Crypto trading calculators

Start with size, not with direction

Most losing accounts are not lost on bad calls. They are lost on good calls sized badly. The position size calculator is the natural entry point: it converts a risk you can live with into an exact quantity, and it does that without leverage entering the picture at all.

From there, the liquidation price calculator tells you where the exchange takes the decision out of your hands, and the PnL calculator shows what the trade is actually worth after the round-trip fee.

Then find out whether the plan survives

A strategy is not just an edge — it is an edge plus a position size, and the second one decides whether you are still trading when the first pays off. The Kelly criterion gives you the growth-optimal fraction, the risk of ruin simulator shows what your chosen size does over hundreds of trades, and the drawdown calculator makes the cost of getting it wrong concrete.

Costs that accumulate quietly

Two costs do most of the invisible damage in crypto: funding on perpetuals and impermanent loss in liquidity pools. Both look negligible per interval and both compound into the dominant term over weeks. The funding calculator and the impermanent loss calculator put real numbers on them.
