What is a Sinking Fund?

Sinking funds are funds that are periodically accumulated by the company as reserve. Later the reserve fund is used for a specific purpose—repayment of debts or repurchase of bonds on maturity. As a result, companies are not burdened with paying a huge sum at once.

The sinking fund also improves a company’s credibility in front of investors. It is a strategic move—companies prepare for future lump sum payments and minimize investors’ risk.

Key Takeaways

  • A sinking fund is a sum accumulated by a company over a period—every month, quarter, or year. These funds serve specific purposes, like debt repayment or bonds redemption.
  • It also provides financial security to the bond investors and thus, increases their trust in the company.
  • Companies use this fund to charge depreciation on an asset over its lifetime. They transfer an equivalent amount to the fund to replace the asset—when the asset’s useful life ends.

Example of Sinking Fund

Let us assume that P&R Ltd. issued 100 bonds, each costing $500. The bonds were issued at a 5% coupon rateCoupon RateThe coupon rate is the ROI (rate of interest) paid on the bond's face value by the bond's issuers. It determines the repayment amount made by GIS (guaranteed income security). Coupon Rate = Annualized Interest Payment / Par Value of Bond * 100%read more—payable every year for the next ten years. At the end of this tenure, the company must repurchase the bonds at par valuePar ValuePar value is the minimum value of a security set and stated in the corporate charter or its certificate by the issuer when issued for the first more. Evidently, the company declares it as a sinking fund bond and plans to deposit a sum semi-annually for ten years. Find the stockpile contribution if the annual interest rate is 6% per annum.


contribution if the annual interest
  • Money to Accumulate = $500 × 100 = $50000
  • Interest = 6% ÷ 2 = 3% or 0.03
  • Compound Frequency = 2 times (semi-annually)
  • Period = 10 years
semi-annual contributio

Therefore, PQR Ltd.’s semi-annual contribution towards the stockpile is $1860.79.
