What People Research Before They Buy: 25 Purchases, the Real Survey Numbers and What We Found in Each

You want the 25 most researched purchases. Here's the honest answer: nobody has published a verified ranking.

We looked. There is no independent, US, category-level ranking of research effort across these 25 purchases. There isn't one for most of them.

What does exist is smaller:

• A five-category ranking from a marketing agency, March 2026
• A nine-category ranking of who researches through reviews and photos, from a review-software company, September 2024, worldwide
• A three-group split on how many channels people check, from a product-content vendor, January 2026

Here's the five-category one. PartnerCentric surveyed 1,007 US consumers in late March 2026 and published it April 13:

The limits are real. It's a single marketing-agency survey. It didn't publish its question wording. It only covered five categories.

Only five of the 25 have a measured number. The rest are a shortlist.

So we won't call this the top 25. We'll call it 25 purchases where a wrong choice costs real money or comes up a lot. Then we checked each one for the facts that matter.

The list started as a practical shortlist, not a measured ranking.

Almost everybody researches something. Most don't take long.

In that same survey, 97 percent said they research in some capacity before they buy. 77 percent buy within a week of starting. 15 percent buy the same day.

Where do they look?

29 percent said an AI chatbot changed their mind about a purchase.

Two other numbers show how people behave in the middle of the trip:

• Baymard Institute's compilation of 50 studies from 2006 to 2025 puts documented cart abandonment at 70.22 percent. In Baymard's own study, 42 percent of US online shoppers abandoned because they were just browsing or not ready to buy.
• The National Retail Federation, with Happy Returns, projected 19.3 percent of online sales would be returned in 2025. That's $849.9 billion. It's all online sales, not a category.

Baymard's data is mostly vendor reports. The NRF's methodology isn't on the page.

Salsify, a product-content vendor, adds that 67 percent of shoppers research online and buy in a store, and 53 percent do the reverse. We couldn't see its sample size or dates.

The lesson is simple. People research. Not everyone researches deeply. Hardly anyone checks the contract.

Reviews are the habit. They've been the habit for a decade.

Pew Research Center's 2016 survey found 82 percent of US adults at least sometimes read online ratings or reviews before buying something for the first time. 40 percent always or almost always did. It wasn't split by product, and it's nearly ten years old.

BrightLocal's 2026 survey of 1,002 US adults found 97 percent read online reviews for local businesses. 41 percent always do, up from 29 percent the year before. 49 percent trust them as much as personal recommendations. BrightLocal sells local search software, so treat it as a vendor survey.

Bazaarvoice asked more than 8,000 consumers in seven countries which products they research through reviews, photos and video. It's a review-software company and the sample is worldwide:

Automotive came last. Car buyers read reviews least, at least in that survey. We'd bet they read the dealer's paperwork even less.

And reviews can be faked. The FTC's rule banning fake and bought reviews took effect October 21, 2024. The guides on skincare and makeup cover the case of managers writing reviews on a retailer's site.

Research should follow the money. Here's where households spend it.

The Bureau of Labor Statistics published its 2024 Consumer Expenditure Survey on December 19, 2025. Average annual spending per household was $78,535:

Those averages include households that bought nothing. Only 2.74 percent reported buying a mattress in the quarterly interview, and 5.38 percent reported buying a vehicle. Interview and diary items aren't comparable across rows.

The survey doesn't measure research. It just ranks the stakes.

Housing is a third of the budget. Cars are the next big buy. After that the list gets small fast.

That's why a mattress mistake costs less than a house mistake. And why the mattress guide is still worth reading: the trial can leave about 70 nights to decide.

Complaints show where buyers get burned. They don't show how often.

The FTC's Consumer Sentinel Network logged 6,471,708 reports in 2024. These are the categories that map to this list:

Those are counts, not rates. They're self-reported, unverified and include no-loss reports. Homes, insurance, mattresses and furniture have no matching category. We didn't retrieve the category definitions, so the television and computer lines may include software or media services.

The bigger number: the FTC said in testimony on March 25, 2026 that 3 million fraud reports in 2025 showed $15.9 billion reported lost. That's up from over $12 billion in 2024. It says actual losses are higher because few victims report.

The Consumer Financial Protection Bureau's 2025 report counted about 30,400 mortgage complaints and 28,500 vehicle loan or lease complaints. Those cover financial products only. The bureau says credit reporting complaints jumped because of misuse of the complaint process.

And the FTC said online shopping fraud was again the most commonly reported fraud category in which people of all ages said they lost money.

So the trouble is real. The data just can't rank it.

Small purchases take a week. Big ones take months.

Houzz's 2026 study of more than 20,000 registered users, fielded January to March 2026, reports kitchens at 9.5 months of planning and 5.8 months of construction. Closets took 6.6 months of planning and 4.3 of construction. Home offices took 6.1 and 3.4.

91 percent hired professionals. 75 percent set a budget. 37 percent went over it and 35 percent hit it. Houzz is a vendor and its users are self-selected.

Cars are older data. Cox Automotive's study, published May 15, 2019, covered 3,000 plus consumers including 331 certified pre-owned buyers. Those buyers averaged 85 days in the market and 14 hours 23 minutes researching. They spent 3 hours at the dealership. Half bought within 30 days. 32 percent were satisfied with how long it took.

That's a subgroup in a 2019 study. We couldn't open a current one.

Homes: the National Association of Realtors' 2025 profile, published November 4, 2025, had 6,103 responses from 173,250 buyers surveyed in July 2025. That's a 3.5 percent adjusted response rate. 88 percent used an agent or broker. First-time buyers were 21 percent of buyers, a record low, with a median age of 40.

NAR is a trade group of agents. We couldn't open the weeks searched or homes viewed.

If you're doing the home math, our home buying guide covers the real monthly bill.

These five have a measured research share. They're ordered by that share, and each guide starts from what we found, not from what the box says.

These seven have no measured research share we could find. Most of them are electronics, so the electronics number is the nearest proxy. That's our inference.

These seven live in your home. The data we found is mostly recalls, warranties and trial terms.

These four have the biggest bills and the longest contracts.

These two cost money every month, long after the box is open.

We wrote 25 guides. The same five traps came up again and again.

1. Price the total, not the sticker. On our math a console is about a third of a three-year bill. A $100 doorbell costs $350 over five years. A $2,000 treadmill costs $3,400 with the plan. A home's mortgage is barely half the real monthly bill.
2. Find the return fee before the return window. Peloton keeps $150 to $250 on a 30-day return. NordicTrack keeps $249.99. A mattress trial can leave about 70 nights to decide.
3. Find the cancel date. Salesforce and HubSpot contracts can't be cancelled mid-term. Software auto-renews unless you give notice. An alarm contract can charge 100 percent of what's left.
4. Check the recall record. The government's recall database lists about 55 dresser recalls since May 2024. Treadmill makers have paid or proposed penalties. Benzene hit sunscreens and acne products.
5. Ask who owes you the refund. Tickets bought from an airline are refunded automatically. Tickets from a booking site follow a separate process. A contractor's unpaid sub can lien your house.

There's a sixth thing, and it's the one nobody wants to hear.

Some of these facts will be stale in a month. Prices move. Rules move. Every guide has a date, a list of sources and a list of what we couldn't confirm.

Read those lists. They're the honest part.

Absence here is not proof that the data doesn't exist. Our research ran out of web-search budget partway through, and several likely sources blocked automated access.

What we didn't find:

• A verified ranking of the 25 most researched purchases
• Research-share numbers for 20 of the 25 categories
• Current car-buying studies from Cox Automotive
• Current car-buying studies from J.D. Power or Edmunds
• NAR's weeks-searched and homes-viewed numbers
• Category-level return rates and regret rates
• Shopping behavior for insurance, like how many people compare quotes
• Research data for headphones, cameras and vacuums
• Research data for mattresses, baby gear and business software
• Gartner, G2 and TrustRadius buyer reports
• A 2025 FTC Data Book. Only 2025 totals from testimony.

The sources we used for survey numbers are vendors or trade groups. We said so every time.

If you have a better source, send it. We'll add it to the right guide.

We read the surveys' own pages where we could open them, plus the Bureau of Labor Statistics, the FTC and the Consumer Financial Protection Bureau. We checked them on October 19, 2026.

The pages we used:

• PartnerCentric on impulse buying
• Bazaarvoice's Shopper Experience Index
• Salsify on 2026 consumer buying behavior
• Pew Research Center on online reviews
• BrightLocal's 2026 review survey
• Baymard Institute on cart abandonment
• The National Retail Federation on returns
• The Bureau of Labor Statistics' Consumer Expenditures
• The FTC's 2024 Consumer Sentinel Data Book
• The FTC's testimony on the scam economy
• The Consumer Financial Protection Bureau's 2025 complaint report
• The National Association of Realtors' 2025 buyer profile
• Cox Automotive's car buyer study
• Houzz's 2026 study

Some limits worth repeating:

• PartnerCentric describes its sample as weighted across generations while its intro says over 1,000. The page lists 1,007.
• Salsify's 39 percent for furniture is a share using two to three channels, so a lower number doesn't mean they research less.
• BLS percent reporting is quarterly for interview items and weekly for diary items.
• FTC category names may not match purchases exactly.
