IEPTO

IEPTO answers the cost and risk questions that generic trading widgets skip for three exchanges, Binance, OKX and Bybit. Each calculator uses the exchange's own published rules rather than one generic formula. The liquidation calculator compares where the same position would be liquidated on each exchange. The home page shows a 10x long in XRP whose distance to liquidation ranged from 6.5% to 8.9% depending on the exchange. The fee calculator works from your 30-day volume tier and platform-token discount. The funding arbitrage calculator estimates the return on a funding-rate spread after costs, and the position size calculator works backward from your capital, stop distance and risk.

The DCA calculator is labeled as a fixed, repeatable price path, not a backtest on real history. Funding-rate pages show the last settlement time for each exchange, and guides cover exchange sign-up, verification and futures account setup. The site is in English, Traditional Chinese and Simplified Chinese.

The site is upfront on the points that matter. Exchange data carries its source and date, and calculator results state their assumptions. The about page says guides are checked against official exchange documents, AI tools help with drafting and translation, and anything that can only be confirmed on a real account is marked as not tested. It has no accounts and says it will never ask for exchange passwords, API keys or seed phrases. It says it does not serve users in mainland China and tells readers to check that an exchange is legal where they live.

The money comes from referral links. Some exchange links pay IEPTO a share of trading fees when you register through them. The site discloses this on every page and says it does not change calculations or table order, but the business still benefits when readers trade more. The activity itself is high risk. Leveraged perpetual futures can lose your whole stake, and the site says nothing on it is investment advice. We did not find a privacy policy page. Use it to check numbers on a decision you have already made, not as a reason to start trading futures.
