Representative cost scenario
Compare the same hypothetical online ASX buy across platforms using verified calculator-ready pricing rules. This is an estimate of brokerage only; taxes, market movement, spreads, subscriptions and other costs are excluded unless the applicable brokerage rule explicitly includes them.
| Platform | Status | Estimated brokerage | Rule used | Evidence |
|---|---|---|---|---|
| CMC Invest | Calculated | $11.00 | Standard: buy at or above $1,000 | Source ↗Verified 26/09/2026 |
| CommSec | Calculated | $19.95 | Australian shares brokerage (online, settled to CDIA or Margin Loan) | Source ↗Verified 26/09/2026 |
Scenario: online ASX buy, first eligible buy of that security today, no margin-loan settlement. Where a platform publishes named plans, the Standard plan is used, or Fixed for Interactive Brokers.
CommSec uses its online CDIA/Margin Loan settlement brokerage schedule for this representative scenario. CMC's published first-eligible-buy concession is applied only when the entered amount and conditions match its verified rule.
A platform is shown as “Not calculable” when its verified pricing cannot be determined from trade value alone. We do not convert variable pricing into an estimate by guessing.

International cost scenario
Compare verified US brokerage and AUD-to-USD conversion components for the same hypothetical investment. Components in different currencies are deliberately not added into a fake all-in total without a live exchange rate.
| Platform | Status | US brokerage | Estimated FX cost | Evidence |
|---|---|---|---|---|
| CMC Invest | Calculated | USD 0.00International shares brokerage | $30.00International orders FX spread | Brokerage source ↗FX source ↗ |
| CommSec | Calculated | USD 6.00US shares brokerage (International Shares account) | $27.50Foreign exchange conversion fee | Brokerage source ↗FX source ↗ |
Scenario: an Australian investor funds a US share purchase from AUD using the platform's verified standard pricing represented in Trading Guide.
FX is estimated from the AUD amount using the provider's published percentage where a deterministic rule exists. This is not a live currency quote.
US brokerage can be denominated in USD while FX cost is shown in AUD. We do not add those values together without an exchange rate. Per-share or variable brokerage, variable FX, pass-through charges, taxes and market movement remain excluded unless the structured rule can calculate them safely.
