1. What is Compound Interest?

Compound interest is the interest calculated on the initial principal and also on the accumulated interest of previous periods. It differs from simple interest, where interest is not added to the principal for subsequent calculations.

2. How Does the Calculator Work?

The calculator uses two compound interest formulas:

\[ Daily: A = P \times (1 + \frac{R}{365})^{(365 \times T)} \] \[ Monthly: A = P \times (1 + \frac{R}{12})^{(12 \times T)} \]

Where:

\( A \) — Maturity amount
\( P \) — Principal amount (initial investment)
\( R \) — Annual interest rate (in decimal form)
\( T \) — Time in years

Explanation: The more frequently interest is compounded, the greater the return, as interest is earned on interest more frequently.

3. Daily vs Monthly Compounding

Details: Daily compounding calculates and adds interest every day, while monthly compounding does so once per month. Daily compounding typically yields slightly higher returns due to more frequent compounding periods.

4. Using the Calculator

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

5. Frequently Asked Questions (FAQ)

Q1: Which compounding frequency is better?
A: Daily compounding typically yields slightly higher returns than monthly compounding due to more frequent compounding periods.

Q2: How significant is the difference between daily and monthly compounding?
A: The difference is usually small but becomes more noticeable with larger principal amounts, higher interest rates, and longer time periods.

Q3: Are there other compounding frequencies?
A: Yes, interest can be compounded annually, semi-annually, quarterly, monthly, weekly, daily, or even continuously.

Q4: Does this calculator work for loans as well as investments?
A: Yes, the same formulas apply to both investments and loans, though for loans, more frequent compounding means paying more interest.

Q5: What is continuous compounding?
A: Continuous compounding is the theoretical limit of compounding frequency, calculated using the formula \( A = P \times e^{(R \times T)} \), where e is Euler's number.
