To copy from the tezos.git docs:

fees >= (minimal_fees + minimal_nanotez_per_byte * size
                      + minimal_nanotez_per_gas_unit * gas)

(size is the size of the operation in binary.)

With current defaults:

minimal_fees = 0.000 1 ꜩ (100 µꜩ)
minimal_nanotez_per_gas_unit = 100 nꜩ/gu (0.000 000 1 ꜩ/gu)
minimal_nanotez_per_byte = 1000 nꜩ/B (0.000 001 ꜩ/B)
