Compound interest is interest earned on both the original principal and on previously accumulated interest, so the balance grows faster over time.
Yes. The more often interest compounds, the higher the final amount for the same nominal rate — monthly compounding beats yearly compounding.
Each contribution starts earning its own compound interest from the moment it is added, so regular contributions can outgrow a larger one-time deposit over long periods.
