1. What is Accrued Interest?

Accrued interest is the amount of interest that has accumulated on a debt or investment but has not yet been paid or received. It's calculated based on the principal amount, interest rate, and time period.

2. How Does the Calculator Work?

The calculator uses the accrued interest formula:

\[ \text{Accrued} = \sum (P \times \text{Daily Rate} \times \text{Days Segment}) \]

Where:

\( P \) — Principal amount in dollars
\( \text{Daily Rate} \) — Annual rate divided by 365 days (decimal)
\( \text{Days Segment} \) — Number of days between start and end date

Explanation: The formula calculates interest for each day by multiplying the principal by the daily rate, then sums these amounts over the specified period.

3. Importance of Accrued Interest Calculation

Details: Accurate accrued interest calculation is crucial for financial reporting, bond pricing, loan accounting, and investment analysis. It ensures proper recognition of interest income or expense.

4. Using the Calculator

Tips: Enter the principal amount, start and end dates, and annual interest rate. The calculator will compute the accrued interest for the period.

5. Frequently Asked Questions (FAQ)

Q1: What's the difference between simple interest and accrued interest?
A: Simple interest is calculated only on the principal, while accrued interest accounts for interest that accumulates over time but hasn't been paid.

Q2: How does compounding affect accrued interest?
A: This calculator uses simple interest. For compound interest, the calculation would be more complex as interest earns additional interest.

Q3: What's the difference between 365-day and 360-day year calculations?
A: Some financial instruments use 360 days for simplicity. This calculator uses 365 days for daily rate calculation.

Q4: Can I calculate accrued interest for multiple rate changes?
A: This calculator assumes a constant rate. For multiple rates, you would need to calculate each period separately and sum the results.

Q5: How is accrued interest treated for tax purposes?
A: Accrued interest may be taxable when earned, even if not yet received. Consult a tax professional for specific advice.
