Setting the right hourly rate is one of the most challenging aspects of freelancing. If you set it too low, you risk burnout and financial instability. If you set it too high without justification, you might struggle to attract clients. This calculator helps you work backward from your financial goals to determine exactly what you need to charge to sustain your lifestyle and business.
The Formula Behind the Calculation
Unlike a salaried employee, a freelancer's hourly rate must cover not just their take-home pay, but also business expenses, taxes, health insurance, unpaid vacation time, and unbillable hours. The core formula used in this calculator is:
(Desired Annual Income + Annual Expenses + Profit Buffer) ÷ Total Billable Hours = Minimum Hourly Rate
Key Factors to Consider
Billable vs. Actual Hours: You might work 40 hours a week, but you likely can't bill for all of them. Administrative tasks, marketing, invoicing, and learning new skills are "unbillable." A realistic billable target is often 20-30 hours per week.
Expenses & Overhead: Don't forget software subscriptions, hardware upgrades, internet costs, co-working space fees, and professional insurance. These must be factored into your revenue targets.
Time Off: Salaried employees get paid vacation and sick leave. Freelancers do not. If you plan to take 2 weeks of vacation and account for 1 week of potential sick days, you are only earning revenue for 49 weeks of the year.
Example Calculation
Let's say you want to earn a gross personal income of $80,000 per year.
Expenses: You have $5,000 in annual business costs.
Buffer: You want a 10% safety margin ($8,500).
Total Revenue Needed: $93,500.
Time: You plan to work 48 weeks a year, billing 25 hours a week. That is 1,200 billable hours.
Your calculation would be: $93,500 ÷ 1,200 hours = $77.92/hour.
In this scenario, rounding up to $80/hour or even $85/hour ensures you meet your goals comfortably.
Why You Should Add a Profit Buffer
The "Profit Margin/Buffer" field in this calculator allows you to add a percentage on top of your base costs. This is crucial for business growth. It provides capital to reinvest in your business (e.g., hiring an assistant, buying better equipment) or simply acts as a safety net for lean months where client work might slow down.

// 2. Calculate Total Billable Hours
var totalBillableHours = workingWeeks * hours;
// 3. Calculate Total Financial Requirement
var baseRequirement = income + expenses;
// 4. Add Profit Margin
var totalRevenueNeeded = baseRequirement * (1 + (margin / 100));
// 5. Calculate Hourly Rate
var hourlyRate = totalRevenueNeeded / totalBillableHours;
// 6. Calculate Daily Rate (assuming standard 8h availability,
// even if not all are billable, but usually daily rate is hourly * 8 or hourly * billable per day)
// For this calc, let's assume a "Day Rate" is simply Hourly * 8 as a standard industry benchmark
var dailyRate = hourlyRate * 8;
// Formatting currency
var formatter = new Intl.NumberFormat('en-US', {
style: 'currency',
currency: 'USD',
minimumFractionDigits: 2,
maximumFractionDigits: 2

// Update DOM
