Groceries are the budget line that breaks most often, because it's the one we spend on every few days. A number pulled from thin air rarely lasts a month. Here's a way to set one that holds.
1. Start from what you really spend
Add up the last 2-3 months of grocery receipts or card transactions and divide by the number of months. That's your honest starting point, not the number you wish it was.
2. Separate food from everything else
Supermarket receipts often include cleaning products, toiletries, pet food and household items. Split them out. Many people find their "food" spending is 20-30% lower than the receipt total suggested.
3. Turn the monthly number into a weekly one
A monthly budget is easy to blow in the first two weeks. Divide by 4.33 and track weekly. If one week runs over, the next week absorbs it, instead of discovering the problem on the 28th.
4. Plan meals around what's already at home
Before each shop, check the fridge and pantry and plan a few meals that use what's there. Food that gets thrown away is the most invisible part of a grocery bill.
5. Treat bulk buys as a separate category
Stock-up trips (warehouse clubs, big sales) can cover weeks of supplies. Log them as "stock-up" so one big receipt doesn't make the weekly budget look broken, and only buy in bulk what you actually use before it expires.
6. Cut by 5-10%, not 50%
Once you know the real number, lower it a little at a time. A 10% cut that sticks is worth far more than a dramatic target that's abandoned after two weeks.
