Plain-English why
Copyable takeaway
What this means
No waffle. Just the number and how it was worked out.
Formula used
Weekly waste cost per category × household size × 52 × years remaining.
Worked example
A two-person household throwing away some fresh produce and regular cooked food wastes roughly £20/week — £1,040/year, over £40,000 across an adult lifetime.
Common questions
Why does the lifetime figure look so large?
Because food waste is a recurring cost that compounds over decades. The weekly number looks small; the 40-year figure makes the habit visible in a way that tends to actually change behaviour.
