Setting a grocery number you'll actually keep
By this point the envelope's part of your routine — cash for groceries and eating out, kept apart from everything else — and you know why: that's the leaky category, that's where the forty-dollar milk run happens. But I stepped past something on purpose, and now it's time to go back for it: how much goes into the envelope in the first place.
This is the part people get wrong in two opposite directions. Either they guess low because they want the budget to look good on paper, or they guess high because they're afraid of running out mid-month and having a hard week. Both are guesses, and I'm not fond of guesses. We're going to build your number instead.
Start with what you actually spent, not what you wish you spent
Pull out three months of receipts if you kept them, or three months of bank and card statements if you didn't. Go through and lift out every grocery charge and every restaurant charge, and write them on your pad, one line each, with a running total at the bottom. Don't sort them into "good" and "bad" spending yet. Just get the real total for each of the three months.
I know this part is tedious. I once did it for three full months, every single receipt, because I didn't trust my own instinct about what those "quick stops" were costing us. As it happened, I was right not to trust myself — but you won't know that about your own numbers until you look. So please look.
Now average the three months. That average is your starting point. Not your final number — your starting point.
Adjust for what you know is coming
If one of those three months held a holiday, a birthday party, or a big Costco run for paper goods that's really "stocking up" more than "groceries," decide whether that was normal or a one-time bump. Don't just discard it because it's inconvenient — that's how people end up under-budgeting all over again. But if it genuinely won't repeat, note it on the pad and adjust your average down a little.
Split the number, on purpose, before the month starts
Here's where I'd like you to do something a lot of people skip. Decide right now, in ink, how much of that total is groceries and how much is eating out. Two separate lines. Two separate amounts, even if it's still one envelope, or two envelopes side by side.
Why split it? Because "food money" as one blob is far too easy to justify. If it's all one pile, a week where you eat out three times quietly swallows the money meant for groceries, and you don't notice until the pile's gone and you're puzzled about how. Separate lines let you watch it happen while there's still time to do something.
Build the fry sauce in on purpose
And this is the part I most want you to hear, because it's the opinion I hold hardest in this whole class. A food budget with nothing fun in it does not survive. I've never once seen it survive. You'll white-knuckle it a couple of weeks, and then one Friday you'll be tired and the kids will be whining and you'll blow the whole thing on takeout, because there was no plan for takeout — there was only "no."
So put the fun into the number. On purpose. In writing. Decide there's eighteen dollars, or thirty, or whatever fits, set aside for a burger and fries out, guilt-free, already accounted for. That isn't a leak, it's a line item. There's a real difference between money that vanished and money you meant to spend.
Rodney and I once ran the opposite experiment, on purpose — a full no-eating-out year, we called it — and we made it eleven months on pure willpower. Eleven months. And what finally broke us wasn't a birthday or a bad week or a crisis. It was two people who wanted a burger and fries like ordinary human beings, and fry sauce, and we cracked over something that would have cost us six dollars if we'd only budgeted for it from January. I count the eleven months as a win. But I also count it as proof — you can white-knuckle for a while, but sooner or later the fry sauce wins, so you may as well let it win on your terms and your dollar amount, rather than in an ambush on some random Tuesday.
Write the final number down and commit to it for one month
Groceries: one number. Eating out, fun included: one number. Both on the pad, both funded by cash in the envelope. Not a goal, not an aspiration — the actual amount you're going to hand yourself for the next four weeks.
One caution here, plain and simple: don't set the number so tight, out of guilt, that you're setting yourself up to fail in week two. A number you can't actually live on isn't discipline, it's just a budget you'll blow through and then feel bad about — and feeling bad about money has never once made anybody better at it. Better to set it a little honest and adjust down next month, once you've proven to yourself you can hit it.
Before next time
Get your three-month average done and split into groceries and eating-out, with your fry-sauce line already built in, and bring your pad — next time we're talking about what happens when the envelope runs dry before the month does.
