Corded vs cordless power tools: which is cheaper to own?
The real cost of a cordless tool is rarely the tool — it is the battery platform you buy into and keep feeding for years. Corded tools sidestep all of that but tie you to a socket. Here is the honest comparison.
- No batteries to buy, degrade or replace — the big long-term saving
- Constant full power, never runs flat mid-job
- Only an extension lead and the odd brush or cable as upkeep
- Less convenient away from a socket, and a cable to manage
- Batteries that degrade and are the main recurring cost
- You are locked into one brand’s battery platform for future tools
- Sharing batteries across tools softens the cost if you stay in-platform
- Unmatched convenience and portability on site or in the garden

For occasional DIY near a socket, corded tools are the clear lower true cost: cheaper to buy and nothing to replace. Cordless wins on convenience, and its cost softens if you commit to one battery platform and share packs across several tools — but you are buying into years of battery replacements and a brand lock-in. Choose corded for value and heavy stationary use; cordless for portability, accepting the battery cost that comes with it.

Common questions
Usually yes to own — there are no batteries to buy, degrade or replace, and they cost less upfront. Cordless tools cost more over time because the batteries are a recurring expense and you are tied to one brand’s platform.
If you will own several tools, yes — sharing batteries across them spreads the cost and is the main way cordless makes financial sense. The trade is brand lock-in: your future tools are steered by the platform you chose.
The batteries. They degrade over years and are the priciest recurring part, and the platform lock-in shapes every future purchase. Counting only the tool, not the batteries you will keep buying, is exactly what makes cordless look cheaper than it is.
