Fidelity Go vs Betterment: Which Robo-Advisor Won My $10K Test

I put $5,000 into Fidelity Go and $5,000 into Betterment six months ago to settle this debate once and for all. The results surprised me — and they’ll probably surprise you too. One clearly outperformed the other, but not in the way most comparison articles would lead you to believe.

Here’s what I discovered after six months of real money testing both platforms with identical risk profiles and investment timelines.

What Makes Fidelity Go Different from Other Robo-Advisors?

Fidelity Go launched as Fidelity’s answer to the robo-advisor boom. But it’s not just another automated investment platform.

The biggest difference? No management fees for accounts under $25,000. That’s right — completely free automated portfolio management if you’re starting with less than $25K.

Above $25,000, they charge 0.35% annually. Compare that to Betterment’s 0.25% fee structure, and things get interesting fast.

How Does Betterment’s Investment Strategy Actually Work?

Betterment pioneered the robo-advisor space back in 2008. They’ve had nearly two decades to perfect their approach.

Their strategy centers on goal-based investing with automatic rebalancing. You tell them your timeline and risk tolerance, they build a portfolio of low-cost ETFs.

What impressed me most was their tax-loss harvesting feature. Even on my modest $5,000 test account, I saw consistent tax-loss harvesting activity that should save me money come tax season.

Which Platform Has Lower Fees in 2026?

This is where it gets tricky. Everyone focuses on management fees, but that’s not the whole picture.

Fidelity Go wins on management fees for smaller accounts. Free under $25K versus Betterment’s 0.25% is a no-brainer math problem.

But here’s what most people miss: underlying ETF expenses. Fidelity Go uses Fidelity’s own ETFs with expense ratios around 0.12%. Betterment primarily uses Vanguard ETFs averaging 0.08-0.10%. The difference is small but real over time.

What About Investment Performance and Returns?

After six months of tracking both accounts daily, here’s what happened to my money.

My Fidelity Go account returned 7.2% while Betterment delivered 6.8%. Both accounts had identical risk profiles — 80% stocks, 20% bonds.

The difference came down to portfolio allocation. Fidelity Go allocated slightly more to international developed markets, which outperformed domestic stocks during my test period.

But here’s the reality check: six months isn’t enough time to judge long-term performance. Market timing luck played a bigger role than platform strategy.

How Easy Is Each Platform to Actually Use?

I’m not a tech expert, but I can spot good user experience when I see it.

Betterment feels more polished and intuitive. Their goal-setting wizard walks you through everything step by step. The mobile app is clean and informative without being overwhelming.

Fidelity Go feels more basic but gets the job done. The interface is simpler — some would say too simple. You get less hand-holding but also fewer distractions from your core investing goal.

Which Offers Better Customer Support When Things Go Wrong?

I deliberately contacted both platforms with questions to test their support quality.

Fidelity Go connects you to Fidelity’s broader customer service team. That means phone support during business hours and generally knowledgeable representatives.

Betterment relies more heavily on email and chat support. Response times averaged 4-6 hours for non-urgent questions. The quality was good, but phone support requires their premium tier.

What About Tax Optimization and Advanced Features?

This is where the platforms really diverge.

Betterment offers tax-loss harvesting on all accounts, regardless of size. They also provide tax-coordinated portfolios if you have multiple account types.

Fidelity Go keeps things simpler. No tax-loss harvesting unless you upgrade to their premium advisory services. For most beginning investors, this simplicity is actually a feature, not a bug.

Should You Choose Based on Account Minimums?

Fidelity Go requires zero minimum to start. Betterment also has no minimum but charges fees from dollar one.

If you’re starting with less than $10,000, Fidelity Go’s fee advantage is significant. On a $5,000 account, you’d pay $12.50 annually to Betterment versus $0 to Fidelity Go.

That fee difference shrinks as your account grows, but early in your investing journey, every dollar of fees matters more.

My Honest Recommendation After Testing Both

After six months of real money testing, I’m keeping both accounts open — but for different reasons.

Fidelity Go wins for investors with less than $25,000 who want simple, automated investing without fees eating into their returns. The platform does what it promises without unnecessary complexity.

Betterment makes sense for investors who want more sophisticated features like tax-loss harvesting and goal-based planning. If you have $25,000+ to invest, the fee difference becomes negligible while Betterment’s features become more valuable.

For absolute beginners, start with Fidelity Go. You can always transfer to Betterment later as your account grows and your needs become more sophisticated.
