Compound Interest Formula:
From: | To: |
Compound interest is the interest calculated on the initial principal and also on the accumulated interest of previous periods. It's a powerful concept in investing that allows your money to grow exponentially over time.
The calculator uses the compound interest formula:
Where:
Explanation: The formula calculates how much your investment will grow when interest is compounded at regular intervals over time.
Details: Compound interest is crucial for long-term stock investments as it allows your returns to generate additional returns, creating exponential growth over extended periods.
Tips: Enter principal amount in currency, annual interest rate as decimal (e.g., 0.08 for 8%), compounding frequency per year, and time in years. All values must be positive.
Q1: How does compounding frequency affect returns?
A: More frequent compounding (daily vs. annually) results in higher returns due to interest being calculated on accumulated interest more often.
Q2: What's a typical compounding frequency for stocks?
A: Stock investments typically compound continuously, but this calculator allows you to specify any compounding frequency.
Q3: How accurate is this calculation for real stock investments?
A: This provides a theoretical calculation. Actual stock returns vary and are not guaranteed like fixed-interest investments.
Q4: Can I use this for dividend reinvestment calculations?
A: Yes, this calculator can model dividend reinvestment scenarios by using dividend yield as the interest rate.
Q5: What's the difference between simple and compound interest?
A: Simple interest is calculated only on the principal amount, while compound interest calculates interest on both principal and accumulated interest.
