Frequently Asked Questions
What is compound interest?
Compound interest is the interest on a loan or deposit calculated based on both the initial principal and the accumulated interest from previous periods.
How often should I compound?
The more frequent the compounding (e.g., daily instead of annually), the faster your investment grows. Common frequencies are monthly (12) or quarterly (4).
Does this account for monthly deposits?
This is a basic compound interest calculator for a lump sum investment. It does not currently account for additional monthly contributions.
