How do you calculate ABC inventory value?

Multiply annual units consumed by unit cost for the annual usage value; the capture share and carrying adder are shown as context rows. With 100 units at $45: $4,500 of annual usage value.

What is the 80/20 rule in ABC analysis?

A-items are the top ~20% of SKUs that account for ~80% of inventory dollar value, B-items the next ~30% covering ~15%, and C-items the remaining ~50% covering ~5%. Value rank, not part count, drives the class.

What does the capture factor represent?

It shows the share of the value you choose to weight, for example the fraction of annual usage held in inventory at once; in the example the 80% capture row reads $3,600 against the $4,500 headline.

Why add a fixed adder?

The fixed carrying adder captures per-SKU costs that don't scale with volume, such as setup, handling, or minimum storage charges. It is reported beside the usage value rather than mixed into it.

What is a good ABC split?

There is no universal number, but a healthy catalog often shows A-items as 15-25% of SKUs and 70-80% of value. If your A-class holds far more than a quarter of your part numbers, your thresholds are set too loosely.

ABC analysis vs. XYZ analysis?

ABC ranks SKUs by dollar value; XYZ ranks them by demand variability. Combining them (AX, CZ, etc.) tells you both how much a part costs and how predictable it is, which sharpens safety-stock decisions.

Supply Chain & Procurement calculator

ABC Inventory Value Calculator

ABC inventory value is the annual dollar consumption of a SKU, used to sort a catalog into A-items (the vital few that tie up most of the money), B-items, and C-items (the trivial many) under Pareto's 80/20 principle. Purchasing managers, inventory planners, and materials controllers use it to decide where to invest control effort, which parts get tight cycle counts and safety stock, and which get loose reorder rules. It matters because roughly 20% of SKUs typically drive 80% of inventory investment, and treating every part equally wastes both cash and attention. This tool computes a weighted annual value so you can rank and classify.

What this calculator does

Estimate ABC inventory value from item count and average value.
Use it when abc inventory value in supply chain and procurement is being put through a supply chain and procurement weighted-cost review.
It computes a SKU's weighted annual inventory value from usage times unit cost times a capture factor, plus any fixed carrying adder.

Formula used

Annual usage value = annual units consumed × unit cost

Inputs explained

Annual units consumed:
Unit cost:
Value capture factor:
Fixed carrying adder:

How to use the result

Use it when building or refreshing an ABC classification, prioritizing safety-stock investment, or setting cycle-count frequency by dollar velocity.
Annual dollar value alone ignores criticality, a cheap C-item that halts a line when stocked out may deserve A-item treatment regardless of its value rank.

Importers paid an average effective tariff of 12.4% of customs value in 2025 across the 57 manufacturing import families MFG Calcs tracks (USITC DataWeb), up from 3.3% the year before. Statutory and effective rates by family, with top source countries, are at mfgcalcs.com/tariffs.
