How much alcohol adds up over a week?

“A glass with dinner” sounds harmless, but the week adds up. We turn beer, wine and spirits into units and calories and show where you sit against the low-risk anchor.

0.5 L glasses/week
150 ml glasses/week
40 ml shots/week
6.9 units/wk · 386 kcal

≈ 6.9 units a week — within the low-risk anchor (up to 14). That's ≈ 386 kcal a week of "liquid" calories. Keep 2–3 drink-free days in a row and don't save it all for one night — the pattern matters more than the total.

Source: UK Chief Medical Officers' guideline — up to 14 units a week, spread out, with drink-free days. 1 unit = 8 g ethanol ≈ 56 kcal. Units per serving are averaged over typical strength; lower is always better.

How to use the result

How it works

We convert each drink's volume and strength into grams of pure alcohol, and count the approximate calories along the way.

How to read the result

No risk-free level is established; less means lower risk. The calculator shows amount, not permission to drink.

Limitations

Avoid alcohol in pregnancy, driving, with certain medicines and conditions. Seek support if control is difficult.
