The True Yearly Cost of a Small Daily Habit

Small daily purchases feel harmless because each one is small. Multiplying them out, and asking what the money could do instead, can change how they look.

The yearly cost

A $5 coffee on five workdays a week: 5 × 5 × 52 = $1,300 a year. Every day of the year, it's 5 × 365 = $1,825.

Other examples:

• A $12 lunch out, 3 times a week: $1,872 a year
• A $15-a-month subscription you don't use: $180 a year
• An $8 snack run twice a week: $832 a year

The opportunity cost

Money not spent can be saved or invested. If you put $1,300 aside at the end of each year and it earned 5% a year, compounding, after 10 years you'd have about $16,350, of which around $3,350 is growth.

Returns aren't guaranteed and investments can lose value, but the example shows how small amounts add up over time.

Turn it into a goal

Instead of cutting a habit completely, decide what it's worth to you. You might keep the coffee but brew at home three days a week, then send the difference to a savings goal. Knowing the target and the date you want it by tells you how much to put aside each month:

Interest earned along the way only helps.

Beyond money

The same method works for time. Twenty minutes a day of scrolling is more than 120 hours a year, about three full working weeks.
