How to Use the Annual Lunch Cost Calculator
Lunch seems like a small daily expense, but it adds up fast. At $12 per day for 250 work days, that's $3,000 per year — and $30,000 over a decade. Enter your typical daily lunch spend and work days to see your annual total. Add a meal prep cost to instantly see the savings comparison.
The average American worker spends $10–$15 per bought lunch. A home-prepped meal using grocery ingredients typically costs $2–$4. Switching even 3 days a week adds up to over $1,000 in annual savings for most people.
You don't have to go all-in to benefit. Start with just Monday and Wednesday meal prepping. That alone could save $500–$900 per year depending on your current spending. The 5-year and 10-year projections put the cumulative impact in sharp relief.

Batch cooking on Sundays can cover 3–5 lunches in about 1 hour. If your hourly rate is $20 and you save $9/day for 3 days, that's a $27 gain for roughly 36 minutes of prep — a solid return.
