How Do Investment Calculators Work?

Investment calculators use compound interest formulas to project how your money can grow over time. You can solve for the ending amount, required contribution, return rate, starting amount, or investment length—each mode helps answer a different financial question.

Modes Explained

End Amount: See how much your investments will grow based on your inputs.
Additional Contribution: Find out how much you need to contribute to reach a target.
Return Rate: Calculate the annual return rate required to hit your goal.
Starting Amount: Determine the lump sum needed to reach your target.
Investment Length: See how long it will take to reach your goal.

Common Questions

What is compound interest?: Compound interest is interest calculated on both the initial principal and the accumulated interest from previous periods.
How often should I contribute?: Monthly contributions are common, but the calculator supports both monthly and yearly options for flexibility.
What is a realistic return rate?: Historical stock market returns average 6-8% after inflation, but actual returns can vary. Adjust the rate to match your risk tolerance and investment type.
How accurate are the results?: Calculations are based on mathematical formulas and your inputs. Actual investment performance may differ due to market fluctuations, fees, and taxes.
