Grocery Budget Calculator | Weekly Food Budget by Household Size | Offline HTML App | No Subscription

Stop guessing what groceries "should" cost.**

With food prices up dramatically since 2020, the #1 question at checkout is *"is this normal?"* This calculator answers it in seconds: set your household — kids, adults, seniors — pick one of four spending plans modeled on the USDA Food Plans, and your personal weekly and monthly grocery target appears instantly. A live traffic-light gauge then tells you at a glance, all week long, whether you're on track, drifting, or over.

No signup. No subscription. No spreadsheet formulas to break. One beautiful file that runs in your browser — even offline in the store, in airplane mode, with zero internet.

**HOW IT WORKS**

1. Download and double-click — the app opens in any modern browser (Chrome, Safari, Edge, Firefox) on desktop, laptop, tablet, or phone. Nothing to install.
2. Set your household on the Household tab: how many kids (0–11), adults and teens (12–64), and seniors (65+), then choose a plan — Thrifty, Low-Cost, Moderate, or Liberal. Your weekly and monthly targets calculate instantly, including the household-size adjustment, and re-calculate the moment anything changes.
3. Allocate your budget across Produce, Proteins, Dairy, Pantry, and Snacks (rename or add your own), then build your shopping list with estimated costs.
4. At the store, check items off and enter actual prices — the dashboard gauge and remaining budget update live. A one-tap printable list view gives you a clean paper backup.
5. When the week's done, tap "Start New Week": the whole week — total, variance, notes, and your full shopping list snapshot — archives to History, and a trend chart shows how you're doing over time.
