Phone Addiction Calculator
How much of your life and money goes to your phone? Get the days consumed, the share of your waking day, your checking frequency, and the opportunity cost at your state's live median wage.
At the US-average 4.5 hours/day you'll spend about 7.5 years on your phone over a 40-year adult life — 28.1% of every waking day, worth roughly $37,958/year in time.

What your phone habit is really costing you
The attention economy
Every app on your phone employs teams of engineers and psychologists to maximise your time on it — your attention is the product sold to advertisers. Naming that makes usage more intentional.
Checking fragments focus
It's not only the hours — it's the frequency. Checking 86× a day fragments attention in a way that the same hours in one deliberate block doesn't. The calculator surfaces pickups for exactly this reason.
Identity beats willpower
Research shows 'I'm not a heavy phone user' (identity framing) changes behaviour more reliably than 'I'm trying to use my phone less' (willpower framing). Tie the change to who you are.
How the phone time calculation works
Formula
Yearly Hours = Daily Hours × 365
Days/Year = Yearly Hours ÷ 24
Waking Share = Daily Hours ÷ 16 waking hours
Opportunity Cost = Daily Hours × 365 × Median Wage
Pickups/Year = Pickups/Day × 365
Min per Pickup = (Daily Hours × 60) ÷ Pickups/Day
Lifetime Days = Daily Hours × 365 × Years ÷ 24
Worked example — 4.5 hrs/day, 86 pickups, live $23/hr, 10 years:
Opportunity cost = $37,958/yr · 68 days/yr · 28.1% of waking day
Pickups = 31,390/yr · one every 3.1 minThis calculator values the time rather than just totalling hours. Opportunity cost = daily hours × 365 × your state's live BLS median wage ($23/hr nationally, May 2024), so the dollar figure reflects where you actually live; enter your own rate to make it exact.
It also tracks two things hours-only tools miss: the share of your 16-hour waking day the phone consumes (28.1% at the US average), and your checking frequency — 86 pickups/day is roughly 31,390 interruptions a year, about one every 3.1 minutes. Checking frequency is the strongest correlate of fragmented attention.
