Sinking funds are typically used by corporations to set money aside each month to pay off a debt or a bond. The corporation won’t have to pay as much out of pocket when the loan is due if it uses a sinking fund. To avoid using a credit card or withdrawing money from an emergency savings account, individuals can adopt the same technique as corporations to prepare for unforeseen costs or major expenditures.

What is a Sinking Fund? 

Sinking funds are created by bond issuers in accounting to guarantee that there will be enough money on hand to pay off the bonds when they mature. Over the course of the bond’s existence, the issuer will normally make recurring payments to the fund. 

These payments are put into low-risk investments like high-quality corporate bonds or government securities in order to make enough money to pay the bonds’ interest when they are due. As long as there is enough cash on hand to pay back the bond’s principal when it matures, the fund technique lowers the risk of default for bondholders. After understanding the sinking fund meaning let’s understand the sinking fund formula. 

The following is the sinking fund formula:

A = P * ((1 + r/n)^(t/n) – 1)/(r/n)

Where A is the total amount, P is the regular contribution, r is the interest rate, t is the number of years, and n is the number of payments made each year.

Taking into Consideration a Sinking Fund

The Companies Act of 2013 mandates that any firm that issues debentures create a sinking fund or a Debenture Redemption Reserve (DRR) to guarantee the repayment of the debentures at maturity. Before the issuing debentures are issued, the DRR should be established. It should be kept in place until the debentures are fully redeemed.

A balance sheet may occasionally include a list of long-term investments or other investments that are categorized as non-current or long-term assets, such as sinking funds. Companies that need a sizable amount of funding to buy new machinery and plants issue bonds and long-term debt.

Example of Sinking Fund in the Real World

Let’s use an actual situation to illustrate this fund concept now that you are aware of what it means. 

Consider the corporation ABC Ltd., which issued bonds with a semi-annual payment of Rs 200 crores in long-term debt. The corporation established a sinking fund, to which they were required to make a contribution of Rs 40 crores at the conclusion of each fiscal year. The corporation will have saved Rs 80 crores by the second year. Of the total debt of Rs 200 crores, Rs 120 crores were due by the third year.

Without this fund, they would have had to use their profits, cash on hand, or retained earnings to pay the whole Rs 200 crores at the conclusion of the bond’s five-year maturity period. It would have been a heavy burden for ABC Ltd. to repay the full loan, especially in light of the interest payments given to the investors over the course of the five-year period. 

Additionally, the corporation would not have been able to meet its debt obligation, which might have resulted in a default in payment, if the oil prices crashed or they were unable to get the necessary money.

Other Forms of Sinking Funds

Companies may create additional funds in addition to sinking fund bonds. As an illustration, some businesses establish equipment funds that are used to pay for equipment upgrades or replacements. The firm sets aside money each year in the equipment fund, and when the equipment has to be replaced, the corporation has the appropriate funds available.

The maintenance sinking fund is another form of sinking fund used for continuing upkeep and repairs of corporate property. Companies may make sure they have the resources necessary to maintain their assets in excellent operating order, which can assist to lower repair costs and increase the usable life of the assets, by putting money away in a maintenance fund.

Last but not least, some businesses create these funds for employee perks like pensions or other post-employment benefits. Companies can make sure they have the resources necessary to execute their responsibilities to employees when they retire or leave the firm by allocating a Fund for employee-benefit programmes. This can provide financial stability for individuals and help employers find and keep skilled staff.

Benefits and Drawbacks of Sinking Funds

They have advantages and downsides, just like any other account. The following are key advantages:

  • Preparing for unpredictable costs – A fund can be used to store money for sporadic costs like insurance premiums or auto repairs.
  • Saving over time for significant purchases – By saving a small bit at a time, you can spread out a big purchase over time using a fund.
  • Avoiding the use of a credit card or borrowing money – If you don’t have a fund, you could have to use a credit card to cover a significant cost, which would put you in debt.
  • Your funds earn the interest – You may get a return on your money by saving in a conventional or high-yield savings account.
  • Prevents impulsive purchase –   These funds may change your perspective on purchases; if you prepare and save for major costs, you’ll be less inclined to give in to persuasion and purchase things you don’t need.

Sinking funds, however, also have certain drawbacks, such as the following:

  • Slow development – saving for a significant cost might take a while, and if it takes a while to accomplish your savings target, you can become disheartened.
  • Budgeting problems – If you don’t have enough extra cash to cover your sinking fund, you can stretch your budget too thin and miss your deadline, which might put you in debt.
  • Overwhelming at times – If you have many funds, attempting to keep track of everything might rapidly become overwhelming.

Examples of Sinking Fund

The following are examples of sinking fund:

Municipal debts 

To help with the repayment of municipal bonds, certain Indian cities have set up these funds. A fund, for instance, has been established by the Pune Municipal Corporation to facilitate the payment of its bond issuances.

Infrastructure projects

These funds are used to finance a large number of infrastructure projects in India. As an illustration, the Indian National Highways Authority has set up a sinking fund to help with the repayment of loans received to create national highways.

Mutual funds

To fulfill their redemption commitments, certain mutual funds in India may utilise sinking funds. For the purpose of ensuring the sufficient liquidity to satisfy redemption requests, these funds set aside money in a sinking fund.

Insurance firms

To support their long-term responsibilities, such as the payment of annuities, Indian insurance companies may also create sinking funds. These funds are used to gradually lay aside money so that the business has the resources it needs to fulfil its future responsibilities.


Sinking funds may be a useful financial strategy for both corporations and people. It offers a means of setting money away for expected costs, easing the financial pressure of substantial payments that could otherwise be challenging to meet. One may make sure they are fully prepared to satisfy their financial responsibilities while taking advantage of chances for development and investment by setting up a sinking fund.
