About Stock Investments

Stock investments involve purchasing shares of ownership in a company. Returns come from two primary sources: capital appreciation (increase in share price) and dividends (periodic payouts to shareholders).

Types of Returns
  • Capital Gains: Profit from selling shares at a higher price than purchase price.
  • Dividends: Regular payments distributed from company profits to shareholders.
  • Total Return: Combined return from both capital gains and dividends.
Investment Performance Metrics
  • ROI (Return on Investment): Percentage gain or loss on your initial investment.
  • Annualized Return: Yearly compound growth rate of your investment.
  • Cost Basis: Original value of investment plus any brokerage fees.
  • Tax Implications: Capital gains taxes on profits may vary based on holding period.
Tips for Stock Investing
  • Diversify your portfolio to spread risk across different stocks and sectors.
  • Consider both growth potential and dividend yield when selecting stocks.
  • Be aware of short-term vs. long-term capital gains tax implications.
  • Factor in brokerage fees and commissions when calculating true returns.
  • Remember that past performance doesn't guarantee future results.

Overview of the Stock Investment Calculator

It allows you to calculate key metrics such as total profit or loss, annualized returns, and potential tax on capital gains.

Frequently Asked Questions

What is ROI and why does it matter?

ROI (Return on Investment) tells you how much profit or loss you’ve made compared to the amount you invested. It’s useful for comparing different investments and tracking performance.

What is annualized return?

Annualized return expresses your total gain or loss as a yearly rate. This makes it easier to compare investments with different time spans.

Can this calculator account for inflation?

Yes. There’s an option to adjust your results for inflation, giving a more realistic view of your investment’s buying power over time.

Does this include dividends?

Absolutely. Just enter the total dividends received to include them in your profit and ROI calculations.

Is tax included in the results?

Yes. If you enter your capital gains tax rate, the calculator estimates how much tax you might owe and shows your after-tax profit.
