For example, a product costs $25 and there is discount of 6% or $1.50 giving the discounted price of $23.50.

If I didn't know the Gross price, what is the formula to get it from the discount% and the net?

Since $23.50 is the 94% discount price (the 6% off price), if you divide the price by 96 (to get the 1% price) and multiply by 100 you will arrive at the full price. I assume that is what you're looking for.

I would divide the amount of the discount ($1.50) by the percentage (.06).

1.50 / .06 = 25

I would do 25 * 0.94 (the opposite of 6%) = 23.50

x'cept he said he doesn't know the 'list' price of $25.

Oh yes, I see.

I would divide the amount of the discount ($1.50) by the percentage (.06).

In that case, he also doesn't know the amount of the discount! ;)


In that case, just do it the other way around:

$23.50 / 0.94 (opposite of 6% ) = $25

I was responding to what Bo Janges said he knew when he asked his question :)

No, you missed the point like I did.

He only knows the $23.50 and the 6%. He was just stating the full $25 as in this example he knew what that was. Without that you don't know the discount is 1.50.

What is "gross price"?

If there is 6% off, you don't add 6 % to the discounted price to get to the full price.

Think about it.

33% off of 3 is 2, for sure.

33% on top of 2 is only 2.66 - you will need to add 50% on to get back to 3.

You need the reciprocal for the reverse calculation.

.

In this question, the 6% refers to the unknown price, not the one that is known.

The sum of the square roots of any sides of an isoscelese triangle is equal to the square root of the remaining side.

The unknown price is X
The discount is 6% (.94)
The net price is 23.50

X x .94 = 23.50

Divide each side by .94

X = 25

33% off of 3 is 2, for sure

Or 50% extra free!

Say you have 3 items, each costs £1.

£3 * 0.666.... (opposite of 33%) = £2 (almost).

But to go the other way you do

£2 / 0.666.... = £3

The thing that changes is the sign, one is *, one is /.

No, you missed the point like I did.

Dabrowski, yes, you are right ... I did miss the information: that the OP only had "the discount% and the net" to work with ...

So it is, then, a simple calculation of 6% of X = 23.50
and your (posted) calculation is, of course, correct.

Whew ... :-¦

(I can't help but wonder if the OP (Mr Bo Jangles) got the accurate information before he went off to "finish his project" ;-d

OK, I have a similar question - how do you calculate an increase (or decrease) in terms of percentage?

For example, let's say somehitng costs $15 and then the price goes up to $20....

Is that a 25% increase: 100% * (1 - 15/20)?

or is it a 33.33% increase: 100% * (20/15 - 1)?

or is it a 33.33% increase

Yes, $20.00 is a 33.33% increase from $15.00.

Expressed in a different context, if you wanted to get a 25% margin on a $15.00 item, you would want a "mark up" of 33.33%.

tim222, It is fairly easy to fiqure out that 5 is 33.3% of 15. However here is how you calculate the increase for more difficult numbers.

The new price minus the original price will give you the difference. Then you divide the difference by the original price to get the percentage of increase.

20 - 15 = 5

5 divided by 15 = .33333 (or 33.3%)

Ah thanks. I wasn't sure which number to use.

Bah! That's far too long winded!

There's 2 ways you can calculate percentages in this case:

15 (original) / 20 (new) = 0.75 (75%)

That shows that the original is 75% of the new.

20 (new) / 15 (original) = 1.333... (133%)

Shows that the new is 133% of the original, or a 33% increase.

Any more?
