Bank Profile: Turtle Mountain State Bank Reviews

Reading the Turtle Mountain State Bank reviews data on this page

Start with one distinction: what we publish for Turtle Mountain State Bank are medians, not averages.

A median is the midpoint: half of the institution sits above it and half below. Averages get dragged around by a handful of extreme values — one very expensive property, one unusually large loan, one graduate earning far more than their classmates — so a median is the safer number to plan against. Total assets of $114 million and branch count of 1.

Treat these as a baseline for opening a savings, checking or CD account, not a quote. Your own position depends on details no dataset holds: credit history, the exact street, the specific product on offer this week.

What these numbers mean for savers comparing where to keep their money

Context does most of the work here. A number is only high or low next to something else, so we publish Turtle Mountain State Bank and how it sits inside North Dakota against a wider benchmark on the same measure. Headquarters of Belcourt, North Dakota.

A difference of a few percent is inside the survey's own margin of error. A difference of a quarter or more is real, and it normally reflects the housing mix, the dominant local industries, or how much of the population is retired rather than working.

The useful habit is to pair every figure with the cost it has to cover. Income against rent, loan size against income, price against what the same money buys one county over.

Five checks worth running first

None of this needs a spreadsheet. It needs the discipline of checking the same handful of things every time, whether you are opening a savings, checking or CD account for the first time or the fifth.

• Confirm the rate you were quoted is the standard rate, not a promotional tier that resets after a few months.
• Check the minimum balance and the monthly maintenance fee, which can quietly outweigh the interest earned.
• Ask what the number looks like in a bad year, not an average one, and make sure the plan still holds.
• Write down the monthly number you can genuinely cover, not the maximum a lender or admissions office says you qualify for.
• Compare at least three offers. Pricing on the same product varies more between providers than most people expect, and the gap is yours to keep.
• Check the fee schedule and the fine print, not the headline rate — that is where the real cost usually hides.

How Turtle Mountain State Bank compares

Comparison is the fastest way to tell a genuinely unusual institution from an ordinary one. We benchmark Turtle Mountain State Bank against North Dakota and against the national picture on the same definitions, in the same period, so the difference you see is a real difference rather than an artefact of two datasets disagreeing.

Most contradictory statistics you meet online are definition mismatches rather than errors. Gross versus net, occupied versus advertised, applications versus originations: each pair produces a different headline from the same underlying reality.

Any measure the source flags as unreliable is dropped rather than smoothed. That is why some pages carry fewer figures than others: the institution itself is thinly sampled.

Questions people ask about Turtle Mountain State Bank

How we built this page

The page is assembled from quarterly regulatory filings, specifically the FDIC Institution Directory and Summary of Deposits (2026-09-16). Nothing here is modelled from a proprietary black box: every figure traces to a published record, and where we derive a ratio we show both inputs so the arithmetic can be checked.

The limits are the usual three: sampling error grows as geography shrinks, published data always trails reality by months or years, and a midpoint says nothing about the extremes at either end of the institution.

Where a source revises a figure, the revised value replaces the old one rather than sitting alongside it, so the page always reflects the current official position. If you spot a number that looks wrong, it is worth telling us — corrections get made against the source record, not by guesswork.
