Freelance Project Quote Calculator
A fixed bid puts all the risk on you. Price the hours, a buffer for the unknowns and your expenses — then see what your rate becomes if the job runs long, before you send the number.
Under the hood
The math, fully exposed
We build the quote up from labor, then stress-test the rate against an overrun:
Base labor = estimated hours × hourly rate
Quote = base labor × (1 + buffer %) + expenses
Effective rate = (quote − expenses) ÷ estimated hours
Stressed rate = (quote − expenses) ÷ (hours × 1.25)
- The stressed rate is the real test: if a 25% overrun still clears your floor, the buffer is sized right; if not, you're underbidding the risk.
- Expenses aren't pay: they're stripped out before computing your effective rate, so software and assets don't masquerade as profit.
- Fixed bids reward tight scope: the buffer protects you, but a clear statement of work and billable change requests are what truly contain overruns.

Answers
Frequently asked questions
Why add a complexity buffer to a fixed-bid quote?
Because fixed-price work hides all the risk on your side. The moment you name a single number, every hour beyond your estimate comes out of your own pay. Projects almost always take longer than the optimistic guess — unclear requirements, revisions, integration surprises. A buffer (commonly 15–30%) prices in that uncertainty so a normal overrun does not turn a profitable job into an unpaid one.
How do I know if my quote is actually safe?
Stress-test it against an overrun. This tool shows your effective hourly rate if the project runs 25% longer than estimated — the most useful number on the page. If that "stressed" rate is still above the floor you would accept, your buffer is doing its job. If it drops below your floor, you are one normal delay away from working for less than you would ever agree to hourly.
Should I charge a deposit?
Almost always. A deposit (commonly 30–50% upfront) protects your cash flow, filters out non-serious clients, and means you are never fully exposed if a client disappears mid-project. For larger jobs, milestone payments tied to deliverables are even better. The deposit figure here is a starting point — never begin substantial work on a fixed bid with nothing paid.
Fixed bid or hourly — which should I use?
Hourly protects you when scope is unclear; fixed bid rewards you when you are efficient and the scope is well-defined. Fixed price can be more profitable per hour if you scope tightly and pad sensibly — but only if you control scope creep with a clear statement of work and charge for changes beyond it. This tool is for the fixed-bid case; for setting the underlying rate, use the Freelance Rate Optimizer. Educational model, not financial advice.
