Cheap breakfast ideas for Australian households: what actually costs less per serve

Breakfast is worth comparing carefully

Breakfast is the one meal most Australian households eat at home every day, which makes the cost per serve meaningful at a weekly and annual scale. A $0.30 breakfast versus a $2.50 breakfast is a difference of over $800 per year for one person — more for a family.

This guide compares common options on a realistic cost-per-serve basis. Prices vary by brand, retailer and week, so use these as relative comparisons rather than exact figures.

The cheapest options per serve

Rolled oats (porridge): Consistently one of the cheapest breakfasts available. A 1 kg bag of rolled oats from a supermarket makes around 10 serves of porridge. Store-brand oats cost less per 100 g than name brands and are nutritionally equivalent. Add frozen berries or banana for variety without much extra cost.

Eggs on toast: Eggs are cheap per serve, especially when bought in larger cartons. Two eggs on a slice of store-brand toast with butter is a filling, low-cost breakfast. The cost per serve is modest and the meal requires no advance preparation.

Toast with peanut butter or vegemite: The cheapest hot breakfast option for most households. Store-brand bread and a jar of peanut butter or vegemite spread the cost very thinly per serve. A 375 g jar of peanut butter covers many breakfasts.

Mid-range options

Yoghurt with fruit or muesli: A large tub of plain or Greek yoghurt from a supermarket costs significantly less per 100 g than individual-serve cups. Buying a 1 kg tub and serving it in a bowl with fruit or a small amount of muesli is a reasonable cost. Avoid individual flavoured yoghurt cups — they are among the most expensive per-gram options in the dairy aisle.

Weet-Bix and similar whole-grain biscuits: Mid-range in cost but a large box goes a long way. Store-brand wheat biscuits are generally cheaper than Weet-Bix and nutritionally very similar.

Where the cost climbs quickly

Branded boxed cereals: Name-brand cereals are expensive per 100 g and per serve compared with oats or wheat biscuits. Portion sizes listed on the box are also often smaller than what most people actually eat. Store-brand versions of popular cereals close much of the gap.

Muesli: Pre-made muesli — especially "natural" or "toasted" varieties from name brands — is expensive per 100 g. Buying rolled oats and adding your own dried fruit and nuts is substantially cheaper if you eat muesli regularly.

Smoothie pouches and breakfast drinks: Convenient but expensive per serve and not particularly filling compared with whole food alternatives.

Comparing cereal and breakfast staple prices

Breakfast staples like oats, cereal and yoghurt have consistent SKU names and pack sizes across retailers — making them straightforward to compare. Run a search on TrolleyChecker for your regular brands before a restock, and check whether store-brand alternatives are worth trying at your usual chain.
