// Simplified Freelance Logic:
// Gross Needed to cover expenses + taxes + net target
// var G = Gross. Expenses E are deductible.
// Taxable Income = G – E
// Net Income = (G – E) – (TaxRate * (G – E))
// Net Income = (G – E) * (1 – TaxRate)
// TargetNet = (G – E) * (1 – Tax/100)
// TargetNet / (1 – Tax/100) = G – E
// G = [TargetNet / (1 – Tax/100)] + E
var taxFactor = 1 – (taxRate / 100);
if (taxFactor <= 0) taxFactor = 0.01; // Prevent division by zero if tax is 100%
var grossRevenueNeeded = (targetNet / taxFactor) + annualExpenses;

How to Calculate Your Freelance Hourly Rate Correctly
Setting the right hourly rate is one of the most critical decisions a freelancer or consultant makes. Set it too high, and you may scare off potential clients. Set it too low, and you risk burnout while barely covering your bills. This Freelance Hourly Rate Calculator helps you determine exactly what you need to charge to meet your financial goals while accounting for taxes, overhead, and time off.
Why You Can't Just Pick a Number
Many new freelancers make the mistake of taking their previous full-time hourly wage and adding a few dollars. This is a recipe for financial disaster. As an employee, your employer covered:
Payroll taxes (often 7.65% in the US for Social Security/Medicare)
Health insurance and benefits
Office equipment, software, and rent
Paid time off (vacation and sick days)
As a freelancer, you are responsible for all of these. To maintain the same standard of living, your freelance rate typically needs to be 2x to 2.5x your equivalent employee hourly wage.
Understanding Billable vs. Non-Billable Hours
The calculation above asks for your "Billable Hours per Week." This is crucial. If you work 40 hours a week, you cannot bill 40 hours. You must account for:
Marketing & Sales: Finding new clients and writing proposals.
Administration: Invoicing, bookkeeping, and taxes.
Skill Development: Learning new tools or techniques.
A realistic target for a full-time freelancer is often 20 to 30 billable hours per week. The calculator uses this reduced number to ensure your paid hours cover your unpaid administrative time.
The Tax Factor
Taxes are the biggest surprise for new self-employed individuals. In many jurisdictions, you must pay both the employee and employer portion of social security taxes (Self-Employment Tax), plus federal and state income taxes. A safe rule of thumb is to set aside 25% to 30% of your gross income for taxes. Our calculator reverses the math to show you the Gross Revenue needed to hit your Net (take-home) goal.
How to Use This Calculator
Target Net Income: Enter the amount of money you want to actually put in your bank account annually for personal use.
Expenses: Sum up your business subscriptions, internet, phone, co-working space fees, and hardware costs.
Capacity: Be honest about how many weeks you want to take off and how many hours you can realistically bill client work.
Use the resulting Minimum Hourly Rate as your baseline floor. When negotiating with clients, aim higher than this number to build a profit margin for business growth.
