And if that amount seems high, you're also in good company. Four out of 10 people surveyed said they get even less free time than that total, incredibly.

The survey of 2,000 adults, commissioned by tax prep service H&R Block, also found that the little bit of free time leaves the average person with 14 undone items on their to-do lists — though one in five respondents says there's at least 20 things to get done on their lists. Those lists include everything from running errands to paying the bills. The authors found that 60% of the participants are putting off basic administrative tasks like cleaning, going to the bank, or filing their taxes because they don't have the time.

Nearly the same amount, 59% of participants, said keeping their lives organized with everything they have going on is simply a "big struggle."

Among the tasks most commonly brushed aside by the study participants, cleaning topped the list, with 48% of adults postponing such chores. Another 40% admit they've put the brakes on car maintenance, while a third routinely push back plans to go shopping. More than a quarter of Americans (27%) said they put off making a doctor's appointment.
