Fixed-Term Deposits Explained: How CDs and Term Deposits Work
Lock in a rate, plan your term and understand what early withdrawal really costs.
Key takeaways
- A fixed-term deposit pays a guaranteed rate for a set period, in exchange for locking your money away.
- Withdrawing early usually costs a penalty, often several months of interest, or is not possible at all.
- Longer terms do not always pay more; compare rates across terms before committing.
- A deposit ladder spreads money across several maturities to balance rate and flexibility.
Fixed-term deposits go by many names. In the US they are called certificates of deposit (CDs), in the UK fixed-rate bonds, and in much of Europe and Australia term deposits. The idea is the same everywhere: you deposit a sum for an agreed period, the bank guarantees the interest rate, and you get your money back with interest when the term ends.
How a fixed-term deposit works
You choose an amount and a term, for example 6 months, 1 year or 5 years. The rate is fixed on the day you open the deposit and does not change, no matter what happens to market rates afterward. At maturity you receive your deposit plus interest, and many banks then offer to roll it over into a new term at whatever rate applies at that time.
Interest is either paid out regularly (monthly or yearly) or added to the deposit and paid at the end. If interest is added and compounds, the effective yield is slightly higher. Example: $10,000 at a fixed 4.00% with annual compounding grows to about $12,167 after five years. If the interest were paid out each year instead, you would receive $400 per year, $2,000 in total.
Fixed-term deposit vs. savings account
| Fixed-term deposit | Savings account | |
|---|---|---|
| Interest rate | Fixed for the whole term | Variable, can change anytime |
| Access to money | Locked until maturity (or penalty) | Usually available any day |
| Best for | Money you will not need for a known period | Emergency fund, short-term goals |
| Main risk | Rates rise after you lock in; inflation | Rates fall; inflation |
The main advantage of a fixed term is certainty: if rates fall, your rate stays put. The trade-off is flexibility and the risk of missing out if rates rise. For money you may need at short notice, a savings account is usually the better home.
How deposit rates are set
Banks price fixed-term deposits based on what they expect interest rates to do. When markets expect central banks to cut rates, long-term deposits may pay less than short-term ones, because banks do not want to lock in high costs for years. When rate rises are expected, longer terms tend to pay more. That is why it pays to compare the rates for several terms rather than assuming that longer is always better.
Competition matters too. Smaller banks and online banks that need deposits to fund their lending often pay noticeably more than large high-street banks.
Early withdrawal: what it really costs
Some fixed-term deposits cannot be broken at all before maturity. Others allow early withdrawal but charge a penalty. A common structure for US CDs is a penalty equal to a number of months of interest, for example 3 months for a 1-year CD and 6 to 12 months for longer terms.
Example
You put $10,000 into a 1-year CD at 4.50%. Your full-term interest would be $450. If the penalty is three months of interest, breaking the CD early costs about $112.50, and if you withdraw very early the penalty can exceed the interest earned so far, reducing your principal.
Always read the early withdrawal terms before you open the deposit, and only lock away money you are confident you will not need.
Choosing the right term length
- Match the term to a goal. If you need money for a down payment in 18 months, a term that matures before then makes sense.
- Compare across terms. A 12-month deposit sometimes pays as much as a 3-year one.
- Think about rate expectations, but do not try to time the market perfectly; nobody can.
- Mind the rollover. Note the maturity date. Automatic renewals may happen at a lower rate.
The deposit ladder strategy
A ladder splits your money across several deposits with staggered maturities. Instead of putting $20,000 into a single 4-year deposit, you might put $5,000 each into 1-, 2-, 3- and 4-year deposits. Every year one deposit matures. You can then use the money or reinvest it in a new 4-year deposit.
A ladder gives you regular access to part of your money, reduces the risk of locking everything in at the wrong moment and, once established, lets most of your money earn longer-term rates.
Risks to keep in mind
- Inflation risk: a fixed rate can lose value in real terms if inflation rises above it.
- Opportunity cost: if rates climb after you lock in, you earn less than new customers.
- Provider risk: check that the bank is covered by deposit insurance, such as the FDIC in the US (up to $250,000 per depositor, per bank, per ownership category) or the national scheme in your country. Deposits at banks abroad are covered by that country's scheme.
- Brokered CDs bought through a brokerage account behave differently: they can often be sold before maturity, but the price can be lower than what you paid if rates have risen.
The bottom line
A fixed-term deposit is a simple way to earn a guaranteed rate on money you will not need for a while. Compare rates across terms and providers, read the early withdrawal rules and consider a ladder if you want both a good rate and regular access. Explore more in our fixed-term deposit guides.
