Comparison
Lifetime tax per strategy
Three curves side by side, one per strategy. In a sample scenario the gap was $37,000 over 25 years.
Tax brackets
All federal brackets with visible rates
Each modeled bracket has a linked source and the date of the last update. State income tax is not modeled.
Year by year
Detailed view per year and per account
Each year shows exactly where the money comes from and what becomes tax. No summarizing.

Understand the assumptions, not just the answer
Built with financial expertise
