# Fees overview

Fees have 16 decimals (the precision for fees calculation). When the admin setups fee, he should add 16 extra symbols (multiply by 10^16). For example:

- 15% must be 15 * 10^16;
- 21.5% must be 21.5 * 10^16;
- 19.99% must be 19.99 * 10^16;
- 1% must be 1 * 10^16;
- 100% must be 100 * 10^16.
