# Free tools for perpetual futures traders

Three tools with no sign-in. Everything is worked out in your browser from the numbers you type, except the funding table, which reads BloFin's public market data.

- [Position size calculator](/tools/position-size-calculator): how big a position loses exactly what you decided to risk at your stop, with fees counted.
- [Liquidation price calculator](/tools/liquidation-price-calculator): where a long or short gets liquidated, on linear and inverse contracts, at any leverage.
- [Funding rates](/tools/funding-rates): the current rate on every BloFin USDT perpetual, what it costs per day, and which side pays.

Crypto and leveraged trading can lose all of your money. These are calculations, not advice.
