Grocery budgeting for couples in Australia

Two people, one grocery budget

Couples and two-person households face a specific grocery challenge: supermarket packaging, recipes and promotions are often sized for four or more people. Buying in formats suited to a larger household leads to food waste, while buying in smaller formats costs more per unit. Getting the grocery routine right for two people takes a bit of adjustment from either a single-person or larger household pattern.

How much should two people spend on groceries?

A rough guide for two adults in Australia is $150 to $250 per week for a full shop covering all meals. This varies depending on dietary preferences, how often you eat out, whether you buy alcohol and the cost of living in your area.

If your current spend is above this, it is usually because of one or more of the following: regular takeaway or delivery, premium branded products, significant food waste, or buying more fresh produce than you use.

Right-sizing portions and packs

Many households of two buy in quantities suited to four and discard the surplus. The fix is deliberate right-sizing:

• Meat: Buy the portion you need rather than the cheapest bulk pack you cannot use. A full chicken can serve two people across two meals — roasted for one dinner, then used in a salad, sandwich or pasta the next day. Buying a whole chicken this way is cheaper per serve than buying pre-cut chicken fillets.
• Vegetables: Buy loose vegetables rather than bagged where possible. Two zucchinis rather than a bag of six. One head of broccoli rather than a twin-pack.
• Bread: A standard 700 g loaf often goes stale for two people who do not eat much bread. A smaller loaf, or freezing half immediately, prevents waste.

Batch cooking for two

Batch cooking works well for couples with a slight adjustment: cook four to six serves rather than two, and store the surplus for next-day lunches or mid-week dinners. A large pot of soup, a casserole or a curry made on Sunday provides two dinners and two lunches across the week, significantly reducing per-meal cost. Our meal planning guide covers building this into a weekly routine.

Managing two different preferences

Couples with different dietary preferences face a common challenge — cooking separate meals is time-consuming and expensive. Strategies that work well:

• Build meals around a shared base (grain, roasted vegetables, pasta) with different proteins or toppings.
• Identify the overlap in preferences and plan the week's meals from there.
• Designate one or two nights per week where each person cooks or eats what they prefer independently — this contains the variable rather than making every meal a negotiation.

Avoiding over-buying

Two-for-one and multi-buy promotions are designed for larger households. For a couple, a two-for-one deal on a perishable product only saves money if you will genuinely use both before they expire. When in doubt, buy one at the full price and avoid the waste.

Comparing the regular shop

For packaged goods that both people use regularly — coffee, breakfast items, sauces, condiments — running a quick price check on TrolleyChecker before a restock ensures you are buying from whichever chain has the better price this week rather than defaulting to habit.
