Fees are small. The habits behind them are not.
If cash withdrawals are how the budget gets away from you, a written plan fixes more than a fee refund.

Frequently asked questions
Is there a national ATM database?
No public one. This page lists FDIC-registered branch locations, which is where in-network machines are normally sited, and does not claim to list every cash machine.
How much does an out-of-network ATM cost?
Typically a surcharge from the machine operator plus a separate fee from your own bank, so a small withdrawal can cost several percent.
How to read the atm in San Marcos numbers
Every figure on this page for San Marcos, TX is a median, not an average, which matters more than it sounds.
A median is the midpoint: half of the local market 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. Locations on record of 16 and institutions represented of 13.
Use them to frame picking a branch or an institution to bank with rather than to settle it. Your circumstances — credit, timing, the specific offer in front of you — move the outcome more than the local midpoint does.
Why the spread around San Marcos, TX matters
Context does most of the work here. A number is only high or low next to something else, so we publish San Marcos, TX and how it sits inside Texas against a wider benchmark on the same measure. State of Texas.
Gaps of a few percent are noise. Gaps of twenty or thirty percent are structural, and they usually trace back to something concrete: the mix of housing stock, how many households are renting rather than owning, the local employer base, or how far the nearest metro area is.
Read the measures as a set. Income on its own says little; income next to housing cost and next to what similar households pay elsewhere says a great deal.
Putting San Marcos, TX next to the alternatives
Comparison is the fastest way to tell a genuinely unusual local market from an ordinary one. We benchmark San Marcos, TX against Texas 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.
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 local market, and inventing one would be worse than showing less.
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 picking a branch or an institution to bank with for the first time or the fifth.
- Verify the branch is still open and staffed before you travel; registers lag closures by a quarter or more.
- Check whether deposit insurance covers your full balance, and how joint accounts change that limit.
- 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.
- 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.
Questions people ask about San Marcos, TX
How current is the atm in San Marcos data?
The figures come from the most recent release of the FDIC office file and the NCUA credit union branch file, 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 San Marcos, TX?
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; federal branch and office registers publish several near-identical measures with meaningfully different scopes.
Can I use this for picking a branch or an institution to bank with?
As a benchmark, yes — it tells you whether an offer or an asking price is normal for this local market. As a substitute for your own quote or estimate, no. Locations on record of 16.
How we built this page
The page is assembled from federal branch and office registers, specifically the FDIC office file and the NCUA credit union branch file. 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 local market.
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.
