// 3. Validation
if (isNaN(netIncome) || netIncome < 0) netIncome = 0;

// 4. Calculate Logic
// Calculate total working weeks
var workingWeeks = 52 – weeksOff;
if (workingWeeks <= 0) workingWeeks = 1; // Prevent division by zero or negative time
// Calculate total billable hours per year
var totalAnnualHours = workingWeeks * billableHours;
// Calculate Gross Revenue needed to cover Net Income + Expenses
// Formula: Net = (Gross – Expenses) * (1 – TaxRate)
// Inverted: Gross = (Net / (1 – TaxRate)) + Expenses?
// More Accurate Freelance Logic: You need to pay taxes on the TOTAL Gross.
// Gross = (Net + Expenses) / (1 – TaxRate) — Assuming expenses are not tax deductible?
// Usually expenses ARE deductible.
// Better Formula:
// TaxableIncome = Gross – Expenses
// Net = TaxableIncome * (1 – TaxRate)
// Net = (Gross – Expenses) * (1 – TaxRate)
// Net / (1 – TaxRate) = Gross – Expenses
// Gross = [Net / (1 – TaxRate)] + Expenses
var taxDecimal = taxRate / 100;
var divisor = 1 – taxDecimal;
if (divisor <= 0) divisor = 0.01; // prevent divide by zero if 100% tax
var requiredPreTaxIncome = netIncome / divisor;
var grossRevenue = requiredPreTaxIncome + expenses;
// Calculate Hourly Rate
var hourlyRate = grossRevenue / totalAnnualHours;
// Calculate Sub-metrics
var monthlyRevenue = grossRevenue / 12;
var weeklyRevenue = grossRevenue / workingWeeks; // Revenue needed per WORKING week
// 5. Update UI
// Format Currency
var formatter = new Intl.NumberFormat('en-US', {

How to Calculate Your Freelance Hourly Rate
Setting the right hourly rate is one of the most challenging aspects of freelancing. Price yourself too low, and you risk burnout and financial instability; price yourself too high without justification, and you may struggle to attract clients. The Freelance Hourly Rate Calculator above takes the guesswork out of pricing by using a "bottom-up" approach based on your financial needs.
Unlike a salaried employee who receives a predictable paycheck with taxes withheld and benefits provided, a freelancer must generate enough revenue to cover salary, overhead expenses, taxes, and non-billable time. This guide explains the critical factors incorporated into our calculator.
1. Net Income vs. Gross Revenue
Your "Net Income" is the actual money you want to take home—your salary. However, to achieve a net income of $75,000, you cannot simply bill $75,000. You must bill significantly more to cover:
Business Expenses: Software subscriptions, hardware, internet, home office costs, and insurance.
Self-Employment Taxes: In many jurisdictions, freelancers pay both the employer and employee portion of social security and medicare taxes, plus income tax.
2. The Myth of the 40-Hour Billable Week
One of the most common mistakes new freelancers make is assuming they will bill 40 hours a week. In reality, a significant portion of your week is spent on unbillable tasks, such as:
Marketing and finding new clients
Administrative work (invoicing, contracts)
Skill development and training
Most successful freelancers aim for 20 to 30 billable hours per week. Our calculator asks for your "Billable Hours" to ensure your rate covers your entire work week, not just the time spent on client projects.
3. Accounting for Time Off
Freelancers do not get paid time off (PTO). If you want to take 2 weeks of vacation and allow for 2 weeks of potential sick time, you are only generating revenue for 48 weeks of the year. Your hourly rate must be high enough during those 48 weeks to cover your expenses for the full 52 weeks.
Step-by-Step Calculation Formula
To understand the math behind the tool, here is the formula we use:
Calculate Working Time:(52 Weeks - Vacation Weeks) × Billable Hours/Week = Total Billable Hours
Calculate Gross Need:(Desired Net Income ÷ (1 - Tax Rate)) + Expenses = Total Revenue Needed
By using this formula, you ensure that every hour you bill contributes accurately to your lifestyle goals, tax obligations, and business sustainability.
When to Adjust Your Rate
Once you have your baseline number, consider market factors. If your calculated rate is $80/hr, but the market average for your skill set is $150/hr, you should increase your rate to match the value you provide. Conversely, if the market rate is lower, you may need to reduce expenses or increase your billable hours efficiency to make the numbers work.
