How This Calculator Works
Calculation methodology and assumptions
This calculator compares purchasing power between locations using cost of living indices. South Dakota's composite cost of living index is 94.1 (100 = national average). The equivalent salary is calculated as: Current Salary × (Target COL / Current COL). The "Equivalent Rent" output instead scales by the MERIC Housing-component index specifically (South Dakota: 88.2) — the composite blends groceries, housing, utilities, transportation, health, and other goods, and using it to scale rent alone would misstate the true housing differential in states where housing moves differently than the blend. The tax-savings figures apply each state's top marginal income tax rate as a flat rate to your current salary; this is a sensitivity check, not a filing estimate, and it overstates the true tax difference for any state with a progressive bracket structure.
Key State Information
South Dakota cost of living index: 94.1 (composite); Housing-component index: 88.2. South Dakota is close to the national average in overall cost. South Dakota's lack of state income tax provides additional savings for residents. Median household income: $76,881 (U.S. Census Bureau, American Community Survey 1-year estimate, table B19013, 2024). Fair Market Rent, 2BR (HUD FY2026, 40th-percentile gross rent — not a median asking rent): $1094/month.
Example Calculation
How does South Dakota's cost of living affect your purchasing power?
If you earn $75,000 in South Dakota with a cost of living index of 94.1 — South Dakota's actual index (100 = national average), your purchasing power is equivalent to roughly $79,702 in an average-cost US city. South Dakota is below the national average, so your dollars stretch further.
Result: The cost of living difference between the most and least expensive states can be enormous — a resident of a low-index state earning $75,000 can have the same purchasing power as someone earning far more in a high-index state like Hawaii or California. Always compare salaries in purchasing power terms, not nominal dollars.
