A full toolkit for derivatives & spot trading
ContractCalc covers the main calculation scenarios in futures and spot trading: from basic long/short PnL to liquidation estimates, margin and leverage management, position sizing, fee and funding accounting, plus options, arbitrage and yield tools as they roll out.
Copy and formulas keep an “estimate + assumptions” stance with risk notes on every tool page, so you understand the rules behind the numbers rather than being told what to do.

Are these calculators free?
Yes, completely free and without registration. All calculations run locally in your browser.
Why do results differ from my exchange?
Most tools estimate using common contract formulas. Exchanges differ in fee tiers, maintenance margin, funding rates and liquidation rules; each page states its assumptions and disclaimers.
Which languages are supported?
Chinese and English. Chinese is the default; every page has an English counterpart under the /en/ prefix. The two versions are linked with hreflang and are indexable by search engines.
Are all tools released at once?
No. Tools launch in batches, prioritizing accurate core calculators (such as the futures PnL calculator) that offer independent content value.
Can the parameters be executed automatically?
Work out the parameters and risk limits here first, then hand the same rules to a quant system such as CubeQuants so you don't have to place orders or watch the screen manually. Fills still depend on your exchange, so validate the flow with a small size first.
