Dollar Cost Averaging Calculator
Calculate your DCA results and average cost basis
Uses & Examples
When to Use This Tool
- Planning a dollar cost average schedule for a stock or ETF you believe in long term
- Calculating your average cost basis after multiple buys at different prices
- Comparing lump sum vs DCA — see how spreading buys reduces timing risk
- Setting up a monthly investment plan and projecting total shares accumulated
Worked Example
Worked Example
Invest $500/month for 12 months | Avg price estimate: $50/share
Total invested: 12 × $500 = $6,000
Shares accumulated: 120 shares
Average cost basis: $50.00/share
Real DCA usually beats this because you buy more shares when prices dip.
