A robo-advisor is an automated investment management service. You answer questions about goals, risk tolerance, and timeline; the platform constructs a diversified portfolio of low-cost ETFs and manages it on an ongoing basis with automatic rebalancing, tax-loss harvesting, and other optimizations. The services charge 0.25–0.40% of assets under management — meaningful, but small compared to traditional advisors.
The honest question is whether the value provided exceeds the cost, and for whom. This page is about what robos actually do, the alternatives, and where the automation is worth paying for.
The standard robo-advisor service includes:
What robos do not do:
The product is investment management — a narrower scope than a financial planner.
| Service | AUM fee | Notes |
|---|---|---|
| Betterment | 0.25%–0.65% | Standard 0.25%; premium tier with human advisor at 0.65% |
| Wealthfront | 0.25% | Direct indexing for accounts >$100K, software-only |
| Schwab Intelligent Portfolios | 0% AUM | Fee comes from cash holdings (which are higher than competitors) |
| Fidelity Go | 0% under $25K, 0.35% above | Tiered model |
| Vanguard Digital Advisor | 0.20% | Vanguard underlying funds, lower cost than independents |
The fee structures vary in important ways. "Free" robos (Schwab Intelligent Portfolios) typically generate revenue through cash allocations earning less than market rates — economically equivalent to a fee but presented differently.
For 0.25% AUM, what you actually get vs. doing it yourself:
The tax-loss harvesting is often the strongest argument. Done well, it can save 0.50–1.50% in taxes annually for taxable account holders in higher brackets — more than offsetting the AUM fee.
Tax-loss harvesting at that scale produces real savings. Robos do TLH automatically and systematically; doing it yourself requires monitoring and judgment.
Higher brackets amplify the value of TLH. A 35%+ federal bracket plus state tax means each $1,000 of harvested losses is worth $400+.
The honest version: many people who say they will rebalance annually do not. If a 0.25% fee buys you actual rebalancing, automatic deposits, and disciplined tax-loss harvesting that you would not otherwise execute, the fee is well-spent.
The robo handles rebalancing, contribution timing, and TLH. You log in occasionally to check progress. For investors who want minimum involvement, this is a reasonable trade.
Most of the robo's value comes from tax-loss harvesting in taxable accounts. In a 401(k) or IRA, that benefit does not exist. A target-date fund in your retirement account replicates most of what a robo does at lower cost.
A diligent investor with a written IPS, automatic monthly contributions, and disciplined annual rebalancing does not need a robo. The marginal value the robo provides is small relative to the fee.
A 0.25% AUM fee on a $1M portfolio is $2,500/year. That is real money. At larger sizes, even efficient robos become expensive vs. DIY.
If you want a specific allocation that the robo does not offer (heavy small-cap value tilt, no international, specific REIT overweight), DIY is required.
For an investor who wants robo-like outcomes without paying a robo:
The total time investment is 1–2 hours per year. The cost saving vs. a 0.25% AUM robo is meaningful at portfolio sizes above $100K.
The honest variant: many people who plan to do this do not actually do it consistently. If you have a track record of rebalancing diligently, DIY wins. If not, a robo's discipline may be worth the fee.
For investors who want some automation without paying a full robo fee:
A single target-date fund handles allocation, rebalancing, and the glide path. No fee beyond the underlying expense ratio (0.05–0.15%). Loses tax-loss harvesting but otherwise does what a robo does.
For tax-advantaged accounts, this is often the cleanest answer.
Use a target-date fund for your 401(k) and IRA; manage the taxable account yourself with broad-market ETFs. Capture the tax-loss harvesting in taxable manually a few times per year.
For the highest-leverage automation: robo handles taxable (where TLH provides value); target-date fund handles tax-deferred (where TLH does not).
