Project Profitability Calculator

Estimate whether a project is profitable by comparing revenue, direct costs, overhead allocation and contingency costs.

Your Details

Overview

A project profitability calculator helps you estimate whether a job, contract or internal project is worth taking on. Enter your expected revenue, direct costs, allocated overhead, contingency percentage and any extra project income to see the likely profit and margin.

How it works

The calculator adds your direct costs and allocated overhead to get a base cost. It then applies the contingency percentage to estimate additional risk-related cost. Total revenue is your main project revenue plus any extra project income. Estimated profit is total revenue minus total cost, while profit margin shows profit as a percentage of revenue and return on cost shows profit relative to cost.

How to use this calculator

  1. 1Enter the total revenue you expect from the project.
  2. 2Add all direct project costs such as labor, materials and subcontractors.
  3. 3Include the overhead amount you want to allocate to this project.
  4. 4Set a contingency percentage for unexpected costs.
  5. 5Add any other project-related income and review the estimated profit and margin.

Example Calculation

Project revenue

$25,000

Direct costs

$14,000

Allocated overhead

$3,000

Contingency

5%

Other project income

$500

Estimated profit

$7,650

With project revenue of $25,000, other income of $500, direct costs of $14,000, overhead of $3,000 and a 5% contingency, the estimated total cost is $17,850 and the projected profit is $7,650, which is about a 30.0% margin.

Frequently asked questions

What does this calculator estimate?

It estimates total project cost, expected profit, profit margin and return on cost based on the figures you enter.

What should be included in direct costs?

Direct costs usually include labor, materials, equipment, subcontractors, travel and other expenses directly tied to delivering the project.

What is allocated overhead?

Allocated overhead is the share of general business costs, such as rent, admin, software or insurance, assigned to the project.

Why use a contingency percentage?

A contingency helps account for uncertainty, scope changes, rework or unexpected expenses that may increase project cost.

What is the difference between profit margin and return on cost?

Profit margin compares profit with revenue, while return on cost compares profit with the total cost of the project.

Can this calculator be used for fixed-price projects?

Yes. It is especially useful for fixed-price work where you need to check whether the quoted revenue covers expected costs and target profit.
