# RektCalc

> Free crypto trading risk calculators — liquidation price, position sizing, funding rates, DCA, and fees. No signup. All calculations run client-side in the browser; nothing is sent to a server.

RektCalc helps leveraged crypto traders understand their real risk before they trade: exact liquidation price by exchange, how much to risk per position, what funding actually costs over time, and whether a DCA plan or a trade's math actually works out after fees.
