1. What is the Compound Interest Formula?

The compound interest formula calculates the future value of an investment or savings account where interest is earned on both the initial principal and the accumulated interest from previous periods. This formula is particularly relevant for high-interest savings accounts like those offered by SoFi.

2. How Does the Calculator Work?

The calculator uses the compound interest formula:

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

Where:

\( A \) — Maturity amount (USD)
\( P \) — Principal amount (USD)
\( R \) — Annual interest rate (decimal)
\( n \) — Compounding frequency per year
\( T \) — Time period in years

Explanation: The formula accounts for how frequently interest is compounded, which significantly impacts the final amount earned.

3. Importance of Compound Interest Calculation

Details: Understanding compound interest is crucial for financial planning, investment decisions, and maximizing returns on savings accounts. It demonstrates how money can grow over time through the power of compounding.

4. Using the Calculator

Tips: Enter the principal amount in USD, annual interest rate as a decimal (e.g., 0.05 for 5%), compounding frequency (how many times per year interest is added), and time period in years. All values must be positive numbers.

5. Frequently Asked Questions (FAQ)
