It depends on pool size, how many degrees you want to raise the water, and your heater type. A typical 15,000-gallon pool heated about 10°F costs roughly $20–$30 in natural gas, or a few dollars in electricity with a heat pump — because a heat pump moves about five times more heat than the electricity it consumes.
