Crypto Trading Calculators
Eight free calculators for the numbers you should know before you click buy. They work for any exchange, not just Hyperliquid, and nothing here asks you to sign up or connect a wallet. Everything runs in your browser.
Nothing you type here is sent anywhere. The arithmetic runs in the page, which is why these work offline, why there is no sign-up, and why we could not sell your inputs even if we wanted to.
Position Size Calculator
Work out exactly how big a position to open from your account size, risk percentage and stop-loss distance. Free, instant, no sign-up.

Why the numbers before a trade matter more than the ones after
Most traders compute carefully after the fact. They know their PnL to the cent, they can tell you exactly where a trade went wrong, and they have a detailed post-mortem for a position that was sized wrong from the moment it opened. The arithmetic that actually determines whether an account survives happens in the thirty seconds before you click buy, and almost nobody does it.
That is the entire reason these calculators exist. Not because the maths is hard: most of it is one line of algebra. Because doing it in your head, quickly, while a price is moving and you feel like you are missing something, reliably produces the wrong answer. A calculator removes the part of the decision that your judgment is worst at, and leaves you with the part it is actually good at.
How the eight calculators fit together
They are not eight versions of the same thing. Each answers a different question, and they slot into roughly the order you would ask those questions in.
| Stage | Question | Tool |
|---|---|---|
| Before entry | How big should this position be, given what I am willing to lose? | Position size |
| Before entry | Is this trade worth taking at all? | Risk / reward |
| Setting up | How much margin does this require, and what leverage does that imply? | Leverage |
| Setting up | Where does this position get closed against my will? | Liquidation price |
| Setting up | What price do I need just to get my money back after fees? | Break-even |
| While held | What is this position costing me per hour to keep open? | Funding rate |
| While held | If I add here, where does my average entry end up? | Average down |
| Any time | What is this worth at a given target price? | Profit and loss |
Position sizing is the one that changes outcomes
If you only ever use one of these, use the position size calculator. Leverage gets all the attention, but leverage is downstream of sizing: it is just the ratio that falls out once you have decided how much notional exposure to take against how much margin. Sizing is the decision itself.
The logic is simple enough to state in a sentence. Decide the maximum you are willing to lose on a single trade, usually a small percentage of the account. Decide where the trade is wrong, which is where your stop goes. The distance between entry and stop, divided into your risk budget, gives the position size. Everything else follows.
position size = risk amount ÷ (entry price − stop price)
risk amount = account equity × risk % per tradeWhat makes this powerful is that it inverts the usual thinking. Instead of picking a size and discovering what you might lose, you fix what you might lose and derive the size. A wider stop automatically produces a smaller position, so a low-conviction setup with a distant invalidation level cannot quietly turn into your largest trade.
What these calculators assume, and where reality differs
Every calculator is a model, and being explicit about what a model leaves out is more useful than pretending it leaves out nothing.
- Fills happen at the price you type. In practice, market orders on thin books fill worse than the quoted price. That slippage widens your real entry, shifts break-even, and pulls liquidation slightly closer.
- Fees appear only where relevant. Break-even includes them because that is the whole point of the tool. Most of the others show clean arithmetic so the mechanism is visible, which means real results land marginally worse than the output.
- Funding is a separate line item. A position held for days can pay more in funding than it pays in trading fees. Hyperliquid charges funding hourly, which is eight times more frequent than most centralised venues, so headline rates are not directly comparable across exchanges.
- Maintenance margin varies by venue and by asset. Leave it at zero and you get the textbook liquidation level. Real liquidation sits slightly earlier, because the exchange holds back a maintenance requirement rather than letting equity reach zero.
- Cross margin changes the answer. These calculators treat a position in isolation. Under cross margin your whole balance backs every position, so an unrelated losing trade drags this one closer to liquidation.
From typed numbers to real ones
Calculators work on hypotheticals. At some point the more useful question is what your actual trading has done, and that is a different exercise: not what a position might return, but what your realised win rate, average hold time, fee burn and worst drawdown actually are across every trade you have ever made.
That is what the main LabelYX dashboard does. Paste a public Hyperliquid address and every metric above is computed from real fills rather than assumptions, with no sign-up and no wallet connection. If you are still building the underlying intuition, the Learn library covers the concepts these tools operate on, from leverage and margin to how liquidation actually works and risk management and position sizing.
Trading calculator FAQ
Do these only work for Hyperliquid?
No. Each calculator applies standard perpetual futures arithmetic to the numbers you type, so they work equally well for Binance, Bybit, OKX, dYdX or any other venue. The one venue-specific input is maintenance margin, which differs by exchange and by asset, and can be entered manually where it changes the result.
Do I need an account, and is my data stored?
No account, no email, no wallet connection. Each calculator is client-side arithmetic that runs entirely in your browser, so the numbers you type are never sent to a server and never stored.
Which one should I start with?
The position size calculator. It answers the only question that reliably changes long-run outcomes: given what you are willing to lose and where the trade is invalidated, how large should the position be? Risk/reward and liquidation price are the natural next two.
Why does my exchange show a different liquidation price?
Almost always maintenance margin. Run with maintenance at zero, a calculator returns the simple textbook level, while the exchange liquidates slightly earlier because it holds back a maintenance requirement. Cross margin changes it again, since your full balance backs the position, and unrealised PnL on other open positions moves it continuously.
Do they include fees, funding and slippage?
Only where the tool says so. Break-even includes fees by design, and the funding rate calculator prices the carry on a held position. The rest show clean arithmetic so the mechanism stays visible, which means live results land slightly worse once fees, funding and slippage are applied.
Can I get these numbers for a position I already hold?
Yes. Paste a public Hyperliquid wallet address into LabelYX and the same metrics are computed from that account's real trade history rather than typed inputs: realised PnL, win rate, fees paid, funding paid, open positions and drawdown. Still free, still no sign-up.
