What it means
Cash is the most flexible asset a business has and the least productive when it sits still. A company with $10 million in a current account earning nothing, while it pays 7% on an overdraft, has poor cash utilisation; so does one that holds cash for years without investing it or returning it.
Utilisation asks what proportion of the cash is working and what it is earning. The first measure is quantity.
Of the cash available (balances plus undrawn facilities, in the fuller sense), how much is committed to a use: the operating balance that funds daily timing gaps, the reserve held by policy, investments in progress, debt being repaid, or distributions declared? What remains idle is the utilisation gap.
A gap that is small and temporary (cash received before a scheduled payment) is normal; a gap that is large and persistent is a management failure, and the cost is the difference between what the cash earns and what it could earn. The second measure is quality.
Cash deployed into working capital that funds slow-paying customers, into equipment that runs at half capacity, or into an acquisition that returns less than the cost of capital is utilised but not well. The return on the cash used, compared with the alternatives (repaying debt, distributing to owners, a safer investment), is the test.
A business that has fully deployed its cash into low-return uses has worse cash utilisation than one holding a reserve and deploying the rest into high-return uses. The concept is prominent in investment funds, where committed capital that has not been called or invested earns nothing for investors, and utilisation (deployment rate) is a reported measure; in public bodies, where the proportion of an allocated budget actually spent is tracked as budget utilisation; and in banks, where the loan-to-deposit ratio expresses how much of the cash taken in is lent out.
In corporate finance, cash utilisation is part of capital allocation: the discipline of deciding where every dollar of cash goes and ensuring it goes there. Improving utilisation follows from measuring it.
Cash pooling and sweeping concentrate balances so that fewer are idle. A treasury policy sets the operating balance and reserve explicitly, so that the rest is visibly available.
A capital allocation process ranks uses by return and commits the surplus to the best of them or returns it. Regular reporting of idle cash, its cost and its planned use keeps the question in front of management.
And the reserve is held in instruments that earn something, so that even the cash deliberately kept back is not entirely idle.
In practice
Real-world examples.
Example
A private equity fund reports that 70% of its committed capital has been deployed after three years, within its investors' expectations.
Example
A university holds $50 million of cash across departmental accounts and, after centralising treasury, earns $1.5 million a year more on the same balances.
Example
A manufacturer discovers that $3 million of its cash is deployed in stock of a discontinued product and liquidates it to fund a new line.
Think of it
“Cash utilization is how wisely you deploy your money-are you putting it to productive use?
Formula
Calculation
Cash Utilisation Rate = Cash deployed (operations + investment + debt reduction + distributions in the period) / Cash available x 100%
Idle Cash = Total cash minus Operating balance minus Policy reserve minus Committed cash
Cost of Idle Cash = Idle cash x (Cost of capital minus Return earned on it)
Return on Deployed Cash = Incremental cash return from the use / Cash deployed
Worked example. A regional retailer's treasury review, mid-year:
- Cash across 14 accounts: $6,800,000
- Undrawn revolving facility: $3,000,000 (available liquidity $9,800,000)
- Operating balance needed (largest weekly dip over two years): $1,800,000
- Reserve policy: two months of fixed costs, $2,400,000
- Committed: dividend declared, payable next month, $700,000; store refit deposits due, $500,000
- Idle cash = $6,800,000 minus $1,800,000 minus $2,400,000 minus $1,200,000 = $1,400,000
Of the $6,800,000, $4,200,000 is in current accounts earning nothing, $2,600,000 on a 30-day deposit at 3.5%. The reserve of $2,400,000 should be earning: moving it to the deposit would earn $84,000 a year. The idle $1,400,000 earns nothing and the company pays 6.8% on a $4,000,000 term loan; repaying $1,400,000 would save $95,000 a year.
Quality review of cash deployed during the year:
- $2,000,000 into two new stores: first-year cash return $360,000 (18%); good utilisation
- $1,500,000 into inventory for a new product range: the range sold slowly and $600,000 of stock remains after eight months; cash return on the $1,500,000 about 4%; poor utilisation
- $800,000 into a system upgrade: return in efficiency savings $140,000 a year (17.5%); good
- $1,200,000 left idle on average through the year in scattered accounts: return nil; cost at the 9% cost of capital about $108,000
Actions: consolidate the 14 accounts into 3 with automatic sweeping; move the reserve to an instant-access deposit; repay $1,400,000 of the term loan; set an inventory approval process for new ranges with a cash return threshold; and report idle cash monthly with its cost. Estimated annual improvement: $84,000 + $95,000 + about $60,000 from the sweeping (interest on balances previously idle in branch accounts) = about $240,000, plus better decisions on future inventory investment.
Utilisation rate for the year: cash deployed (stores $2,000,000 + inventory $1,500,000 + system $800,000 + dividends $1,400,000 + loan repayments $600,000) = $6,300,000 against average cash available of $9,500,000 (cash plus facility): 66%. The remaining third was the operating balance, the reserve and the idle portion; after the actions, the idle portion is eliminated and the rate rises to about 80%, with the remaining 20% deliberately held.Case study
Seen in the real world.
A group of eight car dealerships, each with its own bank accounts and its own manager, held between $200,000 and $900,000 of cash per site at any time, a total averaging $4,500,000, while the group carried a $6,000,000 stocking loan at 7.5%. Each manager kept a large balance "to be safe" and to fund the used-car purchases he might want to make. The group's finance director calculated that the idle cash cost about $340,000 a year in interest that could have been avoided, and that the used-car purchasing argument was false, since the stocking loan funded purchases anyway.
He introduced a nightly sweep of each site's balance above $75,000 to the group account, which reduced the stocking loan by an average of $3,900,000; a group-level reserve of $1,000,000 held on deposit; and a monthly report to each manager of the interest cost of any balance above the target. The managers objected for a month and then stopped noticing.
Interest cost fell by about $290,000 a year, the group's reported net debt fell by $3,900,000, and the bank reduced the stocking loan margin at renewal because the group's utilisation of its own cash had improved its credit profile. The finance director's note observed that the group had been paying 7.5% to borrow its own money back from itself.
Watch out
Common mistakes.
- Measuring cash by its total and not by its use, so that idle balances persist unnoticed across accounts and subsidiaries.
- Maximising deployment for its own sake, putting cash into inventory, equipment or acquisitions that return less than repaying debt or distributing would.
- Holding the reserve in accounts that earn nothing, when instant-access deposits and money market funds would earn a return without reducing safety.
Questions
People also ask.
What is good cash utilisation?
All cash either working at a return above the cost of capital, repaying debt, or deliberately held as an operating balance or reserve in an earning instrument. Idle, unassigned cash is the measure of poor utilisation.
How does cash utilisation relate to capital allocation?
Capital allocation decides where cash goes; utilisation measures whether it went there and what it earned. Poor utilisation is usually a symptom of no allocation process.
Should a business aim for 100% utilisation?
No. The operating balance and the reserve are deliberate non-deployment, and their absence causes far more damage than their cost. The aim is zero idle cash, not zero cash.
