How to read a grocery receipt, line by line

Most people glance at the total and fold the receipt into a pocket. That is how you miss a member price that didn't ring up, a bag of tomatoes weighed twice, or a tax charge on something that shouldn't be taxed. Reading a receipt properly takes about two minutes once you know what each part means.

Below is one example receipt from a US grocery store. It has the parts that confuse people: shortened names, weighed produce, a multi-buy, a member saving, tax letters and a cash payment. We'll go through it from top to bottom.

01The header and the lines you can skip

The top of the receipt tells you where and when. The store name, the date and the time are the parts worth keeping: you need them for a return, and they are how you match the receipt to a card charge later. The register number, cashier number and long transaction codes matter only if you go back to the store with a problem. Keep the paper; you don't need to read them.

Receipts often print barcodes or item numbers beside each name. Those identify the product in the store's system. They are not quantities and they are not prices, so ignore them when you add things up.

02Decoding abbreviated item names

Register screens give each product a short name, so stores squeeze vowels out and cut words down. Most can be read by saying them out loud. Size and count usually sit at the end of the name.

When a name won't decode, check the price against the shelf tag or the store's app. A line you can't match to anything in your bag is worth asking about before you leave the parking lot, because it may be someone else's item or a double scan.

03Weighed items and unit prices

Produce sold by weight prints three numbers: the weight, the price per pound and the line price. The line price is the weight times the per-pound price, rounded to the cent. On the example, the bananas are 2.14 lb × $0.69 = $1.4766, which rounds to $1.48. The tomatoes are 1.37 lb × $1.99 = $2.7263, which rounds to $2.73. Both check out.

If a weighed line looks high, the weight is the first thing to check. A bag of three bananas doesn't weigh five pounds. A per-pound price that doesn't match the shelf usually means the item was keyed in under the wrong produce code.

Unit prices are also the fairest way to compare shopping trips. The cereal works out to $6.00 for 24 ounces, or 25 cents an ounce. The paper towels are $11.99 for six rolls, about $2.00 a roll. Write those down and next month you can tell whether a price went up or the package got smaller. Our guide to tracking grocery price increases builds on exactly this.

04Multi-buys, member prices and coupons

Savings usually print as a negative line right under the item they belong to. On the example, the eggs ring up at $4.19 and a member saving of $0.50 comes straight off, so the eggs really cost $3.69. The cereal is two boxes at $3.49, which is $6.98, and the multi-buy line takes off $0.98 to bring the pair to the advertised $6.00.

This is where receipts most often go wrong. If the shelf promised a deal and no negative line appears under the item, the promotion didn't ring up. Point to the line at the service desk; that's much easier with the receipt in hand than after you've unpacked.

Some coupons come off the whole bill instead, printed after the items near the subtotal. And many receipts end with a "You saved" figure. That number is a summary of savings already taken off above it. Don't subtract it again.

05Tax letters and the tax line

The letter after each item is a tax code. On this receipt, F marks food that isn't taxed and T marks a taxable item. Chains use their own letters or numbers, but the idea is usually the same: the code tells you which rate, if any, applied to that line.

Which groceries get taxed depends on where you live. In Texas, for example, the state comptroller says food products such as bread, milk, eggs, fruits and vegetables are not taxable, while soft drinks, candy, paper items, and soap and detergent are. That is the split on the example: milk and bread are F, while the cola, paper towels and dish soap are T.

US stores often add sales tax at the bottom rather than including it in the shelf price. You can check it yourself. The three taxable lines come to $7.49 + $11.99 + $3.29 = $22.77, and $22.77 × 8.25% = $1.8785, which rounds to $1.88. That matches the tax line. If a food item carries a T, or the tax is larger than your taxable lines can explain, ask.

06Subtotal, total and the payment line

The subtotal is every line added up, savings included. On the example: $3.89 + $4.99 + $4.19 − $0.50 + $1.48 + $2.73 + $6.98 − $0.98 + $7.49 + $11.99 + $3.29 = $45.55. The total is the subtotal plus tax, minus any whole-bill coupon: $45.55 + $1.88 = $47.43. That is what you paid.

Below the total, the payment line says how you paid. With cash, it shows the amount you handed over and your change: $50.00 tendered, $2.57 back. Neither of those is what you spent. With a card, you'll often see the card type, the last four digits and an approval code. Match the total, not the tendered amount, to your bank statement.

Watch for small charges that aren't products, such as a bag fee or a bottle deposit. They are real money and they belong in your total, but they won't match anything in your bag.

07A two-minute check before you leave

1. 1Count the lines against your bag. An extra line is a double scan; a missing one is a free item you should mention.
2. 2Look for a negative line under every deal you expected: multi-buys, member prices, digital coupons.
3. 3Check one weighed item: weight × per-pound price should give the line price.
4. 4Scan the tax letters. Staples marked taxable, or a tax line bigger than your taxable lines allow, are worth a question.
5. 5Confirm the total, not the cash tendered, is the number you'll record.

Doing this at the store is the point. A missed promotion is easy to fix at the service desk and awkward to fix a week later. After that, keep the receipt with your others; our guide on organizing receipts covers where.

08How Sorayli records the same receipt

When you scan this receipt with the Sorayli receipt scanner, it reads the lines for you, and you check the result before anything is saved. It writes the shortened names out in plain words. It records each weighed line as one item, with the weight as the quantity. It folds the member saving into the eggs and the multi-buy into the cereal, so each line shows what that item actually cost. The F and T letters are dropped, since they are codes, not amounts. It suggests a category for each line, and you can change any name, amount or category before you save.

Two limits are worth knowing. First, Sorayli reads the subtotal and tax and uses them to check the receipt's arithmetic, but it does not add sales tax to the item lines. On a US receipt like this one, the saved lines come to $45.55 while you paid $47.43. If you want your records to match what left your wallet, use Add item on the review screen and enter the tax as its own line. On the web, the review screen also shows the $1.88 gap between the items and the total, so it is hard to miss.

Second, a coupon taken off the whole bill is spread across the items in proportion to their prices only when the item lines add up to the total plus the coupon, which is how receipts with tax already in the prices work. When sales tax is added at the bottom, the tax usually keeps that check from passing and the items keep their printed prices, so compare the line amounts with what you paid before saving. Because every line is kept separately, the scanned receipt also makes it simple to split a grocery bill with roommates by hand.
