The typical small business has 27 days of cash
How big your reserve should be, where to keep it and how to build it.
Business savings are what keep the doors open when sales dip, a customer pays late or the walk-in freezer fails, and most small firms have far less than they think.
The JPMorgan Chase Institute studied the bank accounts of roughly 600,000 small businesses and measured “cash buffer days”: how long a business could keep paying its bills from cash on hand if money stopped coming in. The median business had 27 days. One in four had 13 days or fewer. A typical small restaurant had 16 days, while real estate businesses held 47.

When money runs short, owners usually reach into their own pockets. In the Federal Reserve’s 2025 Small Business Credit Survey, using the owner’s personal funds and drawing down cash reserves were among the most common responses to financial challenges, along with raising prices and cutting costs. More than a third of firms with challenges took on debt.
How much should a small business save?
A common target is three to six months of operating expenses. Three months suits businesses with steady, recurring revenue and low fixed costs. Six months or more suits seasonal businesses, firms with a few large customers, and any business with a big payroll or long payment terms.
Start with your real numbers. Add up a typical month of rent, payroll, loan payments, insurance, utilities, software and supplies. Then compare that with the cash you hold today.

Three buckets, not one
Owners who save successfully usually split business savings into separate accounts, so each dollar has a job:
- Operating reserve: the three to six months of expenses above, used only for true emergencies or gaps in revenue.
- Tax account: a set percentage of every deposit for income, payroll and sales taxes. Owners who expect to owe $1,000 or more generally pay estimated taxes four times a year.
- Opportunity fund: money for planned equipment, a second location or a large order, so growth does not drain the reserve.
Where to keep business savings
Reserve money has two jobs: be safe and be available within days. That rules out stocks and most long-term investments. Common choices:
Where small businesses keep cash reserves
| Access | Typical return | Safety | |
|---|---|---|---|
| Business savings account | Same or next day | Low to moderate | FDIC or NCUA insured to $250,000 |
| Business money market account | Same or next day, may limit checks | Moderate | FDIC or NCUA insured to $250,000 |
| Certificates of deposit (CDs) | Locked for a term; penalty to withdraw early | Moderate, fixed | FDIC or NCUA insured to $250,000 |
| U.S. Treasury bills | Matures in 4 to 52 weeks; can be sold | Market rate | Backed by the U.S. government |
| Insured cash sweep | Same or next day | Varies | Spreads deposits across banks for more coverage |
Deposit insurance covers $250,000 per depositor, per bank, per ownership category. If your reserve grows past that, split it across banks, use a sweep program or move part into Treasury bills.
How to build a reserve, step by step
Your business savings plan
- Know your monthly burnTotal your fixed and variable costs for the last three to six months and take the average.
- Set a first goalStart with one month of expenses. It is reachable and immediately useful.
- Automate a transferMove a fixed percentage of every deposit, such as 3% to 5%, into savings on the day it arrives.
- Separate the tax moneySend a set share of each deposit to a tax account so quarterly payments never come out of the reserve.
- Add windfallsPut part of every unusually good month, tax refund or large contract into the reserve.
- Review every quarterRaise the target as expenses grow, and refill the reserve after you use it.
Savings and credit work together
A cash reserve and a business line of credit are not substitutes; they back each other up. Cash covers short, predictable gaps at no cost. A line of credit covers larger or longer gaps, but it costs interest and a bank can reduce it when your business is struggling, exactly when you need it most. Lenders also look at your balances: steady savings show a business that manages money well.
One more habit makes a difference: name each account for its job, such as “Payroll reserve” or “Q3 taxes,” so every balance tells you at a glance whether you are on track. Many banks let you rename accounts in their app. Review the balances on the first business day of each month, alongside your bookkeeping, and adjust the automatic transfer if expenses have grown.
Why small businesses struggle to save
Most owners do not skip saving on purpose. Cash gets reinvested in inventory, equipment and hiring because growth feels more urgent than a reserve. Others keep extra cash in the operating account, where it quietly gets spent. Separating the reserve into its own account, ideally at a different bank or at least without a debit card, makes the money harder to spend by accident.
Seasonality makes the problem worse. A retailer may earn a third of its revenue in the last quarter, a landscaper may slow down every winter and a tax preparer may earn most of its income by April. These businesses need a reserve sized to the slow season, not to an average month. Look at your last two years of monthly revenue to see how deep the low months are.
How much is too much?
Savings can go too far. Cash sitting in a low-yield account while the business pays high-interest debt, or while it turns away profitable work because it lacks equipment, has a cost. Once your reserve reaches your target, direct extra cash to paying down expensive debt, investing in projects with a clear return or paying owners.
Common mistakes
- Saving whatever is left. There is rarely anything left. Save first, by automatic transfer.
- Spending the tax money. Keep it in its own account and treat it as already gone.
- Not refilling the reserve. After an emergency, rebuild the balance before new spending.
- Chasing yield. A reserve exists to be safe and available, not to earn the highest return.
Key terms
- Cash buffer days: how many days of normal outflows your cash on hand could cover with no new revenue.
- Operating expenses: the recurring costs of running the business, such as rent, payroll and utilities.
- Liquidity: how quickly an asset can be turned into cash without losing value.
- Money market account: an insured deposit account that often pays more than savings but may limit transactions.
- Treasury bill: short-term U.S. government debt that matures in one year or less.
The bottom line: know your monthly costs, set a target of three to six months, automate a transfer from every deposit and keep the money safe and separate. A reserve turns a bad month into an inconvenience instead of a crisis.

Frequently asked questions
How much cash should a small business keep in reserve?
A common target is three to six months of operating expenses. Seasonal businesses and those with a few large customers should aim for the high end or more.
Where should a small business keep its emergency fund?
In safe, easy-to-reach places such as an insured business savings or money market account, short-term CDs, or U.S. Treasury bills. Avoid investments that can lose value when you need the cash.
Is business savings insured?
Yes, at FDIC-insured banks and NCUA-insured credit unions, up to $250,000 per depositor, per institution, per ownership category.
Should I save or pay down debt first?
Build at least one month of expenses in cash first, then split extra cash between savings and paying down the most expensive debt.
How do I start saving when cash is tight?
Start small and automatic. A transfer of even 1% to 3% of each deposit builds the habit, and you can raise the percentage as margins improve.
