How Much Could You Save?
Small daily spends — the coffee, the pack of cigarettes, the takeout — barely register one at a time. Added up over a year, and especially invested over a lifetime, they're staggering. Pick a habit below and see what it's really costing you.

Why small habits cost so much
A single $6 coffee is nothing. The same coffee every workday is a few hundred dollars a month, and every day is over $2,000 a year. That's the first surprise. The second — the one that changes behavior — is what that money could become if you didn't spend it.
Money you save doesn't just sit there; invested, it compounds. The author David Bach called this the "latte factor": the idea that trimming a small daily expense and investing the difference can quietly build a fortune, because you're adding decades of compound growth on top of the money itself. In the default example, a daily coffee is about $44,000 of actual money over 20 years — but roughly $95,000 once it's invested.
This isn't about never enjoying anything
The point isn't that coffee or a night out is "bad." It's that seeing the real, long-term price tag lets you choose on purpose — keep the ones you love, cut the ones you don't really notice, and put the difference toward something that matters more. That's the whole idea behind a budget: spend with intention instead of by accident.
Quitting smoking or drinking: the financial bonus
If you're trying to quit smoking or cut back on alcohol, the health reasons are reason enough — but the money is a powerful extra motivator, and a daily reminder of progress. A pack-a-day smoking habit runs around $2,900 a year at average prices (much more in high-tax states), and invested over 20 years that's roughly $127,000. Drinkers cutting four nights out a week can free up $2,500+ a year. Many people find that watching the "if I'd quit" number grow is one of the most motivating parts of stopping.
What changes the number
- Frequency. Daily habits dominate — a weekly treat costs a seventh of a daily one.
- Your investment return. Whether the saved money sits in cash or is invested makes an enormous difference over decades — that gap is the latte factor.
- Time. Compounding rewards patience: most of the growth happens in the final years, which is why starting now matters far more than the amount.
- Substitution, not deprivation. Coffee at home, cooking instead of takeout, or a cheaper alternative captures most of the savings without going without.
Glossary
- Latte factor
- The idea that small recurring expenses add up to a surprising amount over time, especially when you count the investment growth you give up.
- Opportunity cost
- The value of what you could have done with money (or time) instead — here, the investment returns you forgo by spending.
- Compounding
- Earning returns on your past returns, so invested money grows faster and faster the longer it's left alone.
Frequently asked questions
How much does a daily coffee cost per year?
A $6 daily coffee adds up to about $2,190 a year. The bigger eye-opener is the opportunity cost: if you made coffee at home and invested that $6 a day at a 7% return, you'd have roughly $95,000 after 20 years and over $222,000 after 30 — the famous "latte factor."
How much money can I save by quitting smoking?
At about $8 a pack, a pack-a-day habit costs around $2,920 a year. Quit and invest that money at a 7% return and it could grow to roughly $127,000 over 20 years — on top of the health benefits. Use the calculator with your real pack price, which is much higher in some states.
How much does eating out cost compared to cooking at home?
Dining out three times a week at $20 a meal is about $3,120 a year; even fast food adds up fast at today's prices. Cooking the same meals at home often costs a third as much, and the difference invested over 20 years could be worth well over $100,000.
What is the latte factor?
The "latte factor," coined by author David Bach, is the idea that small daily expenses — a coffee, a snack, a subscription — quietly add up to a fortune over time, especially once you account for what that money could earn if invested instead. This calculator shows your own latte factor for any habit.
