1. What is Daily Compound Interest?

Daily compound interest calculates interest on both the initial principal and the accumulated interest from previous periods, compounded daily. This results in faster growth of investments compared to simple interest or less frequent compounding.

2. How Does the Calculator Work?

The calculator uses the compound interest formula:

\[ A = P \times (1 + \frac{R}{365})^{(365 \times T)} \]

Where:

$ A $ — Maturity amount ($)
$ P $ — Principal amount ($)
$ R $ — Annual interest rate (as decimal)
$ T $ — Time period (years)

Explanation: The formula calculates how much an investment will grow when interest is compounded daily, taking into account the principal, annual rate, and time period.

3. Importance of Compound Interest

Details: Compound interest is a powerful wealth-building tool that allows investments to grow exponentially over time. Daily compounding maximizes returns by calculating and adding interest every day.

4. Using the Calculator

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

5. Frequently Asked Questions (FAQ)

Q1: How does daily compounding differ from annual compounding?
A: Daily compounding calculates interest 365 times per year, resulting in slightly higher returns than annual compounding due to more frequent interest calculations.

Q2: What is the Rule of 72?
A: The Rule of 72 estimates how long it takes for an investment to double: 72 divided by the annual interest rate gives the approximate number of years.

Q3: Are there investments that compound daily?
A: Yes, many savings accounts, money market accounts, and some investment products offer daily compounding of interest.

Q4: How does compounding frequency affect returns?
A: More frequent compounding (daily vs monthly vs annually) results in higher returns due to interest being calculated and added more often.

Q5: Is compound interest taxable?
A: Yes, interest earned through compounding is generally considered taxable income in the year it is credited to your account.
