FreelanceCalc is a free collection of tax and finance calculators built specifically for freelancers, 1099 contractors, gig workers, and other self-employed professionals in the United States.
The idea came from a simple, common frustration: most online tax calculators are built for W2 employees, and the few that target freelancers often oversimplify the math in ways that lead to underpaying or overpaying. Self-employment tax, quarterly estimated payments, and the deductions available to independent contractors all work differently than a typical paycheck calculator assumes.
There are eight calculators covering the most common financial questions freelancers run into: estimating quarterly taxes, comparing 1099 income to a W2 salary, figuring out what hourly rate to charge, building quick invoices, calculating late payment fees, checking whether a project is actually profitable, and tracking two of the most commonly missed deductions — mileage and home office expenses.
Every calculation happens directly in your browser using standard JavaScript. Nothing you type is sent to a server, logged, or stored anywhere — you can close the tab and your information is gone. There's no account to create and no email required to use any tool on this site.
These tools are built using publicly available IRS guidance and standard tax formulas, and are intended for estimation and planning purposes. They are not a substitute for advice from a licensed CPA or tax professional, particularly for situations involving state taxes, multiple income streams, or more complex business structures. See the disclaimer for more detail.
This site is built and maintained independently. If you find a calculation that looks wrong or have a suggestion for a new tool, feedback is always welcome.
