Optimizer Preview

Instead of guessing the best retirement age or when to claim Social Security, let the planner try them all. The optimizer runs your plan once for every combination of your choices, in both a normal and a down market.

What it varies

Diagram: 3 x 3 x 3 x 3 x 4 x 2 = 648 scenarios with two tax payers

A repeated age counts once, so entering 65, 65, 65 tests only 65. Everything else in the plan stays the same. Milestone dates such as YORTP1 move with each scenario's retirement and claim ages.

How the best scenario is chosen

  1. Only down-market runs are compared, because a plan that survives a bad market will survive a normal one.
  2. The run whose money lasts to the latest year wins.
  3. If several last to the end of the plan, the one with the highest net asset value in the final year wins.

The best scenario gets full year-by-year results (cash flows, balances, tax forms). Every other scenario gets one summary row; you can calculate the full results of any of them when you want to look closer.

Net asset value is in future dollars Final net asset value is in the dollars of the final year, not today's dollars. Compare scenarios with each other rather than reading the number as today's purchasing power.

Reading the optimizer results

The results are on Plan Results > Optimizer, one row per scenario:

ColumnMeaning
ScenarioScenario number (1, 2, 3...).
SS claim age / retirement age (each tax payer)The ages used in this scenario.
Roth fill bucketThe bucket filled each year, or blank for no Roth conversions.
MarketNormal Market or Down and Flat Market.
End of plan yearThe last year of the plan: the final life expectancy year, or the year the money ran out.
NAVNet asset value (all accounts) at the end of that year.

Running the optimizer again replaces the earlier optimizer results. The results of Run Plan are kept.

Read more than the winner Look at how much the final net asset value changes between neighbouring choices. If claiming at 67 or 70 makes little difference, other things (health, family, peace of mind) can decide.
