40 weekly alcohol spend over 30 years at 7% compounds to roughly 211,400. Not advocating abstinence — showing the cost side so the enjoyment can be weighed against the lifetime opportunity cost. Hybrid reductions (lower-budget options, sober weeks) capture half the saving with less sacrifice.

Run it with sensible defaults

Using weekly alcohol spend of 40, annual return of 7%, years of 30 years, the calculation works out to 211,445.37. Nudge the inputs toward your own situation and the output recalculates instantly. The defaults are meant as a starting point, not a recommendation.

The levers in this calculation

The inputs — Weekly Alcohol Spend, Annual Return, and Years — do not pull with equal force. Frequency and unit price pull the total in different directions. The biggest surprise for most people is how small recurring amounts compound into large annual figures — that's where this calculation earns its keep.

How the math works

Weekly × 4.333 = monthly. FV of monthly annuity. The working is transparent — you can verify every step yourself in the formula section below. No black box, no opaque "proprietary model".

Reading the result without judgement

The figure isn't a scorecard. It's a prompt — something to sit with for a few days before deciding whether any habit needs changing. Reflexive reactions ("I need to cut everything") usually don't last; considered ones do.

What this doesn't capture

Behaviour-adjacent math is always an approximation. Human habits are lumpy and context-dependent; the figure here assumes steady behaviour which is a simplification. Treat the output as a prompt for thinking rather than a precise prediction.

Related calculations worth running

Plans get firmer when you triangulate. Alongside this one, the sober curious savings calculator, the alcohol spending annual calculator, and the cafe weekly compound calculator tend to come up in the same conversations. Running two or three together exposes inconsistencies in any single assumption — which is usually where the useful insight lives.

Frequently Asked Questions

Realistic weekly spend?
households average 12-40/week. Heavy social drinkers 60-150.
Should I include restaurant wine?
Yes if significant. Wine with meals out often the biggest alcohol expense for moderate drinkers.
Sober-curious alternatives?
Alcohol-free options typically 30-50% of alcoholic equivalent. Halving doesn't remove all cost but captures most.
Dry January impact?
One month's savings compounds like a larger lump sum. A single January of abstinence compounded over 30 years at 7% is meaningful money.
