in South Korea cost?

The part that can be measured from published prices — the flight, the airport transfer, mobile data and city transport — is the only part we will put a figure on, and we recalculate it daily from collected prices. Accommodation, food and attractions are excluded because we cannot re-read a price for them on a schedule, and a total that assumes how you eat or where you sleep is an estimate rather than a measurement.

What is the cheapest way to get from Incheon Airport into Seoul?

The all-stop airport train, on the fares we hold. A taxi is priced per car rather than per person, so splitting it sounds like it should win with a group — but it does not at any group size we can model, because a taxi seats four and two taxis cost more than four train tickets by a wide margin. What does change the answer is the hour: a late-night arrival removes the train and the limousine bus from the comparison altogether, and then a pre-booked transfer or a taxi is what is left.

Do I need a Seoul transit pass?

Only above a certain number of boardings. The Seoul subway base fare is ₩1,550 by transport card, so a ₩5,000 one-day Climate Card needs about four rides in the day to beat paying per ride, and the ₩20,000 seven-day card needs about two a day. Below that, paying per ride is cheaper and no pass is worth buying.
