What is Accrued Interest?

Accrued interest is the interest that accumulates on a debt over time. It is calculated based on the principal amount, the interest rate, and the time period for which the interest is being calculated. Understanding accrued interest is crucial for borrowers and lenders alike, as it affects the total amount owed and the cost of borrowing.

How to Calculate Accrued Interest?

The formula to calculate accrued interest is:

Accrued Interest (AI) is given by:

§§ AI = P \times r \times \frac{t}{12} §§

where:

  • § AI § — accrued interest
  • § P § — principal amount (the initial sum of money borrowed or invested)
  • § r § — annual interest rate (expressed as a decimal)
  • § t § — time period (in months)

This formula allows you to determine how much interest has accrued on a debt over a specified period.

Example:

  • Principal Amount (§ P §): $1,000
  • Interest Rate (§ r §): 5% (or 0.05 as a decimal)
  • Time Period (§ t §): 6 months

Calculating the accrued interest:

§§ AI = 1000 \times 0.05 \times \frac{6}{12} = 25 §§

Thus, the accrued interest over 6 months would be $25.

Key Terms

  • Principal Amount (P): The original sum of money borrowed or invested, before interest.
  • Interest Rate (r): The percentage at which interest is charged or earned on the principal amount, typically expressed annually.
  • Time Period (t): The duration for which the interest is calculated, often measured in months.
