FAQs: Stock Market Calculators for Indian Traders
1. Are free stock market calculators accurate enough?
Yes, for most retail traders, free calculators from reputable brokers like Zerodha and Upstox are perfectly accurate. The paid versions offer additional features and automation that serious traders might need.
2. Which is the most important calculator for beginners?
The position size calculator is non-negotiable. It's more important than any fancy indicator or strategy for long-term survival.
3. Do I need different calculators for equity and F&O?
Yes. Equity trading requires brokerage and position sizing calculators, while F&O needs options pricing, margin, and Greeks calculators.
4. How do I account for taxes in my calculations?
Always include STT, GST on brokerage, and stamp duty in your break-even calculations. For accurate tax planning, consult a CA familiar with stock market taxation.
5. Can I rely solely on my broker's calculators?
While broker calculators are generally accurate, it's wise to cross-verify with independent calculators, especially for complex F&O strategies.
6. What's the one calculator feature most traders overlook?
Correlation analysis between different positions in your portfolio. This prevents overexposure to similar market movements.
7. Are there any SEBI-approved calculators?
SEBI doesn't "approve" specific calculators, but they mandate transparency in brokerage and charge calculations. Stick to calculators from SEBI-registered brokers for compliance assurance.
8. How often should I update my calculator inputs?
Update for every trade! Market volatility, your capital size, and risk tolerance change constantly.
