Price rise or pack shrink: which one, and when
Both moves bring in the same extra money per pack. But they play out very differently. They affect your sales, your shoppers' trust, your retailer relationships, and how easy it is to reverse course. This guide walks you through the choice before your next pricing review. It also explains why so many brands picked the wrong option between 2022 and 2024.
Your costs have gone up by 5 to 10% over the last six months. Your ingredients, packaging, or shipping have all got more expensive. Your brand is still strong and your product quality is fine, but you need to find about 5 to 8% more money per pack to keep your margin where it was. Your biggest retailer is pushing back on any price rise. Your category manager keeps asking why you do not just shrink the pack like the others did. This guide helps you choose between the two.
Same money in, very different outcomes
You charge more for the same pack. The number on the shelf goes up.
- What happens to your sales
- A 5% price rise usually costs you about 6% of your sales. That is the pattern across hundreds of studies in our industry.
- What shoppers notice
- Shoppers notice straight away. They see a new number on the shelf, and that number becomes their new benchmark for what your product should cost.
- How easy it is to undo
- Hard to take back. If you lower the price later, shoppers either think you were too greedy before, or that your brand is in trouble. The new higher price sticks in their minds for about 6 to 12 months.
- What your retailer does
- Your retailer sees the rise on every invoice. Expect your next yearly negotiation to be a lot harder. Your promo budget usually gets squeezed too.
- What it does to your profit
- Every extra dollar you charge flows straight into your profit. A 1% price rise is worth about 3 times more to your bottom line than a 1% sales gain. So if it sticks, the reward is big.
Use this option when your brand is stronger than the category average, when your current shelf price is not sitting right under a round number like $2.00 or $5.00, when you have a good relationship with your retailer, and when the cost rise is here to stay for at least 9 months.
You put less product in the pack. The price on the shelf stays the same, but shoppers get less for their money.
- What happens to your sales
- Making the pack 5% smaller usually only costs you about 3% of your sales. That is roughly half the hit of a straight price rise. This is the whole reason shrinkflation has become so common.
- What shoppers notice
- Shoppers usually do not notice straight away. They look at the shelf price, not the price per gram. You often get 2 to 6 weeks before someone calls it out, whether that is a retailer, a regulator, or a news outlet.
- How easy it is to undo
- Almost impossible to reverse. Putting the original size back means relaunching the product with new packaging, new barcodes, and listing fees from every retailer. Once you shrink it, it stays shrunk.
- What your retailer does
- Your retailer's invoice price does not change, so the year-end conversation stays easier. But when the buyer notices, they will treat it exactly like a hidden price rise and push back hard.
- Reputational risk
- This used to be an easy option. It is not any more. In 2023, Carrefour in France started putting warning labels on products that had shrunk. In 2024, France made it law: brands must put a disclosure label on the pack itself. Germany and the UK have consumer groups tracking it, and social media catches it too. The old 'they will never notice' argument is gone.
Use this option when your brand is a mainstream one with no real room for a price rise, when your current price is right up against a round number you cannot afford to cross, when your retailer is not actively shaming shrinkflation, when the pack you are shrinking is your everyday weekly-shop pack (not your entry-level or premium one), and when you have a plan for the day someone spots the change.
5 questions to ask before you decide
Is this cost problem going to last?
If the cost rise is only for one quarter (a bad harvest, a currency swing that will settle), neither raising the price nor shrinking the pack is worth the disruption. You can usually ride it out by pulling back on promotions or using a hedge. Only act if the higher costs look like they will stick around for 9 months or more.
Is your brand strong enough to charge more?
Compare your average shelf price to the category average. If you are selling at 20% or more above the average, shoppers already see you as worth it and you can get away with a price rise. If you are right in the middle of the category, a price rise risks losing shoppers to cheaper rivals. Shrinking the pack may be your only option in that case. But beware, the weaker your brand's pulling power, the worse the backlash if you get caught.
Which pack are you thinking of shrinking?
Your weekly-shop pack (the one most people buy as part of their regular groceries) handles a shrink best, because shoppers rarely check the grams. Your smallest entry-level pack is risky. If you shrink it, the price per gram jumps and shoppers will switch to a cheaper brand. Your biggest premium or gift pack is also off-limits, because part of what you are selling is the impression of plenty. Your value size multipack needs fresh numbers on whether it still looks like a good deal.
Is your biggest retailer naming and shaming shrinkflation?
If any of your top retailers is publicly flagging products that have shrunk (like Carrefour in France, or consumer groups in Germany and the UK), and if you are in a country with on-pack disclosure laws (like France since July 2024), the 'shoppers will never notice' argument is dead. In that case, a straight price rise is less risky than a shrink, even though it is a harder conversation at the negotiating table. This question often decides the whole thing on its own.
Is your current price sitting just below a round number?
Check the number on your shelf. If it is something like $1.99, $2.99, or $4.99, a price rise that pushes you over the next round dollar ($2, $3, $5) hurts a lot more than the size of the rise would suggest. Shoppers hate crossing those barriers. Shrinking the pack lets you keep the magic price point. If your price is sitting in the middle of a range (like $4.49, between $3.99 and $4.99), crossing a threshold is less of a worry and either option is fine.
Walk these 5 questions in order
A YES on any question takes you straight to the verdict on the right. A NO sends you down to the next question. Order matters. Earlier questions carry more weight than later ones.
Worked exampleOne concrete scenario, walked through the tree
One concrete scenario, walked through the tree
Picture a mainstream biscuit brand. Your 300g weekly-shop pack sells at $4.29. Each pack costs you $2.49 to make, so your margin is about 42%. Over the past year, the cost of cocoa, sugar, and shipping has pushed your total costs up by 9%, and that does not look like it is going away. Your brand sells at about 8% above the category average, so you are mainstream rather than premium. Two of your four biggest retailers are publicly flagging products that have shrunk. Your current price sits between two key round numbers, $3.99 below and $4.49 above. The pack you are looking at is your main weekly-shop size.
- Node 1YESWill this cost problem last 9 months or more?
Cocoa has been expensive for a year and a half because of supply problems in West Africa, and shipping has stayed costly too. This is not a one-quarter spike. Move to the next question.
- Node 2NOIs your brand selling at 20% or more above the category average?
Your brand only sells at 8% above the category average. That is not enough of a premium to absorb a price rise easily. Some room, but not much. Keep going.
- Node 3NOIs your price sitting right under a round number like $2.00 or $5.00?
Your price of $4.29 sits comfortably between the two key round numbers ($3.99 and $4.49). A 5% rise would take it to $4.50, just over the $4.49 mark. Not great, but not a disaster. Keep going.
- Node 4YESIs one of your big retailers publicly flagging shrinkflation?
Two of your four biggest retailers are naming and shaming products that have shrunk. The whole idea behind Option B (shoppers will not notice) no longer works in your market. **This one answer basically makes the decision for you.** Raise the price.
- Node 5YESIs the pack your everyday weekly-shop size?
Yes, it is your weekly-shop pack, which would normally handle a shrink well. But the retailer situation from the last question beats that. The decision stays as raising the price.
The verdict: raise the price to about $4.50, a 4.9% increase.
The retailer situation beats everything else. Even though the pack is the right one to shrink and your price position could handle it, you cannot risk a public shrinkflation label on your brand.
The maths backs it up. With a 4.9% price rise and a 42% margin, you can afford to lose up to 10.5% of your sales before you start losing money. The industry pattern says you should lose around 5.8%, so you have a safety buffer of about 5 percentage points.
Per pack, your revenue goes up by 4.9%. Because your costs only went up 9%, your profit per pack actually grows by about 9.5%. Across the whole brand, your total profit goes up by about 3.4%.
The price rise means a tougher year-end conversation with your retailer. But your brand stays off the next shrinkflation watchlist, and you keep the pack-size option in reserve for a future cost problem.
Carrefour and PepsiCo, 2023 to 2024: when shoppers start noticing
September 2023. Carrefour, the big French supermarket chain, did something unusual. They stuck paper labels on their shelves, right next to the products, calling out when a brand had shrunk the pack but kept the price the same. The list of products included Lay's, Lipton, 7UP, Quaker, and Tropicana from PepsiCo, Viennetta and Cif from Unilever, and Maggi, Quality Street, and Buitoni from Nestlé. The labels said, in plain French, that the product had reduced in size and the maker had put the price up. It was embarrassing for the brands.
January 2024. Talks between PepsiCo and Carrefour about the year ahead fell apart. Carrefour pulled PepsiCo products off their shelves in France, Belgium, Italy, and Spain. Lay's, Doritos, Lipton, 7UP, Quaker, and Tropicana all vanished from stores. The fight was publicly framed as a pricing and shrinkflation dispute.
Mid-2024. The two sides made a deal and most PepsiCo products came back to Carrefour shelves, with some concessions. A few lines stayed off. Both companies took a reputational hit, but it faded. The lesson behind the fight did not.
July 2024. France brought in a new rule. Starting 1 July 2024, brands have to put a label on the pack itself whenever they shrink it and the price per unit has gone up. So the old timing advantage (the weeks or months before shoppers noticed) disappeared overnight. Now shoppers see the warning on the pack, the first time they pick it up.
Shrinkflation used to be a quiet move. Back in 2019, you could shrink a pack and most shoppers would not notice for a long time. By 2024, three things made that much harder. Retailers themselves started flagging it, like Carrefour did in France. Governments passed laws forcing brands to put a warning on the pack, like France did in April 2024. And social media catches these things now, in a way you cannot opt out of. Put together, the old 'they will never notice' argument has stopped working in any market where even one of those three forces is present. That is why question 4 is the one you should think about the hardest.

How often, and what should make you re-decide
Come back to this every three months. The answers change over time. Whether your cost problem is still with you, whether your retailer has changed their stance on shrinkflation, and how your brand sits against the category, all move from quarter to quarter.
- One of your big retailers in your main market starts a shrinkflation watchlist. Go back to question 4.
- A government in your main market brings in an on-pack disclosure law, like France did in 2024. Go back to question 4 and rethink the reputational risk of shrinking the pack.
- Your brand's position against the category average shifts by more than 5 percentage points up or down. Go back to question 2.
- A direct competitor shrinks a pack that looks a lot like yours. Go back to question 4 and rerun the numbers on your worked example.
- The reason for your cost problem changes. Your hedge ends, or your currency position unwinds. Go back to question 1.
