How Many Decisions Do You Make in a Day? is a free online interactive calculator that estimates your daily decision load based on behavioral factors like smartphone use, work intensity, and social exposure. Researchers estimate the average person processes around 35,000 decisions daily — most happening below conscious awareness. This tool lets you explore and visualize your own estimate.
You start by guessing how many decisions you think you made today. The tool then reveals a research-based estimate and breaks it down by category — attention shifts, digital micro-actions, food choices, social communication, and more. Interactive sliders let you adjust factors like day type, commute, and parenting to see how different lifestyles change the number. A dot visualization renders every single decision on screen.
Researchers estimate the average person makes around 35,000 decisions per day, though most are automatic micro-choices processed below conscious awareness. The exact number depends on factors like smartphone use, work intensity, and social exposure.
A decision includes any micro-choice your brain processes: where to look, what to tap, how to word a sentence, whether to respond, which route to take, when to eat, and what to ignore. Most happen automatically without conscious awareness.
Yes, significantly. Smartphones, notifications, and infinite digital options have dramatically increased daily decision load. A typical day in 2025 involves roughly 60% more decisions than a pre-smartphone day circa 2005.
