BitcoinMargin's tools page collects every free crypto calculator and trading utility we publish — built for active derivatives traders, long-term DCA investors, and anyone who wants concrete numbers instead of generic guides. Each tool runs entirely in your browser, asks no sign-up, stores no inputs, and ships with a written explanation so the math is reproducible rather than opaque.
The liquidation calculator estimates the price at which a leveraged long or short gets force-closed on Binance, Bybit, and Kraken Futures, accounting for maintenance margin, funding, and cross-vs-isolated mode. The position-size calculator inverts the question — given the maximum dollar loss you accept on a single trade, what notional and leverage match it? The profit calculator handles fees, funding accrual, and entry/exit slippage so the P&L number reflects what you actually keep. The DCA calculator backtests dollar-cost-averaging against any spot pair using historical price data; you set the cadence, amount, and window and see the realised cost basis next to a lump-sum baseline.
Alongside the calculators are live data dashboards — open interest, funding rates, liquidation heatmaps, market-cap rankings — refreshed on a short cadence and sourced from the same exchanges you trade on. Nothing here is a paywalled signal service; everything is methodology you can verify line-by-line.
