Understanding Stock Investment Growth
Stock investments grow through compound interest, where returns are reinvested to generate additional returns over time. Key points include:
- The future value is calculated using the formula for compound interest, adjusted for regular contributions: FV = P*(1+r)^n + PMT*((1+r)^n - 1)/r, where P is initial investment, r is the periodic rate, n is the number of periods, and PMT is the periodic contribution.
- Annual return rates are converted to monthly rates if contributions are monthly (r/12), and the number of periods adjusts accordingly.
- This calculator assumes a constant return rate and does not account for market volatility, fees, taxes, or inflation unless the return rate is adjusted for these factors.
- Regular contributions significantly boost growth due to the power of compounding over time.
Calculations are for illustrative purposes. Stock market returns are not guaranteed, and past performance is not indicative of future results. Consult a financial advisor for personalized investment advice.
FAQs
What is a realistic annual return rate for stocks?
Historically, the stock market (e.g., S&P 500) has averaged 7-10% annual returns after inflation over long periods. However, returns vary widely year to year due to market volatility. Use a conservative estimate or consult historical data for your specific investments.
Does this calculator account for taxes or fees?
No, this calculator assumes the return rate is net of fees and taxes. For a more accurate projection, reduce the return rate to account for investment fees, capital gains taxes, or other costs.
How does contribution frequency affect growth?
More frequent contributions (e.g., monthly vs. annually) allow your money to start compounding sooner, slightly increasing the future value of your investment over time.
Does the currency selection affect the calculation?
No, the currency selection is for display purposes only. The calculation remains the same regardless of the currency chosen.
