Exchange interfaces and order types.

Most exchanges have two completely different fee structures depending on which interface you use. The consumer app and the pro/API interface are not the same product. Here is the full breakdown with concrete numbers.

Level 1: Consumer app / basic recurring buy

The buy button most people use. The exchange charges a flat fee that bundles everything.

• Coinbase: ~1.88% spread + 1% fee = ~2.88% total
• Kraken: 1% for instant buys, 1.5% for custom orders
• Binance: 0.40% spread for basic recurring.

Level 2: Pro interface, market order (taker fee)

This means using the exchange's pro or API interface. A market order fills instantly at the current best available price. It's called a taker fee because you take liquidity from the order book.

• Coinbase Advanced Trade base tier: 1.20%
• Kraken Pro base tier: 0.40%
• Binance Pro or API: 0.10%

Level 3: Pro interface, limit order (maker fee IF it rests)

You set the price you want. If your order rests in the orderbook waiting to fill, you add liquidity and pay the maker fee. If your limit price crosses the current spread (e.g. a buy above the current ask), the order executes immediately and you pay the taker fee, not maker. To actually get the maker rate, you have to set below the current ask and accept the risk of non-fill.

• Coinbase Advanced Trade base tier: 0.60%
• Kraken Pro base tier: 0.23%
• Binance Pro or API: 0.10% (same as taker. Binance doesn't differentiate at base level)

What $500/month actually costs

Annual volume: $6,000

That is the same $30,000 deployed over 5 years. The range goes from $30 to $864.

Where the real savings are:

Coinbase consumer app to Advanced Trade market order saves you $101 a year. That is the single biggest move anyone on Coinbase can make before touching order types at all.

Binance basic recurring to API drops the fee from 0.40% to 0.10%. Four times cheaper on the same exchange.

Coinbase Advanced Trade market to limit order cuts the fee in half from 1.20% to 0.60%. But it introduces execution risk. If you set a limit and Bitcoin moves past it, the order doesn't fill. For a consistent daily or weekly DCA schedule, that missed entry can cost more than the fee you saved.

Kraken consumer to Pro drops the market order fee from 1.00% to 0.40%. Over twice as cheap.

These are base-tier fees. Higher 30-day volume unlocks lower tiers on all three exchanges. Coinbase One subscription plans change the Coinbase math in specific volume ranges.

EDIT: clarified Level 3 — a limit order only earns the maker fee if it rests in the orderbook. Aggressive limits that cross the spread pay taker. Thanks u/gettinmerockhard for the catch.
