So for this example we have the following items with cost:
Item ID | Amount |
---|---|
ROGGVIN-SAMPLER | 24.85 |
ROGGN-2.1OZ-EA | 6.95 |
ROGGNP-2.2OZ-EAU | 4.95 |
The subtotal for the order was 36.75 and there were subtotal discounts of 7.95. So if we look at the % allocations it would be:
Item ID | Math | Percentage |
---|---|---|
ROGGVIN-SAMPLER | 24.85 / 36.75 | 67.62% |
ROGGN-2.1OZ-EA | 6.95 / 36.75 | 18.91% |
ROGGNP-2.2OZ-EAU | 4.95 / 36.75 | 13.47% |
Taking those allocation percentages we have the following subtotal discount portions:
Item ID | Math | Portion of Subtotal Discount |
---|---|---|
ROGGVIN-SAMPLER | 7.95 * 67.62% | 5.37 |
ROGGN-2.1OZ-EA | 7.95 * 18.91% | 1.50 |
ROGGNP-2.2OZ-EAU | 7.95 * 13.47% | 1.07 |
Subtracting the portion of the subtotal discount from the original item unit prices we get
Item ID | Math | Effective Unit Price |
---|---|---|
ROGGVIN-SAMPLER | 24.85 - 5.37 | 19.48 |
ROGGN-2.1OZ-EA | 6.95 - 1.50 | 5.45 |
ROGGNP-2.2OZ-EAU | 4.95 - 1.07 | 3.88 |
