The 2015 Buffer-Day Baseline
The median small business held 27 cash buffer days in 2015, operating cash balance divided by average daily outflow, according to JPMorgan Chase Institute’s “Cash is King: Flows, Balances, and Buffer Days” report, drawn from 597,000 small businesses and more than 470 million transactions tracked from February through October that year. The distribution around that median was wide: the bottom 25% of firms held 13 buffer days or fewer, while the top 25% held 62 days or more, a range spanning nearly five times over between the thinnest-cushioned quarter of firms and the best-cushioned quarter.
Industry drove much of that spread. Restaurants held the fewest buffer days of any sector measured, just 16, while real estate firms held the most, 47, nearly three times the restaurant figure. A restaurant and a real estate firm holding otherwise identical revenue can sit at opposite ends of the buffer-day distribution purely because of how each industry’s cash cycle is structured.
How Buffer Days Varied by City in 2015
The same 2015 report found buffer days ranging from 21 in Orlando to 34 in San Jose across the metros it analyzed, roughly a 13-day spread between the thinnest- and best-cushioned cities measured. Geography alone, independent of industry mix, was a real driver of how much cash cushion a typical local business carried.
A Sharper, More Recent Snapshot: April 2020
A separate JPMorgan Chase Institute study, “Small Business Cash Liquidity in 25 Metro Areas,” based on 1.4 million small businesses using Chase Business Banking deposit accounts in April 2020, found 50% of small businesses operating with fewer than 15 cash buffer days, and only 40% holding more than 21 days, three weeks of cushion. Roughly half the small businesses measured in that snapshot were running with less than half the median buffer the 2015 report found five years earlier.
Which Metros Ran Thinnest on Cash in 2020
San Francisco, San Jose, Seattle, and Portland ran the highest median buffer in the April 2020 study, 18 days each, while Atlanta and Orlando ran the lowest, 11 days each, San Francisco’s buffer running more than 60% higher than Atlanta or Orlando’s. Five metros crossed the study’s own high-risk threshold, more than 50% of firms holding under 14 buffer days: Atlanta at 54%, Riverside at 53%, Miami and Tampa both at 52%, and San Antonio at 51%.
Why Two Separate Snapshots Do Not Add Up to One Trend Line
The 2015 and April 2020 reports measure related but distinct things, a median buffer-day figure in the first case and a share of firms under a specific-day threshold in the second, drawn from different sample sizes five years apart. No JPMorgan Chase Institute update to either figure has been published since 2020, so this piece presents both years and both metrics separately rather than implying a single continuous trend line the underlying research does not support.
What Thin Cash Buffers Mean for How a Business Uses Financing
A business holding under 15 buffer days, the reported condition for half of small businesses measured in April 2020, is one late invoice, one slow week, or one seasonal dip away from missing payroll or rent. That structural thinness, rather than any single bad month, is the underlying condition MCA underwriting is built to work with, since it evaluates daily card and ACH deposit activity directly instead of the static buffer-day balance-sheet snapshot a traditional bank loan relies on.
Human + AI SDRs qualify merchants over SMS with exactly this cash-flow reality in view, surfacing prospects based on real deposit activity instead of a single-day balance.
The Numbers
Median small business cash buffer, 2015: 27 days, with the bottom 25% of firms at 13 days or fewer and the top 25% at 62 days or more (597,000 businesses, 470M+ transactions, February to October 2015).
