What Are Sinking Funds?

A sinking fund is a financial strategy used by individuals, businesses, and governments to set aside money for future expenses. The aim of a sinking fund is to avoid having to borrow money in future or depleting your savings when the need arises.

Let’s understand what a sinking fund is, the different types of sinking funds, and how to start one.

What Is a Sinking Fund?

A sinking fund is money set aside regularly over time to meet a specific future expense, repay a debt, or replace an asset. It helps individuals and businesses prepare for large expenses in advance.

How To Calculate Sinking Fund Amount?

The following is the formula used to calculate the sinking fund amount.

S = (P × i) / ((1 + i)^n − 1)

Where:

S = amount saved in each period

P = target amount needed in the future

i = interest rate per period

n = total number of saving periods

For example, if you need to save ₹10,000 over a period of 10 years and your savings earn a fixed annual return of 5%, you would need to save around ₹795 at the end of each year, assuming contributions are made at the end of each year.

S = (10,000 * 0.05) / (1 - (1 + 0.05)^-10) = ₹795.05 every year at 5% interest to accumulate ₹10,000 in 10 years, assuming deposits are made at the end of each year.

This means that you would need to contribute ₹795.05 at 5% to the sinking fund each year for 10 years to accumulate enough money to repay the debt.

Types of Sinking Funds

The following are the types of sinking funds.

Debt Repayment Sinking Fund

A debt repayment sinking fund helps you save money for a planned debt payment. It can be used for certain loan repayments or bond obligations. Paying off high-interest debt, such as credit card debt, as early as possible may be better than saving money separately while interest continues to build up.

Asset Replacement Sinking Fund

An asset replacement fund is used to replace an asset such as a car, machinery, or equipment. By making regular contributions to a sinking fund, you can accumulate enough money to buy a replacement asset when the time comes. This can help you avoid taking out a loan to buy the asset or dipping into your savings.

Emergency Fund

An emergency fund is money kept aside for unexpected expenses, such as medical bills, home repairs, or job loss. It is different from a sinking fund because a sinking fund is generally used for expenses that you can plan for in advance. SEBI also recommends maintaining an emergency fund to deal with unexpected financial needs.

Specific Purpose or Major Purchase Fund

This type of fund is created with the aim of reaching a distinct milestone, such as a home down payment, a wedding, a vacation, or a child's higher education tuition.

How to Start a Sinking Fund?

Here’s how you can start a sinking fund.

Set Your Goal

The first step is to determine your financial goal. This could be repaying a debt, replacing an asset, or saving for a future expense. Determine how much money you need to achieve your goal and when you need it.

Determine Your Contributions

The next step is to determine how much money you need to contribute to the sinking fund regularly. You can use the sinking fund formula to calculate your contributions. This will depend on the interest rate, the number of payment periods, and the target amount you need to accumulate.

Open a Separate Account

It is helpful to keep your sinking fund separate from your regular spending money so that you do not use it for other purposes. You can use a separate savings account or another suitable option based on when you will need the money and how much risk you can accept.

Make Regular Contributions

Once you have determined your contributions and opened a separate account, it is important to make regular contributions to the sinking fund. This can be done on a weekly, monthly, or quarterly basis, depending on your budget and financial goals.

Track Your Progress

It is important to track your progress and make adjustments as necessary. Review your sinking fund regularly to ensure that you are on track to achieve your financial goals.
