حاسبة متوسط سعر السهم

كيف يُحتسب هذا

average cost = sum(shares x price) / sum(shares)

shares x price

the amount spent on one purchase

sum(shares)

every share held, not the number of purchases

مثال محلول

Buying 10 shares at $150 ($1,500) and 15 at $120 ($1,800) is $3,300 across 25 shares, so the average cost is $132.00 — not $135.00, which is what averaging the two prices would wrongly give.

أسئلة شائعة

How do I calculate my average cost per share?

Divide the total amount spent by the total number of shares. Add up (shares x price) for every purchase, then divide by the sum of the shares — not by the number of purchases.

What is averaging down?

Buying more of a holding at a lower price than you paid, which reduces your blended cost per share. It lowers your break-even price but also increases the amount committed to a position that has fallen.

Does my broker calculate this the same way?

Brokers generally report an average cost, but tax reporting may use specific-lot identification instead, which can produce a different gain or loss. Your broker’s records are the ones that count at tax time.
