These are counts of establishments physically operating in the county, not listings, so they are the supply side a feasibility study measures demand against. County Business Patterns counts private establishments with paid employees in March 2023, while the Quarterly Census of Employment and Wages above counts every unemployment-insured employer, public ones included, as a 2024 annual average, so the two establishment and employment counts differ.

The average approval of $343,045 sits well above the median of $141,400, pulled up by a few larger deals, so the median is the better guide to what a typical borrower here gets. Only 6.8 percent of approvals run on real estate terms, so SBA credit here is mostly working capital and equipment rather than property acquisition.

SBA loan default and charge-off rates in Bonneville County
Do SBA loans in Bonneville County get paid back?
- Loans with a final outcome recorded44
- Paid in full42
- Charged off2
- Charge-off rate on resolved loans4.5 percent
- Status: Cancelled34
- Status: Paid in full42
- Status: Exempt from disclosure167
- Status: Charged off2
- Status: Committed, not yet disbursed18
Of the 44 loans that have reached a final outcome, 4.5 percent were charged off. This is computed only over resolved loans, because a loan still running has not yet succeeded or failed and counting it either way would be wrong.
Compare against the national and state SBA charge-off rates, computed the same way over resolved loans only.

The county's own community in the status book, unincorporated Bonneville County (community 160027), participates in the National Flood Insurance Program and carries no Community Rating System class, so no CRS premium discount applies there. The EPA places Bonneville County in radon zone 2, a predicted average indoor radon screening level from 2 to 4 pCi/L. The zone is a screening prediction for the county and does not substitute for a test at an address. 100.0 percent of the county's listed communities participate in the National Flood Insurance Program, per Federal Emergency Management Agency, NFIP Community Status Book (OpenFEMA), as of 2026-09-26.
