When comparing loans in South Dakota, your credit score is the single biggest factor determining the rates you are offered. With a state average FICO of 736 and a median household income of $61,898, most South Dakota residents qualify for mainstream lending products — but the rate difference between good and excellent credit can be substantial.
South Dakota consistently ranks in the top 5 for credit scores. Like its northern neighbor, the state benefits from a stable agricultural and credit-services economy, low unemployment, and a conservative financial culture.
The average South Dakota resident carries $5,155 in credit card debt, $22,500 in auto debt, and $27,200 in student loans. Adding a new loan increases your total debt obligations — use the calculator above to ensure the combined payment fits within a back-end DTI below 43% on your income of approximately $61,898.
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.
