The ₩25,410 Gap That Does Not Rank Seoul and Busan

Introduction

In an illustrative worksheet, four price cells produce a striking result: the Seoul total exceeds the Busan total by KRW 25,410. The arithmetic is correct—but the conclusion “Busan is cheaper for students” would not follow from these figures.

The figures come from the Korea Consumer Agency’s regional dining-price table selected for August 2026. They are dated administrative price observations, not current restaurant quotations, campus-cafeteria prices or measured student expenses. Opening the table’s notes therefore changes the useful question from “Which city wins?” to “What exactly did these inputs allow us to calculate?”

First, freeze the inputs and their units

The selected table reports bibimbap as one normal portion and gimbap as one roll. For newcomers, bibimbap is a rice dish mixed with toppings; gimbap is a rice roll. The relevant published values are:

If the table is wider than your screen, scroll it horizontally to read every column.

Unit normalization matters. Multiplying “10 bibimbap” means ten normal portions under this table’s unit, while multiplying “8 gimbap” means eight rolls. Combining quantities without checking units could produce tidy but misleading totals.

Calculation card: an invented, replaceable basket

The quantities below are invented solely to demonstrate arithmetic. Ten bibimbap portions plus eight gimbap rolls are not a recommended diet, a monthly basket, an average or observed spending.

• Seoul: 10 × 11,923 + 8 × 3,923 = 150,614 KRW
• Busan: 10 × 9,686 + 8 × 3,543 = 125,204 KRW
• Difference: 150,614 − 125,204 = 25,410 KRW

These totals and the difference are Uni News Korea calculations using the table’s operands; the source does not report this basket or promise equivalent savings. To reuse the method, replace 10 and 8 with your own hypothetical quantities while retaining the stated units and period.

What is known—and what remains unknown

Known: these four inputs, these invented quantities and ordinary multiplication produce the displayed totals. Anyone using the same operands can reproduce them.

Unknown: what a particular student would buy; restaurant location; meal quality; campus prices; housing and transport costs; and whether the sampled offerings are equivalent. A missing price should remain UNKNOWN, never become zero.

The official notes say the figures are provisional and may change. They also caution that establishment changes can affect recorded prices and that product quality or surveyed establishments may differ across regions and periods. Holding the date and units constant does not remove that comparability problem. The material presented here also gives no sample count or detailed sampling method. Consequently, the KRW 25,410 difference supports a narrow arithmetic comparison, not a causal or representative affordability ranking.

Three information gaps to close before shortlisting

For a university decision, treat this calculation as one dated worksheet cell. Start with published campus and transport information; contact the responsible operator only about missing details. Build three campus-specific records.

1. Housing: Check each university’s accommodation options applicable to your student category, including contract duration, required deposits, included utilities and mandatory charges. Record unavailable information as unknown.
2. Food: Find current menus and prices for the campuses you might attend, noting who may access each dining facility and when. Keep those figures separate from this regional restaurant table.
3. Transport: Identify the route between the actual housing option and campus, then collect the applicable fare rules and expected trip frequency for your hypothetical schedule.

These are editorial planning suggestions, not claims that every institution publishes the information or that every applicant can access the same services. Once collected, label every input by source, date, unit and scope. That produces a more decision-relevant comparison without pretending one small food calculation is a complete living budget.
