What the First Interstate Bank reviews figures actually show
The numbers published here for First Interstate Bank are medians — the midpoint of the distribution rather than the mean.
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 $26 billion and branch count of 240.
They describe the middle of the market, so they are a starting point for opening a savings, checking or CD account and nothing more. Anyone quoting you a number will be pricing your file, not the median.
Why the spread around First Interstate Bank matters
Context does most of the work here. A number is only high or low next to something else, so we publish First Interstate Bank and how it sits inside Montana against a wider benchmark on the same measure. Headquarters of Billings, Montana.
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.
That is why a single figure should never carry a decision on its own. Read two or three measures together — what comes in, what housing costs, what is left — and the picture stops being ambiguous.
What to check before you commit
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.
- 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.
- 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.
How First Interstate Bank compares
Comparison is the fastest way to tell a genuinely unusual institution from an ordinary one. We benchmark First Interstate Bank against Montana 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.
Watch the denominator whenever a comparison surprises you. Whether a rate is calculated on all applications or only completed ones, on every unit or only those on the market, changes the answer more than the local market does.
Where a comparison would mislead, we leave it out instead of filling the gap. A blank means the source did not publish a reliable estimate for that institution, and inventing one would be worse than showing less.
Frequently asked questions about First Interstate Bank
How current is the First Interstate Bank reviews data?
The figures come from the 2026-09-16 release of the FDIC Institution Directory and Summary of Deposits, and we refresh the page when a new one is published. Public datasets run a reporting lag of several months to two years, so the latest available period is not the same as today.
Why does another site show a different number for First Interstate Bank?
Almost always because it is measuring something slightly different, or using an earlier release. Check the definition and the period before assuming one of the two is wrong; quarterly regulatory filings publish several near-identical measures with meaningfully different scopes.
Can I use this for opening a savings, checking or CD account?
As a benchmark, yes — it tells you whether an offer or an asking price is normal for this institution. As a substitute for your own quote or estimate, no. Total assets of $26 billion.
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.
Be aware of what the data cannot do. Small-area estimates are noisier than headline national ones, every source reports on a delay, and no median describes the outliers that people most often remember.
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.
