1. What is Daily Compound Interest?

Daily compound interest means that interest is calculated on your principal plus accumulated interest every day, leading to faster growth of your investment compared to simple interest or less frequent compounding.

2. How Does the Calculator Work?

The calculator uses the daily compounding formula:

Where:

• \( Principal \) — Initial investment amount
• \( Rate \) — Annual interest rate (as decimal)
• \( Years \) — Time period in years
• 365 — Days in year for daily compounding

Explanation: The formula accounts for interest being calculated and added to the principal balance each day, leading to exponential growth.

3. Importance of Compound Interest

Details: Understanding compound interest is crucial for financial planning, as it demonstrates how investments grow over time and the power of starting early.

4. Using the Calculator

Tips: Enter principal amount in dollars, annual interest rate as percentage (e.g., 5 for 5%), and time period in years. All values must be positive numbers.

5. Frequently Asked Questions (FAQ)

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

Q2: What's the difference between APR and APY?
A: APR is the annual rate without compounding, while APY includes compounding effects. This calculator shows APY equivalent results.

Q3: How accurate is this calculator?
A: It provides precise mathematical results assuming constant rate and no additional deposits/withdrawals.

Q4: Can I use this for loans?
A: Yes, it works similarly for debt, showing how much you'll owe with daily compounding interest.

Q5: Why 365 days? What about leap years?
A: Financial calculations typically use 365 days. The difference for leap years is negligible for most purposes.
