About this calculator
How the average price is worked out
Your average price is not the average of the prices you paid. It is weighted by quantity: the total amount you put in divided by the total number of shares you hold. Buying 10 shares at ₹1,500 and 100 at ₹1,000 gives an average near ₹1,045, not ₹1,250, because the larger purchase carries far more weight.
The page takes every purchase, works out the weighted average, and then compares it with the current price to show your profit or loss in rupees and as a percentage.
Averaging down, carefully
Buying more of a falling stock lowers your average and reduces the rise needed to break even. It also increases how much you have riding on a single company that the market is repricing downwards. Lowering the average does not make the position better; it only makes the arithmetic of recovery easier.
A question investors often ask themselves is whether they would buy the stock today, at this price, if they did not already own it. Each extra purchase is a fresh decision, and the price you paid earlier does not change what the company is worth.
What the figures leave out
Brokerage, STT, exchange charges, stamp duty and GST all raise your real cost, and the same charges apply again when you sell. On small trades these can add up to a noticeable share of the gain. Dividends received work the other way and reduce your effective cost.
Common questions
How do I calculate the average price of a stock bought at different prices?
Add up the total amount invested across all purchases and divide by the total number of shares. The result is weighted by quantity, so bigger purchases move the average more.
How much does a stock need to rise to recover a loss?
More than it fell, because the rise starts from a smaller base. A 30% fall needs a 42.9% rise; a 50% fall needs 100%. The calculator shows the figure for your position.
Should I average down on a losing stock?
This page shows what averaging down does to your break-even price, not whether it is wise. It lowers the rise needed to recover, and it also increases how much you have riding on one company whose price is falling.
