Why the guess is usually wrong
Ask someone what they spend on food and they'll give you their grocery bill. The rest is scattered: lunch on a work card, takeout through an app, coffee on whatever was in reach, a warehouse run on a different card. No single bank app sees all of it, and a statement shows charges by date, not by what they were for.
An AI agent with read-only access to all your accounts can read a year of charges in one pass and group them. With BankBridge connected to Claude, ChatGPT or another MCP client, that's one message.
Ask it
What did I spend on food per month over the last 12 months? Split it into groceries, restaurants, delivery apps and coffee, and give me the monthly average for each.

Every transaction carries two categories: a primary one like food and drink, and a detailed one like groceries, restaurant, fast food or coffee. The agent pulls a year of transactions with list_transactions and groups them by the detailed one. A plain spending summary by category gives you the food total in one number, but not the split, because it groups on the primary category only.
The demo household's food year
From the BankBridge demo account (a made-up household with fictional data), October 24, 2025 to October 24, 2026, pulled 2026-10-24:
| Type | Charges | 12 months | Per month |
|---|---|---|---|
| Groceries | 49 | $7,110.91 | $592.58 |
| Restaurants (incl. delivery) | 60 | $1,605.47 | $133.79 |
| Fast food | 48 | $890.19 | $74.18 |
| Coffee | 36 | $246.92 | $20.58 |
| All food | 193 | $9,853.49 | $821.12 |
Groceries are 72% of the total, all at one store, about once a week at $145 a trip. Eating out (restaurants, fast food and coffee) comes to $228.55 a month across 144 smaller charges. That's the usual shape: a few big grocery charges you remember and many small ones you don't.
How it compares with the US average
The Bureau of Labor Statistics' Consumer Expenditure Survey reports what the average US household (a "consumer unit") spent in 2024:
| US average, 2024 | Per month | Demo household | |
|---|---|---|---|
| Food at home | $6,224 | $519 | $593 |
| Food away from home | $3,945 | $329 | $229 |
| All food | $10,169 | $847 | $821 |
Source: BLS, Consumer Expenditures in 2024 (released December 19, 2025). The demo household lands close to the average overall, but leans toward cooking: more at home, less out. The average covers households of every size, so compare yours by shape (how the split falls) as much as by total. To ask the agent directly:
Compare my monthly food at home and food away from home with the US 2024 averages of $519 and $329. Which one am I further from?
Where delivery lands
Restaurant delivery is usually categorized as restaurant spending. In the demo year, DoorDash ($328.10) and Uber Eats ($270.08) sit inside the restaurants line, so $598.18 of the $1,605.47 was delivered. If you want delivery as its own line, say so:
Of my restaurant spending in the last 12 months, how much went through DoorDash, Uber Eats or another delivery app, and how much was in person?
For one app in detail, see how much you've spent on DoorDash or on Uber and Uber Eats.
Things that skew the number
- Big-box stores. A Target or warehouse-club charge with groceries and household goods on one receipt gets one category for the whole charge, usually general merchandise. Your food number can come out low if you buy a lot of groceries there. Ask the agent to list superstore charges so you can decide how to count them.
- Credit card payments. Paying a card from checking is a transfer, not food. The agent counts the card's purchases, not the payment, so nothing is counted twice. Our guide on double-counted card payments explains why that matters.
- Shared bills. If a partner or roommate pays you back for groceries, the repayment shows up as money in. Ask for net food spending after transfers from that person.
- Pending charges. Restaurant charges often post a few days later, sometimes with the tip added. Ask for posted charges only when you want a final monthly figure.
Using the number
Once you have the monthly figures, the useful questions are about change:
Food spending by month for the last 12 months, groceries and eating out as separate columns. Flag any month more than 20% above its average and tell me what drove it.
If you're turning it into a limit, our guide on building a budget with Claude sets categories from what you spend, and don't project from one month explains why the 12-month average is the number to plan with.
