1. What is Daily Compounding?

Daily compounding means that interest is calculated and added to the principal balance every day. This results in earning "interest on interest" more frequently than monthly or annual compounding, leading to higher returns over time.

2. How Does the Calculator Work?

The calculator uses the daily compounding formula:

\[ FV = Principal \times (1 + \frac{Rate}{365})^{(365 \times Time)} \]

Where:

\( Principal \) — Initial investment amount
\( Rate \) — Annual interest rate (as decimal)
\( Time \) — Investment period in years
\( 365 \) — Number of compounding periods per year

Explanation: The formula accounts for the exponential growth of money when interest is compounded daily, with interest being calculated on both the principal and accumulated interest.

3. Importance of Daily Compounding

Details: Daily compounding can significantly increase investment returns compared to less frequent compounding. Even small differences in compounding frequency can lead to substantial differences in final amounts over long periods.

4. Using the Calculator

Tips: Enter the principal amount in dollars, annual interest rate as a percentage, and time in years. All values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: How does daily compounding compare to monthly compounding?
A: Daily compounding typically yields slightly higher returns than monthly compounding because interest is calculated and added more frequently.

Q2: Is this formula used for all money market accounts?
A: Most money market accounts use daily compounding, but always check with your financial institution as terms may vary.

Q3: What's the difference between APR and APY?
A: APR doesn't account for compounding, while APY does. This calculator shows the APY effect of daily compounding.

Q4: How accurate is this calculator for real-world investments?
A: It provides theoretical results. Actual returns may vary due to changing rates, fees, or other account terms.

Q5: Can I use this for other compounding periods?
A: This specific calculator is for daily compounding. Different formulas are needed for other compounding frequencies.
