How does compound interest work?
Compound interest means you earn returns on both your original investment and previously earned returns. This creates exponential growth over time, making it one of the most powerful wealth-building tools.
What's a realistic return rate for investments?
Historical stock market averages suggest 7-10% annual returns over long periods, though individual results vary. Conservative estimates often use 6-8% for planning purposes.
How much should I invest each month?
A common recommendation is 10-20% of your income, but the right amount depends on your financial goals, timeline, and current financial situation. Start with what you can afford consistently.
When should I start investing?
The best time to start investing is as early as possible to maximize the power of compound interest. Even small amounts invested early can grow significantly over decades.
What's the difference between saving and investing?
Saving typically involves low-risk, low-return accounts for short-term goals and emergencies. Investing involves higher risk but potential for greater returns over longer time periods.
How accurate are investment calculators?
Investment calculators provide estimates based on assumptions about returns and contributions. Actual results vary due to market volatility, but they're valuable for planning and understanding potential outcomes.
Should I invest if I have debt?
Generally, pay off high-interest debt first (credit cards), but consider investing while paying low-interest debt (mortgages). The decision depends on interest rates and your risk tolerance.
What's the rule of 72?
The rule of 72 estimates how long it takes investments to double. Divide 72 by your expected annual return rate. For example, at 8% returns, investments double approximately every 9 years (72÷8=9).

The compound interest calculator demonstrates how regular monthly contributions and time horizon can dramatically multiply your wealth through the power of compounding returns. By showing detailed year-by-year growth projections and investment performance analysis, our tools help you understand the true potential of consistent dollar-cost averaging and long-term investing strategies.
Whether you're saving for a house down payment, building a 6-month emergency fund, planning early retirement through index fund investing, or maximizing your 401k employer match, our investment calculators help you set realistic financial goals and track wealth-building progress. You can experiment with different monthly contribution amounts, investment time horizons, and expected annual returns (typically 7-10% for stock market investments) to find the optimal investment strategy that aligns with your risk tolerance and financial situation.
All calculations use standard financial formulas for compound annual growth rate (CAGR), present value, and future value calculations, ensuring accuracy and reliability for your investment planning and retirement projections. While these wealth-building tools provide excellent estimates for financial planning purposes, remember that actual investment returns vary due to market volatility, economic conditions, and asset allocation decisions. Past performance doesn't guarantee future results, and we recommend consulting with a financial advisor for personalized investment advice.
