Is it actually cheaper to make it?

Compare the real cost of buying versus making something at home — including batch size, time, supplies, and any equipment you need to buy.

Making it work in real life

Compare hands-on time, not oven or fridge time. Your time matters, but you get to decide how much to value it.
If a batch makes more than you can use, freeze the extra portions so the saving isn’t lost to food waste.

How this calculator works

Store-bought cost per unit is the package price divided by the number of equivalent units. Homemade cash cost per unit is your ingredient and extra batch costs divided by the usable batch yield. Optional time cost uses hands-on minutes and your chosen hourly value, distributed across the usable yield.

Annual estimates use the number of units you said you use each day, week or month. The first-year comparison also includes any equipment you need to buy when you choose to make some of the item yourself. Break-even shows approximately how long it would take for the recurring per-unit advantage to cover equipment costs.

These are planning estimates: the calculation treats units and partial batches proportionally, assumes steady prices and usage, and doesn’t automatically account for sales tax, spoilage of store-bought items, differences in quality, or the value you place on convenience. Example figures are illustrative, so replace them with your local prices.
