1. What is Daily Interest?

Daily interest is the amount of interest that accrues on a loan or investment each day. For interest-only payments, this represents the daily payment amount required to cover just the interest charges without reducing the principal balance.

2. How Does the Calculator Work?

The calculator uses the daily interest formula:

\[ \text{Daily Interest} = \text{Balance} \times \left(\frac{\text{APR}}{365}\right) \]

Where:

\( \text{Balance} \) — The principal amount in dollars
\( \text{APR} \) — Annual Percentage Rate (as percentage)
\( 365 \) — Number of days in a year

Explanation: The formula converts the annual rate to a daily rate by dividing by 365 days, then multiplies by the principal balance to get the daily interest amount.

3. Importance of Daily Interest Calculation

Details: Calculating daily interest helps borrowers understand their daily cost of financing and allows for precise interest calculations between payment dates. It's particularly important for short-term loans, credit cards, and adjustable-rate products.

4. Using the Calculator

Tips: Enter the principal balance in dollars and the APR as a percentage (e.g., enter 5 for 5%). Both values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: Does this calculator account for compound interest?
A: No, this calculates simple daily interest. For compound interest, the calculation would need to account for interest being added to the principal periodically.

Q2: Why divide by 365 instead of 360?
A: Most modern financial calculations use 365 days. Some institutions use 360 days (banking method), which would result in slightly higher daily interest.

Q3: How does this relate to monthly payments?
A: Monthly interest-only payments would be approximately 30.42 times the daily interest (365 days ÷ 12 months).

Q4: Does APR include fees in this calculation?
A: No, this calculation only uses the interest rate component of APR. Fees would need to be calculated separately.

Q5: How accurate is this for leap years?
A: The difference is negligible (0.27% difference between 365 and 366 days), but for precise calculations in a leap year, you could divide by 366 instead.
