Home improvement and DIY pricing data

Data Purl tracks home improvement weekly across the major home improvement chains and online retailers: tools, hardware, building materials, paint, outdoor and garden. It shows price moves on identical products, promotional intensity around seasonal events, and each brand's presence across retailers.

What is tracked

  • Price changes on identical products, including imported categories exposed to tariffs
  • Promotional events and depth by category and retailer
  • Brand and private label assortment by retailer
  • Availability through seasonal peaks

Questions it answers

  • Are tariffs being passed through to shelf prices on imported tools and hardware?
  • How promotional are the big home improvement retailers versus last year?
  • Which tool brands are gaining or losing assortment at each retailer?

Key metrics

  • Matched-SKU inflation (same-SKU price change): The price change of identical products observed in both periods, which isolates true price moves from changes in product mix.
  • Markdown breadth: The share of each product's in-stock sizes and variants selling below full price, averaged across products so each product counts equally.
  • Share of shelf (online): A brand's share of the products a retailer lists in a category, measured on the retailer's website.
  • Price gap: The percentage difference between the price of one product or brand and a comparable alternative, such as branded versus private label.
