XRP Fee Levels
Fee levels represent proportional differences between the minimum cost and the actual cost. Open ledger cost is measured in fee levels rather than absolute drops. Reference transactions have a minimum of 256 fee levels and double cost is 512 fee levels.
Open ledger cost is a second threshold. A transaction can only be included in the current open ledger if it meets the open ledger cost requirement. After a soft limit is reached, the open ledger cost can increase rapidly, and transactions may be queued for later ledgers.
Some transactions have special costs before load scaling: most reference transactions cost 10 drops; multi-signed transactions cost 10 drops × (1 + number of signatures); EscrowFinish with fulfillment costs 10 drops × (33 + (fulfillment bytes ÷ 16)); AccountDelete and AMMCreate cost 2,000,000 drops; a key reset SetRegularKey can be 0 under specific conditions.
FAQ
Is the Fee field changeable after signing?
No. Like other signed fields, changing Fee invalidates the signature.
Can I overpay fees?
Yes. The ledger destroys exactly what you sign, even if it is higher than the minimum.
