How many more shares at what price it takes to pull your average down to a chosen figure
Estimates only, not financial advice. What you type stays on your device. Updated on 24 Oct 2026.Buying more of something that has fallen lowers the average price of the holding, and the useful question is how much more. Enter what you hold, the average you want to reach and the price you would buy at, and the answer comes back as a share count and a rupee cost. Buying at or above the target cannot reach it, and the page says that rather than returning a negative number.
Enter the "Quantity" and "Price each" of every buy you already hold.
"Work out what it would take to move the average" is already switched on.
Enter the "Average you want" and the "Price you would buy at".
Read how many more shares to buy and what they cost; a price at or above the target cannot reach it.
Anyone who has bought the same share twice has an average price, and almost nobody can state it. The reason is that the obvious method is wrong. Adding the prices together and dividing by how many times you bought treats a ten-share nibble and a nine-hundred-share commitment as equals, and they are not equals: each purchase counts in proportion to the money behind it.
The correct sum is the one this page does. Add up what every purchase cost, add up how many shares it bought, and divide the first by the second. That single figure is the price the whole holding really cost, and it is the number that decides whether the position is up or down today.
There is a second question underneath the first, and it is the one people are usually really asking: how much more would I have to buy, and at what price, to bring the average down to a particular figure? That is solved here too. Enter the target and the price you could buy at and the answer is a share count and a cost. Buying at or above the target cannot reach it, and the page refuses rather than returning a negative number that reads like an instruction to sell.
The rest of the article, and all 7 questions about Stock Average Calculator, are on the Stock Average Calculator page.
Take the shares you hold, multiply by the gap between your current average and the target, then divide by the gap between the target and the price you would pay. Holding 100 at 190 and aiming for 150 while buying at 100 needs 80 more shares, costing 8,000.
Brokerage, STT, stamp duty, exchange charges and GST all raise what a purchase actually cost, so the real cost per share is a little above the figure here. This page deliberately leaves them out because they differ by broker and segment; the Brokerage Calculator adds them with each charge sourced.
Averaging down lowers the price at which the holding breaks even, but it does not recover money already lost; it puts more money at risk in the same share. A position 4,000 down stays 4,000 down the moment more shares are bought. The break-even price falls; the loss does not.
A split or bonus multiplies the share count without adding money, so the average falls in exact proportion: 100 shares at 190 become 200 at 95 after a 1:1 bonus. Enter the extra shares as a purchase at a price of zero and this page produces the same figure.
