What it means
Banknotes are the only form of money most people can hold directly. Everything else, from a card payment to a wire transfer, is a claim on a bank rather than money in the hand.
The historical thread explains the name. Early notes were receipts issued by banks for gold held on deposit, redeemable by whoever presented them, and the modern note kept the wording long after the metal backing disappeared.
Central banks now issue notes and carry them as a liability. Because the public holds notes without being paid interest, the central bank earns a return on the assets it holds against them, a profit known as seigniorage that is usually passed to the government.
For a business the practical question is cost. Cash takings have to be counted, reconciled, stored, insured, banked and protected against theft and error, and the total cost of handling cash commonly lands somewhere between 1% and 2% of cash turnover.
Note use is falling in most developed economies but has not disappeared. Cash still matters for small transactions, for customers without easy bank access and as a backup when card networks fail, so most retailers plan for it rather than refusing it outright.
In practice
Real-world examples.
Example
A coffee chain compares its 1.3% cash handling cost with a 1.6% card acquiring fee and decides to keep accepting notes rather than go card-only. The finance director notes that the comparison would flip if wage rates rose sharply.
Example
A central bank withdraws its largest denomination note to make bulk cash movement harder for criminals. A wholesaler that had been paying rural suppliers in cash switches to bank transfers and finds its month-end reconciliation work roughly halves.
Example
A festival operator handling $180,000 of note takings over three days pays a cash-in-transit firm $4,200 rather than send staff to a night safe. The fee works out at $4,200 / $180,000 = 2.3% of takings, which the operator accepts as the price of not carrying the money itself.
Formula
Calculation
Annual cost of handling banknotes = interest forgone on cash held + insurance and collection costs + staff time spent on cash
Cash handling cost ratio = annual cost of handling banknotes / annual cash takings
A 12-shop retailer keeps an average of $5,000 of notes in each shop, so average cash held is 12 x $5,000 = $60,000. At a 4.5% deposit rate the interest forgone is $60,000 x 0.045 = $2,700 a year.
Cash-in-transit collection and cash insurance cost $18,000 a year across the estate. Staff spend about half an hour a day per shop counting and reconciling, which over 360 trading days is 0.5 x 12 x 360 = 2,160 hours, and at a fully loaded $16 an hour that is 2,160 x $16 = $34,560.
Total cost is $2,700 + $18,000 + $34,560 = $55,260. Against annual cash takings of $4,200,000 the handling cost ratio is $55,260 / $4,200,000 = 0.0132, or 1.32% of cash turnover, which is the number to compare against card acquiring fees before anyone proposes going cashless.Case study
Seen in the real world.
Camberwood Market Group is a fictional operator of nine food halls, used here to illustrate the economics of banknotes. Roughly 40% of its $11,000,000 of annual takings arrived as notes and coins, which is $11,000,000 x 0.40 = $4,400,000 a year passing through tills by hand.
A review found the group was spending about $58,000 a year on counting, transport, insurance and till differences against those takings, or $58,000 / $4,400,000 = 1.3% of cash turnover. Management's first instinct was to go card-only, until a survey suggested about a fifth of customers regularly paid in notes.
Instead the illustrative group installed smart safes that counted notes and credited them provisionally on deposit, which allowed collections to fall from three a week to one and cut the annual cost to roughly $37,000. Camberwood kept accepting notes and stopped paying twice for the privilege.
Watch out
Common mistakes.
- Assuming cash is free because there is no card fee. Counting, transport, insurance, shrinkage and till differences all cost money and usually add up to a percentage of takings comparable with card charges.
- Confusing legal tender with an obligation to accept. Legal tender rules govern the settlement of debts, and in most countries a shop may decline cash for a new sale provided it says so clearly.
- Recording note takings only when they reach the bank. Cash is an asset from the moment it enters the till, and delaying recognition hides both shrinkage and genuine sales.
Questions
People also ask.
Are banknotes backed by gold?
Not in any major economy today; a note is a liability of the central bank whose value rests on confidence and on the central bank's control of supply.
Why are notes moving to polymer?
Polymer notes last several times longer than paper, survive accidents such as a washing machine, and carry security features that are harder to copy, which lowers the cost per year in circulation.
Should a small retailer go cashless?
Only after measuring its own cash handling cost against card fees and estimating the sales it would lose, because a small but real share of customers pay only in notes.
