Methodology — how we source & update fees

FeeEdge compares trading fees across 20 major crypto exchanges. Accuracy is the whole point, so here's exactly where our numbers come from and how often they're refreshed.

What we track

For each exchange we track the entry-tier (regular / VIP-0) maker and taker fee for both perpetual futures and spot. The calculator then adjusts these for your 30-day volume tier, your maker/taker mix, native-token discounts, and — on perps — an estimate of funding costs. Every figure on the site is an estimate to help you compare, not financial advice; always confirm the exact rate on the exchange before trading.

Where the rates come from

Each exchange/market uses the most reliable source available, in this order:

Live exchange API. Where an exchange exposes a clean public fee endpoint, we pull it automatically. Kraken's spot and futures fees are fetched this way.
Automated scraping. For venues without a usable API, we scrape their published fee page through Bright Data's infrastructure, with a verified per-exchange parser and strict sanity checks (a value that can't be confidently parsed is rejected rather than shown). BingX futures is sourced this way today, and we add venues as reliable parsers are verified.
Hand-verified rates. For the rest, we use published rates that we verify by hand and re-check on a recurring schedule. These carry the date we last confirmed them.

How often it updates

An automated job refreshes every exchange daily. Live-API and scraped venues update from their real source on each run; hand-verified venues are re-confirmed on a recurring monthly review, and their displayed date reflects the last verification. Each row in the calculator shows an "Updated" date and time so you can always see how current a given rate is.

What we don't capture perfectly

Funding rates (on perps) are estimated from your average hold time and live rates for major venues; smaller venues use a conservative default. Withdrawal fees, spreads and slippage are real costs that vary constantly — we surface withdrawal and spread context but they can't be pinned to a single number. When in doubt, the exchange's own fee page is the source of truth.
