What does the work lunch cost from age 30 to 65?
The Work Lunch
$12 a day, five days a week, age 30 to 65 — the long-term cost is $426,000.
How the number's built.
Buying lunch is convenient and social. A natural break in the working day. But an extra $12 spent daily becomes $2,880 a year. Compounded at 7% over 35 years, it reaches $426,000. Not because eating is wrong. Because the baseline adjusted to convenience without a vote.
Bringing lunch three days a week, not zero.
$256,000 stays compounding.
No rush. It keeps until you want it.
