The price variance formula
(invoice unit price − PO unit price) × invoice quantity = total price variance
A positive result means the invoice is above the PO price. A negative result means it is below. This calculator does not decide whether the difference is acceptable; compare the result with the tolerance and contract terms your business uses.
What to check before approval
| Check | Why it matters | Evidence to retain |
|---|---|---|
| Unit basis | A case price and an each price can look like a large variance while describing the same economics. | PO and invoice unit-of-measure fields. |
| Currency | Amounts in different currencies should never be compared as if they share a unit. | Currency code and agreed exchange treatment. |
| Credits and fees | Freight, rebates, and credits may belong on separate lines rather than changing item cost. | Invoice line description and PO terms. |
| Tolerance | A tolerance should be explicit and consistently applied, not inferred after seeing a variance. | Dollar or percentage policy used for review. |
