Frequently Asked Questions
How do I calculate my average share price?
Divide total money invested by total shares: 10 shares at $50 plus 20 at $35 is $1,200 for 30 shares — a $40 average, not the $42.50 midpoint of the prices.
Is averaging down a good idea?
It lowers your breakeven but concentrates more money in the same stock. It works when your original thesis still holds; it compounds losses when the business has genuinely deteriorated.
Can I use the result as an exact answer?
Treat it as an estimate or check unless the page and the rules that apply to you confirm otherwise. Rounding, fees and personal details can change the final result.
