The destination sets the price
Delivering to Ethereum means an Ethereum transaction, priced in ETH by whatever the network is doing at that moment. Every provider above carries that cost and passes it on, which is why quotes on this route are higher than on the way into BNB Smart Chain and why they move through the day. The quotes here carry a timestamp rather than being published as a fixed list.
What arrives is a separate token
The ERC-20 balance you end up with on Ethereum (Ethereum.org) is not the BEP-20 balance you sent from BNB Smart Chain (BNB Chain documentation) — the two chains simply hold separate records. Nothing about the transfer is reversible by the same route for free; going back is its own transfer at its own price.
Gas at both ends
Sending costs BNB; using the result costs ETH. The gas column above covers only the transaction on BNB Smart Chain, the network you are leaving. Arriving on Ethereum with no ETH means holding a balance you cannot move.
Or move it through an exchange
A deposit on BNB Smart Chain and a withdrawal on Ethereum is the other way across, with its own fee and minimum. Where we have checked the figure, that row sits beside the bridge quotes whether or not it wins.
Questions
How do I convert BEP-20 to ERC-20?
There is no conversion. BEP-20 is the token on BNB Smart Chain, ERC-20 the token on Ethereum, and they are separate balances. A bridge or an exchange moves value between them; both are priced above.
Why is this direction more expensive than the reverse?
Because the provider has to pay for a transaction on Ethereum to deliver your funds, and that cost moves with Ethereum gas. The same pair in reverse is usually cheaper.
Can I use the same address on both networks?
The same string is valid on both, which is convenient and dangerous in equal measure. What matters is the network chosen when sending; the address alone proves nothing.
What will I need on Ethereum?
ETH for any transaction you make there afterwards. The fee in the table covers delivery, not your next move.
