You have probably heard someone say, "Just stop buying coffee and you'll be rich." It sounds dismissive — and on its own, it kind of is. But the core idea is worth taking seriously. The Latte Factor, a concept popularised by American financial author David Bach, is not really about coffee at all. It is about recognising how small, seemingly insignificant daily expenses quietly compound into large sums over time.
In his book The Latte Factor, Bach argues that most people already earn enough to build wealth — they just do not realise where their money is going. The trick is not earning more; it is keeping more of what you already earn and letting compound interest do the heavy lifting.
What Exactly Is the Latte Factor?
The Latte Factor is any small, recurring expense you could reduce or eliminate without significantly affecting your quality of life. Bach named it after the daily latte habit, but it extends to anything you spend money on out of routine rather than genuine need or deep enjoyment.
Think of it as a lens for examining your spending. It is not about deprivation — it is about awareness. Once you see where the money is trickling away, you can make deliberate choices about what stays and what goes.
The Maths: $5 a Day Becomes How Much?
A daily $5 coffee habit costs $35 a week, or roughly $1,825 a year. Not life-changing on its own. But stretch that out over a decade or two with compound returns and the number gets uncomfortable.
After 10 years: $26,400
After 20 years: $78,800
After 30 years: $185,400
That single daily coffee could cost you nearly $200,000 in potential wealth over a career.
Now scale that up. Many people do not just buy a coffee — they grab a muffin, a juice, or a snack too. What about the daily takeaway lunch?
After 10 years: $95,000
After 20 years: $283,800
After 30 years: $667,400
Bringing lunch from home even three or four days a week could redirect hundreds of thousands of dollars towards your future.

Common "Latte Factors" Most People Miss
Coffee is the famous example, but most people have several latte factors hiding in their budget. Here are the most common ones:
- Bought lunches and snacks: Even at $12-18 per day, this adds up to $3,000-4,700 a year.
- Unused or underused subscriptions: Streaming services, gym memberships, apps, and software you barely touch. The average Australian household has over $100 per month in subscriptions. See our guide on whether your subscriptions are wasting money.
- Convenience fees: ATM surcharges, delivery fees, express shipping, and "click and collect" add-ons.
- Impulse buys: That $15 item at the checkout, the on-sale gadget you never use, the extra item thrown into an online cart to get free shipping.
- Premium upgrades you do not need: The large coffee when a regular would do, premium fuel for a car that does not require it, brand-name items when generics are identical.
- Bottled water: At $3-4 a bottle, buying water daily can cost over $1,000 a year when a reusable bottle costs $20 once.
- Parking and transport extras: Paying for parking when a short walk from a free spot would do, or catching an Uber for a trip you could easily walk or cycle.

How to Find Your Personal Latte Factor
Finding your latte factor is straightforward, but it requires honesty. Here is a simple three-step process:
Step 1: Track Everything for Two Weeks
Write down every single purchase you make — no matter how small. Use a notes app, a spreadsheet, or a dedicated expense tracker. The key is capturing everything, especially the small stuff you normally forget about.
Step 2: Categorise and Add It Up
At the end of two weeks, group your spending into categories: coffee, snacks, lunches, transport, entertainment, subscriptions, and so on. Multiply each fortnightly total by 26 to see the annual figure. You will likely be surprised by at least one category.
Step 3: Ask the Hard Question
For each category, ask yourself: "Does this spending genuinely make my life better, or is it just a habit?" Be honest. Some spending is absolutely worth it — perhaps that morning coffee is your favourite ritual and you would never give it up. That is fine. The goal is to find the spending that does not bring you proportional joy.
What to Do With the Savings
Identifying your latte factor is only half the equation. The other half is redirecting that money somewhere it actually grows. Here are the best options:
- Pay down debt: If you have a mortgage, even small extra repayments can save you thousands in interest over the life of the loan.
- Build an emergency fund: If you do not have three to six months of expenses saved, that should be your first target. Our emergency fund guide walks you through it step by step.
- Invest for the future: Once your safety net is in place, investing your latte factor savings into an index fund or superannuation can harness the full power of compound interest.
- Automate it: Set up an automatic transfer for the amount you are saving. If you are cutting $5 a day, schedule a $35 weekly transfer to a separate high-yield savings account. You will not miss what you do not see.
The Latte Factor Is Not About Deprivation
The biggest criticism of the Latte Factor is that it feels like penny-pinching — like you are being told you cannot enjoy anything. That is a misunderstanding of the concept.
The Latte Factor is about mindful spending. It is about making sure your money goes towards things you genuinely value, rather than leaking away on autopilot purchases. If your daily coffee brings you real joy, keep it. But be honest about which expenses are habits and which are choices.
Your latte factor is the gap between where your money goes and where you want it to go. Closing that gap does not require earning more — it just requires noticing.
