Freelance Project Price Estimator
Not sure how much to charge for a freelance project? This free how-much-to-charge-for-a-freelance-project calculator turns your hourly rate and hour estimate into a fixed project price — adding a buffer for scope creep and any extra expenses, plus your effective hourly and day rates so you can quote with confidence.

How to use this calculator
Enter your hourly rate — what you'd happily earn per working hour — and your best estimate of the hours the project will take, including meetings, revisions, and admin. Then set a buffer percentage for scope creep (25% is the default and a common starting point) and add any extra expenses you'll pay out of pocket, like stock assets, travel, or subcontractors.
The calculator updates instantly as you type: the big number is the project price to put on your quote, with a breakdown of base cost, buffer amount, and expenses underneath. You can also press Calculate to recompute on demand.
Check the day-rate equivalent as a sanity check — if the per-day figure is far above or below what your market pays, revisit your hourly rate before sending the proposal.
How it works
The project price is: price = hourly rate × estimated hours × (1 + buffer ÷ 100) + expenses. The buffer is applied only to your labor — your time risk — and expenses are added afterward at full cost, since padding third-party costs would overcharge the client.
Two extra figures help you judge the quote. The effective hourly rate is price ÷ hours: what you're really earning per hour once the buffer and expenses are folded in. The day-rate equivalent is price ÷ (hours ÷ 8), i.e. the project price expressed as a per-day rate assuming 8-hour days, so you can compare it with day-rate benchmarks in your field.
This is an estimate to guide your pricing, not financial advice. It can't see your market, taxes, or how much you underestimate your own hours — the most common reason freelancers undercharge. Use it as the starting point for a quote, not the final word.
Frequently asked questions
How do I calculate a fair price for a freelance project?
Start with your hourly rate multiplied by your best estimate of the hours the project will take. Then add a buffer — usually 15–25% — for revisions, meetings, and scope creep, and add any out-of-pocket expenses on top. The formula is: project price = hourly rate × hours × (1 + buffer ÷ 100) + expenses. That is exactly how this calculator prices your quote.
What buffer percentage should I add to my freelance quote?
Most freelancers add 15–25% as a buffer for the work that regularly takes longer than expected: client revisions, feedback rounds, meetings, and admin. Use 10–15% for simple, well-defined projects and 25–30% (or more) for complex projects, new clients, or tight deadlines. This calculator defaults to 25%, a safe middle ground.
Should expenses be added before or after the buffer?
Add expenses after the buffer, which is what this calculator does. Your buffer covers your time risk — the extra hours you end up working — not third-party costs like stock assets, travel, software, or subcontractors. Applying your buffer to someone else's costs would overcharge the client, so the buffer applies only to your labor: price = (rate × hours × (1 + buffer)) + expenses.
Is this calculator's number a binding price or just an estimate?
It is an estimate to guide your quote, not a binding contract. The result is only as good as your hour estimate — underestimate your hours and you will undercharge even with a buffer. Use the day-rate equivalent as a sanity check: if the per-day figure looks far off what your market pays, revisit your hourly rate before sending the proposal.
