% Not Calculating Correctly

I created a coupon for 15% and it is calculating a 16.31 % Discount at check out... any idea why it is doing this?

Thank you

Hello Philip,

Not sure, would need more information to figure out why:

- what version of virtuemart are you using
- moving from the normal shopping cart page all the way through confirmation page, does the discount stay the same?
- what is your tax rate?
- what tax mode are you using?
- are you displaying prices with tax?
- can you provide the numbers of the example above where you receive 16.31%? subtotal, total, shipping, tax,.... every number on the screen

- what version of virtuemart are you using

VERSION 1.1.2

- moving from the normal shopping cart page all the way through confirmation page, does the discount stay the same?

Yes it does stay the same all the way through.

- what is your tax rate?

Tax for California 0.0875/ Nevada 0.0810

- what tax mode are you using?

Based on shipping address

- are you displaying prices with tax?

No

- can you provide the numbers of the example above where you receive 16.31%? subtotal, total, shipping, tax,.... every number on the screen

Subtotal: $149.70
Shipping and Handling Fee: $13.65
Tax Total: $13.10
Coupon Discount: - $24.42

Total: $152.03

the coupon discount is displayed with tax:

149.7*1.0875 = 162.80 (product total with tax)
162.8*0.15 = 24.42 (coupon discount with tax)
162.80 - 24.42 = 138.38 (product total with tax after discount)

---------------------------------

149.7 (product total without tax)
149.7*0.15 = 22.455 (coupon discount without tax)
149.7-22.455=127.245 (product total without tax after discount)
127.245*1.0875 = 138.38 (product total with tax after discount)

Either way. the total ends up the same.

Thank You
