What This Calculates

Projected average price and total planned allocation.

The calculation runs locally in your browser. Values are not submitted to johnnyji.dev. Results are rounded for display, so use provider statements or full-precision records when the number affects accounting, tax, or live order execution.

Formula

Projected average = (current cost + planned cost) / (current quantity + planned quantity)

Example

A current 10-unit position at 100 with three planned 2-unit buys at 95, 90, and 85 becomes 16 units with a projected average of 94.38.

Notes Before You Use It

  • DCA reduces timing pressure, but it can increase exposure to a falling asset.
  • Decide the maximum total allocation before starting the plan.
  • Keep a separate invalidation point for trades that are not long-term investments.

FAQ

Does DCA guarantee profit?

No. DCA is an execution method, not a return guarantee. It can reduce entry timing risk while increasing total exposure.

How many planned orders should I use?

Use enough orders to match your risk plan and exchange fee structure. More orders are not automatically better.

Can I use uneven order sizes?

Yes. Uneven size is common when a trader wants larger buys at lower prices.
