Compound Interest Formula:

\[ FV = P \times (1 + \frac{r}{n})^{n \times t} + PMT \times \left[ \frac{(1 + \frac{r}{n})^{n \times t} - 1}{\frac{r}{n}} \right] \]

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 allows savings to grow exponentially over time, making it a powerful tool for long-term wealth building.

2. How Does the Calculator Work?

The calculator uses the compound interest formula:

\[ FV = P \times (1 + \frac{r}{n})^{n \times t} + PMT \times \left[ \frac{(1 + \frac{r}{n})^{n \times t} - 1}{\frac{r}{n}} \right] \]

Where:

$ FV $ — Future Value (currency)
$ P $ — Initial Principal (currency)
$ r $ — Annual Interest Rate (decimal)
$ n $ — Number of Compounding Periods per Year (unitless)
$ t $ — Time in Years (years)
$ PMT $ — Periodic Payment (currency per period)

Explanation: The formula calculates how much your money will grow over time with regular contributions and compound interest.

3. Importance of Regular Savings

Details: Regular contributions combined with compound interest can significantly accelerate wealth accumulation. Even small, consistent deposits can grow substantially over long periods.

4. Using the Calculator

Tips: Enter all values in the specified units. For best results, use realistic interest rates and consider increasing your periodic payments to maximize growth.

5. Frequently Asked Questions (FAQ)

Q1: How often should I compound my interest?
A: More frequent compounding (monthly vs. annually) yields higher returns due to the compounding effect.

Q2: What's a good interest rate for savings?
A: This varies by economic conditions, but typically ranges from 1-5% for savings accounts and 5-10% for long-term investments.

Q3: How much should I save regularly?
A: Aim to save at least 10-20% of your income, but any regular amount will benefit from compound growth.

Q4: When should I start saving?
A: The earlier you start, the more time compound interest has to work. Start as early as possible.

Q5: Are there risks with high-interest savings?
A: Higher returns often come with higher risks. Diversify your savings and investments to manage risk appropriately.
