What You Can Do

You conduct rigorous retirement income adequacy analyses that evaluate whether a client's projected retirement assets will sustain their desired lifestyle across realistic market conditions, inflation trajectories, and longevity scenarios. The skill structures three-pronged analysis: deterministic baseline scenarios, stochastic modeling with sequence-of-returns analysis, and contingency planning with decision triggers. You translate complex probability distributions into comprehensible client language while maintaining analytical rigor for compliance documentation and fiduciary defense.

Features

Deterministic baseline scenario modeling

run conservative, moderate, and aggressive assumptions to establish income sufficiency baseline

Stochastic Monte Carlo analysis

model thousands of market outcome sequences to calculate success probability and sequence-of-returns risk exposure

Longevity risk assessment

project across multiple life expectancy scenarios (actuarial, optimistic, pessimistic) to stress-test spending sustainability

Inflation impact modeling

apply variable inflation trajectories to both spending needs and investment returns across retirement timeline

Withdrawal strategy evaluation

compare fixed-dollar, percentage-based, and dynamic withdrawal approaches to identify optimal spending patterns

Stress-testing framework

evaluate impact of early retirement, major expenses, market downturns, or spending increases on plan viability

Decision trigger development

establish measurable monitoring thresholds that signal when plan adjustments become necessary

Client-ready visualization templates

generate comprehensible charts and summary reports suitable for client presentations and regulatory documentation

Example Output

Example 1: Retirement Readiness Summary

Client has $1.2M in investable assets, plans to retire in 7 years at age 62 with $80K annual spending need. Analysis shows:

  • Deterministic baseline (4.5% return, 2.5% inflation): 94% success probability
  • Monte Carlo modeling (10,000 scenarios): 87% success probability through age 95
  • Sequence-of-returns analysis: 12% of worst-case scenarios lead to portfolio depletion by age 85
  • Recommendation: Increase retirement age by 2 years OR reduce spending to $72K OR shift allocation to 65/35 equity/bonds

Example 2: Stress Test Output

If market declines 30% in year one of retirement: 78% success probability (vs. 87% baseline). If client increases spending to $95K: 61% success probability. Decision trigger: If portfolio declines below $900K in first 5 years, implement $8K annual spending reduction.

Example 3: Longevity Scenario Comparison

Actuarial life expectancy (age 92): 95% success. Optimistic longevity (age 98): 82% success. Pessimistic (age 105): 71% success. Recommendation focuses on plan durability beyond age 95.
