☕ The Latte Factor
Live a week one day at a time, choosing whether to give in to each little temptation or skip it and invest the difference. Watch your skipped spending compound into a surprising nest egg — and learn why starting early, and finding balance, beats both splurging and self-denial.
The Latte Factor
Live a week, one day at a time. Every coffee, takeaway and impulse buy is a choice: treat yourself now, or skip it and watch the money compound into a small fortune by 65. Skip too much and you'll burn out — it's about balance, not misery.
40 years until 65 — the earlier you start, the more compounding does the work.
The finance behind the fun
The Latte Factor is a simulation, but every projection uses the same compound-interest maths as our calculators, so the numbers behave the way they would in the real world.
- Opportunity cost:the true price of a daily coffee isn't £4 — it's the much larger sum it would have grown into over decades. See it with our compound interest calculator.
- Start early: compounding rewards time above all else, so the same habit is worth dramatically more begun at 25 than at 45. Explore it with our savings goal calculator.
- Lifestyle creep: subscriptions and small recurring costs quietly compound against you until you cancel them.
- Balance over deprivation:sustainable saving beats extreme frugality you can't stick to — the score rewards a liveable middle.
Frequently asked questions
What is the latte factor?
The latte factor is the idea that small, regular discretionary purchases — a daily coffee, a takeaway lunch, an unused subscription — add up to far more than they seem once you account for what that money could have earned if invested instead. This game makes that opportunity cost visible by projecting every skipped purchase forward to age 65.
How is Future You calculated?
Each amount you skip is assumed to grow at a 7% real (after-inflation) annual return under the assumption that you repeat that same sacrifice once a month. The headline figure compounds your implied monthly saving rate forward to age 65 as an annuity — in other words, what you'd have if you kept up that habit once a month for the rest of your working life. The earlier you start, the more years compounding has to work, which is why the same habit is worth far more at 25 than at 45.
Why does skipping everything lower my score?
Because relentless deprivation isn't sustainable. Your happiness gauge falls every time you deny yourself, and if it bottoms out you crack and binge-spend — wiping out your discipline. Your final score multiplies your projected nest egg by your happiness, so a sustainable balance beats both reckless spending and joyless penny-pinching.
Do subscriptions really matter that much?
Yes — that's lifestyle creep. A subscription you sign up for keeps billing every month until you cancel it, quietly draining money you barely notice. A £15-a-month service kept for decades is thousands of pounds, and far more once you count the returns it could have earned. Cancelling the ones you don't use is one of the easiest wins in personal finance.
Is my progress saved?
Yes. The game saves to your browser automatically, so you can close the tab and pick up where you left off on the same device. Starting a new game clears the old save.
