Home Depot vs Lowe's prices: which is actually cheaper?

By Simon Lafortune, Co-founder, Buildsavr · July 3, 2026

It is the question every builder asks before a big order: is Home Depot or Lowe's cheaper? People want one answer, one store to default to, so they can stop thinking about it.

Here is the honest answer: neither one is cheaper on everything, and picking a favorite store is exactly how you overpay. The store that wins on lumber loses on fasteners. The one with the best price on drywall is pricey on paint. The real question is not which store, it is which store for each item, and that is a question you can actually answer.

the cheapest store changes line by line

prices move, so last month is no guide
One list

Why 'which store is cheaper' is the wrong question

Home Depot and Lowe's are close competitors, which is the whole point. They shadow each other on headline items and make their margin on the rest. So neither can be cheaper across the board, by design. If one were clearly cheaper on everything, the other would not survive.

What actually happens is per item. On any given week, one store has the better number on framing lumber, the other on sheathing, a third category swings back. Add in fasteners, hardware, concrete, insulation, and finishes, and the "cheapest store" for a full list is a patchwork, not a single logo.

Prices also move. A great price last month tells you nothing about this week, and it is not the same from one region to the next. So even if you did the homework once, it goes stale fast.

What the honest comparison looks like

Pick any real project list and price it at both stores, item by item, and the pattern shows up immediately. Some lines are cheaper at Home Depot, some at Lowe's, and the gap on individual items is often bigger than people expect.

Buy the whole list at whichever store you defaulted to and you pay its price on every line, including the ones it runs high. Split your buying by the cheaper store per item and the same list gets cheaper, with no change to what you are building. The catch is that pricing a full list across two stores by hand, and keeping it current, is more work than anyone will actually do before a Saturday build.

How to find the cheapest store for each item automatically

This is exactly what Buildsavr does. You give it your list however you have it, typed, a photo, an Excel or PDF, or just by chatting, and the AI plan reader matches every item and prices it across every major retailer near you at once. Then it hands you a buying plan: the cheapest store for each line, your total, and how much you save versus buying everything in one place.

It is bigger than two stores, too. Home Depot and Lowe's are the giants, but regional chains and local yards often undercut both on specific items, and a good comparison includes them instead of pretending the whole market is two logos.

We already prove this in Canada

Buildsavr is live in Quebec today, and it is the same idea running against the same kind of matchup. Up here the two big boxes are Home Depot and Rona (Rona is Canada's national chain, and was owned by Lowe's Canada until it was sold in 2023), alongside strong regional players like Canac, BMR, Patrick Morin, and Home Hardware.

On a real list, no single one of those wins every line, exactly like Home Depot vs Lowe's in the US. Buildsavr prices the whole list across all of them at once and returns the cheapest store per item in about 30 seconds. That is the engine we are bringing to the US, where the headline matchup becomes Home Depot vs Lowe's plus your regional stores.

The takeaway

Stop looking for the one cheaper store. It does not exist, and chasing it is how you overpay. The builders who save the most are not loyal to Home Depot or to Lowe's. They price each item where it is cheapest, and they let a tool do the pricing so it is actually worth doing on every list.

Frequently asked questions

Is Home Depot cheaper than Lowe's?
Not across the board. Home Depot and Lowe's are close competitors and neither is cheaper on everything. On any given list, some items are cheaper at Home Depot and others at Lowe's, and the cheapest store changes item by item and week by week. The way to save is to buy each item wherever it is cheapest, not to pick one store.
Who has cheaper lumber, Home Depot or Lowe's?
It depends on the week, the region, and the exact product. One store often has the better price on framing lumber while the other wins on sheathing or pressure-treated. Because lumber prices move constantly, the only reliable answer is to compare the specific items you need at the moment you are buying.
How do I compare Home Depot and Lowe's prices on a whole list?
Instead of pricing each item at both stores by hand, give your list to Buildsavr (typed, photo, Excel, PDF or chat). Its AI plan reader matches every item and prices it across every major retailer near you at once, then returns a store-by-store buying plan with the cheapest place for each item. It is live in Quebec and expanding across Canada and the US.
Should I only compare the two big-box stores?
No. Home Depot and Lowe's are the giants, but regional chains and local lumberyards often beat both on specific items. A real comparison includes them. Buildsavr prices your list across every covered retailer near you, not just the two big boxes.
Is Rona the same as Lowe's?
Not anymore. Rona is Canada's national home-improvement chain and was owned by Lowe's Canada from 2016 until it was sold to Sycamore Partners in 2023, so it now operates independently. In Buildsavr's live Quebec market, Rona plays the role Lowe's plays in the US: one of two big boxes that trade wins with Home Depot line by line, which is exactly why comparing item by item beats defaulting to one store.

Stop guessing which store is cheaper. Price the whole list.
