Annual Drag Across Tax Brackets

Assumptions

· Turnover drag assumes average gain per sale = 15% of position value × turnover % × LTCG rate

· Roth scenario: gross return minus expense ratio only, no tax on growth or exit

· State income taxes not included · NIIT (3.8%) not included unless selected
