1. What is the Daily Compounding Interest Formula?

The daily compounding interest formula calculates the future value of an investment when interest is compounded daily. It shows how savings grow faster with more frequent compounding compared to annual or monthly compounding.

2. How Does the Calculator Work?

The calculator uses the daily compounding formula:

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

Where:

$ A $ — Maturity amount ($)
$ P $ — Principal amount ($)
$ R $ — Annual interest rate (decimal)
$ T $ — Time period (years)
365 — Number of compounding periods per year

Explanation: The formula calculates how your principal grows when interest is calculated and added to your balance every day.

3. Importance of Daily Compounding

Details: Daily compounding allows your investment to grow faster than less frequent compounding because interest is calculated on both the principal and previously earned 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)
