FAQs – Simple Stock Calculator

1. Does this calculator account for dividends? No. It tracks price performance only. Add dividend income separately if desired for complete return analysis.

2. Should I include both buy and sell commissions? Yes, typically. If planning to sell, account for sell commission in your projections. If already sold, the calculator can show historical performance.

3. What’s the break-even price? The price per share where you recover your total investment including commissions. If you break even, you have zero gain/loss.

4. How often should I update the current price? Monitor as frequently as desired. Daily tracking might cause anxiety; monthly or quarterly reviews often suffice.

5. Can I use this for mutual funds or ETFs? Absolutely. Enter the price per share and number of shares for any security.

6. What if I bought shares at different prices? Calculate separately for each purchase, or use average cost if your broker provides it.

7. Should I sell if I’m down significantly? Depends on your investment thesis. Don’t sell just because you’re down unless fundamentals have changed.

8. How does this help my investment decisions? Knowing your actual performance prevents emotional decisions. Data-driven decisions beat emotional reactions.

9. Can I compare stocks using this calculator? Yes. Compare percentage returns across different stocks to see which performed best relative to investment.

10. What if stock price drops below break-even? The calculator shows you’re underwater. Whether to hold depends on your outlook and investment timeline.

11. Should I use the break-even price as a stop-loss? Not necessarily. Stop-losses serve specific purposes. Break-even is just reference information.

12. Does this account for stock splits? No. If your stock split, adjust your share count and purchase price accordingly before calculating.

13. How do reverse splits affect my calculation? Reverse splits combine shares. Update your number of shares and purchase price to reflect the split.

14. Can I track options with this calculator? No, this is for stock shares. Options pricing involves different mechanics not covered here.

15. Should I consider taxes when deciding whether to sell? Absolutely. Short-term gains face higher taxes than long-term gains. Tax implications should influence your decision.

16. How does dollar-cost averaging affect these calculations? Calculate separately for each purchase batch, or use average cost per share if tracking an average cost position.

17. What if I sold some shares but not all? Calculate separately for the remaining position. Sold shares represent a completed transaction to analyze separately.

18. Should gains influence my holding decision? Gains or losses shouldn’t determine holding decisions alone. Base decisions on current valuation and outlook.

19. Does this calculator project future performance? No. It analyzes past and current performance only. Future performance requires separate analysis.

20. How can I improve my return percentages? Buy low and sell high (timing), choose quality companies (selection), diversify (risk management), and minimize costs (commissions).
