Red Cedar Wealth Advisors

Retirement Calculator

A free retirement stress test built by John Koyle, AIF®, a fiduciary financial advisor at Red Cedar Wealth Advisors in Pocatello, Idaho.

This calculator runs 500 randomized Monte Carlo simulations against your actual savings, retirement age, spending plan, and account mix. It returns a single percentage showing how often your plan ends with money still in the account, then identifies where sequence-of-returns risk, tax drag, and withdrawal order would most likely break it. Running the calculator and viewing results is free and does not require an email.

The tool models sequence-of-returns risk, Roth conversion timing, tax-efficient withdrawal sequencing, and Social Security claiming strategy in one integrated 30-year projection. It is built by a fiduciary advisor for the purpose of surfacing planning gaps, so every result ties back to a specific, actionable change rather than just a projected account balance.
