A step-by-step plan to lower your grocery spending: benchmark against USDA food plans, shop by unit price, stack store apps and coupons, and avoid delivery-fee creep.

Key takeaways

  • Benchmark your spending against the USDA's monthly Cost of Food reports before you cut.
  • Unit price (price per ounce, pound or count) beats the sticker price every time.
  • Free store loyalty apps and digital coupons are the easiest savings most shoppers skip.
  • Delivery memberships only pay off if you order often enough to beat the fee.

Step 1: Know what ‘normal’ costs for your household

Before trimming, find out whether your grocery spending is actually high. The U.S. Department of Agriculture publishes monthly Cost of Food reports for four food plans: the Thrifty, Low-Cost, Moderate-Cost and Liberal plans. Each one prices a healthy diet of meals and snacks prepared at home, and the costs are updated every month for inflation using the Consumer Price Index.

The reports list weekly and monthly costs by age and sex for individuals in a four-person household, with suggested adjustments for other household sizes (for example, add 20 percent for a one-person household and subtract 5 percent for a five- or six-person household). Add up the figures for everyone in your home, apply the adjustment, and compare the total with your last two or three months of grocery receipts.

If you are far above the Moderate-Cost plan, the steps below will likely save you real money. If you are already near the Thrifty plan, focus on the free tools in Step 4 rather than cutting further.

Step 2: Plan meals around what is on sale

  • Look at your store’s weekly ad first, then plan three or four dinners around the proteins and produce that are discounted.
  • Write a list by store section and stick to it; unplanned purchases are where budgets leak.
  • Plan one ‘use it up’ night each week to cut food waste.
  • Cook once, eat twice: double recipes that freeze well.

Step 3: Shop by unit price, not sticker price

Shelf tags at most large grocers show a unit price, such as cents per ounce. Compare that number, not the package price. Bigger is usually cheaper per unit, but not always, especially when a smaller size is on sale. Store brands are often the lowest unit price for staples such as flour, sugar, canned vegetables, frozen produce and cleaning supplies.

Step 4: Use free store programs and digital coupons

Most chains now put their best prices behind a free account. A few examples from the stores we cover:

  • Target: free Target Circle deals, plus an extra 5% off with the Target Circle Card, which stacks on top of Circle deals.
  • Walmart: stores will match the price of an identical item advertised on Walmart.com, and accept paper manufacturer coupons that scan.
  • Dollar General: digital coupons added to your myDG account, redeemed with your phone number.
  • CVS and Walgreens: ExtraCare and myWalgreens rewards on household basics.

Our coupon stacking guide explains how to combine store and manufacturer coupons legally.

Step 5: Watch delivery and pickup costs

Delivery is convenient, but fees, service charges, tips and sometimes higher item prices add up. Instacart, for example, lists Instacart+ at $99 a year or $9.99 a month, with $0 delivery fees on grocery orders of $10 or more. That only pays off if you order often. Free curbside pickup, where offered, avoids delivery costs entirely. See our delivery and takeout guide.

Step 6: Check if you qualify for help

If money is tight, see whether your household qualifies for SNAP. The USDA’s SNAP eligibility page explains the rules and how to apply in your state. Some retailers also discount memberships for people who receive government assistance, such as Walmart+ Assist and Amazon Prime Access.
