Understanding XRP Drops and Network Fees
An XRP drop is the smallest denomination of XRP on the XRP Ledger. One XRP equals exactly 1,000,000 drops. Drops are used internally by the XRP Ledger to calculate and specify all fees with integer math, avoiding floating-point rounding errors.
Drops to XRP Conversion
The base XRPL network fee is 10 drops, which equals 0.00001 XRP. At an XRP price of $2.50, this is $0.000025 per transaction - less than a thousandth of a cent. Even at the highest XRP price ever recorded, the drop-based fee remains effectively free for practical use.
How the Fee Field Works
Every transaction submitted to the XRP Ledger must include a Fee field specifying the fee in drops. The transaction is invalid without this field. The specified amount is burned regardless, even if it exceeds the minimum. This means if you accidentally set a very high fee, those drops are gone permanently.
Querying Current Drop Fees
You can query the current fee in drops using the XRP Ledger fee command via HTTP or WebSocket API. The response includes minimum_fee (always 10 drops under normal load), median_fee (based on recent transactions), and open_ledger_fee (the cost to be included in the current ledger immediately).
The design using drops enables the XRP Ledger to calculate fees with only integer math while allowing fine-tuning for server load. XRP Ledger Protocol Documentation
