Calculators
Calculators & tools
Work out costs and risks before you trade, not after.
These calculators are decision aids, not advice. They make visible what a year of trading, a savings plan or a leveraged position actually costs — with your numbers, not a worked example. Every formula is stated on its page and every assumption sits under the result. What you do with that is your call.

Arithmetic is not advice
Every result follows from your inputs and the assumptions we disclose. Taxes, spreads, slippage and individually negotiated terms are not modelled unless stated. Always check critical figures against your broker's own pricing schedule.
