What a week of dinners costs, measured every week.

How Bryti counts

The draw

For each household, Bryti draws a thousand weeks from Bryti's library under the household's rules, using a fixed seed. This means the weeks stay the same every month, but only the prices change. A week is included if all seven dinners have a price. The main number is the median of these weeks. Eight out of ten weeks fall within the typical range. Bryti weights the draw towards the dinners that Ipsos surveys from 2023 and 2025 show Norwegians cook most often. No recipe gets more than 15 of 100 weeks while there are other dishes to choose from.

What the number is, and is not

The number shows what a week of dinners from Bryti's library costs in the online shops Bryti checks. It is not a Norwegian average and does not reflect what an average family spends on dinner. Each chain is counted equally and is not weighted by market share. Neither KIWI, REMA 1000 nor Extra is included, because these discount chains do not show prices online. These are list prices from online shops, not what people actually paid at checkout. The number reflects the cost of the food eaten, not the packs bought. When enough households share their receipts, Bryti will also show the actual dinner cost at checkout.

The recipe set

The recipe set has versions. If it changes, Bryti connects the data series. The date is shown here.

Week and month

Bryti checks prices every Monday. The monthly number is the median of the weekly measurements that count. It is published on the first day of the following month.

One fixed product per ingredient

Each ingredient is matched to one fixed product at each chain, chosen once. Bryti selects what a typical family would buy, the chain's standard product or the market leader. It is not the cheapest, premium, or organic option. The same pack size is used across chains when possible. The form is also the same. If cod is frozen at one chain, it is frozen at all.

Kilos and grams

The price per kilo is multiplied by the amount in grams used in the recipe, adjusted for the household's portion size. If a pack size gets smaller, the price per kilo shows it on its own. When a shop only lists a price per piece, Bryti converts it to a price per kilo. Bryti uses a fixed weight per piece, with a source for the weight.

List price, offers included

The price shown is what anyone can pay online on the day Bryti checks, including ordinary offers. Member prices and multi-buy deals like “2 for 64” are not included. The date appears next to the number. Regular and offer prices are kept separate.

The median across chains

For each item, the price is the median of the chains that list a price. If only one chain sells an item, which is true of a few, that price is used. If the price per kilo varies by more than double between chains, the item is removed until someone reviews it. Bryti does not display prices by chain.

When an item is missing or replaced

If fewer than 90% of dinners have a price, that week's data is held back. It does not count for the month unless someone approves it. The same rule applies if fewer than 90% of weeks are fully priced. Except for the first month, if a month has fewer than two measurements that count, it is also held for review. If a product is no longer available, Bryti selects a replacement. The series is linked by comparing the old and new prices in any month where both are available. If this is not possible, a break is marked here with its date. A product is never swapped silently.
