What it means
The defining feature of a demand deposit is timing: the money is payable the instant you ask for it. That is different from a time deposit, where you agree to leave funds untouched for a fixed period in exchange for a higher rate.
For a business, demand deposits are the plumbing of daily operations. Payroll runs, supplier payments, card settlements and direct debits all move through them, which is why the balance sitting in one is treated as cash on the balance sheet rather than as an investment.
The trade-off is yield. Banks can lend out only a portion of instantly repayable money with confidence, so they compensate depositors thinly, and in many periods a demand deposit earns a fraction of a per cent while a money market fund earns several.
Treasurers manage that trade-off with a sweep arrangement, where any balance above an agreed operating buffer moves automatically each night into a higher-yielding account and comes back when needed. The buffer has to be genuine, because a payment that fails costs far more in fees and supplier goodwill than the interest saved.
Deposit protection is the other nuance worth knowing. Demand deposits are typically covered only up to a per-depositor limit, so a business holding several million in one account carries a concentration risk that is usually managed by spreading balances across banks.
In practice
Real-world examples.
Example
A regional coffee chain banks its card takings into a demand deposit account each evening so that Friday payroll of $186,000 clears without anyone moving money manually. The account pays almost nothing, and the finance team accepts that because the cash has to be available the moment it is needed.
Example
A software company raises $4,000,000 and parks all of it in a single demand deposit account. Its auditor flags the concentration risk, so the company moves $3,000,000 into a money market fund and keeps $1,000,000 on demand to cover the next two quarters of spending.
Example
A construction subcontractor is offered 2% off supplier invoices for paying within seven days. Because its cash sits in a demand deposit rather than a 90-day term deposit, it can take the discount immediately, which is worth far more than the interest it would have earned by locking the money away.
Formula
Calculation
Annual interest = average balance x annual rate. Opportunity cost of holding cash on demand = balance x (alternative rate - demand deposit rate).
A distributor keeps an average of $850,000 in its demand deposit account, which pays 0.10% a year. Its bank also offers a money market account paying 4.00%.
Leaving everything on demand: 850,000 x 0.0010 = $850 of interest a year.
Sweeping all but a $250,000 operating buffer: 250,000 x 0.0010 = $250, plus 600,000 x 0.0400 = $24,000, giving $24,250 in total.
Gain from the sweep: 24,250 - 850 = $23,400 a year. The same answer comes from 600,000 x (0.0400 - 0.0010) = 600,000 x 0.039 = $23,400.
Even if the alternative rate fell to 2.50%, the gain would still be 600,000 x (0.0250 - 0.0010) = 600,000 x 0.024 = $14,400 a year, which comfortably repays the few minutes a month the arrangement takes to monitor.Case study
Seen in the real world.
Larkfield Distribution is an illustrative, invented wholesaler used here to show the point. Its finance director wanted every dollar reachable within the hour, so the company held an average of $1,200,000 across two demand deposit accounts paying 0.05%. That produced 1,200,000 x 0.0005 = $600 of interest a year.
A new treasury analyst mapped six months of daily balances and found the account had never dropped below $340,000. The company set a $300,000 buffer and moved $900,000 into a money market fund paying 3.5%, earning 900,000 x 0.035 = $31,500 plus $150 on the buffer, or $31,650 in total. The change added $31,050 a year without a single late payment, and the buffer meant the operations team never noticed the difference.
Watch out
Common mistakes.
- Treating a demand deposit as a place to store surplus cash for months, when the low rate quietly costs far more than the convenience is worth.
- Assuming every dollar in the account is protected by deposit insurance, when cover usually stops at a per-depositor limit per bank.
- Confusing a demand deposit, which is an account, with a demand note or a demand draft, which are debt and payment instruments.
Questions
People also ask.
Is a demand deposit the same thing as a current account?
In most cases yes, a business current account is a demand deposit, although some instant-access savings accounts also qualify because no notice is required.
Do demand deposits count as cash in the financial statements?
Yes, they sit inside cash and cash equivalents on the balance sheet because they are available immediately and carry no meaningful risk of a change in value.
Can a bank refuse to release a demand deposit?
Only in narrow circumstances such as a court order, a fraud investigation or a formal insolvency process, because otherwise the bank is contractually obliged to pay on request.
