10/week × 40 years at 7% alternative return: 52,000 direct spend, 108,000 opportunity cost (invested instead) — 160,000 foregone. Odds of Lotto jackpot 1 in 45 million. Consistent lottery spend silently erodes retirement savings.
Quick example
With weekly spend of 10 and years of 40 (plus alternative return of 7%), the result is 114,501.86. Change any figure and watch the output shift — it's often more useful to see the pattern than to memorise the formula.
Which inputs matter most
You enter Weekly Spend, Years, and Alternative Return. 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.
What's happening under the hood
Future value of weekly annuity. The formula is listed in full below. If the number looks off, you can retrace the calculation by hand — that's the point of showing the working.
Why the behavioural angle matters
Most personal finance mistakes are behavioural, not mathematical. You know the math; the hard part is acting on it consistently. Calculators like this one are useful because they externalise a private feeling into a public number — and public numbers are easier to argue with than vague feelings.
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.
Where to go next
This calculation rarely sits alone in a planning exercise. If you're running these numbers, you'll probably also want the compound interest calculator, the habit streak value calculator, and the alcohol lifetime cost calculator — each one answers a different question in the same territory. Treating them as a set rather than in isolation usually produces a more honest picture.
