[Book a Call →](https://lp.lonelyentrepreneur.com/meetings/victoria-sherman/sidekick-call) Every advisor tells you to keep three to six months of expenses in the bank. The largest dataset ever built on small-business cash says almost nobody does. Here is the number you are actually being measured against. Quick Answer **Quick answer:** The median small business holds **27 days** of cash buffer — the number of days it could cover normal outflows if every dollar of income stopped tomorrow. A quarter of small businesses hold **fewer than 13 days**. A quarter hold **more than 62**. The standard advice of three to six months of expenses is a target, not a description: half of all small businesses are sitting below one month. If you are at four or five weeks, you are not failing — you are average. That is exactly why the number is worth knowing. The 30-second version - Median cash buffer across 597,000 small businesses: 27 days (JPMorgan Chase Institute). - Bottom quarter: under 13 days. Top quarter: over 62 days. The spread is enormous. - Restaurants sit at 16 days; real estate firms at 47. Your industry sets your baseline. - Labor-intensive businesses hold 23 days; capital-intensive ones hold 38. - 94% of employer firms reported a financial challenge last year, and 54% covered it out of the owner’s own pocket (Federal Reserve). - Do not benchmark to the advice. Benchmark to your industry, then buy days deliberately. ## Twenty-seven days is the real benchmark There is a number every entrepreneur has heard and almost nobody has measured: keep three to six months of operating expenses in reserve. It is good advice. It is also a target that half the small businesses in America are nowhere near, and pretending otherwise does founders no favors. The JPMorgan Chase Institute built a dataset from more than 470 million transactions across 597,000 small businesses and asked a simple question — if the money stopped coming in today, how many days could this business keep paying out? They call it **cash buffer days**. The median answer was **27**. Not six months. Not three. Under one.

The 90-day column is the conventional three-month rule of thumb, shown for scale only — it is not a JPMorgan Chase Institute figure. Look at the shape of that chart rather than any single bar. The distance between the bottom quartile and the top quartile is nearly five times over. This is not a sector where everyone clusters around a healthy average — it is a sector where some businesses have real room and a great many have almost none, and the two groups can look identical from the outside. ## Your industry has already set your starting line Before you judge your own number, find your row. The variation across industries is not noise and it is not a measure of how well anyone is run — it tracks how much cash a business model has to keep moving through it. A restaurant turns over inventory and payroll constantly. A real estate firm does not.

If you run a restaurant at 20 days, you are ahead of your peers. If you run a professional services firm at 20 days, you are behind them. Same number, opposite verdict. This is the single most common mistake founders make with any benchmark — they compare themselves to the national figure instead of the one that describes their own business model. > Twenty days of cash is a strong position for a restaurant and a warning light for a consultancy. The number means nothing until you know which row you are in. ## What actually drives the number The Institute found two characteristics that explain most of the spread, and neither of them is discipline. Labor-intensive businesses hold fewer days than capital-intensive ones. Low-wage industries hold fewer days than high-wage ones. Payroll is the most relentless outflow a small business has, and the more of your cost base is people, the faster your buffer drains. The Data Where the buffer goes: two structural splits Labor-intensive businesses 23 days Payroll-heavy cost base — the outflow never pauses, so the cushion stays thin Capital-intensive businesses 38 days More cost sits in assets already paid for, so cash sits longer in the account Source: JPMorgan Chase Institute, “Cash is King: Flows, Balances, and Buffer Days” — 470 million transactions across 597,000 small businesses. The same pattern shows up on wages: businesses in low-wage industries hold a median of **19 days**, while those in high-wage industries hold **31**. That is a twelve-day gap created by the structure of the business, not by the judgment of the owner. Knowing which side of it you are on tells you how much margin for error you are actually operating with. ## The consequence nobody puts in the plan A thin buffer does not usually announce itself as a crisis. It announces itself as the owner writing a personal check. The Federal Reserve’s Small Business Credit Survey found that **94%** of employer firms hit at least one financial challenge in the prior year, **57%** described themselves as in fair or poor financial condition, and among firms with challenges, **54%** reached into the owner’s personal funds to deal with it. That last figure is the one I would put on the wall. More than half the time, the shock absorber in a small business is the founder’s own savings. That is not a financing strategy. It is what happens when the buffer runs out and no one planned for it.

Take your average daily cash balance and divide it by your average daily outflow. That is your buffer, in days, and it takes about ten minutes with a bank statement. Then compare it to your industry’s row above rather than to the six-month rule. From there, days are something you buy — and there are only three ways to buy them. Bring cash in sooner: deposits up front, shorter payment terms, invoices out the day the work is done. Push cash out later: negotiated vendor terms, a line of credit arranged while you do not need it. Or lower the daily outflow itself, which is the slowest lever but the only permanent one. Pick a target that is one industry quartile above where you are, not a target borrowed from a textbook. Moving from 20 days to 30 is a real, reachable quarter of work. Moving from 20 days to 180 is a fantasy that makes people give up in week three. The founders who survive their bad quarter are rarely the ones with six months in the bank — they are the ones who knew their number before the quarter went bad. ## Frequently Asked Questions How many months of cash should a small business have? The conventional guidance is three to six months of operating expenses. The data shows the median small business holds 27 days — under one month (JPMorgan Chase Institute). A practical target is one quartile above your industry median rather than a fixed six-month rule. What are cash buffer days? Cash buffer days are the number of days a business could keep covering its normal cash outflows from its existing balance if all cash inflows stopped. The JPMorgan Chase Institute calculates it as average daily cash balance divided by average daily cash outflows. How much cash does the average small business have? Half of all small businesses hold a buffer of less than one month. A quarter hold fewer than 13 cash buffer days and a quarter hold more than 62, based on 597,000 small businesses studied by the JPMorgan Chase Institute. Which industries hold the least cash? Restaurants hold the fewest at a median of 16 cash buffer days, followed by repair and maintenance at 18 and retail at 19. Real estate holds the most at 47 days. Labor-intensive and low-wage industries consistently hold fewer days than capital-intensive and high-wage ones. What happens when a small business runs short of cash? Most often the owner funds the gap personally. The Federal Reserve's Small Business Credit Survey found 94% of employer firms faced a financial challenge in the prior year and 54% of those firms used the owner's personal funds to address it. ![The Lonely Entrepreneur](https://lonelyentrepreneur.com/wp-content/uploads/2024/01/TLE_Logo_mobile-490W-26-26.png) Published by **The Lonely Entrepreneur** — the community and coaching platform for entrepreneurs who are building alone.
