529 Plan Diagnostic Details

This post details our approach to optimizing a client’s college savings strategy using a Diagnostic. Check out our primer posts on Systematic Optimization and Diagnostics to learn more about our unique approach to financial advisory .

It’s common to wonder whether you’re saving enough for your children’s educational needs and to also be unsure what the tradeoffs are to being underfunded vs. overfunded. Our 529 Plan Diagnostic is designed to quickly give clear answers to these and other common questions while enabling us to provide a comprehensive, tailored recommendation for improving your overall approach to college savings.

As with all our Diagnostics, this structured approach ensures we are comprehensively examining your situation in a methodical way, quantifying the tradeoffs that matter, and then aligning your path forward to your unique goals. Our Diagnostics evolve over time as we identify additional analyses and Systematic Optimizations through our ongoing research and work with clients.

Systematic OptimizationsSupporting Analyses
01: Optimize contribution strategy to reach target educational funding needs– Quantify the expected future cost of college
– Model expected % of costs funded by plan based on current value of account(s) and contribution strategy
– Calculate revised contribution strategy necessary to reach target funding %
02: Define optimal investment allocation path to funding educational needs – Define target equity / bond mix by each investment year
– Identify which funds to use within the specific 529 plan to implement the investment strategy
03: Optimize 529 tax and funding benefits– Quantify the incremental tax benefits of using 529 plan to save for college costs
– Balance tax benefits with potential costs of being overfunded and other opportunity costs
04: Determine which state’s 529 plan is optimal– Calculate current plan costs vs. tax benefits
– Compare against other state plans to identify opportunities for total cost improvements
05: Develop mitigation strategy to minimize costs of being overfunded (if plan will be overfunded) – Quantify the incremental costs of being overfunded
– Reduce costs through direct mitigation (i.e. Roth Rollover, Beneficiary Updates)
– Further reduce costs through tax rate management
