Three reasons every other fee calculator gets this wrong.
Every "0% commission" claim hides 1–3 % in spread. Here's how we keep them honest.
Every hidden fee, exposed
Most platforms hide spread inside the price. We pull it apart line by line so you see what you really pay.

People who stopped overpaying
Real buyers. Real numbers.
"Saved $340 last quarter just by switching from Coinbase to Kraken on my weekly buys. The math is right there."
"The spread column is what every other calculator misses. That's where 70% of the real fee actually lives."
"Realized I'd been losing close to 4% per buy for a year on the 'no fee' app. Wish I'd seen this on day one."

No black box. Here's the exact math behind every number on this page — so you can verify it yourself.
True Cost =
- Trading fee — the exchange's taker fee per trade
- Spread — the gap between buy/sell price (estimated)
- Deposit fee — cost to deposit fiat to the exchange
- Withdrawal fee — cost to move crypto off the exchange
