Forex Trading Calculators
Five calculators that share one data spine: the spread figures come from our own May to June 2026 8-pair measurement, exchange rates refresh daily and are dated on every result, and the leverage maths applies ASIC's retail caps rather than an offshore default.
Our reviews are reader-supported. We may receive payment when you click a link to a partner site. Learn how we make money.
-
Broker cost calculator
Ranks all 29 ASIC-regulated brokers we test by monthly spread and commission cost at your trading volume, using our May to June 2026 8-pair spread measurement rather than advertised figures.
-
Position size calculator
Converts your account balance, risk percentage and stop-loss distance into a position size in lots, rounded down to the 0.01-lot step brokers accept.
-
Pip value calculator
Shows what one pip is worth in Australian dollars (or USD, GBP, EUR, NZD) for any pair and position size, including the 0.01 pip on JPY-quoted pairs.
-
Margin calculator
Applies ASIC's retail leverage caps automatically, from 30:1 on major pairs to 2:1 on crypto, and shows both the initial margin and the 50% close-out level.
-
Profit and loss calculator
Turns entry and exit prices into pips and dollars for buys and sells, so a planned target and stop become a reward-to-risk ratio before you trade.
Every figure the tools output is traceable: broker spreads and commissions render from the same dataset our best forex brokers in Australia rankings use, exchange rates carry their capture date (17 July 2026 at this build), and the margin tiers quote the ASIC Product Intervention Order directly. Where a number is missing, the tools say so instead of estimating; the capture method behind the spread data is documented on our methodology page.
