Forex Spread Cost Calculator for 33 ASIC Brokers

How to use the broker cost calculator

Start by entering the standard lots traded in a typical month and picking the account style. Each view ranks on the same eight-pair basket: Raw on the average raw spread plus round-turn commission per lot, Standard on the average spread of commission-free accounts, so the two compare like for like. The label under each spread names its source, a capture window or the word "published". Every broker name links to its full review, and brokers we cannot rank fairly appear beneath the table with the specific reason. The raw ranking is the starting point I would use because it captures the cost you actually pay on a like-for-like basis.

Volume is the input that sizes your estimate, and both total spread cost and total commission cost scale with lots, so every broker's total grows in the same proportion. With account style, exchange rates, eligible brokers and stored costs fixed, moving between any positive volumes, up or down, shifts each total together and the ranking order stays the same. I'd still run your own number, whether that is 5 lots a month or 50, because the figure you want for budgeting is the estimated spread and commission cost at your actual trading size.

How the costs are calculated

Monthly cost = (average spread in pips x pip value at the volume entered) + (round-turn commission per lot x lots). Each ranked spread is an eight-pair average, and each row names its source window: the 5 to 9 October 2026, September 2026 and May to June 2026 figures (5 to 9 October 2026: full trading week capture, CFB SpreadLogger 1.1.0, London VPS servers; September 2026: 48-hour capture, CFB SpreadLogger 1.1.0, London VPS; May to June 2026: rolling 24-hour captures, IceFX SpreadMonitor, London VPS) come from our own captures, while a row labelled published carries the broker's own figure instead. The July 2026 row, OANDA's raw account, comes from a capture that entered our dataset on 15 July 2026 from a monthly spreads sheet rather than either of those captures, and its eight-pair basket uses USD/CAD in place of USD/CHF. 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, and I would read it before you rely on a single row of the table for a funding decision.

Pip value uses EUR/USD as the proxy for the eight-pair average, a basket quoted in several currencies rather than US dollars alone. One proxy pip value therefore gives an approximate money conversion rather than a costing of your exact pair mix, since the tool takes no per-pair volume split. When our records show a broker charging a different commission by platform, as with IC Markets and FP Markets, the Raw table ranks its MetaTrader figure and footnotes the other platform's pricing beneath the table rather than averaging two schedules.

What the ranking does not include

Three real costs sit outside this table, and I'd be remiss not to mention them. Overnight financing (swap) varies by broker, direction and holding period, and matters only for positions you hold past rollover. Currency-conversion fees apply when funding an AUD account from elsewhere or trading products settled in other currencies, so the true cost of entry can shift before a single trade is placed. 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, and it matters: slippage on a fast market can cost more than the spread itself, and I'd call that the hidden cost that catches traders out. Our lowest spread broker guide compares dated spreads, commissions and all-in pricing across brokers, and that pricing focus means it does not establish faster fills or less slippage for your trading.

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$14.33 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. Whether Raw works out cheaper depends on its spread saving per lot relative to the commission charged, so higher volume alone does not create the advantage. I'd compare both views at your own volume before picking an account style. The lowest commission broker guide covers the commission side of that trade-off, and the overall picks across all costs are in the best forex brokers in Australia guide.
