What it costs to move $20 on eight networks

Moving $20 across eight networks cost between under a cent and ten dollars in FeeEdge’s survey of 17 August 2026. As a share of the amount moved, that is 0.01% to 50%. At the top of the range the fee is not a cost attached to the transfer. It is the transfer.

A flat fee against a small ticket

Network fees price computation and block space, not value. A $20 transfer and a $20,000 transfer consume roughly the same resources, so they cost roughly the same. The absolute fee is flat and the percentage is not.

That makes the percentage the only honest way to read a fee on a small ticket. Halve the amount and the percentage doubles. The same $5 fee is 25% of $20, 0.5% of $1,000, and 0.05% of $10,000.

Most fee comparisons quote the absolute number, because absolute numbers are easy to publish and they flatter the expensive chains. A fee table in dollars answers a question nobody with a small balance is asking.

Eight networks, one twenty-dollar bill

The range in the survey is wide enough to change behaviour. Solana came in under $0.01, which is under 0.05% of $20. Polygon PoS was $0.002 to $0.01. BNB Chain was $0.01 to $0.20. Base was under $0.01 to $0.10. Arbitrum was $0.01 to $0.50.

Then the range breaks. Tron was $1 to $3, or 5% to 15% of the transfer. Bitcoin was $0.50 to $5 or more. Ethereum L1 ERC-20 was $2 to $10, with congestion taking it above $50, which is 10% to 50% of a $20 move and more than 250% in the worst case.

A $50 fee on a $20 transfer costs two and a half times the amount being moved. The transaction still validates and still confirms. It is simply irrational, and no yield on the board repairs it.

The recovery arithmetic

A fee is a loss you have to earn back before the position is whole. The required gain is not the fee percentage. It is the fee divided by what remains.

Pay 10% and you hold $18 of a $20 position, so you need 11.1% to get back to $20. Pay 15% and you need 17.6%. Pay 25% and you need 33.3%. Pay 50% and you need 100%.

Set that against the yields on the board. ETH staking paid 2.63% gross in Q3 2026. Tokenised T-bills paid 3.60% to 3.61% annualised on 7 October 2026. A 10% transfer fee is nearly four years of gross staking yield. The 15% that Tron’s high end produces on a $20 move is more than five years of it.

That is the comparison that makes a fee decision, and it has nothing to do with which chain is faster.

The withdrawal fee is the bigger one

The network fee is not the only charge on a small transfer. The venue charges too, and on small tickets that charge dominates.

FeeEdge’s 17 August 2026 figures put exchange withdrawal fees at about 0.5 to 1 USDT for Solana SPL, roughly 0.3 USDT for BEP-20, and highest for ERC-20. On a $20 withdrawal, 0.5 to 1 USDT is 2.5% to 5% before the network fee is counted at all.

Entry-tier spot taker fees sat near 0.10% in the same survey, which is about $0.02 on a $20 trade. Trading is the cheap part. Leaving is the expensive part, and the published fee page usually lists both without ranking them.

What to do next

Batch. The fee is per transfer, so consolidating five $20 moves into one $100 move cuts the fee bill by four fifths and cuts the percentage by the same factor.

Choose the rail by ticket size rather than by habit. Under a few hundred dollars, Solana and Polygon PoS hold the fee below 0.05% of the amount, and Ethereum L1 holds it at 10% or worse. Above a few thousand, the L1 absolute cost stops mattering and its depth starts to.

Then check the page before sending. Fees are published per venue and they change, and the numbers above are one survey on one date. Our fee page tracker exists because a fee quoted in a guide is a fee that has already moved. Compare venues on the exchange board using the withdrawal column rather than the trading column, since the withdrawal column is what a small balance actually pays.
