Introduction
Stock Market Average Calculator is one of the most practical tools for retail investors in India. Whether you are a beginner or an experienced trader, calculating the average share price after multiple purchases can often feel confusing.
Many of us, when investing in companies like Reliance, Infosys, HDFC Bank, Tata Power, or SBI, often buy in parts—sometimes at higher prices, sometimes at lower ones. In such cases, finding the true average cost per share is essential to understand whether you are making profits or facing a loss.
Instead of struggling with pen-paper calculations or building complicated Excel sheets, this Stock Market Average Calculator can instantly give you the correct answer. With just a few inputs, you can find your average buy price per share, total units, and total investment amount.
This article will explain everything in detail—what average price means, why it is important, how to calculate it, and how you can use our calculator effectively to improve your investment journey.
What is an Average Price in the Stock Market?
In stock market terms, the average price is the weighted average cost per share, calculated by dividing your total investment amount by the total number of units purchased.
👉 Simply put, if you bought shares at different prices, the average price shows the true cost per share after combining all purchases.
Example 1 – Simple Calculation
- First, you buy 100 shares of Tata Power at ₹200 each = Investment of ₹20,000
- Later, you buy 50 more shares at ₹150 each = Investment of ₹7,500
- Total Investment = ₹27,500 for 150 shares
👉 Average Price = ₹27,500 ÷ 150 = ₹183.33 per share
This means that no matter whether you bought at ₹200 or ₹150, your effective average cost is ₹183.33 per share.
Why is the Stock Market Average Calculator Important?
Indian investors often follow the strategy of averaging down (buying more shares at a lower price to reduce average cost) or averaging up (buying more shares at a higher price when they believe in long-term growth).

Example Calculation Using the Calculator
Let’s assume:
- You buy 100 shares of SBI at ₹600 = ₹60,000
- You buy 50 shares of SBI at ₹550 = ₹27,500
Now, total investment = ₹87,500 for 150 shares.
👉 Average Price = ₹87,500 ÷ 150 = ₹583.33 per share
This average helps you know the exact cost you paid, so you can compare it with the current market price.
Formula Behind the Calculator
If you want to calculate manually, here’s the formula for stock average price:
Average Price = (Total Amount Invested) ÷ (Total Units Purchased)
Where,
- Total Amount Invested = (Units1 × Price1) + (Units2 × Price2)
- Total Units Purchased = Units1 + Units2
This formula can be extended for 3rd, 4th, or multiple purchases as well.
