What Is the DSR Calculator?

DSR (Debt Service Ratio) is the percentage of your annual income that goes toward repaying all loan principals and interest. It is a key metric lenders use to judge your borrowing capacity in Korea.

How It’s Calculated

• Total Annual Repayment = Sum of all loans’ annual principal + interest payments
• DSR = (Total Annual Repayment ÷ Annual Income) × 100

How to Use This Tool

Enter your annual income and each loan’s annual repayment amount, then set a target DSR threshold (e.g., 40%). The tool instantly shows your actual DSR and whether it meets the threshold.
