Two different rates matter here, and they are easy to confuse. The effective rate of 12.7% is the average cost of every unit of pay across the whole salary. The marginal rate is what the next slice of pay is charged at — around 19.2% on the next ₩1,000 of gross. The marginal rate is the higher of the two, because the lower bands have already been taxed at less. It is the marginal rate, not the effective rate, that decides what a pay rise is actually worth.
Every figure on this page comes from the same calculation engine that runs the calculator itself, so this hub and the individual salary pages it links to cannot disagree with one another.
