What the comparison actually measures
The question is whether a comparable pattern of spending would face a different price level in St. Louis and Tucson. The overall indices are 95.088 and 96.896, respectively, on a scale where the national reference is 100. Their ratio matters more than subtracting their point values. In this article, the percentage comparison always identifies the starting city, so readers moving in either direction can interpret the result without accidentally reversing the denominator. Source: BEA data and methodology.
The statistical areas are St. Louis, MO IL and Tucson, AZ. Their CBSA identifiers are 41180 and 46060. These are metro areas, not just municipal boundaries. A central apartment, a suburban home and a location farther from the employment destination can have very different asking prices within the same statistical area. Use the benchmark to decide what to investigate, then use actual offers to decide what to sign.
The five price comparisons
| 2024 category | St. Louis | Tucson | Tucson relative to St. Louis |
|---|---|---|---|
| Overall prices | 95.088 | 96.896 | 1.9% higher |
| Housing services | 79.024 | 91.765 | 16.1% higher |
| Utilities | 69.921 | 89.521 | 28.0% higher |
| Goods | 99.996 | 96.237 | 3.8% lower |
| Other services | 98.642 | 99.838 | 1.2% higher |
The tradeoff hidden inside the headline
St. Louis has lower indices for housing services, utilities, other services, while Tucson has lower indices for goods. This is a genuine split in the category results. A household concentrated in the categories favoring the more expensive overall metro could reach a different personal conclusion from the headline.
The widest relative gap is 28.0% in utilities, compared with 1.2% in other services, the narrowest component difference. That ordering tells you where to spend research time. Collect evidence first for the category with the largest gap and a meaningful share of your own spending. The widest percentage is not automatically the largest dollar contribution because the amount a household spends in that category can be much smaller.
Housing: compare the lease before assuming the saving
The housing services index is 79.024 for St. Louis and 91.765 for Tucson. In the direction from St. Louis to Tucson, the relative housing level is 16.1% higher. For an illustration only, a $1,500 housing services expenditure in St. Louis scales to $1,742 in Tucson. That calculation is a way to see the relative magnitude; it is not a claim that either amount will rent a particular apartment. Source: BEA data and methodology.
A practical shortlist needs comparable bedroom counts, lease dates and included services. Request written monthly quotes for at least three plausible homes in each city. Keep mandatory charges, parking and separately billed utilities in their own columns. If the Tucson candidate includes an expense that the St. Louis candidate bills separately, add that expense before comparing totals. The cheaper advertised rent can otherwise conceal a higher usable housing budget. This step also prevents an unusually small or distant property from being mistaken for the typical city experience.
Utilities: the building can change the result
Utilities measure a different cost component from housing services. Their indices are 69.921 in St. Louis and 89.521 in Tucson, a 28.0% higher level in Tucson relative to St. Louis. A hypothetical $200 utility expenditure becomes $256 under that ratio. Do not use the housing ratio to scale utility bills or treat the utility percentage as a forecast of consumption. Building size, equipment, occupancy and the allocation of bills still require property evidence.
For this pair, compare the direction of the utility gap with the housing gap before deciding whether the two signals reinforce each other. They point in the same direction. Ask for available bills covering a full year and confirm which services the tenant pays. A single mild month can hide the cash needed during a peak month. Keep a separate line for deposits and activation charges because those affect the amount needed to move even though they are not a recurring monthly price comparison.
Goods and services: do not turn one index into a shopping quote
The goods figures are 99.996 for St. Louis and 96.237 for Tucson. The other services figures are 98.642 and 99.838. In the direction to Tucson, those differences are 3.8% lower and 1.2% higher. These broad groups help explain why a housing advantage does not necessarily translate into the same advantage for every part of daily life. They do not provide standalone estimates for groceries, childcare, healthcare or transport. Source: BEA data and methodology.
Build a small repeat purchase list using the products and services you actually use. Compare equivalent quantities, delivery terms and payment intervals. For a household with substantial service spending, the other services ratio may deserve more attention than an occasional furniture purchase. For someone furnishing a new home, the first month can look quite different from a settled month. Keep those periods separate so that temporary purchases do not become a permanent explanation of the St. Louis versus Tucson cost difference.
A monthly budget in both directions
Starting with $3,000 of illustrative monthly consumption in St. Louis, multiplying by 96.896 divided by 95.088 gives approximately $3,057 in Tucson. The monthly difference is $57, or $685 over twelve months if the same assumptions are held constant. These amounts describe a price level exercise. They are not an estimate of take home pay, an actual family budget or a prediction of expenses after moving.
The reverse exercise starts with $3,000 in Tucson and gives $2,944 in St. Louis. Reversing the calculation changes the percentage because the base changes. That is why a statement that one place is a certain percentage more expensive cannot be reused unchanged to describe how much cheaper the other place is. Readers should start from their own city and keep savings, debt repayments and income tax outside the consumption amount being scaled.
| Starting monthly consumption | St. Louis to Tucson | Tucson to St. Louis |
|---|---|---|
| $2,500 | $2,548 | $2,453 |
| $3,000 | $3,057 | $2,944 |
| $4,500 | $4,586 | $4,416 |
| $6,000 | $6,114 | $5,888 |
Two households can read these cities differently
Consider two deliberately hypothetical spending mixes in St. Louis. The first assigns 50% to housing, 10% to utilities, 20% to goods and 20% to other services. The second assigns 25%, 5%, 30% and 40%, respectively. Applying each category ratio separately to a $3,000 starting amount produces $3,311 for the first household in Tucson and $3,144 for the second. The $167 spread comes entirely from changing the assumed spending mix.
These are sensitivity scenarios created by Homzora, not household budgets published by BEA. They do not reproduce the official aggregation and should not replace the overall series. Their purpose is to show why St. Louis and Tucson can look different to people with different needs. A household should enter its actual category shares and then replace modeled amounts with written quotes when possible. Any proposed saving that disappears after a small change in the housing or service share deserves additional checking before it becomes the reason for a move.
Where the modeled monthly difference comes from
| Category | St. Louis assumed spend | Tucson modeled equivalent | Monthly change |
|---|---|---|---|
| Housing services | $1,500 | $1,742 | $242 increase |
| Utilities | $300 | $384 | $84 increase |
| Goods | $600 | $577 | $23 decrease |
| Other services | $600 | $607 | $7 increase |
In the housing concentrated scenario, housing services contributes the largest absolute dollar change: $242 per month. The combined change across the four categories is a $311 increase moving from St. Louis to Tucson. Individual rounded rows can differ slightly from the rounded total. This breakdown is more useful than applying the largest percentage gap to the entire budget, because it keeps each assumed spending amount attached to its own price category.
What to check on the St. Louis side
The St. Louis statistical area includes Missouri and Illinois. Keep the state and municipality attached to each address throughout the comparison. The metro price level should not erase the distinction between the residential location and the workplace on the other side of the state line.
Test the complete Metro Transit itinerary and keep parking or transfer costs attached to the relevant address rather than the metro average. Start with Metro Transit official travel information. The link is a research resource, not a claim that the agency serves the entire BEA metro. Record the weekday departure, required arrival, return time and any weekend trip. Then compare those results with the Tucson candidate. A route that works for one person at one time is not automatically a workable household transport plan.
What to check on the Tucson side
The Tucson metro average is useful for a broad price comparison, while the property decision still depends on the exact address and utility responsibility. Ask how cooling and other utilities are billed and examine available annual bill history. Transit access should be tested against the actual schedule rather than inferred from a nearby stop.
Check Sun Tran itineraries for the weekday and weekend journeys you need and ask each property for its utility billing arrangement. Start with Sun Tran official travel information. The link is a research resource, not a claim that the agency serves the entire BEA metro. Record the weekday departure, required arrival, return time and any weekend trip. Then compare those results with the St. Louis candidate. A route that works for one person at one time is not automatically a workable household transport plan.
How the relative gap changed from 2023 to 2024
In the same source archive, the 2023 overall values were 94.973 for St. Louis and 94.932 for Tucson. That put Tucson 0.0% lower relative to St. Louis. The 2024 comparison is 1.9% higher, so the absolute relative gap widened. Both years come from the retained BEA data vintage. This is a comparison of relative positions across places, not a calculation of either city’s inflation rate.
The distinction matters when someone asks whether St. Louis is becoming expensive. A regional parity index is measured against a national reference for each year; a change in that relative index does not by itself establish how much local dollar prices changed. Use current property quotes to update the household decision. Do not describe the 2024 figures as measured 2026 prices or assume that a short historical movement will continue after the date of publication. Source: BEA data and methodology.
Moving costs and the time needed to recover them
For a household spending $3,000 in Tucson, the overall ratio suggests $2,944 in St. Louis. The modeled difference is $56 monthly. If a move cost an assumed $3,000, dividing that cost by the modeled monthly difference gives about 53.6 months to recover it. This is only a screening exercise: actual moving quotes, lease overlap and changed commuting costs could extend the recovery period or remove the saving.
Prepare a move calendar before booking transport. Identify the final day of access in Tucson, the first day of access in St. Louis, the delivery window and any period when belongings need temporary storage. For a move in the opposite direction, the same calendar remains useful even though the headline price saving disappears. Get separate quotes for handling, storage and retrieval so that an introductory monthly storage price is not mistaken for the full cost of bridging the two leases.
A decision rule for this particular pair
St. Louis is the starting point for a household whose primary goal is a lower broad consumption price level. However, the strongest component contrast is utilities, not necessarily the category taking the largest share of that household’s budget. Tucson can still be the better personal choice if an actual housing offer, a workable commute, employer benefits or household support offsets the quoted cost difference. None of those offsets is measured by the five indices in this article.
Write down the conditions that would change your choice before committing. For example, compare the total monthly amount for the actual St. Louis property with the actual Tucson property after adding the recurring expenses each excludes. Then compare cash needed before moving and the financial room left after the move. Keep preferences such as proximity to family separate from measured costs, but do not pretend those preferences have no value. The useful outcome is a transparent decision based on your addresses and spending, not a universal winner.
Questions readers often ask
Can these numbers tell me what salary I need in Tucson? No. They can scale an illustrative consumption amount from St. Louis, but gross salary requires separate information about taxes, benefits, savings and household obligations. Can I estimate a mortgage by applying the housing ratio? No. Housing services are not home sale prices or mortgage quotes. Can a cheaper metro still have a more expensive apartment? Yes. The source is a regional benchmark; a particular listing can differ substantially from that benchmark.
Where should I start if I am undecided? Open the interactive comparison for St. Louis and Tucson, then collect address specific evidence for the largest expenses. Use the St. Louis data hub and Tucson data hub for further local research. Revisit the worksheet when a lease quote changes or a new source release becomes available. A dated comparison should remain transparent about what it knows and what still needs verification.
