PURPOSE: A credit limit management method and a system thereof are provided to handle the whole loan of a financial institution as a random variable which is changed corresponding to an asset value, thereby finally calculating a credit limit level. CONSTITUTION: An asset value and asset value variability are estimated by a central processing unit(S200). Asset value distribution is determined from the estimated asset value and asset value variability(S300). A credit limit including a proper limit, a maximum limit one, and a maximum limit second is calculated from the asset value distribution(S400). A credit limit level is calculated based on the credit limit(S500).
