Tax Drag Calculator: How Taxes Silently Melt Your Compound Wealth

When constructing a long-term investment portfolio, most retail investors look purely at expense ratios and asset performance. A silent, more destructive force is often completely overlooked: tax drag. Taxes on dividends and realized capital gains melt your compounding momentum year after year.

For instance, if your index fund yields 2% in dividends and you pay a 15% dividend tax, you lose 0.3% of your return annually. Over 30 years, this small drag costs you tens of thousands of dollars in lost compounding opportunities.

Using this simulator, you can compare a standard taxable brokerage account against a tax-free wrapper to see the exact wealth loss after 30 years.
