# Days cash on hand and liquidity survival metrics
In 2019, when the pandemic froze elective surgeries almost overnight, the hospitals that survived the first 90 days were not the ones with the biggest revenue. They were the ones with the most cash sitting in the bank. Elective procedures (planned, non-emergency surgeries like knee replacements) are the profit engine of most hospitals, and when they stopped, so did the cash flow. What kept the lights on was the reserve already in hand.
That reserve, measured as days cash on hand, is the single most watched liquidity metric in hospital finance. This lesson shows you how to compute it, how to compute its faster cousin the current ratio, and why the rating agencies draw a hard line around it.
Liquidity is the ability to pay bills that come due soon, using cash or things easily turned into cash. A hospital can be profitable on paper and still fail if it cannot make payroll next month. Nurses, physicians, utilities, and drug suppliers all want paying on schedule.
Hospitals are especially exposed because a large chunk of their revenue is tied up in accounts receivable (money owed by insurers and government payers that has not yet arrived). In the US, Medicare and Medicaid (the federal and state insurance programs for the elderly and low-income) can take weeks to reimburse. That lag makes cash reserves a survival tool, not a luxury.
Days cash on hand (DCOH) answers a blunt question: if all revenue stopped tomorrow, how many days could the hospital keep operating using its liquid resources?
Days Cash on Hand =
(Cash + Short-term investments + Unrestricted long-term investments)
/ (Total annual operating expenses - Depreciation) / 365We subtract depreciation (the accounting spread of an asset's cost over its life) because it is a non-cash expense. No cash leaves the building for it, so it should not count against your daily cash burn.
Imagine a mid-sized US community hospital, Riverside General:
Step 1: Total liquid resources = 40 + 30 + 110 = 180 million USD
Step 2: Cash operating expenses = 500, 35 = 465 million USD
Step 3: Daily cash burn = 465 million / 365 = 1.274 million USD per day
Step 4: DCOH = 180 million / 1.274 million = 141 days
Riverside can run for about 141 days with zero incoming revenue. That number, as we will see, would worry a rating analyst.
Credit rating agencies (firms that grade how likely a borrower is to repay debt) publish medians every year. These drive borrowing costs, because a hospital that issues municipal bonds to fund a new wing pays a higher interest rate if its liquidity looks thin.
Moody's Ratings and S&P Global Ratings are the two dominant agencies in US not-for-profit healthcare. Widely cited industry medians (treat these as approximate and check the current year's report):
So Riverside's 141 days puts it in the caution zone: not a crisis, but below the comfort threshold that top-rated systems maintain.
For a sense of official reporting standards behind these numbers, the US Healthcare Financial Management Association publishes practitioner guidance on liquidity measurement.
European hospital finance does not lean on days cash on hand the same way, and here is the key reason: most European systems are publicly funded. In the UK, NHS (National Health Service) trusts are financed and backstopped by the government, so a private cash cushion is less central to survival. Instead, oversight bodies watch metrics like the cash releasing efficiency targets and statutory break-even duties.
In tax-funded systems (much of the Nordics, the UK, Spain), the "will it survive?" question is answered by government budgets, not by the balance sheet. In more insurance-based systems with private and non-profit hospitals (Germany, France, the Netherlands), liquidity ratios matter more, but there is no single pan-European DCOH benchmark comparable to Moody's US medians. Always specify the country before comparing.

Days cash on hand is thorough but data-hungry. The current ratio is a quicker screen you can pull straight off any balance sheet.
Current Ratio = Current Assets / Current LiabilitiesCurrent assets are things convertible to cash within a year (cash, short-term investments, accounts receivable, inventory of drugs and supplies). Current liabilities are obligations due within a year (accounts payable to suppliers, accrued wages, the portion of debt due this year).
A ratio of 1.0 means current assets exactly cover current liabilities. Higher is safer.
Back to Riverside General:
Current ratio = 220 / 130 = 1.69
A commonly cited healthy benchmark for hospitals sits around 1.5 to 2.0 (an estimate; norms vary by system size and payer mix). At 1.69, Riverside looks reasonable on this measure, even though its DCOH was borderline.
This is the important insight. Riverside's current ratio (1.69) looks fine, but its DCOH (141) looks weak. How?
Because the current ratio counts accounts receivable as a current asset. If a hospital is owed a lot by slow-paying insurers, its current ratio looks healthy while its actual cash is thin. DCOH strips receivables out and asks about real, spendable resources. That is exactly why lenders trust DCOH more for survival questions: it does not let unpaid insurer bills flatter the picture.
Rule of thumb: the current ratio measures balance, DCOH measures survival. Read them together.

2. A hospital reports strong annual profits but nearly fails to make payroll one month. What does this scenario best illustrate?
3. Why does a large amount of revenue tied up in accounts receivable make cash reserves especially critical for hospitals?

Numbers alone mislead. Three habits separate a fluent reading from a naive one.
1. Check the trend, not just the level. A hospital falling from 210 to 160 days over three years is more worrying than one steady at 140. Direction signals whether management is burning reserves to cover losses.
2. Adjust for payer mix. A hospital serving many Medicaid patients faces slower, lower reimbursement and structurally needs a bigger cushion. The same 150 days means different things in different neighborhoods.
3. Separate restricted from unrestricted funds. Some investments are legally earmarked (donor-restricted endowments, funds pledged to bondholders). Those cannot pay Tuesday's payroll, so DCOH uses only unrestricted resources. A hospital quoting a fat cash figure that includes restricted funds is overstating its true liquidity.
