// Calculation Logic
// 1. Calculate Total Annual Expenses
var annualExpenses = monthlyExpenses * 12;
// 2. Calculate Gross Revenue Needed
// Formula: (Target Net / (1 – TaxRate)) + Expenses
// Logic: You pay expenses pre-tax (mostly), but you pay tax on the profit.
// Profit = Revenue – Expenses. Tax = Profit * Rate. Net = Profit – Tax.
// Net = (Revenue – Expenses) * (1 – Rate)
// TargetNet / (1 – Rate) = Revenue – Expenses
// Revenue = (TargetNet / (1 – Rate)) + Expenses
var taxDecimal = taxRate / 100;
var requiredProfit = targetIncome / (1 – taxDecimal);
var grossRevenue = requiredProfit + annualExpenses;
// 3. Calculate Total Working Hours
var workingWeeks = 52 – weeksOff;
var totalBillableHours = workingWeeks * billableHours;
// 4. Calculate Hourly Rate
var hourlyRate = grossRevenue / totalBillableHours;
// Display Results

Understanding Your Freelance Hourly Rate
Setting the right hourly rate is one of the most critical challenges for freelancers, consultants, and independent contractors. Unlike a salaried employee, your hourly rate must cover not just your desired take-home pay, but also your business expenses, taxes, and unbillable time.
Many new freelancers make the mistake of simply dividing their desired salary by 2,080 (the standard number of working hours in a year). This approach often leads to burnout and financial struggle because it fails to account for the overhead of running a business.
Key Factors in the Calculation
Billable vs. Non-Billable Hours: You cannot bill for every hour you work. Time spent on marketing, invoicing, administration, and learning is "non-billable." If you work 40 hours a week, you might only be able to bill clients for 20 to 25 of those hours.
Business Expenses: Software subscriptions, hardware, internet, home office costs, and professional insurance must be covered by your revenue before you pay yourself.
Taxes: As a freelancer, you are often responsible for both the employee and employer portion of taxes (self-employment tax). A safe buffer is usually 25-30% of your net profit.
Time Off: Paid time off doesn't exist for freelancers. If you want to take a vacation or need sick days, your hourly rate during working weeks must be high enough to cover the gaps in income.
How to Use This Result
The rate calculated above is your floor price—the minimum you need to charge to meet your financial goals. Depending on your industry, experience level, and the value you provide to clients, you should aim to price yourself above this floor to generate profit for business growth and savings.
