}
// Step C: Base Revenue Needed (Income + Expenses)
var baseRevenue = preTaxIncomeNeeded + annualExpenses;
// Step D: Add Profit Margin
// Revenue = Base / (1 – Margin)
var decimalMargin = profitMargin / 100;
var totalRevenueNeeded = 0;

// 4. Update UI

// Main Rate

// Breakdown Stats
var dailyTarget = hourlyRate * (billableHours / 5); // Approx daily
var weeklyTarget = hourlyRate * billableHours;
document.getElementById('fhc_daily_target').innerText = '$' + dailyTarget.toFixed(2);
document.getElementById('fhc_weekly_target').innerText = '$' + weeklyTarget.toFixed(2);
document.getElementById('fhc_annual_gross').innerText = '$' + totalRevenueNeeded.toLocaleString('en-US', {minimumFractionDigits: 2, maximumFractionDigits: 2});

How to Calculate Your Freelance Hourly Rate
Determining the correct hourly rate is one of the most significant challenges for freelancers, consultants, and independent contractors. Unlike a traditional salary where taxes, insurance, and overhead are often handled by the employer, a freelancer must account for every cost of doing business within their rate.
This Freelance Hourly Rate Calculator uses a "reverse-engineering" approach. Instead of guessing a number, we start with your desired lifestyle and income goals, add your business costs and taxes, and divide by the actual time you spend working on billable tasks.
Key Factors in Your Rate Calculation
Billable vs. Non-Billable Hours: You cannot bill for 40 hours a week if you spend 10 hours on marketing, invoicing, and emails. Most successful freelancers only bill 50-70% of their total working time.
The Tax Wedge: As a freelancer, you are responsible for the full tax burden (including self-employment tax in many jurisdictions). Failing to buffer for this can lead to a lower net income than expected.
Unpaid Time Off: You don't get paid vacation or sick days. To maintain your annual income goal, your hourly rate must be higher to subsidize the weeks you are not working.
Profit Margin: A business should not just "break even" on salary and expenses. Adding a profit margin allows you to reinvest in better equipment, training, or save for lean months.
Formula Breakdown
To understand the math behind the calculator, here is the simplified formula used:
(Desired Net Income + Taxes + Business Expenses + Profit) ÷ Total Billable Hours = Minimum Hourly Rate
Why is my rate higher than I expected?
New freelancers are often shocked by the result. If you want to earn a net $50,000 (similar to a salary), you might need to charge $60-$80/hour depending on your expenses and billable hours. This "premium" covers the risk, overhead, and lack of benefits associated with freelance work. Use this number as your floor price—never go below it, and aim to charge more based on the value you provide to the client.
