How to Go Grocery Shopping Once a Month

Our family of five spends $500 a month on groceries with sanity completely intact

I do meal planning and one primary grocery trip a month, and I’ve been doing this since 2014. Grocery shopping once a month has a ton of benefits for our family and helps us in the following ways:

  • Save time—fewer grocery store trips.  
  • Save money—no grocery budget surprises plus the ability to buy in bulk
  • Less waste– fewer leftovers that get thrown out
  • Less stress—I never have to think about what’s for dinner before 4pm on any given day

I do pop into the store to pick up some produce (because I haven’t yet figured out how to make lettuce last a full month), but I don’t consider that “grocery shopping” as it requires no planning and doesn’t take more than 5-10 minutes (compared to hours).

Why I Started Grocery Shopping Less

This all started out of sheer necessity when my twins came along. Any mom of twins (or really anyone with eyeballs) could understand the logistical nightmare of two newborns accompanying you on a shopping trip. Two car seats take up the entire cart—there’s no room for food! When I would go grocery shopping, I’d end up pushing a cart full of children and pulling a cart full of food.

It didn’t take me many rounds of this real-life game of Tetris to realize it was time for a better solution. I tried grocery delivery after I’d been given a gift certificate, and I was determined to make those groceries last as long as possible. I started doing grocery delivery regularly (and then grocery pick-up when it became available). Each time, I’d get a little better at making a meal plan for the month and using up all the food we bought. I’ve learned a few things since I first started, and I’ll tell you my best tips for how to grocery shop once a month.

How to Go Grocery Shopping Once a Month

We plan out four to five dinners a week. Sundays dinners are with my in-laws or parents, and on Friday we get take-out. Lunches usually consist of leftovers from the night before or we have a short list of regular lunch options stocked (salad, pasta, sandwiches, soups, and quick instant pot options). When we don’t feel like cooking, we’ll have a quick meal like pasta, salad, or cheese and crackers.

We’ve found that planning out four to five dinners per week is the sweet spot for us. Here’s how I do it:

1. Plan Out the Meals

On the 25th of the month, I have a reminder set to plan my meals for the next month. This is my family’s chance to put in their requests (to stock up on or never make again). Then, I start by building a monthly list of meals that we want to eat, usually a mix of interesting things we’ve found throughout the month and of course some old favorites. We use Plan To Eat to store all of our recipes and meal plans, and there’s an easy drag-and-drop feature to do this—but you could also use any calendar of your choosing. I open my real calendar simultaneously and make sure that I don’t plan meals requiring a lot of prep on a day that we have swimming lessons, PTO, or other evening commitments.

A meal planning app or calendar makes grocery shopping once a month easier.

2. Make the Grocery List

Plan to Eat has a built-in shopping list generator, but you could also do this manually. Also, I realize this is starting to sound like a sponsored post, but I promise you it’s not! A lot of us here at YNAB just swear by Plan to Eat and it comes up whenever we talk about grocery shopping.

The shopping list generator is a great feature, because it puts the pieces together for you. Say you only need half an onion for one recipe and half for another, Plan to Eat keeps that tally. You can quickly see where your cost savings come into play—it’s quite magical when you see these efficiencies come together!

We also use our favorite handy devices (Echo Dots) to add to our shopping list throughout the month for things that wouldn’t necessarily be on the recipe list like condiments, peanut butter, spices, and snacks.

3. Order Online

Once I’ve got my grocery list, I order online. I bring up the website of my online grocery store of choice, fly through the list, and add everything to my virtual cart (except for produce and the things I’ll pick up at Costco). Before I place my order, I’ll add in the produce for the first week or two, depending on the item (well-stored vegetables will last longer than you may think).

4. Pick Up Groceries

On the first(ish) day of the month, we’ll pick up our groceries or get them delivered. The same day, we’ll run to Costco to supplement our dinner needs and pick up lunch and breakfast food. Here’s what a typical Costco list might look like.

We have a pretty standard set of options we’ll eat for breakfast and lunch so this list stays relatively the same each month. These options are actually listed out on laminated menus that our kids choose from each night before bed to pick out their food for the next day. My husband then preps lunches before bed (or well, he did when they were still going to school).

5. Quick Replenishing

Once our fridge is full, we usually wind up popping into our local market a couple times during the month for fresh produce, eggs, bread, and dairy. I don’t consider these stops as “grocery shopping” as they take a few minutes (rather than hours) and don’t require any of the pre-planning or mental decision making of true grocery shopping. These stops typically take no more than 5-10 minutes and cost around $20-$30 each.

In our grocery budget in YNAB, we have three category lines:

  1. Monthly Costco run: $250/month
  2. Monthly grocery shop: $150/month
  3. Grocery replenishing (for those quick market trips): $100/month

Benefits of 1x/Month Grocery Shopping

I don’t love grocery stores, and I don’t love grocery shopping. I’m not a person who is relaxed by a stroll through the aisles, and I’m not a person who thrives with on-the-fly planning (as you can probably tell by this system!).

For me, there are three huge benefits to grocery shopping once a month:


I can easily swap one meal for another in my meal plan because I have so many choices! If the weather is nice and we want to grill, I can swap burgers with soup and be confident I have everything we need.

Control Over Grocery Spending

When you grocery shop online, you see exactly how much your total will be. If things get a little crazy in your online cart, you can easily remove an item or rethink a meal to drop the total cost. You can also add a few treats (and not share with your family unless you want to) when you have a more budget-friendly month. Having a separate Costco line is really helpful for giving us a super clear framework for spending when we go.


I spend two to three hours total per month to meal plan, order, go to Costco (eat at the food court), and pop into a local market for milk. Many people might spend that much time each week on groceries and and meal planning. Here’s how it’s broken down per month:

  • 1 hour: meal planning and ordering groceries (often with the TV on and my favorite beverage in hand)
  • 1 hour: Costco trip and food court dinner (we get relatively the same things each trip, so it’s quick)
  • 30-45 minutes: replenishing (we have multiple market options that are on our normal school/work routes so each trip ends up being no more than 15 minutes and we usually stop two or three times a month)

Our Setup

We spend about $500/month for a family of five on groceries. We eat mostly vegetarian, and at the end of the month our meal options are a bit more limited, the fridge is empty, and our shelves are nearly bare. On the upside, we haven’t thrown away produce or stale/expired food in years and have virtually eliminated food waste in our family. We’ve found this setup to be smoother and tastier than frozen meals, and it doesn’t take up as much space in the freezer.

My husband and I split the cooking half and half, and this method helps us share responsibilities (you just check the app for what’s on the menu).

Reducing your grocery budget is a slow process. And, like we talk about all the time at YNAB, how you spend your money is truly unique to your family! The number of people you’re feeding, the area you live in, your personal eating habits, etc. will all factor into your grocery budget and you shouldn’t feel bad about that at all!

While our setup might not be enticing to everyone or fit with your specific needs, we have found it useful for dialing in our grocery spend and freeing up time and mental space every month.

*Author's Note: Since the original post, a few (exciting!) changes have occurred in our household—including that we're a family of 7 now. With the rising inflation rate, growth of our family, and increasing activities of our kids, we've made some financial adjustments. Our monthly food spend has now increased to $800 to accommodate our larger family, and we've also expanded our dining out category to cater to our more "on-the-go" meals during various activities. However, the fundamental principles and tips discussed in the blog post remain as relevant as ever, and we still use the same tried-and-true method for grocery shopping.
