Freelance Quote Calculator

Estimate a freelance project quote based on your hourly rate, time, expenses, buffer and profit margin.

Your Details

Overview

This freelance quote calculator helps you estimate what to charge for a project using your hourly rate, expected hours, extra expenses, a contingency buffer and a profit margin. It is useful for building quick project prices that are more structured than guessing a flat fee.

How it works

The calculator starts by multiplying your hourly rate by the estimated hours to get your labour cost. It then adds any direct expenses to create a base project cost. A contingency buffer is applied as a percentage of that base cost, and then a profit margin is added on top of the buffered subtotal. The result is an estimated project quote, along with an effective hourly rate based on the final quoted amount.

  2. 2Add the number of hours you expect the work to take.
  3. 3Include any direct project expenses.
  4. 4Set a contingency buffer for revisions or unknowns.
  5. 5Add a profit margin and review the estimated quote.

Frequently asked questions

What does this freelance quote calculator estimate?

It estimates a project quote using your hourly rate, expected project hours, direct expenses, contingency buffer and profit margin.

Should I include revisions in my estimated hours or in the buffer?

You can do either, but many freelancers include expected revisions in the hours and use the buffer for uncertainty or small scope changes.

What are additional expenses?

Additional expenses are direct project costs such as stock images, travel, specialist tools, printing or subcontractor fees.

Why add a profit margin if I already have an hourly rate?

A profit margin can help cover business growth, risk and non-billable time beyond the direct cost of delivering the project.

Can I use this calculator for fixed-price projects?

Yes. It is especially useful for building a fixed project quote from time estimates and project-specific costs.

Does this calculator include tax?

No. The estimate does not automatically include sales tax, VAT or other taxes unless you include them in your rate or expenses.
