Landed Material Cost Calculator: Compare Cost per Usable Unit
Use one consistent unit. This focused purchase comparison does not determine GST eligibility or full inventory valuation. Investigate abnormal losses separately.
Use your own assumptions. Inputs stay on your device and are not submitted or saved. Checked: October 2026.
Calculation basis
Comparison cost = supplier amount − confirmed discount + freight + reviewed non-recoverable taxes + other direct acquisition costs. Unit cost = comparison cost ÷ usable quantity.
