Free Crypto Trading Tools
Professional-grade cryptocurrency calculators and market tools — completely free, no sign-up required. Built for traders who need fast, accurate calculations for risk management, position sizing, and market analysis.
Every calculator on this site is open about its math. The Liquidation Calculator uses the same maintenance-margin formula Binance and Bybit publish in their API docs. The Position Size Calculator implements the percent-risk model that risk managers at proprietary trading desks use. There is no proprietary algorithm hiding behind a paywall — the inputs you enter and the formulas applied are the same ones a senior trader would calculate by hand.
Margin & Derivatives
Calculate your liquidation price before opening a leveraged position. Our Liquidation Calculator supports isolated and cross margin modes for Binance, Bybit, and other major exchanges. The Position Size Calculator helps you determine the optimal trade size based on your risk tolerance, and the Risk/Reward Calculator visualises your potential outcomes before you commit capital.
These four tools cover the questions that get traders stopped out: 'Where will my position liquidate?', 'How big can my position be without risking more than 2% of account?', 'Is this trade worth taking given the reward versus the stop distance?', and 'What will the maker/taker fees cost across the round trip?'. Run them in order before every position. The five minutes spent on inputs prevents the kind of forced exit that turns a winning week into a losing month.
Market & Sentiment
Monitor market sentiment with the Crypto Fear & Greed Index, track funding rates across exchanges, analyse open interest and derivatives volume, explore the order book depth for crypto derivatives, and follow the Bitcoin Halving Countdown. These tools help you understand the broader market context before making trading decisions.
Sentiment data is most useful when it disagrees with price. The Fear & Greed Index reading 'Extreme Greed' during a parabolic rally is a contrarian signal — historically the worst time to add leverage. Funding rates persistently above +0.05% per 8h indicate crowded longs paying to hold their positions, often preceding a deleveraging cascade. Open interest growing while price stalls hints at building tension. Read these together rather than in isolation.
Converters & Calculators
Convert between cryptocurrencies and fiat currencies in real time with our Crypto Converter and Forex Converter. Simulate long-term investment returns with the DCA Calculator and Compound Interest Calculator. Plan for purchasing power erosion with the Inflation Adjuster. All tools support multiple currencies including USD, EUR, GBP, and more.
The DCA Calculator answers a question almost nobody runs the numbers on: 'How would my returns compare if I had bought $100 of Bitcoin every week starting in 2017 versus a single $X lump sum on the same day?'. The Compound Interest Calculator shows how staking yields and reinvested returns differ from simple interest over multi-year horizons. Inputs default to realistic values — 4-12% annual yields rather than the 60-100% APY screenshots that appear in promotional material — so the projections reflect what disciplined investors actually achieve.
How to Choose the Right Tool
Pick the tool by the question you are trying to answer, not by the calculator's name. Before opening a leveraged trade, the order is: Position Size Calculator (how much can I risk?) → Liquidation Calculator (where is the floor?) → Risk/Reward Calculator (is the trade worth it given the stop distance?) → Fee Calculator (what does round-trip cost?). For long-term decisions, the order is: DCA Calculator (would dollar-cost-averaging have outperformed a lump sum on my asset?) → Compound Interest Calculator (what does a 5-year horizon look like?) → Inflation Adjuster (what is the real return after purchasing-power decay?).
Calculators are pre-trade tools. They help you size, plan, and stress-test a position before capital is at risk. They do not replace the live monitoring that funding rates, open interest, and the Fear & Greed Index provide once a position is open — those market-sentiment dashboards are post-entry tools that flag when the conditions you opened the trade under have changed.
Common Mistakes These Tools Prevent
The most common avoidable losses traders take are: (1) opening positions sized to a notional dollar amount rather than a fixed percentage of account — fine on a winning streak, devastating during drawdown; (2) calculating a liquidation price by eyeballing leverage instead of running the maintenance-margin formula, which understates the true liquidation distance by 5-15% on isolated-margin positions; (3) ignoring the funding-rate cost on positions held longer than 24 hours, which can erode 2-5% per week on crowded perpetuals; (4) skipping the fee math on small-edge trades where round-trip taker fees consume the projected profit.
Each of these is a one-input fix. The Position Size Calculator forces a percent-risk number rather than a dollar amount. The Liquidation Calculator uses the actual exchange formula. The Funding Rates dashboard surfaces the holding cost before you open the trade. The Fee Calculator shows the breakeven move required to clear maker/taker plus slippage. Five minutes of pre-trade math eliminates the most expensive class of errors.
Tool Accuracy & Data Sources
Live price data comes from Binance's public WebSocket and REST APIs, refreshed every 1-3 seconds. Funding rates and open interest are pulled from the same source so the readings reconcile with what you see inside the Binance terminal. The Fear & Greed Index sources from Alternative.me's published methodology — a weighted blend of volatility, momentum, social-media sentiment, dominance, and search trends. Halving countdowns calculate from the genesis-block timestamp plus the actual on-chain block-height progression rather than a hardcoded date.
Where a calculator depends on exchange-specific behaviour (e.g. liquidation thresholds), the formula tracks the public documentation of that exchange. Margin requirements are checked monthly against the latest published values; the page footer notes the last verification date. If you spot a divergence between a calculator output and what your exchange shows, treat the exchange as authoritative — and email the discrepancy so the formula can be re-verified.
