Sinking Fund

If you have a major expense coming up, like a car repair or home upgrade, and want to avoid last-minute financial stress, a sinking fund can help. By setting aside money regularly, you can cover big costs without touching emergency savings or going into debt. Whether you’re experienced or new to managing money, knowing how sinking funds work adds more control to your finances.

Key Takeaways

  • Defined Purpose: A sinking fund is a savings account created for a specific future expense, such as a major purchase or debt repayment. It helps avoid financial strain by planning ahead rather than relying on credit.
  • Different From Other Savings: Unlike emergency funds or general savings, a sinking fund is reserved for known, expected costs. It follows a fixed plan with clear goals and a timeline.
  • Simple Setup Process: Creating a sinking fund involves identifying the goal, selecting where to save, calculating the required contributions, and adding it to your monthly budget. This structure keeps your saving efforts consistent and on track.

What Is A Sinking Fund?

A sinking fund refers to a dedicated account established with the specific purpose of repaying an existing debt. The account holder contributes a fixed amount of money on a regular basis, ensuring the funds are reserved exclusively for this single objective. In a corporate context, sinking funds are typically used in relation to bonds, where the company sets aside money to repurchase issued bonds or portions of them before they reach their official maturity date. This approach can also serve to reassure potential investors, as it demonstrates the issuer’s commitment to honouring their repayment obligations.

The primary goal of a sinking fund is to make the process of settling a debt more manageable while reducing the likelihood of default. By building up a reserve over time, there is greater assurance that sufficient funds will be available when repayment is due. Although many bonds require several years to mature, gradually reducing the outstanding capital in advance can help lower the overall credit risk and ease the financial burden.

What A Sinking Fund Is Not

Although they may seem similar at first, a sinking fund is not the same as an emergency fund, which tends to have a broader, non-specific purpose. An emergency fund is designed to provide a financial buffer for unexpected events. You might not know exactly what you are saving for, but you want to ensure you are financially prepared if a crisis occurs.

An emergency fund is useful for covering unforeseen expenses or managing through difficult times, such as a sudden job loss or urgent home repairs that require immediate attention.

There is some overlap between sinking funds and emergency funds in that both aim to help you avoid going into debt. Whether the expense is expected or comes as a surprise, setting aside money in advance gives you a way to cover costs without borrowing.

However, a sinking fund is different from general savings. While a savings account might hold funds for a variety of needs, a sinking fund is dedicated to a specific financial goal. It is a targeted approach to saving, usually with a fixed timeline or purpose in mind.

Uses Of A Sinking Fund

Consumers

For Organisations

  • Debt Repayment: Companies, particularly those that issue bonds, often establish sinking funds to ensure they can meet their debt obligations when they become due. This reduces the likelihood of default and provides a measure of reassurance to investors. This method is especially useful when dealing with long-term debt.
  • Asset Replacement: Businesses make regular contributions to sinking funds to prepare for the eventual replacement of assets such as vehicles, equipment, or factory machinery. This allows them to avoid unexpected financial strain by planning for large capital expenses over time.
Care Dependency Grant

For Individuals

  • Loan Repayment: Individuals can make use of a sinking fund to gradually save money towards repaying loans, including car finance and home loans. This method supports faster debt clearance and more structured personal financial management.
  • Major Purchases: A sinking fund can be used to set aside money for significant future expenses, such as buying a new vehicle, carrying out home upgrades, or making a deposit on a property.
  • Planned Expenses: Sinking funds assist with preparing for expected but infrequent costs, including yearly insurance premiums, rates and taxes, or expenses related to the festive season. This prevents the need to rely on credit when these payments arise.
  • Educational Expenses: Many South Africans use sinking funds to build up savings for future costs related to education, such as school fees, university tuition, or study materials. This ensures money is available when needed, reducing pressure on household budgets.

How To Create A Sinking Fund

Now that the concept of a sinking fund is clear, here is a practical guide on how to set one up in four straightforward steps.

Identify The Purpose Of Your Sinking Fund


Start by determining what specific expense you are preparing for. It could be something like a holiday, the deposit for a home, festive season gifts, or an upcoming wedding. Whatever the goal may be, it is best to plan for it in advance so that the cost does not catch you off guard and place unnecessary strain on your finances.

Choose Where You Will Keep Your Savings


Select a safe and convenient place to store your sinking fund. Many prefer to open a separate savings account dedicated to this purpose. Make sure the account does not require a minimum balance or charge monthly fees, as these can slowly reduce your savings over time.

If you are using a budgeting tool that allows fund allocation within your budget, such as EveryDollar, you might not need a separate bank account. The tool will track your sinking fund as part of your overall budgeting system.

Work Out How Much You Need To Save


To calculate your savings target, divide the total amount required by the number of months or weeks available before you need to use the funds.

For instance, if you plan to spend R1 000 on Christmas and it is currently September, you have approximately three months to save. This means you should include around R330 in your monthly budget to reach your target by December.

Include The Sinking Fund In Your Monthly Budget


A sinking fund is only effective if it is part of your regular budget. Whether you prefer to budget using a spreadsheet, an app, or by writing it down, ensure that your sinking fund is listed as a specific item. This keeps you accountable and allows you to monitor your progress with clarity.

Should You Sink Your Funds into a Sinking Fund?

Sinking funds can be a sensible option for long-term financial goals, offering stability, tax efficiency, and a structured approach to saving over a minimum term of five years. Unlike endowment policies, they are not tied to a life assured, which allows for greater flexibility in estate planning. While they are less suitable for short-term needs due to limited access to funds during the initial term, and investors should be aware of platform fees and the lack of creditor protection, they do offer predictable returns and reduced tax administration. For individuals in higher tax brackets or those planning for expenses such as education or retirement, sinking funds are certainly worth considering.

Advantages Of Sinking Funds

The points below outline the key benefits of having a sinking fund in place:

Attracts Investors

Investors generally view companies with substantial debt as carrying a higher level of risk. However, when a company has an established sinking fund, it provides a sense of financial security. This is because investors are more confident that, even in the event of a default or financial collapse, there are funds available to repay what is owed to them.

Potential For Lower Interest Rates

Companies with weak credit profiles often struggle to attract funding without offering high interest rates. The presence of a sinking fund reduces the risk to investors, which may enable the company to raise capital at more favourable interest rates compared to companies without such a financial cushion.

Improved Financial Stability

A company’s financial health can fluctuate due to changing market conditions or unexpected setbacks. By having a sinking fund, a company can meet its debt obligations and repurchase bonds without jeopardising its overall financial position. This helps maintain a strong credit record and assures investors of the company’s ability to manage its commitments responsibly.

Where To Keep Your Sinking Fund

Where To Keep Your Sinking Fund

When you are ready to start putting money aside specifically for your sinking fund, it is usually a good idea to open a separate savings account that is not linked to your everyday spending or general savings. Keeping these funds isolated can help ensure they are used only for their intended purpose. Fortunately, there are several practical options available for South Africans looking to store their sinking fund:

OptionDescription
Cheque AccountIf the goal you are saving for is just around the corner, you might find it most convenient to place your sinking fund into a standard cheque account. This allows immediate and unrestricted access to your money when the time comes to make the purchase. However, cheque accounts generally offer little to no interest, so they are not ideal for long-term saving.
High-Interest Online Savings AccountIf you are looking to earn more interest on your savings, consider opening a high-interest online savings account. These are often provided by digital-only banks, which tend to have lower operating costs than traditional banks. As a result, they can often offer better interest rates and lower account fees. The higher interest helps your money grow passively, making it a suitable option for medium- to long-term savings.
Money Market AccountAnother possibility is a money market account. These accounts allow you to earn interest while still maintaining access to your funds. Compared to traditional savings accounts, money market accounts often offer more flexibility, such as the option to write cheques or make payments directly from the account, depending on the bank’s terms.

Conclusion

A sinking fund is a practical and disciplined way to manage future expenses without putting pressure on your emergency savings or relying on debt. Whether you’re an individual planning for annual costs or a business preparing to repay bonds or replace assets, setting aside money consistently helps you stay financially prepared. In the South African context, where financial demands are often unpredictable, using a sinking fund allows for more controlled and intentional budgeting. By following a clear savings plan and keeping the fund separate from your everyday spending, you can meet financial goals with less stress and greater confidence.

Frequently Asked Questions

What is the main difference between a sinking fund and an emergency fund?

A sinking fund is meant for a planned and specific expense that you expect to occur in the future, such as school fees or a home upgrade. An emergency fund, on the other hand, is set aside to help you cover unforeseen expenses like medical emergencies or unexpected car repairs.

Can I have more than one sinking fund at the same time?

Yes, it is common for people to maintain several sinking funds at once, each dedicated to a different financial goal. For example, you might have one for annual insurance premiums, another for travel, and a third for upcoming household repairs.

How much should I contribute to a sinking fund each month?

To work this out, divide the total amount you need by the number of months (or weeks) left before the expense is due. This gives you a clear savings target to include in your budget so that you reach your goal on time without financial stress.

Where is the best place to keep a sinking fund in South Africa?

The most suitable place is usually a separate account such as a high-interest online savings account, a traditional savings account with low fees, or a money market account. These options allow you to earn some interest while keeping the money separate and easily accessible when needed.

Can a sinking fund help with debt repayment?
