Cut the Big Three: Housing, Transport and Food
Housing, transport and food are most households' largest costs. Why one decision there can beat years of small cuts, with worked examples.
Skipping a daily coffee saves a little. Choosing a home that costs $500 a month less saves $6,000 a year, every year, without another decision. For most households, housing, transport and food are the three biggest costs, and that’s where the real savings are.
The numbers in the worked examples are illustrative.
Why the big three matter most
In the Bureau of Labor Statistics’ latest Consumer Expenditure Survey, for 2025, housing took 33.9% of the average household’s spending, transportation 16.5% and food 13.0%. Together, that’s about 63%. Small savings on big categories add up faster than big efforts on small ones.
Housing
Housing is usually the biggest single cost. The main levers:
- Size and location. A smaller home, or one a little further out, can cost much less.
- Refinancing when rates fall, if the costs of refinancing are covered by the savings.
- Sharing costs, such as renting a room or a separate unit, sometimes called house hacking.
- Running costs: energy efficiency, insurance shopping and property tax appeals.
Worked example: moving to a home that costs $500 a month less saves $6,000 a year.
Transport
Cars are the second big cost for most households, and the true cost is much more than the payment:
- Total cost of ownership includes depreciation, insurance, fuel, maintenance and parking.
- Fewer cars. A two-car household that can manage with one saves the full running cost of a car.
- Older cars. Buying a reliable used car and keeping it longer avoids the steepest years of depreciation.
Worked example: replacing a newer car with a reliable used one, and keeping it for years, might cut $3,000 a year in depreciation and insurance.
Food
Food savings come more from planning than from coupons:
- Plan meals for the week and shop to the plan.
- Cook in batches and use leftovers.
- Eat out deliberately, as a choice, not a default.
Worked example: shifting two takeout meals a week to home cooking might save $2,000 a year for a couple.
Turning savings into a retirement date
Together, the three examples save $11,000 a year. For a household with take-home pay of $90,000 that currently saves $13,500 (15%), saving another $11,000 raises their savings rate to about 27%. Spending drops at the same time, which also lowers the amount they need to retire. Under the assumptions in the savings rate guide, that could bring financial independence forward by more than a decade.
Trade-offs worth respecting
Cheaper isn’t always better:
- A longer commute costs time and wellbeing.
- A smaller home may not suit a growing family.
- An unreliable car can cost more than it saves.
The goal isn’t the cheapest life. It’s spending on what matters to you and cutting what doesn’t. Start by finding your numbers with the spending review.
Common questions
What are the biggest expenses for most households? Housing, transportation and food: about 63% of average household spending in 2025, according to the Bureau of Labor Statistics.
Is it worth moving to save money? It can be, if the savings are large and lasting, and you count moving costs and lifestyle changes.
How much does owning a car really cost? Much more than the payment. Count depreciation, insurance, fuel, maintenance and parking.
How can I cut food spending without coupons? Plan meals, cook in batches, and eat out by choice rather than by default.
