Compound Interest Calculator
Project the future value of savings with compound interest and optional monthly contributions.
Limitations: Assumes a constant interest rate. Real-world returns (stocks, bonds, etc.) vary year to year. Does not account for fees or taxes on gains.
What to do next: For market investments, use the historical long-term real return (~7% stocks, ~2–3% bonds) as a rough estimate — actual returns in any single year range widely.
