How it works
TWIX Salary Indicator
A headline salary tells you very little on its own. The indicator converts pay and reported working conditions into a single 0–100 comparison score, so two offers can be weighed against each other honestly.
The TWIX Salary Indicator is an indicative comparison based on the pay and working conditions reported by the employer. It is not legal advice and does not assess compliance with Korean labour law.

What goes into the score
- · Gross monthly salary
- · Scheduled hours per day, and how many of those are contact/teaching hours
- · Working days per week
- · Paid vacation days above or below a typical allowance
- · Housing provided or housing allowance
- · Airfare, severance and insurance treatment
Teaching hours are weighted more heavily than office hours, because contact time is the demanding part of the day. Benefits are converted into an indicative monthly value and the total is normalised against a reference schedule of 9 hours per day, 5 days per week.
Thresholds and weights are configuration, not fixed rules. They are reviewed as the market moves, and each listing stores the score version it was calculated with.
The scale
The indicator reflects only what the employer reported. It cannot detect unpaid overtime, contract terms not disclosed in the listing, or workplace culture. Always read the full contract before accepting an offer.
