Tax Drag AccumulationImprove planning safety margin

Utilize tax-advantaged accounts (such as IRAs or 401ks) to shelter annual compound interest from tax drag.

Taxes paid on accrued interest reduce overall compounding velocity.

Low Interest Compounding LeverageMinimize lifetime interest expenses

Increase annual yield rate or extend savings horizon so compound interest accelerates total wealth accumulation.

User contributions make up over 85% of total ending balance, indicating interest growth is doing limited work.
