Can Your Retirement Plan Survive The Unexpected?
The Dentist Money Show
· · 51 min · Hosts: Matt Mulcock, Rabih
Summary
The episode explains Monte Carlo simulations as a way to measure retirement risk under uncertainty rather than forecast a single future. The host and a guest trace the idea back to gambling and then to Stanislaw Ulam’s early work, showing how the method evolved into computer-based probability modeling used in finance, weather, and other fields where variables change constantly.
For dentists, the guest argues that Monte Carlo analysis is most useful near retirement, when income becomes more predictable and the key decisions shift to spending, taxes, Social Security, Roth conversions, selling a practice, or changing work schedules. The simulation can show the probability of success, the odds of running out of money, and how different trade-offs affect outcomes, but it does not solve qualitative questions like lifestyle preference or emotional comfort.
The host and guest also stress the limits: assumptions can be gamed, human behavior is hard to model, and the tool should not become a spreadsheet obsession. Their bigger point is that retirement planning is a process, not a one-time calculation, and that the best use of simulation is to support better decisions over time.
Key takeaways
- The guest says Monte Carlo simulation is best understood as a probability tool, not a crystal ball for predicting retirement.
- The host argues the method is most useful for dentists within about 7 to 10 years of exiting, when retirement decisions become concrete.
- The guest says the model is strongest for comparing trade-offs such as selling a practice, dropping a clinical day, or changing spending.
- The host warns that sequence of return risk can create very different retirement outcomes even when long-term average returns are the same.
- Both speakers say the biggest limitations are assumptions, gamed inputs, and human behavior, which the simulation cannot fully capture.

“you're quite literally modeling how likely you are to run out of money by the time you die”
“Job's not finished. It becomes a completely different game with completely different rules when you get into what we'd call distribution mode”
