Maybe you've been looking at Idaho Falls and someone told you Rexburg is cheaper. Maybe BYU-Idaho is bringing you here and you're trying to figure out what a real household budget looks like in a college town. Either way, the first thing to understand about Rexburg is that its cost profile is unusual for eastern Idaho: a city of roughly 41,000 people, anchored by a major university, sitting along US-20 about 30 minutes north of Idaho Falls — and running noticeably below the national average on nearly every cost category except one: housing pressure from student-driven rental demand.
The economic backbone is Brigham Young University-Idaho, which employs thousands and shapes the rental market more than any other single factor. The regional employment picture fills out from there, but it's the university enrollment that determines what landlords charge and how quickly available units disappear. That dynamic cuts both ways: it keeps certain entry-level prices accessible for buyers, while pushing two-bedroom rents higher than the surrounding rural counties might suggest.
Overall, Rexburg's total cost of living scores roughly 6.6% below the U.S. average and meaningfully below the Idaho statewide average, according to 2026 BestPlaces index data. Groceries run almost exactly at the national average. Natural gas — critical for eastern Idaho winters — costs dramatically less here than the national average. Property taxes are among the lowest in an already low-tax state. Where the numbers get more complicated is the income-to-housing ratio: the median household income in Rexburg sits at $50,617, which is modest against even a mid-market home price, and that tension shapes every major financial decision you'll make here.
Whether you're renting a place near campus while you decide, or ready to buy in one of the newer subdivisions on the city's edges, the sections below break down Rexburg's housing costs, everyday expenses, how this city stacks up against nearby markets, and what Idaho's tax structure actually means for your bottom line.
What It Really Costs to Live in Rexburg
The headline number is $403,386 — the Zillow Home Value Index for Rexburg as of May 2026. That figure sits noticeably below what you'd pay in Driggs or a comparable college town out of state, and it's close to the Idaho statewide median, but it's a real stretch against the local median household income of $50,617. The math matters: Rexburg is affordable compared to the national map, but not cheap relative to what most people actually earn here.
What drives the number is a combination of BYU-Idaho enrollment pressure, limited developable land in the US-20 corridor, and a wave of in-migration from higher-cost western states that ran hot through 2022 and 2023. Prices have moderated since that peak, and a 50-acre mixed-use development called Madison Commons near the Main Street/US-20 interchange is adding roughly 250 multi-family units plus retail — which should ease some rental-side pressure over the next few years.
Non-housing costs are genuinely low. Natural gas runs roughly 51% below the national average, which matters enormously in a city that sees hard winters. Electricity from the regional utility was running approximately 12.70 cents per kilowatt-hour as of April 2026 — up about 7% year-over-year, but still in a manageable range. Groceries track almost exactly at the national average. Transportation is car-dependent, but pump prices in the Rexburg area have historically been in the lower third of the national range. Add it all up and the city's overall cost index comes in roughly 6.6% below the U.S. average — a genuine advantage, as long as your housing payment stays proportional.
Housing: Rent vs Buy in Rexburg
The Buying Side
The city-wide median sits at $403,386 (Zillow Home Value Index, May 2026). Entry-level homes — older construction, smaller footprints, typically farther from the BYU-Idaho campus — start closer to the low-to-mid $300,000s. Newer construction in the subdivisions being added on Rexburg's outskirts pushes well past the median. For neighborhood-level price breakdowns, see the best neighborhoods guide.
The effective property tax rate in Madison County is approximately 0.56% — well below the national median of around 0.89%. On a home at the city-wide median, that rate is modest. Idaho also offers a homeowner's exemption that reduces the taxable assessed value, so the real-world annual tax bill tends to land lower than buyers from high-tax states expect. Use the mortgage calculator below for a complete monthly payment estimate; this section intentionally covers rate, not dollar totals.
The Renting Side
Two-bedroom apartments in Rexburg were running approximately $1,090–$1,200 per month as of August 2026, with one-bedrooms averaging around $900. Those figures are well below national medians, but they reflect a market that moves fast at the start of each academic semester. The Madison Commons development will add new inventory over the next few years, but for now, the window between listing and lease-signing near campus can be very short.
Rent vs Buy: When Each Makes Sense
Renting makes more sense if your timeline in Rexburg is under three years, or if you're still working out which part of the city fits your household. The carrying costs of ownership are reasonable — especially given the low property tax rate — but buying in a college-town market does expose you to enrollment-cycle volatility when you eventually sell. Buyers with a five-plus-year horizon, particularly those working at the university, tend to come out ahead once they clear the transaction costs.
Everyday Costs Beyond Housing in Rexburg
Utilities are the clearest budget win in Rexburg. Natural gas averages far below national rates — roughly $8.91 per thousand cubic feet as of April 2026, compared to a national average near $18.17 for the same month. That gap is significant in a city that regularly sees temperatures below zero from November through February. Electricity at approximately 12.70 cents per kilowatt-hour is moderate; combined with natural gas heating, most households run lower annual energy costs than in comparable-climate cities.
Groceries are essentially at the national average — no meaningful discount, but no premium either. The main grocery options in Rexburg are a Walmart Supercenter and a WinCo Foods, which both skew toward value pricing. Gas runs in the mid-$3 range; eastern Idaho pump prices in late 2025 were directionally consistent with the low-$3 range seen across the broader region. Phone and internet options are limited compared to a larger metro — fiber availability depends heavily on your address, and some areas are still on cable or fixed wireless.

| Utilities (electric + gas) | $130–$185 | Varies significantly by season; winter gas bills are the largest driver. |
| Groceries | $350–$500 | Index essentially at national average; WinCo and Walmart Supercenter are main options. |
| Transportation & Gas | $150–$250 | Car-dependent city; eastern Idaho gas prices have tracked in the lower national range. |
| Phone & Internet | $80–$140 | Fiber availability is uneven; some addresses limited to cable or fixed wireless. |
| Misc / Discretionary | $150–$300 | Dining, entertainment, personal care. Rexburg's dining scene is modest; Idaho Falls adds options a short drive away. |

Driggs, driven by Teton Valley resort demand, sits in an entirely different price tier. Idaho Falls offers a broader job market and more retail amenities at a comparable purchase price, which is why the Rexburg-vs-Idaho Falls decision is so common — and so genuinely close.
Taxes & the Bottom Line for Rexburg
State Income Tax
Idaho moved to a flat individual income tax rate of 5.3% effective January 1, 2025, down from the previous 5.695%. That's a meaningful reduction and still competitive with most western states — though not as low as Nevada or Wyoming, which have no state income tax. For a household earning around the local median, the effective Idaho income tax burden is real but moderate.
Sales Tax
Idaho's state sales tax is 6.0%, with a combined state-and-local rate of approximately 6.03% in Rexburg — there is essentially no local add-on. The catch is that Idaho applies sales tax to groceries, which hits lower-income households disproportionately. The partial offset: Idaho offers a Grocery Tax Credit of $155 per person (raised in 2025 from $120), which filers can claim on their state return. Higher-receipt households can also claim up to $250 with documentation. It's not a full exemption, but it's a meaningful cushion.
Property Tax
The effective property tax rate in Madison County is approximately 0.56%, as noted earlier in the housing section. That's well below the national median. Idaho's homeowner's exemption reduces the taxable assessed value on a primary residence, so buyers coming from states like California, Oregon, or Washington are often surprised by how modest the annual property tax obligation feels relative to the home's value.
Who This Budget Works For
Rexburg's cost structure fits households that earn at or above the state median and plan to stay at least four to five years — particularly dual-income families and university employees with stable positions. The home prices referenced above stretch thin against a single income at the local median of $50,617; buyers in that range should model their numbers carefully using current rate inputs rather than assuming last year's payment estimates still hold. Those who find the budget a squeeze often cite the income-to-price ratio and the limited local earning ceiling as the reason they eventually leave — Idaho Falls or even Boise tend to offer more rungs on the career ladder, even if the sticker prices are higher.
Local Expert Takeaway: Rexburg is genuinely cheaper than the national average on nearly every line item except the income-to-housing ratio. Natural gas bills run dramatically below what you'd pay in comparable-climate cities, groceries are essentially flat against national averages, and a 0.56% effective property tax rate means ownership is lighter on the annual tax burden than most buyers expect. The real budget risk is buying at the city-wide median on a single local income — the math gets tight fast. If you're weighing Rexburg against Idaho Falls for a lower purchase price, factor in the additional driving costs before assuming the savings are real. And if the Madison Commons development delivers its 250 units on schedule, the rental market should ease by 2027, which may matter if you're timing a transition from renting to buying.
