Build a quote that protects the work
A fixed project price should pay for the work you expect, the direct resources the project requires, and the uncertainty you are accepting. It should also leave the margin your business needs to grow.
Start with labor and direct costs
Estimate every stage: discovery, communication, production, revisions, handoff, and administration. Add only costs that belong specifically to this project.
Add a scope and risk buffer
A buffer is useful when requirements are not perfectly predictable. It is not a replacement for a clear scope; it protects against ordinary estimation uncertainty.
Use margin correctly
If you want a 20% margin on the final sale price, dividing the buffered cost by 0.80 gives the correct price. Simply adding 20% produces a smaller true margin.
Example
Forty hours at 75 produces 3,000 in labor. Add 300 of direct costs and a 15% buffer for a 3,795 cost floor. A 20% target margin produces a recommended price of 4,743.75.
Common questions
What profit margin should a freelancer use?
There is no universal margin. Choose one that reflects your operating costs, market, demand, risk, and business goals.
Is a project buffer the same as profit?
No. A buffer covers uncertainty in the estimated cost of doing the work. Profit is what remains after those expected costs.
Should I show clients my hourly calculation?
You can present a fixed price tied to scope and value without revealing the internal calculation.
How much deposit should I request?
Deposits vary with project size, trust, timing, and local practice. State the chosen percentage clearly in the agreement.
