Live mark prices · calculator only
See where a leveraged trade breaks, before you place it.
Pick a market, set your money and your leverage, and Perpkiln shows the price that would wipe you out, what holding costs per hour, and your profit or loss at any price.
Uses live perpetual-futures prices and funding from a public exchange feed. Perpkiln never places a trade and never touches funds.
How it works, in 3 steps
Tell it your trade
Market, long or short, your money and leverage.
It reads live prices
Mark price and funding from a public perps feed.
You see the danger line
Wipe-out price, hourly cost and profit curve.
No trade is placed, nothing is charged, and you never need to sign.
Liquidation calculator
What this does: it finds the price at which a leveraged position would be closed by the exchange and your margin lost, called the liquidation price.

- In coins

- Room before wipe-out

- Maintenance cushion

- Trading fees, open + close

Model of the exchange's published isolated-margin rule (maintenance = half of initial margin at max leverage). Real fills, tiers and fees can differ.
Funding: what holding costs per hour
What this does: it shows the live hourly funding rate and the last 7 days of it, then works out what your position would pay or earn over the time you hold it.
Uses the market and size from Sheet 1. Press Read funding.
- Now, per hour
- -
- 7-day average, per hour
- -
- As a yearly rate
- -
- Your cost for the hold

Profit curve and a 7-day replay
What this does: it draws your profit or loss at every price, then replays the same trade on the real last 7 days of hourly prices to show whether it would have survived.
Press Draw my curve.
Press Replay the last 7 days.
Glaze tiles: the busiest markets, live
What this does: it lists the most traded perpetual markets right now. The warmer the tile, the more expensive funding is. Click a tile to load it into the calculator.
Safe leverage finder
What this does: it scans the last 30 days of hourly prices for the worst move against you within a holding window, and finds the highest leverage that would have survived it. A model of the past, not a guarantee.
Uses the market and direction from Sheet 1.
Any Solana token, as a model
What this does: most Solana coins have no perp market, so this applies the same maths to any token's live Jupiter price with a funding rate you choose. The funding is a model, not a market rate.
Pick a token to see its wipe-out price.
A firing, step by step
How leverage heats a trade until it cracks
- Load the kiln. You put up margin: the money you can lose.
- Raise the heat. Leverage multiplies it into a bigger position.
- Time costs fuel. Funding is paid or earned every hour you hold.
- The crack line. If price reaches the wipe-out line, the margin is gone.

Perpkiln coin: the planned structure
This is planned: no coin exists yet. The coin would not unlock features or pay anyone; the tools here stay free.
Fair launch: anyone buys on the same curve; mint and freeze authority switched off. Nothing here is a promise of price or return.
The trading words, in plain terms
Perpetual future (perp): a bet on a coin's price with no end date, usually with leverage.
Long / short: long wins when price rises, short wins when it falls.
Mark price: the fair price the exchange uses to judge your position.
Margin: the money you put up and can lose.
Leverage: position size divided by margin.
Liquidation: the exchange closes you out when margin runs out.
Funding: hourly payments between longs and shorts.
Wallet connect: lets the page read your address and balance; it can't move funds.
Questions from the studio floor
What is this, in one sentence?
A calculator that shows where a leveraged crypto trade would be wiped out, what it costs to hold, and how it would have fared over the last week, using live prices.
Is it safe? Does it touch my money?
No money is involved. Perpkiln places no orders and holds nothing. If you connect a wallet it only reads your public address and balances so it can fill in your margin; there is nothing to sign.
Is the liquidation price exact?
It follows the exchange's published isolated-margin formula with its first margin tier, so it is close for ordinary sizes. Very large positions, cross margin and fees can move the real number.
Where does the data come from?
Mark prices, funding and hourly candles come from Hyperliquid's public info API. Solana token prices come from Jupiter. Wallet balances come from Solana mainnet through this site's read-only connection.
Can I trade from here?
No. This is a planning tool. Leveraged trading can lose all of your margin quickly; nothing here is advice.
Plain disclosure
Live: mark prices, funding, candles, Jupiter prices and wallet balances. Model: liquidation, fees, safe leverage and any Solana-token funding. Perpkiln never holds funds, never sends orders, and has no partners, audits or user counts to claim.
