Frequently Asked Questions

How many cups does a standard granola batch make?
A typical home batch — 4 cups of oats plus the supporting ingredients — yields approximately 6 cups of finished granola. The oats lose a little volume during toasting but the nuts, seeds, and dried fruit added afterward bring the total back up. Your batch size scales linearly, so doubling every ingredient doubles your yield.
Why does store-bought granola cost so much more per cup?
Premium granola brands price in marketing, packaging, retail markup, and often specialty ingredients like organic oats or exotic nuts. The ingredient cost itself is only a fraction of the retail price. When you buy in bulk and make your own, you pay only for the ingredients — which is why the savings can reach 50 to 70 percent compared to name brands.
What is the cheapest way to make homemade granola?
Use old-fashioned rolled oats from a bulk bin or large bag, choose sunflower seeds or pumpkin seeds instead of almonds or cashews, sweeten with plain honey or brown sugar, and skip expensive add-ins like coconut flakes or cacao nibs. Raisins are the most economical dried fruit. With those substitutions, many batches come in under $0.50 per cup.
How long does homemade granola stay fresh?
Stored in an airtight container at room temperature, homemade granola stays fresh for 2 to 3 weeks. In the refrigerator it lasts up to 6 weeks, and it can be frozen for up to 3 months. Make sure it has cooled completely before sealing the container — trapping steam causes it to lose its crunch quickly.
Does this calculator account for energy costs like oven use?
The calculator focuses on ingredient costs, which make up the large majority of the total. Baking a granola batch for 25 to 30 minutes at 325°F typically costs $0.05 to $0.15 in electricity, depending on your utility rate — a small addition that does not change the savings picture meaningfully for most households.

Is Homemade Granola Actually Cheaper Than Store-Bought?

Premium granola brands routinely sell for $8 to $14 per pound at grocery stores, yet the core ingredients — rolled oats, nuts, honey, and a splash of oil — cost a fraction of that per serving. Making granola at home is one of the fastest ways to cut your breakfast budget without giving anything up in taste or nutrition.

A standard batch uses about 4 cups of rolled oats, 1 cup of mixed nuts or seeds, a third cup of sweetener (honey or maple syrup), a quarter cup of oil, and half a cup of dried fruit. That combination typically yields around 6 cups of finished granola. Depending on where you shop and which ingredients you choose, the per-cup cost for homemade granola often lands between $0.50 and $1.00 — compared to $1.75 to $3.50 per cup for premium store brands.

The biggest lever is your nut and seed choice. Almonds and cashews push the cost up; sunflower seeds and pumpkin seeds keep it low. Buying oats in bulk (5 lb bags) cuts that line item nearly in half. Sweetener type has a smaller impact than most people expect because you use relatively little of it per batch.

Beyond cost, homemade granola gives you full control over sugar content, fat levels, and ingredient quality. Most commercial granolas are higher in added sugar and oil than they appear on the label — a homemade batch lets you dial both down without sacrificing the crunch.
