Percentage Profit Calculator

When it comes to calculating price per unit of their purchases, many grocery shoppers don’t bother. Maybe they think the savings are too small to matter or maybe they’re intimidated by the math. But calculating what you pay per ounce isn’t hard to do, and it can mean substantial savings on groceries and other household necessities.

How to Calculate Price per Ounce

The formula is simple: take the dollar amount of the product and divide it by the number of ounces in the package.

For example, if a 42-ounce canister of oats costs $4.39 at the grocery store then you will be paying 10.4 cents an ounce.
