Calculate a project price from estimated hours, your hourly rate, and fixed expenses.
This tool calculates a suggested fixed-price project quote as estimated hours × hourly rate, plus any fixed expenses you enter -- a common way of converting hourly work into a fixed-price quote. There is no percentage buffer field; if you want to allow for scope creep, pad the hours or the expenses yourself.
Enter your estimated hours, your hourly rate, and your fixed expenses. The suggested project price appears instantly.
This calculator has three inputs: estimated hours, your hourly rate in dollars, and fixed expenses in dollars. The suggested project price is simply hours multiplied by rate, plus the fixed expenses. Negative entries are treated as zero. There is no percentage buffer field, so if you want contingency, you build it into the hours estimate (or the rate) yourself, or run the calculator a second time with a higher hours figure.
Project price = (estimated hours x hourly rate) + fixed expenses
Imagine a small website project with hypothetical numbers. You estimate 20 hours of work at 50 dollars per hour, and you know you must pay 100 dollars for a stock font license and a plugin. The labor portion is 20 x 50 = 1,000, and adding 100 of expenses gives a suggested price of 1,100 dollars. If you are worried about revision rounds and want roughly a 15 percent cushion on your time, you could enter 23 hours instead of 20. The labor becomes 1,150 and the price 1,250. That padding is your decision, not something the tool adds automatically.
The result is a starting point for a quote, not a guarantee of profit. It does not add sales tax or value-added tax, payment processing fees, self-employment or income taxes, or a margin for the risk that the client changes the scope. If you invoice across borders, currency conversion costs may also apply. The tool assumes a single blended rate, so a project that mixes premium work with routine tasks may need to be priced in parts. If your quote will be part of a contract, agree in writing what is included, how many revision rounds the price covers, and what additional changes will cost per hour. For tax questions that affect how you set rates, a qualified accountant or your national tax agency is the right source.
Fixed prices work well when the scope is clear and you are confident in your estimate; they reward efficiency because finishing early raises your effective hourly rate. They are risky when requirements are vague, because extra work comes out of your pocket. If the scope is uncertain, consider hourly billing, a not-to-exceed cap, or splitting the project into phases with separate quotes. After the project ends, compare your estimate with actual time spent; that habit is the best way to make future quotes more accurate. The Freelancer Profit Calculator on this site can help you look at what a finished project actually left you with after expenses and tax.
Fixed-price projects carry the risk that actual hours run over your estimate -- adding a cushion (commonly 10-25%) to the hours you enter helps protect your effective hourly rate if that happens. The tool itself does not add a buffer automatically.
No. It multiplies hours by rate and adds fixed expenses. To include a cushion, raise the hours you enter or use a slightly higher rate.
Only if they are specific to this project. General overhead that you carry every month is usually better reflected in your hourly rate than added to one quote.
No. Sales tax, VAT, and income taxes are not calculated here. Check with your tax authority or an accountant about what applies to your invoices.
Enter 0 to see the labor-only price, then rerun the calculation once you have quotes from vendors or subcontractors.
