PROBLEM TO BE SOLVED: To provide a loan-contract repayment condition updating device for automatically updating a loan repayment condition in consideration for preventing an interest-rate variation from causing a substantially heavier repayment burden on a debtor of a variable-interest loan in any phase of increasing and decreasing interest rates.;SOLUTION: A repayment condition is configured to be automatically updated so as not to increase a substantial repayment burden on a debtor at each point in time by setting a part of a contract condition at a time of loan contract as a reference value for re-calculating the repayment condition at an interest rate variation, and changing the reference value to be fixed in re-calculating the repayment condition depending on whether an applied interest rate has increased or decreased since the time of contract. The applied interest rate at the time of contract is compared with an applied-interest rate after the variation (S07). An amount of each repayment is fixed to extend a repayment period if the applied interest rate has increased (S08 through S10). The repayment period is fixed to reduce the amount of each repayment if the applied interest rate has decreased (S11 and S12).;COPYRIGHT: (C)2013,JPO&INPIT
