Quick Answer / TL;DR

• Commission basics: U.S. retail promotions often show $0 commission. Elsewhere expect $0.0049 per share for stocks priced ≥ $1, and $0.0005 per share for stocks < $1. Minimum commission per order commonly $0.99.
• Platform fee basics: Typical platform fees are $0.005 per share (≥ $1) or $0.0005 per share (< $1), with per‑order minimums like $1. Some markets use percentage fees such as 0.99% capped at $0.99 per order.
• Additional charges: SEC fee on sales ≈ $0.0000206 per dollar of sale proceeds (cap ≈ $9.79 per trade). Options commonly cost ≈ $0.65 per contract, with order minimums.
• Actionable start: Combine small orders to exceed minimums. Pick $0 commissions where eligible. Avoid many tiny orders to lower effective fee percentage.

Commission fee basics — $0.0049/share and $0.99 minimum

Define the commission. Commission is the fee the broker charges per trade. Use it when estimating trade costs.
Expect two common per‑share tiers: $0.0049 per share for stocks priced at $1 or higher, and $0.0005 per share for stocks priced below $1. Apply these rates across many moomoo regions unless a promotion applies.
Apply a per‑order minimum. moomoo commonly enforces a minimum commission of $0.99 per order. That minimum overrides a smaller per‑share result.
Calculate examples:

• Buy 100 shares at $10. Per‑share commission = 100 × $0.0049 = $0.49. Minimum $0.99 applies. Final commission = $0.99. Effective fee = $0.99 / $1,000 = 0.099%.
• Buy 1,000 shares at $10 (trade value $10,000). Per‑share commission = 1,000 × $0.0049 = $4.90. No minimum applies. Final commission = $4.90. Effective fee = $4.90 / $10,000 = 0.049%.
• Buy 2,000 shares at $0.50 (trade value $1,000). Per‑share commission = 2,000 × $0.0005 = $1.00. Minimum $0.99 already met. Final commission = $1.00.

Use these rules:

• Apply per‑order minimum once per order, not per fill.
• Expect rounding to the nearest cent.
• Use larger orders to dilute fixed minimums.

Watch out for: placing multiple small orders. Each order can trigger a separate $0.99 minimum, raising your effective cost.

Per‑share and per‑order platform fees — $0.005/share and $1 minimum

Define platform fees. Platform fees are charged by the platform on top of commission. Treat them as a second, separate cost.
Typical platform fee tiers match commission tiers. Expect $0.005 per share for stocks ≥ $1 and $0.0005 per share for stocks < $1. Expect a platform fee minimum commonly set at $1 per order.
Combine commission and platform fee math. Use these concrete examples:

• Trade 100 shares at $10 (value $1,000): platform fee = 100 × $0.005 = $0.50 → minimum $1 applies → platform fee = $1. Commission in previous section was $0.99. Total upfront cost = $0.99 + $1 = $1.99.
• Trade 1,000 shares at $10 (value $10,000): platform fee = 1,000 × $0.005 = $5.00. Commission = $4.90. Total fees = $9.90. Effective fee = $9.90 / $10,000 = 0.099%.
• Trade 2,000 shares at $0.50 (value $1,000): platform fee = 2,000 × $0.0005 = $1.00. Commission = $1.00. Total upfront = $2.00.

Use the following checklist when you plan:

• Check per‑share rate: $0.005 or $0.0005.
• Check platform fee minimum: commonly $1 per order.
• Add commission minimum: commonly $0.99 per order.
• Apply rounding rules to the nearest cent.

Watch out for fee stacking. Commission and platform fee minima both apply. Small orders pay a higher percentage cost.

Regional fee variations — $0 commission, $0.0049/share, $0.99 min (U.S., CA, SG, MY)

Expect material regional differences. Check your account country and eligible markets. Review promotions and local fee tables.

United States (U.S.)
– Many U.S. retail accounts see $0 commission promotions for trading U.S. stocks. Promotion availability depends on account type.
– Even with $0 commission, expect regulatory fees on sales. SEC fee ≈ $0.0000206 per dollar of sale proceeds. SEC fee is calculated on the sell leg only.
– Example: sell $1,000 of stock → SEC fee ≈ $1,000 × 0.0000206 = $0.0206 (≈ $0.02). Maximum SEC fee per trade is about $9.79.

Canada (CA)
– Expect commission tiers in USD or CAD equivalents: $0.0049 per share for stocks ≥ $1, and $0.0005 per share for stocks < $1. Minimum commission ≈ $0.99 per order.
– Platform fees often mirror per‑share numbers: $0.005 per share with $1 minimum.
– Example: buy C$500 worth of a U.S. stock via a Canadian account. Commission and platform minima may apply in USD or in local currency conversion.

Singapore (SG)
– Some SG accounts display $0 commission for equities but use a platform fee expressed as a percentage.
– Common SG platform fee: 0.99% of transaction amount, capped at S$0.99 per order.
– Example: buy S$100 of stock → platform fee = min(0.99% × S$100, S$0.99) = S$0.99 (cap binds).
– Options may have contract fees such as S$0.30 per contract.

Malaysia (MY)
– Some MY fee schedules use a percentage commission: 0.03% of transaction amount, rounded up to the nearest $0.01 per order.
– Platform fee often listed as $0.99 per order.
– Example: buy RM1,000 worth → commission = 0.03% × RM1,000 = RM0.30; platform fee = RM0.99; total = RM1.29.

Comparison table — Quick regional summary

Use this regional checklist:

• Verify currency: USD, CAD, SGD, or MYR conversions matter.
• Check whether your account is eligible for $0 commission promotions.
• Confirm platform fee type: per‑share or percentage.

Watch out for: promotional language. “$0 commission” can hide platform fees, exchange fees, or regulatory charges.

Options, contracts, and non‑retail order charges — $0.65/contract and $0.01 per side

Handle options separately. Options use per‑contract pricing. Do not expect per‑share math here.
Expect a common per‑contract commission: $0.65 per contract. Expect a per‑order minimum such as $1.00. Example math:

• Buy 2 options contracts at $0.65 each → fee = 2 × $0.65 = $1.30 → above $1 minimum → final = $1.30.
• Buy 1 contract → fee = $0.65 → if minimum $1 applies, total = $1.00.

Account classification affects fees. High‑frequency or large order users may be classified as non‑retail by upstream partners. Non‑retail rules commonly include:

• Stock/ETF commission for non‑retail: $0.0049 per share, min $0.99 per order.
• Options non‑retail commission: $0.65 per contract, min $1.99 per order in some schedules.
• Notification: moomoo typically notifies you before reclassification.

Small per‑contract micro fees exist. Outside introductory periods you may see low surcharges such as $0.01 per side per contract. Apply rounding rules: contract quantities round up to the nearest whole contract for fee math. Example:

• 3.2 contract equivalent → rounded to 4 contracts → fees apply on 4 contracts.

Use this options checklist:

• Check per‑contract rate: often $0.65.
• Check per‑order minimum: often $1.00 or $1.99 for non‑retail.
• Watch for $0.01 per side charges outside promo windows.
• Expect rounding up of contract counts.

Watch out for: event contract promos. Introductory trades can be $0 commission temporarily. Expect fees to return after the introductory window.

Calculating total cost: 2 detailed trade examples — 100 shares and 2,000 micro‑shares

Example 1 — 100 shares at $10 (trade value $1,000)
– Commission: 100 × $0.0049 = $0.49 → apply $0.99 minimum → commission = $0.99.
– Platform fee: 100 × $0.005 = $0.50 → apply $1 minimum → platform fee = $1.00.
– Other charges: no SEC fee on buy leg. If you later sell, SEC fee on sell ≈ $0.0000206 per $1 of proceeds.
– Total upfront cost = $0.99 + $1.00 = $1.99.
– Effective total fee percentage = $1.99 / $1,000 = 0.199%.

Breakdown steps to follow:
1. Multiply shares by commission rate: 100 × $0.0049.
2. Compare result to $0.99 minimum.
3. Multiply shares by platform rate: 100 × $0.005.
4. Compare result to $1 minimum.
5. Sum figures and retain cents via rounding.

Example 2 — 2,000 shares at $0.50 (trade value $1,000)
– Commission: 2,000 × $0.0005 = $1.00 → minimum $0.99 satisfied → commission = $1.00.
– Platform fee: 2,000 × $0.0005 = $1.00 → platform minimum $1 applies but already met → platform fee = $1.00.
– Other charges: no SEC fee on buy leg. If you sell later, SEC fee on sale proceeds ≈ $0.0000206 × $1,000 = $0.02.
– Total upfront cost = $1.00 + $1.00 = $2.00.
– Effective total fee percentage = $2.00 / $1,000 = 0.20%.

Compare both trades:
– Both trades have the same trade value: $1,000.
– Trade A uses 100 shares at $10; total fees = $1.99.
– Trade B uses 2,000 micro‑shares at $0.50; total fees = $2.00.
– The per‑share mix changes how minima apply.

Use this calculation checklist:
– Always compute commission and platform fee separately.
– Apply each minimum once per order.
– Add regulatory fees at sell time: SEC fee ≈ $0.0000206 per dollar.
– Round to nearest cent.

Watch out for: fractional or multiple fills. The minimum applies per order, not per fill. But some clearing partners may allocate fees per fill if the order is routed differently.

Practical tactics to lower your total fees

Combine small orders. Trade once for 500 shares instead of five orders of 100 shares.
Dilute fixed minimums. Example: five $0.99 minima → $4.95 extra. Combine to avoid these costs.
Use promotional eligibility. If you qualify for $0 commission in your market, route eligible trades there. Promo example: $0 commission for U.S. stocks for eligible U.S. residents.
Choose order sizes that outrun minima. For stocks priced ≥ $1, run the math: the per‑share commission breakeven for $0.99 minimum is 203 shares (203 × $0.0049 ≈ $0.9947 → rounds to $0.99 or $0.99 applies). For platform fee $1 minimum at $0.005/share, breakeven is 200 shares (200 × $0.005 = $1.00).
Watch order type impacts. Use limit orders to control price slippage. Use market orders when immediate execution justifies the fee.
Check for account classification. If your activity is above 50 orders per day or very frequent, ask moomoo whether you might be reclassified as non‑retail. Non‑retail escalates commission.
Monitor exchange and regulatory fees. SEC fee on sale ≈ $0.0000206 per $1 of proceeds, capped near $9.79. Add exchange fees on some products like futures and crypto.
Negotiate or upgrade. Ask about volume discounts if you trade thousands of orders. Some liquidity agreements or pro accounts offer lower per‑share or per‑contract fees.

Key tactical numbers to remember:
– $0.0049 per share for stocks ≥ $1.
– $0.0005 per share for stocks < $1.
– $0.005 per share platform fee for ≥ $1.
– $0.99 minimum commission per order.
– $1 minimum platform fee per order.
– $0.65 per options contract.
– $0.0000206 per $1 on sales (SEC fee).
– 200–203 shares breakeven for platform and commission minima.

Closing

Act now to lower your fees. Check your account country and promotion eligibility. Calculate commission and platform fees separately. Combine orders to dilute $0.99 and $1 minima. Track options contract counts and per‑contract fees. Monitor sell‑side regulatory fees like the SEC charge of about $0.0000206 per $1 of proceeds. Review monthly statements for any reclassification notices. Test a few planned trades in small size, then scale to save cents that add up to dollars.
