A: Simple interest is calculated only on the principal amount, while compound interest is calculated on both the principal and accumulated interest.
Q2: How does compounding frequency affect returns?
A: More frequent compounding (monthly vs annually) results in higher returns due to interest being calculated on interest more frequently.
Q3: What is a typical compounding frequency?
A: Common frequencies include annually (1), semi-annually (2), quarterly (4), and monthly (12).
Q4: Can this calculator be used for loans?
A: Yes, the same formula applies to compound interest on loans, though the context differs from investment growth.
Q5: How accurate is this calculator for real-world scenarios?
A: This provides a mathematical estimate. Actual returns may vary based on specific financial product terms and market conditions.
