On clothes dryers that predate circuit boards I think this was a pretty
straightforward calculation, a function of the cycle time. If you know the
wattage of the heating element + the much smaller motor draw and multiply
this by the cycle time you'd get pretty close.
According to the test in the link below a typical cycle might correspond to
~2 kWh.

This paper tests (the electricity consumption of) conventional and
condensing clothes dryers:

Those exist in a number of different configurations, from the mundane P3
Kill-a-Watt for now <$20 to the much more elaborate & expensive gadgets,
some of which hook onto your breaker panel or kWh meter on the side of your
house.
