What it means
The mechanics are simple: you agree an amount, a term and a rate, and the bank returns your money plus interest on the maturity date. Terms commonly run from 30 days to five years, and the rate is locked for the whole period whatever happens to market rates.
For a business, term deposits sit between a current account earning almost nothing and an investment that could fall in value. The capital is not exposed to market movements, so the only real questions are the rate, the term and how quickly the money could be recovered if plans change.
Choosing the term is where the skill lies. Finance teams build a cash forecast, identify the surplus that is genuinely not needed for the next few months, and ladder deposits so a tranche matures every month or quarter rather than locking everything away at once.
Breaking a term deposit early is possible but costly. Banks typically apply a reduced interest rate for the period the money was actually held, and sometimes an administrative fee, so the effective return can fall to a fraction of the headline rate.
Interest treatment varies and is worth confirming before you sign. Some deposits pay interest at maturity, some pay monthly or quarterly into a current account, and compounding only helps if the interest stays inside the deposit.
The main nuance is inflation and opportunity cost. A fixed 4% return feels comfortable when rates are falling and painful when rates rise sharply mid-term, which is exactly why laddering rather than a single long deposit is standard treasury practice.
In practice
Real-world examples.
Example
A retailer holding $600,000 of reserve cash splits it into four $150,000 deposits maturing at 3, 6, 9 and 12 months. The ladder gives access to cash every quarter without giving up the higher rate paid on the longer tranches.
Example
A charity receives a $2 million legacy to be spent over three years. The trustees place $1.2 million on a two-year term deposit at 4.5%, earning about $54,000 a year while the grant programme is designed.
Example
A manufacturer breaks a 12-month deposit after 5 months to cover an unexpected equipment failure. The penalty rate cuts the return from 5% to 1.5%, costing roughly $8,750 of interest on a $600,000 deposit.
Formula
Calculation
Interest on a simple term deposit = principal x annual rate x (days in term / 365). Maturity value = principal + interest.
A distributor places $250,000 on a 180-day term deposit at 4.8% a year. A full year of interest would be $250,000 x 0.048 = $12,000, so the interest for 180 days is $12,000 x (180 / 365) = $5,917.81.
The maturity value is $250,000 + $5,917.81 = $255,917.81.
If the company had to break the deposit on day 90 and the bank applied a penalty rate of 2.4%, the interest would be $250,000 x 0.024 x (90 / 365) = $1,479.45. That compares with the $2,958.90 it would have accrued over the same 90 days at the contracted 4.8%, so the break costs $1,479.45 in forgone interest on top of losing the remaining term.Case study
Seen in the real world.
This illustrative and fictional example follows Cobalt Press, an invented specialist book printer holding $1,500,000 of cash after selling a warehouse. The finance director placed the whole sum into a single three-year term deposit at 4.2%, expecting about $63,000 of interest a year.
Eleven months later a press failed and Cobalt needed $500,000 quickly. Because the money sat in one contract it could not be broken in part, so the entire deposit was closed and the penalty rate of 1.0% reduced eleven months of interest from about $57,750 to $13,750, a loss of $44,000.
The board then adopted a laddering policy: no more than a third of surplus cash in any one deposit, and at least one tranche maturing each quarter. The illustrative lesson is that the best protection against a broken deposit is not a better rate but a better spread of maturity dates.
Watch out
Common mistakes.
- Locking away cash that the forecast already shows will be needed before the maturity date, which almost guarantees a break penalty.
- Comparing a term deposit rate with a savings rate without noting that one is fixed for the term and the other can move at any time.
- Assuming interest compounds automatically, when many deposits pay interest away to a current account and therefore earn simple interest only.
Questions
People also ask.
Can a term deposit lose money?
Not in nominal terms with a covered bank, though its real value falls if inflation runs above the fixed rate for the term.
What happens at maturity if I do nothing?
Most banks roll the deposit into a new term at the prevailing standard rate, which is often worse than a rate you could negotiate, so the maturity date belongs in the diary.
Is a term deposit the same as a certificate of deposit?
They are close relatives; a certificate of deposit is a tradable instrument in some markets, while a term deposit is normally a private contract with the bank that cannot be sold on.
