Bulk Savings Calculator

Find out whether the larger package saves money before it goes stale.

Buying bigger is usually cheaper per ounce — but a 5 lb bag of a spice you use a teaspoon of each month is money thrown away. This calculator weighs the per-unit saving against how long the bigger pack will last you.

Enter the small and large package, your weekly usage and the product's typical shelf life. You get the saving per unit, the saving over the life of the pack and a clear verdict.

The large pack saves $10.97 and you will finish it in about 16 weeks — well within its shelf life.

How it works

  1. Both packages are converted to a common unit and their unit prices compared.
  2. Your weekly usage tells us how many weeks the large package lasts; if that is longer than the shelf life, the part you would throw away is subtracted from the saving.
  3. The verdict compares what you would spend buying the small package repeatedly for the same period against the large package, including any waste.

Worked example: turmeric powder

4 oz at $6.49 ($1.62/oz) versus 16 oz at $14.99 ($0.94/oz). At 1 oz a week the 16 oz bag lasts 16 weeks — well inside a 52-week shelf life — and buying four 4 oz bags over the same period would cost $25.96, so the big bag saves $10.97. At 0.25 oz a week the bag lasts 64 weeks, so about 3 oz would be past its best, and the saving shrinks to a few dollars.

Bulk Savings Calculator — questions

How long do spices keep?

Whole spices keep their aroma for two to three years when stored cool, dark and sealed; ground spices and leaf powders for about a year. Our storage guide covers this in detail.

What does 'weekly usage' mean?

The amount you actually use in a typical week, in the same unit as the package. If you are unsure, think about how long your current small package lasts and divide.

What if I don't know the shelf life?

Leave the default (52 weeks for ground spices). Dry pantry goods, coffee and cleaning supplies all have different windows; the product label or manufacturer's site is the authority.

Does this include shipping?

No. Enter the price you actually pay, including shipping or tax if you want them reflected.

Can I use it for non-food products?

Yes — laundry pods, pet food, batteries, anything sold in sizes. Set the shelf life to something long for products that do not expire.

Why do you ask about waste?

Because a 'saving' on a package you only half use is not a saving. Counting likely waste gives a truer answer than unit price alone.

Where do the suggested bulk packs come from?

From the partner-brand catalog sold by MyShopperBuddy: products available in both a small and a large size, with the real per-ounce saving between them.
