Dollar-Cost Averaging Calculator
Investing consistently over time is one of the most effective ways to build wealth without trying to time the market. The Dollar-Cost Averaging Calculator helps you plan regular investments into stocks, ETFs, or mutual funds by averaging your purchase price over multiple contributions. Instead of making a single lump-sum investment, dollar-cost averaging (DCA) involves investing a fixed amount at regular intervals—weekly, monthly, or quarterly—regardless of market fluctuations. This strategy smooths out volatility, reduces the emotional stress of market timing, and can lead to a lower average cost per share over the long term. Keywords like “dollar-cost averaging calculator,” “DCA calculator,” and “investment calculator” are naturally incorporated to help investors find this tool when searching for ways to automate and optimize their contribution schedules.
In real-life investing scenarios, markets can swing dramatically due to economic news, company earnings reports, or geopolitical events. For new and experienced investors alike, deciding when to buy shares can be intimidating and prone to emotional biases. By using our Dollar-Cost Averaging Calculator, you can model various investment plans in seconds—enter your periodic contribution amount, expected number of contributions, and projected average share price. The tool instantly computes your total investment, total shares purchased, and average cost per share. This empowers you to make informed decisions, compare different DCA schedules, and adjust contributions based on your financial goals. Mobile-friendly and intuitive, the calculator works seamlessly on smartphones, tablets, and desktop browsers, making it easy to plan your investments on the go.
Whether you’re funding a retirement account, dollar-cost averaging into high-growth sectors, or investing in dividend-paying stocks, this calculator serves as your go-to resource for consistent, disciplined investing. No spreadsheets, no manual arithmetic—just reliable projections that put you in control of your wealth-building strategy.

Formula for Dollar-Cost Averaging Calculator
odede> Total Investment = Contribution Amount × Number of Contributions Total Shares Purchased = ∑ (Contribution Amount ÷ Share Price at Each Interval) Average Cost per Share = Total Investment ÷ Total Shares Purchased
Here, Contribution Amount is the fixed sum you invest each period, and Number of Contributions represents how many times you invest. For each interval, you divide the contribution by the share price at that time to calculate shares acquired. Summing these shares gives Total Shares Purchased. Finally, dividing the Total Investment by the total shares yields your Average Cost per Share.
Example of Dollar-Cost Averaging Calculator
Let’s say you commit to investing $500 every month for six months into a fund whose share price varies as follows: $50, $45, $55, $48, $52, and $47. Using the Dollar-Cost Averaging Calculator:
Step 1: Calculate total investment
$500 × 6 = $3,000
Step 2: Calculate shares purchased each month
Month 1: 500 ÷ 50 = 10 shares
Month 2: 500 ÷ 45 ≈ 11.11 shares
Month 3: 500 ÷ 55 ≈ 9.09 shares
Month 4: 500 ÷ 48 ≈ 10.42 shares
Month 5: 500 ÷ 52 ≈ 9.62 shares
Month 6: 500 ÷ 47 ≈ 10.64 shares
Step 3: Sum total shares
10 + 11.11 + 9.09 + 10.42 + 9.62 + 10.64 ≈ 60.88 shares
Step 4: Compute average cost per share
$3,000 ÷ 60.88 ≈ $49.28 per share
With our calculator, you simply input the contribution amount, number of contributions, and the series of share prices. The tool instantly displays a total investment of $3,000, total shares purchased of about 60.88, and an average cost per share of $49.28. This clear output lets you understand how DCA mitigates price fluctuations over time.
