1. What is Accrued Interest?

Accrued interest is the amount of interest that has accumulated on a principal amount but has not yet been paid or received. It's commonly used in loans, bonds, and savings accounts to track interest earned or owed between payment periods.

2. How Does the Calculator Work?

The calculator uses the simple interest formula:

Where:

• \( P \) — Principal amount (initial investment or loan amount)
• \( r \) — Annual interest rate (in decimal form)
• \( t \) — Time period in years

Explanation: The formula calculates the linear growth of interest based on the principal amount, interest rate, and time period.

3. Importance of Accrued Interest Calculation

Details: Calculating accrued interest is essential for financial planning, loan amortization, bond pricing, and understanding the true cost of borrowing or the true yield of investments.

4. Using the Calculator

Tips: Enter principal in dollars, interest rate as a decimal (e.g., 5% = 0.05), and time in years. All values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: What's the difference between simple and compound interest?
A: Simple interest is calculated only on the principal amount, while compound interest is calculated on the principal plus any accumulated interest.

Q2: How do I convert APR to a decimal?
A: Divide the percentage by 100 (e.g., 5% becomes 0.05).

Q3: Can I calculate interest for partial years?
A: Yes, enter time as a fraction of a year (e.g., 6 months = 0.5 years).

Q4: Does this work for daily or monthly interest?
A: For daily/monthly calculations, convert the time period to years (e.g., 30 days = 30/365 years).

Q5: What if I want to include compounding?
A: This calculator uses simple interest. For compound interest, a different formula is needed.
