Free perp DEX calculators using each venue's real rules

Free calculators for crypto perp traders: liquidation price, position size, leverage, funding, PnL, fees. Built on each DEX's own rules: margin tiers, funding intervals, fee tiers. No sign-up, no ads. Disclosure: the site earns exchange referral fees.
Hi Product Hunt! Most futures calculators are built around one exchange's rules: a single maintenance-margin rate and funding every 8 hours. Perp DEXs don't work that way. Hyperliquid sets maintenance margin per market (half the initial margin at the market's max leverage), with tiers by position size. Funding is paid every hour on Hyperliquid and Lighter, every 1, 4 or 8 hours on Aster depending on the market, and every 4 hours on edgeX. Each venue also has its own fee tiers and discounts. Plug DEX numbers into a generic calculator and the liquidation price and costs come out wrong, so I built calculators that use each venue's own rules.
What's in it (11 calculators in English, with Japanese and Korean versions of the main ones):
• Liquidation price on Hyperliquid, Lighter, Aster, edgeX and dYdX side by side, isolated or cross, with a stop-loss check
• A Hyperliquid calculator for one position, end to end: margin, liquidation, fees by tier, hourly funding, net PnL and ROE, for every Hyperliquid perp
• Position size from your risk and stop with fees included, plus leverage, average down, futures PnL and risk:reward
• Funding on each venue's own interval and cap, and a month of fees + funding on 4 DEXs next to Binance and Bybit
• A Hyperliquid builder-fee checker: paste an address to see which apps can add a builder fee to its orders (it reads Hyperliquid's public API)
How the numbers stay honest: every fee, tier, leverage cap and funding rule lives in one registry with its source and the date it was last checked, and the pages render from it. Each calculator writes out its formula below the form. No sign-up, no ads, and the maths runs in your browser.
Disclosure: the site earns referral commissions when people sign up to Hyperliquid, Lighter, Aster or edgeX through its links, and the tool pages carry those links, marked as such. The results don't depend on them. The calculators show standard rates by default, and the saving with the HOLYGRAIL referral code is shown separately, on its own line next to the result.
Feedback I'd love: a number that doesn't match what your exchange shows, the next venue or calculator to add, and whether the inputs make sense if you don't trade perps every day.
