Leverage Calculator: Effective Leverage Tool
Effective leverage is not the maximum your broker permits but the ratio you are actually running: position value divided by margin.

Risk warning. Leveraged forex trading carries high risk and, in Türkiye, is subject to SPK regulation (1:10 leverage cap, ~50,000 TRY margin). This content is not investment advice; user statements belong to their authors.
Permitted leverage is not the leverage you use
Your account may allow 1:10, but if you carry a small position your effective leverage is 1:2. What drives risk is the ratio actually in use, not the ceiling.
The distinction matters because effective leverage adds up across positions on the same account. Trades that look reasonable individually can strain margin together.
The legal cap in Türkiye
The SPK's investor booklet is explicit: in leveraged trading the leverage ratio is applied at a maximum of 10:1. For customers whose initial margin at account opening is below TRY 50,000 or its foreign-currency equivalent, at most half of that — 1:5 — may apply.
Platforms advertising ratios such as 1:500 are sites not authorised by the SPK. Detail is in our 1:10 leverage cap article; you can verify authorisation on the SPK-licensed companies list.
What changes as leverage rises
The margin required falls, but so does the price move needed to close the position out. Carrying a larger position on the same capital directly raises the chance of a margin call.
You can see the margin a position requires with the margin calculator, and an appropriate size with the lot calculator.
