Understanding Fixed Deposit Interest

Fixed deposits are one of the most traditional and popular savings tools in Hong Kong. You place a sum of money with a bank for a fixed term, and the bank pays interest at an agreed annual rate. Compared with current deposits, fixed deposits usually offer higher interest rates, but funds generally cannot be withdrawn before maturity without losing some or all of the interest. For Hong Kong savers who are risk-averse and seek stable returns, fixed deposits are an important conservative choice.

Fixed deposit rates are affected by the market interest rate environment, deposit amount, term and bank promotions. Generally, the longer the term and the larger the amount, the higher the rate is likely to be. In recent years Hong Kong banks have frequently offered \"new money\" preferential rates to attract funds transferred from other banks. Savers can make use of these offers to boost short-term returns.

HK FinBox's fixed deposit interest calculator lets you enter the principal, annual interest rate and term to calculate the maturity interest and total principal plus interest. The calculator supports the common annual interest, monthly interest and different term settings used in Hong Kong, helping you quickly compare fixed deposit products from different banks.

Consider spreading funds across different terms to build a \"CD ladder\", balancing liquidity and return. For example, split your funds into three portions placed for one, two and three years, so a portion matures each year, giving you higher rates while retaining some flexibility. Also compare fixed deposits on the basis of annual percentage yield and check for minimum deposit requirements.

FAQs

What is the difference between a fixed deposit and a current deposit?

A fixed deposit requires funds to be locked in for a period and usually offers a higher interest rate. A current deposit can be withdrawn at any time but has a lower interest rate.

What happens if I withdraw a fixed deposit early?

Banks usually charge a penalty or deduct part of the interest. Specific terms depend on the bank and product.

How is fixed deposit interest calculated?

Interest is generally calculated based on principal, annual interest rate and term. The calculator can help estimate maturity interest and total principal plus interest.

What is a "new funds" offer?

Banks offer higher fixed deposit rates to attract new customers or newly transferred funds, usually with a minimum deposit requirement.

What is a CD ladder?

A CD ladder spreads funds across fixed deposits with different maturity dates to balance return and liquidity, so a portion matures each year.
