What is a Sinking Fund?

A sinking fund is a savings strategy used to set aside money over time for a specific purpose, such as purchasing an asset or paying off a debt. By regularly contributing to this fund, you can accumulate the necessary amount to meet your financial goals without straining your budget at the time of purchase.

How to Calculate the Monthly Payment for a Sinking Fund?

To determine the monthly payment required to reach your target amount, you can use the following formula:

Monthly Sinking Fund Payment (P) is calculated as:

§§ P = \frac{A \times r}{(1 + r)^n - 1} §§

where:

  • § P § — monthly sinking fund payment
  • § A § — target amount (the total amount you want to save)
  • § r § — monthly interest rate (annual interest rate divided by 12)
  • § n § — total number of payments (number of years multiplied by 12)

Example:

Suppose you want to save $10,000 over 5 years with an expected annual interest rate of 5%.

  1. Convert the annual interest rate to a monthly rate:

    • Monthly interest rate (r) = 5% / 100 / 12 = 0.004167

  2. Calculate the total number of payments:

    • Total payments (n) = 5 years × 12 months/year = 60 months

  3. Plug the values into the formula:

    • Monthly Payment (P) = (\frac{10000 \times 0.004167}{(1 + 0.004167)^{60} - 1})

  4. Calculate the result:

    • Monthly Payment (P) ≈ $188.71
