1. What is Dollar-Cost Averaging?

Dollar-cost averaging is an investment strategy where an investor divides up the total amount to be invested across periodic purchases of a target asset to reduce the impact of volatility on the overall purchase. The average cost per share is calculated as the total amount invested divided by the total number of shares purchased.

2. How Does the Calculator Work?

The calculator uses the dollar-cost averaging formula:

\[ \text{Average Cost} = \frac{\sum (Cost_i \times Shares_i)}{Total\ Shares} \]

Where:

$ Cost_i $ — Cost per share for transaction i ($)
$ Shares_i $ — Number of shares purchased in transaction i
$ Total\ Shares $ — Sum of all shares purchased across all transactions

Explanation: This formula calculates the weighted average cost per share based on all your investment transactions.

3. Benefits of Dollar-Cost Averaging

Details: Dollar-cost averaging helps reduce investment risk through regular, fixed-amount investments regardless of market conditions. It eliminates the need to time the market and can lower the average cost per share over time.

4. Using the Calculator

Tips: Enter the number of transactions you've made, then input the cost per share and number of shares for each transaction. All values must be positive numbers.
