We present an amplitude-generating formula in renormalizable quantum field theory. It reflects the self-similarity of loop amplitudes, in which an amplitude can also be a subamplitude of another. Amplitudes are generated by a small number of "irreducible" ones, which may replace tree-level couplings to form more complex amplitudes.
