Make or Buy Decision

Make or Buy Decision Meaning

A Make or Buy Decision is a decision made to either manufacture a product/ service in house or buy it from outside suppliers (outsourcing) based on cost-benefit analysis. A complete or accept decision can be made using quantitative or qualitative research and most of the time, the results of quantitative analysis (cost-benefit analysis) are enough to decide on whether to make the product in-house or buy (outsource) from outside suppliers.

How Does Make or Buy Decision Work?

The decision applies to both goods and services. Businesses compare the cost and benefits of producing the goods or services within the company and the cost and benefits of getting an outside supplier to supply the goods and services into consideration. The value here must include all the fees associated with manufacturing (including material, labor, cost of machinery and space), storing, moving, taxes, etc. and the corresponding benefits must include benefits in terms of increased margins (for in-house production) or low capital requirement (for outsourcing).

Make or Buy Decision Example #1

As stated earlier, there may be some factors at play that may influence a company’s company’s decision to make an item in the house or outsourcing it.

Under such circumstances, two factors are to be considered:

  1. Whether surplus capacity is available and
  2. The marginal cost of per unit manufacturing

Assume a company is deciding between manufacturing a part in-house that costs $26 per unit, including direct cost, fixed overheads, and variable overheads, as given in the table below.

Cost HeadCost per Unit ($)
Direct Cost15
Fixed Overhead4
Variable Overhead7
Total Cost26

The same part is available in the market at $23 per unit, including the cost of buying, shipping, and warehousing, as shown in the table below.

Cost HeadCost Per Unit ($)
Cost of Part20
Shipping and Warehousing Cost3
Total Cost23

Should the Firm Make or Buy the part?


If surplus capacity available will remain idle if the component is bought, out of pocket expensesOut Of Pocket ExpensesOut-of-pocket expenses are the expenses that an employee pays out of their own pocket and then gets reimbursed from their employer. Transportation, meals, and lodging expenses are common more will be $23 per unit, $1 more than the variable and direct cost of making component which is $22 ($15 + $7). Hence it is economical to make it. However, if the Firm is utilizing or can utilize the capacity in making some other part which contributes to say $4 per unit in profits, the effective cost of buying the component will be $19 ($23 less $4 contribution from other products). In that case, it would be economical to buy the Component at $23 per unit from outside.

The relevant calculation for making decision may be as follows:
