Fees, funding & notional
Trading fees and funding are usually calculated from exposure under the contract's rules, not simply from the margin you deposit.
The guide works through the definitions, the arithmetic, and the practical checks. Read the assumptions alongside the example, then use your own inputs in the calculator to see what changes.

Understand perpetual futures fees, funding, and execution costs before comparing a trade's potential outcomes.
Start with the guide for context, use the calculator to work through a scenario, and check the comparison framework before evaluating a product.
- Trading fees
- Calculate entry and exit fees separately using the relevant notional.
- Funding
- Check the rate, direction, interval, and product-specific payment rules.
- Notional
- Separate position exposure from margin and leverage.
- Execution
- Include spread and slippage when comparing the full cost of a position.
Evidence before a verdict
A useful comparison makes its assumptions visible.
Our starting library focuses on explainers and transparent calculations. Example amounts illustrate a method. They are not current market prices, verified provider fees, or measured product performance. Where a detail depends on a service, follow the linked primary documentation and confirm the terms that apply to your account and region.
Reviews should say whether a product was tested, which version or date was examined, and which findings came from documentation. A calculator output does not replace that evidence. We do not publish invented ratings, user counts, or profit claims.
