To calculate toaster efficiency, divide the useful energy absorbed by the bread (or useful heat delivered) by the electrical energy consumed: η = E_useful / E_input. Practically, measure E_input = P·t (power × time) and E_useful ≈ m c ΔT (plus energy to evaporate moisture or drive chemical changes if significant), then compute the ratio.
