How do I model dollar-cost averaging vs lump sum investing side-by-side in PortfolioPilot?

Lump sum vs dollar-cost averaging (DCA) is a personal decision based on your risk tolerance and comfort with timing. PortfolioPilot doesn't prescribe one over the other, but the Retirement planner lets you model both side-by-side: a one-time life event for the lump-sum case, and a recurring custom payment in Money in & out for the DCA case.

To model lump sum investing:

  1. Open Retirement planner - Life events tab - + Add life event.
  2. Select Inheritance or Custom event as the event type, set Wealth impact to Increase, and enter the full amount and the year you'll deploy it. The planner treats it as a single deployment.

To model DCA:

  1. Open Retirement planner - Money in & out tab - + Add payment - Custom payment.
  2. Enter the monthly investment amount with the start and end dates of the DCA window (e.g. 3 years from now).

To compare timing trade-offs ("all in now vs spread over 3 years"), save each plan as a what-if scenario and switch between them on the projection chart. You can also ask the AI Assistant directly: "Should I invest my $200,000 all at once or spread it over 3 years?"
