Salt Lake City carries a composite cost-of-living index of 108, meaning typical costs run about 8% above the US average of 100. Housing is the biggest driver, while groceries, utilities, and healthcare sit closer to the national norm. This free tool benchmarks SLC against the US average and any comparison city, and converts your income into purchasing power.
How it works
The index uses the US average as a baseline of 100:
- Purchasing power in average-cost dollars =
income * (100 / 108). Because SLC is above average, your dollars buy slightly less than the national norm. - Equivalent income needed in a comparison city =
income * (target_index / 108). This scales your SLC income to keep the same standard of living elsewhere.
A city with a higher index requires more income to match your lifestyle; a lower index requires less.
Category breakdown (SLC, US avg = 100)
- Housing: 118 (above average — the main driver)
- Groceries: 100 (about average)
- Transportation: 102 (slightly above average)
- Utilities: 96 (below average)
- Healthcare: 99 (about average)
Example
Earning $70,000 in SLC, your purchasing power in average-cost dollars is 70,000 * (100/108) ≈ $64,815. To match that lifestyle in a city at index 130, you would need 70,000 * (130/108) ≈ $84,259.
Why SLC sits above the national average
Salt Lake City’s composite index of approximately 108 is primarily driven by housing, which has risen sharply since around 2020. The broader Wasatch Front — the metro corridor running from Ogden through SLC to Provo — saw substantial in-migration as the “Silicon Slopes” tech cluster grew, attracting workers from more expensive coastal cities. That demand pushed rents and home prices above historical Utah norms.
Outside of housing, SLC remains relatively affordable by major US city standards. Groceries and utilities hover near the national average. Healthcare is close to typical. Transportation is modestly above average partly due to car dependency: while UTA runs an expanding light rail and bus network, suburban Salt Lake requires a car for many trips, and fuel and insurance costs affect the index.
What the index does not capture
Cost-of-living indices measure consumer prices, not total economic conditions. A few important factors sit outside the index:
- Utah income tax: Utah applies a flat income tax rate. Factor this separately when comparing take-home pay between states.
- Neighborhood variation: Costs vary significantly within the metro. Sugar House and downtown SLC are more expensive than West Valley City or Midvale. Nearby Utah County (Provo, Orem) historically carries a lower housing index than SLC proper.
- Sales tax: Utah’s combined state and local sales tax varies by city and county. Salt Lake City’s combined rate is higher than the state base rate.
- Quality differences: The index assumes comparable goods and services across locations. A $1,500 apartment in SLC may be larger or smaller than an equivalently priced unit in another city, which the index does not capture.
Moving-decision use case
If you are currently earning a given salary in a city with a known index and considering a move to SLC (index 108), you can estimate what salary you would need to maintain your current standard of living:
required SLC salary = current salary × (108 / your current city index)
For example, moving from Austin (index roughly 94) to SLC on a $75,000 salary: 75,000 × (108 / 94) ≈ $86,170 needed to match the same lifestyle.
Notes
Cost-of-living indices are survey estimates that shift over time and vary by source and neighborhood. They cover consumer prices, not income taxes — factor Utah’s flat income tax separately. Use these figures for directional comparison. All math runs locally in your browser.
