Debt-to-Income Ratios for South Dakota Residents

Debt-to-income (DTI) ratio is one of the most critical factors lenders evaluate. For South Dakota, with a median household income of $61,898 (approximately $5,158/month), understanding your DTI is key to qualifying for mortgages, auto loans, and personal loans.

South Dakota's median income is near the national average. The state has no personal income tax, which provides a meaningful boost to effective household purchasing power relative to states with high income taxes.

South Dakota DTI Benchmarks

• Front-end DTI (housing only): South Dakota's average mortgage DTI is 28%. Lenders typically want this below 28–31%.
• Back-end DTI (all debts): Most conventional lenders cap this at 43–50%. With South Dakota's average debts totaling $76,000, managing all obligations within this range requires careful budgeting.
• Average credit card payment: Approximately 103 monthly minimum on the state average balance

South Dakota's highly affordable housing market produces some of the lowest mortgage DTI ratios in the country. Sioux Falls, the largest city, consistently ranks among the most affordable metros nationally.
