Investing in stocks often involves purchasing shares at different prices over time. This can make it difficult to know the exact average price per share you paid. The Share Average Calculator solves this problem by instantly calculating your weighted average cost per share.
Instead of manually crunching numbers, this tool takes your share prices and corresponding quantities, then quickly gives you the average share price. It’s designed to help investors make informed decisions by providing clear insights into their investment costs.

When you buy the same stock at different prices, you need to know the average cost to:
- Track your real investment cost.
- Decide the right selling point for profit.
- Manage tax planning more effectively.
- Simplify your portfolio management.
Without such a calculator, errors are easy to make, especially when handling multiple purchases.

Practical Example
Let’s say you purchased:
- 10 shares at $100 each
- 20 shares at $150 each
- 15 shares at $120 each
Step 1: Input
- Prices:
100, 150, 120 - Quantities:
10, 20, 15
Step 2: Calculation
- Total Cost = (100 × 10) + (150 × 20) + (120 × 15) = 1000 + 3000 + 1800 = $5800
- Total Shares = 10 + 20 + 15 = 45 shares
- Average Price = 5800 ÷ 45 = $128.89
Step 3: Result
- Total Cost = $5,800
- Total Shares = 45
- Average Price per Share = $128.89
This gives you a clear picture of the average cost of your investment.
