For Cleveland workers riding out inflation, the lunch question hits close to home. While grocery prices have climbed, restaurant prices have climbed faster — 3.4% for eating out versus 2.7% at the store. That gap matters most if you're buying lunch every single workday.
Peter McHenry, an economics professor at William & Mary, argues the financial answer is actually pretty clear: if saving money is the goal, preparing the right food at home wins. The harder question is whether money is the only thing that matters.
The Lunch Cost Breakdown
| Packed Lunch | Fast Food Combo | Sit-Down + Tip | |
|---|---|---|---|
| Daily cost | $3 | $8–$14 | $18 |
| Weekly cost (5 days) | $15 | $40–$70 | $90 |
| Monthly cost (4 weeks) | $60 | $160–$280 | $360 |
| Price increase (past year) | 2.7% (groceries) | 3% (fast food) | 3.4% (eating out) |
I think it's pretty clear that if you want to save money then you can pretty clearly get food for a lower price if you prepare the right food at homePeter McHenry, Paul R. Verkuil Professor of Public Policy and Economics and Department Chair
That savings gap is exactly what McHenry says workers tend to underestimate. He notes that when both grocery and restaurant prices rise together, the relative comparison between the two doesn't shift as dramatically as headlines suggest. The structural advantage of packing has been baked in for years — inflation just makes it more visible.
But McHenry is also quick to complicate the math. Economics, he says, is about understanding every consequence of a decision — not just the dollar amount at the register.
What's Your Lunch Worth?
Four quick questions to find your real cost — beyond the price tag.
How often do you think about nutrition when choosing your lunch?
- Almost always — Good habit. McHenry specifically calls out nutrition as a real consequence of the packed-vs.-bought decision — restaurant meals vary widely in content.
- Sometimes — Nutrition is part of the full economic picture. A $3 packed lunch can be healthier than an $18 sit-down meal, but it depends entirely on what you're packing.
- Rarely — I just want something fast — You're not alone, but the economist's framework applies here: nutrition is a resource you're either gaining or losing at every meal. It compounds over time just like dollars.
Do your coworkers regularly go out for lunch?
- Yes, most days — McHenry makes this exact point: eating at your desk alone versus joining coworkers at a restaurant is a real social cost. That relationship value doesn't appear on a receipt.
- Occasionally — A mixed approach may let you capture social connection on some days while packing on others — keeping the annual savings meaningful without the isolation.
- No, everyone does their own thing — If lunch is a solo affair either way, the financial argument for packing is even cleaner. The $3 vs. $18 gap faces no social friction in your situation.
How much time does it take you to prepare a packed lunch the night before or morning of?
- Under 10 minutes — Efficient prep is the key to making packing sustainable. At $3 a lunch versus $8-$18 out, even 10 minutes of prep time earns you a strong hourly return on that effort.
- 10–20 minutes — That time has economic value too — McHenry's core principle is to count every resource you give up. Twenty minutes a day, five days a week, is over 80 hours a year.
- I don't — it takes too long — Time is a real cost. But the $15 difference between a packed lunch and a sit-down meal might still justify it, depending on how you value your off-the-clock time.
Over the past year, grocery prices have risen by what percentage — more or less than restaurant prices?
- Groceries rose more than restaurants — Actually, restaurant prices climbed faster. Eating out rose 3.4% while groceries rose 2.7%, according to the U.S. Bureau of Labor Statistics — meaning the relative cost advantage of packing has actually grown slightly.
- They rose about the same — Close, but not quite. Restaurant prices (3.4%) outpaced grocery prices (2.7%) over the past year. Even a small gap compounds significantly across hundreds of lunches.
- Restaurants rose more than groceries — Correct. Eating out climbed 3.4% while groceries rose 2.7%, per BLS data. Fast food specifically rose about 3%. The gap between packing and buying has widened — not narrowed.
The big principle is just think about all of the consequences - money, time, just every resource that you give up when you make a decision, and that will help make up probably a better decisionPeter McHenry, Paul R. Verkuil Professor of Public Policy and Economics and Department Chair
Build a Smarter Lunch Strategy
- Know your real daily number — Use your calculator result above as your anchor. Whether it's $3 or $18 a day, seeing the annual figure makes the choice concrete — not abstract.
- Count the non-dollar costs — Time, nutrition, social connection — McHenry calls these real economic consequences. A lunch that costs $3 but leaves you eating alone every day has costs a receipt won't capture.
- Pick a sustainable mix — Full commitment to packing is the maximum savings play, but even packing 3 days a week and eating out 2 cuts your annual lunch spend significantly versus a daily restaurant habit.
- Watch the next CPI release — The next Consumer Price Index report is scheduled for August 12. It will update how grocery and restaurant prices are tracking — and whether the gap is widening or narrowing.
Why Comparing Grocery vs. Restaurant Inflation Is Tricky
When both grocery and restaurant prices rise at the same time, workers often assume the financial case for packing has improved. But as McHenry points out, that's not necessarily true — if both sides of the equation go up proportionally, the comparison barely moves.
What matters more is the structural gap: a $3 packed lunch versus an $8-to-$18 restaurant meal is not a close race. The ratio between those numbers is so wide that moderate price changes on either side don't close it. The August 12 CPI release will be the next opportunity to see whether that ratio is shifting in a meaningful way.
The U.S. Bureau of Labor Statistics tracks food-at-home and food-away-from-home as separate CPI categories — the divergence between those two lines is the number that matters most for this decision.
For Cleveland workers navigating a higher-cost world, the lunch decision is one of the few spending choices that repeats often enough to make a real annual difference. The economist's advice isn't complicated: count every resource — money, time, relationships, nutrition — and you'll make a better call.
The numbers in this story may shift when the Bureau of Labor Statistics releases updated CPI data on August 12. But the core math — $3 packed versus $8 to $18 out — has held up long enough that a single index report is unlikely to flip it.
