Everything is calculated in your browser: the prices and numbers you enter are never sent anywhere or stored. We do not know any store's prices or tax rates, and these results are arithmetic, not advice to buy.

Assumptions

  • Each step is rounded to the cent once.
  • This adds up what you enter. It does not suggest stocking up: buying more than you will use costs money and space.

Printed from oneclickanswers.com. Results are estimates based on what was entered; see the assumptions above.

How it works

Subtotal = packages x price: 6 x $4.99 = $29.94. A 10% discount takes off $2.99, leaving $26.95; 7% tax adds $1.89, for $28.84.

With 24 units a package, that is 144 units at about 20.0 cents each.

Assumptions

  • Each step is rounded to the cent once.
  • This adds up what you enter. It does not suggest stocking up: buying more than you will use costs money and space.

Example

Input: The starting values already in the form

Result: Stocking up on 6 packages would cost $28.84, or about 0.2 per unit for 144 units.

Questions

Does it work out the tax?

It uses the rate you enter. It does not look up a rate.

The total divided by all the units in all the packages.
