Reusable products are usually assumed to be cheaper long-term, but that isn't automatic. We worked out the real per-use cost on five common product pairs.

Where reusable clearly won
A safety razor versus disposable cartridges broke even within about two months and saved significantly after that. Cloth napkins versus paper ones paid back their cost within a few months of regular washing. Reusable coffee filters versus paper ones were cheaper within the first year.
Where it was closer than expected
- Reusable food wraps versus cling film took nearly a year to break even, given the upfront cost
- A reusable razor with premium refill blades wasn't meaningfully cheaper than budget disposables, only lower in packaging waste

The honest answer: reusable usually wins on cost eventually, but 'eventually' varies a lot by product, and it's worth doing the sum before assuming it applies to everything.
For more of this kind of testing, the eco-friendly product guides hub collects everything we've tried in that area.
Frequently asked
Do I need to buy anything to get started?
No. Every method here begins with what is already in your cupboards. We only recommend a purchase when something has genuinely worn out, and we say what it should cost.
How do you test the things you write about?
Minimum four weeks of ordinary household use, with notes. For anything involving energy or money we use a plug-in meter and record the readings before and after.
Are your recommendations paid for?
Never. Brands cannot buy placement. Some outbound links are affiliate links, which we mark, and they do not change what makes the list.
What if a method doesn't work in my home?
Write to us. A surprising amount of our best material comes from readers explaining why something failed in a flat, a shared house or a very cold winter.
