Forex Broker Cost Calculator: Compare 29 ASIC Brokers

How to use this calculator

Enter the standard lots you trade in a typical month and pick the account style. Raw ranks brokers on our measured 8-pair average spread plus their published round-turn commission; Standard ranks commission-free accounts on their EUR/USD spread alone. Every broker name links to its full review, and brokers we cannot rank fairly appear beneath the table with the specific reason.

Volume is the input that changes the order. Commission is a fixed per-lot cost while spread cost scales with the spread itself, so a broker with a tight spread and higher commission overtakes a cheaper-commission rival as volume grows. Run your own number rather than accepting a ranking computed at someone else's.

How the costs are calculated

Monthly cost = (average spread in pips x pip value at your volume) + (round-turn commission per lot x lots). Spread figures come from our May to June 2026 8-pair measurement (rolling 24-hour captures, IceFX SpreadMonitor, London VPS); commissions come from each broker's published schedule, and USD-denominated commissions convert at current rates, marked with an asterisk in the table. The full capture method is on our methodology page.

Pip value uses EUR/USD as the proxy for the 8-pair average, since the measurement basket is USD-quoted majors; that keeps the conversion honest without inventing a per-pair volume split. Where a broker prices differently across platforms, the table footnotes it rather than averaging incomparable schedules.

What the ranking does not include

Three real costs sit outside this table. Overnight financing (swap) varies by broker, direction and holding period, and matters only for positions held past rollover. Currency-conversion fees apply when funding an AUD account from elsewhere or trading products settled in other currencies. Inactivity and withdrawal fees vary by broker and usage pattern. Each is covered in the individual broker reviews rather than baked into a single number here.

The ranking also excludes execution quality: slippage on a fast market can cost more than the spread itself. Our lowest spread broker guide pairs the same measured spreads with execution-speed testing for the brokers where we have it.

Raw vs standard accounts in this tool

Raw accounts quote near-interbank spreads and charge an explicit commission; standard accounts widen the spread and charge none. At A$14.27 per pip per standard lot, the crossover point is simple arithmetic: a commission of A$7.00 round-turn equals about half a pip, so a raw account wins whenever its spread advantage over the standard alternative exceeds that. High-volume traders almost always land on raw pricing, which is why it is the default view. The commission side of that trade-off is ranked separately in our lowest commission broker guide, and the overall picks across all costs are in the best forex brokers in Australia guide.
