Stock Trading App Fees USA: Complete Cost Guide (2026)
“Zero commissions” is the most advertised feature of every major stock trading app in the USA — and it’s genuinely true for stock and ETF trades. But zero commissions is only one layer of the total cost of using a trading app. Options contract fees, expense ratios, margin rates, subscription charges, transfer fees, and regulatory fees all vary significantly across platforms and collectively determine your real cost of trading.
This guide covers every fee category, platform by platform, with real numbers — so you know exactly what you’re paying and where.
The Total Fee Stack: 8 Cost Categories
Understanding trading app fees requires looking at all eight cost categories simultaneously, not just commissions.
① Stock and ETF commissions — the per-trade charge for buying or selling stocks. Now $0 at every major US app.
② Options contract fees — the per-contract charge on options trades. Ranges from $0 to $0.65 depending on the platform. The most significant ongoing fee difference between apps for active traders.
③ Fund expense ratios — annual fees built into ETFs and mutual funds. Ranges from 0.00% to 1.00%+. The most financially significant fee for long-term investors.
④ Margin interest rates — annual interest on borrowed funds for margin trading. Ranges from approximately 6% to 13%+ depending on platform and balance.
⑤ Monthly subscription fees — recurring charges for premium features. Ranges from $0 to $12/month depending on app and tier.
⑥ Account and transfer fees — charges for transferring accounts out, broker-assisted trades, wire transfers, and paper statements.
⑦ Regulatory fees — small fees applied by regulators on every sell transaction. Unavoidable, but very small (~$0.01–$0.03 per $1,000 sold).
⑧ Crypto and currency conversion fees — spreads embedded in cryptocurrency trades and foreign currency conversions. Often the most expensive hidden cost for crypto traders.
Fee Category 1: Stock and ETF Commissions
The current standard: $0 across all major US apps.
Stock and ETF commissions are universally $0 at every major US trading platform in 2026. This is not a promotional offer — it’s the permanent baseline competitive standard. The following platforms all charge $0 to buy or sell US-listed stocks and ETFs: Fidelity, Schwab, Robinhood, Webull, Interactive Brokers (Lite), E*TRADE, tastytrade, Moomoo, SoFi, Public, Firstrade, Merrill Edge, J.P. Morgan Self-Directed, Ally Invest, and Vanguard.
Exception — IBKR Pro: Interactive Brokers’ professional tier charges per-share commissions starting at $0.0005/share (minimum $1 per order). Traders at this tier get lower margin rates and bulk options discounts in exchange, making it cost-effective for high-volume professional traders.
Regulatory fees on sell orders (unavoidable at all platforms):
Every sell order carries small regulatory fees set by the SEC and FINRA — not by the trading app. These are:
- SEC Transaction Fee: approximately $0.013 per $1,000 of proceeds
- FINRA Trading Activity Fee: approximately $0.000166 per share sold (max $8.30)
On a $10,000 stock sale: SEC fee ≈ $0.13, FINRA fee ≈ varies. These are genuinely minor — a $10,000 sale generates under $0.50 in total regulatory fees.
Fee Category 2: Options Contract Fees
This is the most important fee comparison for active options traders and the area of greatest variation between platforms.### Options Contract Fee Comparison: All Major US Apps
| Platform | Per Contract (Open) | Per Contract (Close) | Notes |
|---|---|---|---|
| Robinhood | $0 | $0 | Both open and close free |
| Webull | $0 | $0 | Both open and close free |
| Moomoo | $0 | $0 | Equity options free; index options $0.50 |
| SoFi Invest | $0 | $0 | Both open and close free |
| Firstrade | $0 | $0 | Both open and close free |
| Public | $0 | $0 | Pays rebates on options trades |
| tastytrade | $1.00 | $0 | $1 open / free close; capped $10/leg |
| Ally Invest | $0.50 | $0.50 | Below industry standard |
| Fidelity | $0.65 | $0.65 | Volume discount available |
| Schwab | $0.65 | $0.65 | No volume discount |
| E*TRADE | $0.65 | $0.65 | Volume discount at 30+ contracts/order |
| IBKR (Lite) | $0.65 | $0.65 | Minimum $1 per order |
| IBKR (Pro) | $0.65 | $0.65 | Volume discounts at high volume |
| Merrill Edge | $0.65 | $0.65 | Standard rate |
What the Options Fee Difference Actually Costs
The following table shows the annual cost of options fees at different trading volumes, comparing $0/contract vs. $0.65/contract platforms:
| Monthly Round-Trip Contracts | $0/contract Annual Cost | $0.65/contract Annual Cost | Annual Difference |
|---|---|---|---|
| 10 contracts | $0 | $156 | $156 |
| 25 contracts | $0 | $390 | $390 |
| 50 contracts | $0 | $780 | $780 |
| 100 contracts | $0 | $1,560 | $1,560 |
| 200 contracts | $0 | $3,120 | $3,120 |
For traders doing 10 contracts/month, the $156/year difference is minor. For traders doing 100+ contracts/month, saving $1,560+ annually is a meaningful ongoing impact on net returns.
The tastytrade exception explained: tastytrade’s $1 open / $0 close structure becomes superior to $0 platforms for very frequent closers at high volume. A trader opening and closing 100 contracts per month at tastytrade pays $1,200/year vs. $1,560 at $0.65 platforms — a meaningful saving despite the higher opening fee. For traders who open contracts rarely but close frequently, tastytrade’s free closing is valuable.
Fee Category 3: Fund Expense Ratios
For long-term investors, expense ratios are the most financially significant fee category — far exceeding any commission savings.
What an expense ratio is: An annual percentage of your invested assets charged by the fund, deducted automatically from fund performance. A fund with a 0.50% expense ratio costs you $50/year on $10,000 invested — silently reducing your returns year after year without appearing on any statement.
The 30-Year Cost Impact of Expense Ratios
On $50,000 invested for 30 years at 7% gross annual return:
| Expense Ratio | Final Balance | Fee Cost (vs. 0%) |
|---|---|---|
| 0.00% (Fidelity FZROX) | $380,613 | $0 |
| 0.03% (Vanguard VTI) | $369,147 | ~$11,466 |
| 0.10% (typical ETF) | $350,151 | ~$30,462 |
| 0.25% (common active fund) | $320,489 | ~$60,124 |
| 0.50% (many actively managed) | $295,628 | ~$84,985 |
| 1.00% (expensive active fund) | $252,695 | ~$127,918 |
The difference between 0.00% and 1.00% expense ratio on $50,000 over 30 years is approximately $127,918 — purely from the annual fee.
Lowest Expense Ratio Funds Available by Platform
| Platform | Lowest Available Fund | Expense Ratio |
|---|---|---|
| Fidelity | FZROX (Total Market) | 0.00% |
| Fidelity | FZILX (International) | 0.00% |
| Vanguard | VTI, VOO, BND | 0.03% |
| Schwab | SCHB, SCHF | 0.03% |
| Fidelity | FXAIX (S&P 500) | 0.015% |
| All platforms | Standard ETFs (VTI, etc.) | 0.03%+ |
Fidelity’s 0.00% expense ratio funds are available exclusively at Fidelity and represent the lowest-cost long-term stock market exposure available anywhere. No other platform — including Vanguard — offers zero-expense-ratio index funds.
Fee Category 4: Margin Interest Rates
Margin rates are the annual interest charged when you borrow money from a trading app to buy more securities than your cash balance supports. These rates vary dramatically across platforms — the most significant cost difference for leveraged traders.
Margin Rate Comparison (Balance: Up to $100,000)
| Platform | Margin Rate (up to $100K) | Notes |
|---|---|---|
| Interactive Brokers (Pro) | ~6.83% | Industry lowest retail rate |
| Robinhood (Gold) | ~7.25% | Lower with Gold subscription |
| Webull | ~8.74% | Tiered by balance |
| Firstrade | ~8.00% | Varies |
| Moomoo | ~6.8%** | Promotional rate may apply |
| Fidelity | ~8.25–10.00%+ | Tiered by balance |
| Schwab | ~12.00%+ | Higher than average |
| E*TRADE | ~12.00%+ | Morgan Stanley base rate |
The margin rate difference in dollars:
On $10,000 borrowed for one year:
- Interactive Brokers at 6.83%: $683 in interest
- Schwab at 12.00%: $1,200 in interest
- Annual difference: $517 per $10,000 borrowed
For traders who use margin regularly, choosing Interactive Brokers over Schwab saves hundreds to thousands of dollars annually depending on the margin balance maintained.
IBKR Pro’s tradeoff: IBKR Pro charges per-share commissions ($0.0005/share minimum $1) instead of the IBKR Lite $0 commissions — but delivers the lowest margin rates available to retail investors. High-volume margin traders often find IBKR Pro’s total cost lower despite the commissions.
Fee Category 5: Monthly Subscription Fees
Most trading apps have a free tier with no monthly charges. Premium tiers add features for a recurring fee.
Subscription Tiers at Major US Trading Apps
| App | Free Tier | Premium Tier | Premium Cost | Key Premium Benefits |
|---|---|---|---|---|
| Fidelity | ✅ Full features | Fidelity Go (robo) | 0.35%/yr (>$25K) | Advisor coaching calls |
| Schwab | ✅ Full features | Intelligent Portfolios Premium | $30/mo | CFP access |
| Robinhood | ✅ Core trading | Gold | $5/mo | 3% IRA match, 4.5% APY, Morningstar |
| Webull | ✅ Core trading | Premium | $14.99/mo+ | Level II data, higher IRA match |
| IBKR | ✅ Lite | Pro + data | Varies by data | Lower commissions, lower margin |
| E*TRADE | ✅ Full features | None | — | — |
| Public | ✅ Core trading | Premium | $10/mo | 5.1% APY, higher options rebates |
| Acorns | — | Personal / Family | $3/$5/mo | Basic features require subscription |
| M1 Finance | ✅ Basic | Premium | $3/mo (<$10K balance) | Waived at $10K+ |
Subscription fee math on small balances:
Acorns at $3/month ($36/year) on a $500 balance = 7.2% annual fee. This exceeds almost any reasonable investment return. Subscriptions make financial sense only when the benefits clearly exceed the cost — Robinhood Gold’s 3% IRA match on a $7,000 contribution adds $210/year in free money, making the $60/year Gold subscription a strong value for IRA contributors.
Fee Category 6: Account and Transfer Fees
These fees are easily avoided but worth knowing before choosing a platform.
Transfer and Account Fees: Major Platforms
| Fee Type | Fidelity | Schwab | Robinhood | Webull | IBKR |
|---|---|---|---|---|---|
| Account maintenance | $0 | $0 | $0 | $0 | $0 |
| Inactivity fee | $0 | $0 | $0 | $0 | $0 (Lite) |
| Full ACAT transfer out | $0 | $25 | $0 | $75 | $0 |
| Partial ACAT transfer out | $0 | $25 | $0 | $75 | $0 |
| Wire transfer (outgoing) | $10 | $25 | $0 | $10 | Varies |
| Broker-assisted trade | $32.95 | $25 | N/A | N/A | $30 |
| Paper statements | $0 (opt-in) | $0 | N/A | N/A | $0 |
ACAT transfer fees matter when switching platforms. Webull’s $75 ACAT transfer fee is the highest among major apps — charging this when you want to move your account elsewhere. Fidelity, Robinhood, and IBKR charge $0 for outgoing transfers. When switching from Webull to another platform, the receiving platform (Fidelity, Schwab) will typically reimburse up to $75 in transfer fees if you transfer a minimum amount — check the specific reimbursement offer before initiating.
Fee Category 7: Regulatory Fees (Unavoidable)
These fees are set by the SEC and FINRA and applied to all US stock sales regardless of which platform you use. No trading app can eliminate them.
SEC Transaction Fee: ~$0.013 per $1,000 in proceeds from stock sales. On a $5,000 stock sale: approximately $0.065.
FINRA Trading Activity Fee (TAF): $0.000166 per share sold, maximum $8.30 per trade. On 1,000 shares sold: approximately $0.17.
Options Regulatory Fee (ORF): Applied on all options transactions, typically $0.02–$0.04 per contract. Minor but present even on $0/contract platforms.
Practical impact: On a $10,000 stock sale, total regulatory fees are approximately $0.30–$0.50 — negligible for any investor. These fees are disclosed on trade confirmations as “regulatory fees” or “exchange fees.”
Fee Category 8: Cryptocurrency and Currency Conversion Fees
These are the most commonly overlooked and often most expensive fees for investors who trade crypto or international securities.
Crypto Spread Fees at Major Apps
Unlike stock commissions (now $0), crypto trading generates revenue through embedded price spreads — the difference between the displayed buy and sell price. You don’t see this as a separate charge; it’s built into the price you pay.
| Platform | Crypto Fee Structure | Typical Spread | On $10,000 Purchase |
|---|---|---|---|
| Robinhood | Embedded spread | ~0.5%–1.5% | ~$50–$150 |
| Webull Pay | Embedded spread | ~1.0% | ~$100 |
| Public | Embedded spread | ~1.0%–1.5% | ~$100–$150 |
| Coinbase (retail) | Transaction fee | 1.5%–3.5% | ~$150–$350 |
| Coinbase Advanced | Maker/taker | 0.0%–0.6% | ~$0–$60 |
Crypto spreads at traditional trading apps typically range from 0.5% to 1.5% — far higher than stock trading costs. On a $10,000 Bitcoin purchase, a 1% spread costs $100 in hidden fees versus the $0 you’d pay on a $10,000 stock purchase.
For frequent crypto traders: Dedicated crypto exchanges with maker/taker fee structures (Coinbase Advanced Trade, Kraken Pro) offer significantly lower costs than embedding crypto into a traditional trading app. The convenience of having crypto and stocks in one app comes at a cost in crypto execution fees.

Profile 3: Margin Trader
- $30,000 margin balance maintained
- 50 round-trip options contracts per month
| Platform | Annual Margin Interest | Annual Options Fees | Total Annual |
|---|---|---|---|
| IBKR Pro (~6.83%) | $2,049 | $780 (standard rate) | $2,829 |
| Robinhood Gold (~7.25%) | $2,175 | $0 | $2,175 |
| Webull (~8.74%) | $2,622 | $0 | $2,622 |
| Fidelity (~9.00%) | $2,700 | $780 | $3,480 |
| Schwab (~12.00%) | $3,600 | $780 | $4,380 |
Winner at this profile: Robinhood Gold — $0 options fees + competitive margin rates produces the lowest total cost. IBKR Pro wins at significantly higher trading volumes where its bulk options discounts outweigh the commission costs.
Hidden Fees to Watch
Cash drag on low-yield default positions. Many apps place uninvested cash in low-yield sweep accounts paying 0.01–0.10% APY while investing it at 4–5%. Check your default cash position and opt into a money market fund or high-yield account if available. Fidelity’s SPAXX money market fund is a common default; Robinhood Gold pays 4.5% APY; SoFi’s banking integration pays competitive rates.
Broker-assisted trade fees. Placing a trade by calling a human broker costs $25–$32.95 at most platforms vs. $0 online. Use the app for all trade execution.
Mutual fund transaction fees. Not all mutual funds trade without fees. Fidelity charges $49.95 for some non-Fidelity funds outside the no-transaction-fee list. Always verify before placing a mutual fund order at any platform.
Foreign stock trading fees. Buying international stocks directly (not through ADRs or international ETFs) carries additional currency conversion and exchange fees at most platforms. Interactive Brokers has the most competitive international trading cost structure.
Full Fee Comparison: 10 Apps Side by Side
| Platform | Stock/ETF | Options/Contract | Lowest Fund ER | Margin (~$50K) | Monthly Fee | ACAT Out |
|---|---|---|---|---|---|---|
| Fidelity | $0 | $0.65 | 0.00% | ~9% | $0 | $0 |
| Schwab | $0 | $0.65 | 0.03% | ~12% | $0 | $25 |
| Robinhood | $0 | $0 | 0.03% | ~7.25% | $0 (Gold $5) | $0 |
| Webull | $0 | $0 | 0.03% | ~8.74% | $0 (Premium $15) | $75 |

| E*TRADE | $0 | $0.65 | 0.03% | ~12% | $0 | $25 |
| tastytrade | $0 | $1/$0 | 0.03% | Varies | $0 | $0 |
| Moomoo | $0 | $0 | 0.03% | ~6.8% | $0 | Varies |
| Ally Invest | $0 | $0.50 | 0.03% | ~9% | $0 | $50 |
How to Minimize Your Total Trading App Fees
For long-term investors: Open a Roth IRA at Fidelity. Buy FZROX at 0.00% expense ratio. Enable automatic monthly contributions and dividend reinvestment. Set-and-hold. Your total annual fee: $0.
For active options traders: Use Robinhood or Webull for $0/contract options fees. The savings vs. $0.65/contract platforms compound meaningfully at 50+ contracts per month.
For margin traders: Interactive Brokers offers the lowest margin rates available to US retail investors. Compare your current margin interest against IBKR’s rates — if you borrow $50,000+ regularly, the savings frequently justify the account switch.
For crypto traders: Use dedicated crypto exchanges with maker/taker pricing (Coinbase Advanced, Kraken Pro) rather than traditional trading app crypto features. The spread difference between 0.1% maker fees and 1%+ embedded spreads adds up quickly.
For everyone: Check your default cash position. Uninvested cash sitting in a 0.01% sweep account when you could have it in a 4%+ money market fund is an unnecessary ongoing cost.
FAQ
Q: Are there truly zero fees to trade stocks in the USA? For US-listed stock and ETF trades, yes — $0 commissions are genuine and permanent at all major platforms. Small regulatory fees (under $0.50 per $10,000 traded) are unavoidable and set by the SEC and FINRA, not the platforms. For long-term index fund investors at Fidelity using FZROX, the total annual fee is genuinely $0 including expense ratios.
Q: Which trading app has the lowest fees overall? It depends on your trading style. For long-term index fund investors: Fidelity (0.00% FZROX, $0 commissions, $0 account fees). For active options traders: Robinhood or Webull ($0/contract). For margin traders: Interactive Brokers (~6.83% rate). There’s no single lowest-fee app across all categories simultaneously.
Q: What is a reasonable expense ratio for an ETF or index fund? Under 0.10% is considered excellent. 0.03% (Vanguard VTI, Schwab SCHB) is outstanding. 0.00% (Fidelity FZROX) is the best available. Expense ratios above 0.50% should be scrutinized carefully — most actively managed funds at this cost fail to outperform equivalent low-cost index funds over time.
Q: Why does Schwab charge higher margin rates than competitors? Schwab’s margin rates are set relative to its broker call loan base rate. Schwab’s core revenue model relies more heavily on net interest income from client cash than on margin interest specifically — so margin rates aren’t as aggressively competitive as at IBKR, which actively competes for active traders who use leverage.
Q: Are options fees charged on both opening and closing a position? At most platforms ($0.65 apps), yes — both opening and closing generate the per-contract fee. tastytrade charges $1 to open but $0 to close. Robinhood, Webull, Moomoo, SoFi, and Firstrade charge $0 on both sides.
