Cost Breakdown Analysis Calculator

Work out cost breakdown analysis instantly with clear inputs, formula shown and shareable results.

About Cost Breakdown Analysis Calculator

A cost breakdown request lets you compute the implied margin and test whether the declared structure is plausible. A high material share limits how much negotiation can achieve on labour and overhead, and points instead to design change or joint sourcing of raw material.

Formulas

Declared cost

Declared cost = Material + Labour + Overhead

Implied margin

Implied margin % = (Quoted price - Declared cost) / Quoted price x 100

Worked example

With the default values below, Cost Breakdown Analysis Calculator returns Implied supplier margin of 13.95%. Change any input above and every figure here is recalculated in your browser.

Inputs used

Quoted price: 8,600
Declared material cost: 4,100
Declared labour cost: 1,800
Declared overhead cost: 1,500

Results

Implied supplier margin: 13.95%
Implied margin value: $1,200.00
Material as % of price: 47.67%
Conversion cost as % of price: 38.37%

Assumptions and limits

The result is derived only from the 4 inputs listed above. Anything not among them is not part of the calculation.
In particular, this calculator does not take inflation, tax or compounding frequency into account.
Figures are rounded for display to 2 decimal places, so totals built from several rounded parts can differ slightly from the unrounded arithmetic.

How these calculators are built and tested is described on the Methodology page. If a figure looks wrong, please report it.

Frequently Asked Questions

Will suppliers provide a breakdown?

Often in a long-term relationship or where it is a tender condition. Open-book arrangements make it contractual.

What if the material share is very high?

Negotiation on price will achieve little. Focus on specification change, alternative materials, or buying the raw material yourself and free-issuing it.
