Why quote a fixed price?

Clients like fixed prices because they know exactly what they will pay. Freelancers like them because a fast, experienced worker is not punished for working quickly. The risk is underestimating: projects almost always take longer than the first guess, thanks to extra revision rounds, slow feedback and small requests that pile up. A fixed quote only works if it includes room for that.

This calculator starts from your hourly rate and your honest estimate of the hours, adds a scope buffer on top, then adds any costs you will pay for the project. It also splits the price into a deposit and a final payment, which protects you if a client disappears halfway through.

The formula

Hours with buffer = estimated hours × (1 + buffer %)
Labor = hours with buffer × hourly rate
Quote = labor + project expenses
Deposit = quote × deposit %

Worked example

You charge $75 an hour and expect a website design to take 40 hours. With a 20% buffer that becomes 48 hours, or $3,600 of labor. Add $100 for a premium font licence and the quote is $3,700. With a 50% deposit, the client pays $1,850 to start and $1,850 on delivery.

Tips for better quotes

Break the project into tasks and estimate each one. Small estimates added together are more accurate than one big guess.
Use a bigger buffer for new clients or unclear briefs. 10–15% suits repeat work you know well; 25–30% suits anything new.
Write down what is included, such as the number of revision rounds. Extra work outside that list is billed separately.
Round to a clean number. $3,700 reads better in a proposal than $3,687.50.

Frequently asked questions

How big should my scope buffer be?

Many freelancers add 10% to 30%. Look at past projects: if they usually ran 25% over your estimate, use at least 25%.

Is a 50% deposit normal?

For small and mid-sized projects, 30% to 50% upfront is common. Large projects are often split into several milestone payments instead.

Should I show the client my hourly breakdown?

You do not have to. Many freelancers share the scope and the total price only, so the conversation stays about results rather than hours.
