Disclosed is a method for quantifying the furan concentration of a degraded state of a transformer that is efficiently managed in the field. The method for quantifying the furan concentration comprises the following steps of: mixing a color developing reagent into an extraction solution for extracting furan from an insulating oil sample to react, and measuring the color developing degree of the extraction solution; and a step for quantifying the furan concentration by correcting the degree of color development of the extraction solution on the basis of the correlation between the precision analysis and the simple analysis. At the moment, the precise analysis can be analysis in which a quantitative value is obtained through chromatographic separation by using high performance liquid chromatography (HPLC) carried out in a laboratory in order to analyze the furan compound in the transformer insulating oil, and the simple analysis can be analysis in which a chromatic value of an actual transformer sample is obtai
