On 22 October 2026, Katoomba Ingredients Yellow Split Peas 1kg (dry) at Woolworths: about $1.00 per 100 g of protein (98.8 g protein per $1).
How much does 100 g of protein usually cost?
Across the 519 products we track, the middle (median) cost is $12.20 per 100 g of protein. The cheapest products on this page cost a fraction of that.
What's the cheapest protein at each supermarket?
ALDI: Oh So Natural Red Split Lentils 500g (dry) (70.4 g per $1); Coles: Coles Red Split Lentils (dry) (57.5 g per $1); Woolworths: Katoomba Ingredients Yellow Split Peas 1kg (dry) (98.8 g per $1).
How is cost per gram of protein worked out?
Shelf price divided by the grams of protein in the pack, from the pack's own nutrition panel. Tinned fish uses the drained weight and eggs use the edible portion, so you only pay for what you eat.
Is the cheapest protein per gram the best choice?
Not always. Dry lentils and beans are cheapest per gram but come with more calories and carbohydrate than lean meat, fish or high-protein yoghurt. Check protein per 100 kcal too.
