Home Depot vs Lowe's: Which Is the Better Buy in 2026?

The PRO versus DIY split defines the competitive dynamic. Home Depot earns roughly 50% of revenue from professional contractors; Lowe's historically earned more from DIY homeowners but has aggressively shifted toward PRO. The contractor customer is more valuable — higher ticket, more repeat purchases, and commercial-scale project demand that DIY can't match. Both depend on housing market health, but Home Depot's PRO tilt means it outperforms more directly when construction activity is strong.

Home Depot's contractor-focused business model gives it a margin and scale advantage that Lowe's has been methodically trying to close but hasn't yet reached. PRO contractor customers spend 3–5x what DIY customers spend per transaction and are stickier — once a contractor sets up a Home Depot account with credit terms, they rarely switch. Home Depot's supply chain investments and PRO loyalty program are ahead of Lowe's equivalent initiatives. But Lowe's has been executing well under current management, closing margin gaps that looked permanent a few years ago. Home Depot for quality and margin; Lowe's for the value trade on continued execution.
