Frequently Asked Questions
How many children can I track?
The Ultimate template supports planning for multiple children. Use one row per child in the Setup sheet and the projections update for each.
What tuition inflation rate should I use?
College costs have historically risen 5% to 8% per year, faster than general inflation. Adjust the inflation input based on whether you are targeting in-state, out-of-state, or private institutions.
What does the 529 vs Taxable sheet compare?
It models the same contribution growing in a tax-advantaged 529 plan versus a taxable brokerage account, accounting for ongoing tax drag and the eventual after-tax balance available for tuition.
How does the contribution planner help?
The sensitivity grid shows the projected final balance across a matrix of monthly contributions and expected return rates, so you can see how a small change to either side moves the outcome.
Can I plan for graduate school?
Yes - extend the enrollment year and target cost to cover graduate years, or duplicate the file to model undergrad and graduate plans separately.
