How much can you save with robo advisors versus traditional advisors?
The cost advantage of robo advisors becomes clear when examining real numbers. Traditional financial advisors typically charge 1-2% of assets under management, while robo advisors average just 0.25%. Let's examine the long-term impact:
20-Year Cost Comparison ($100,000 Initial Investment)
- Traditional Advisor (1.5% fee): $124,000 in fees
- Robo Advisor (0.25% fee): $26,000 in fees
- Difference: $98,000 more in your pocket
These calculations assume 7% annual returns and don't include the additional benefits of tax-loss harvesting, which Vanguard research shows can add 0.5-1% in annual after-tax returns.
