Understanding the W2 vs 1099 Calculation
Switching from a full-time salaried employee (W2) to an independent contractor (1099) involves more than just dividing your annual salary by 2,080 working hours. To maintain the same standard of living, you must account for the "hidden paycheck" your employer provides in the form of benefits, tax contributions, and paid time off.
The Self-Employment Tax Burden
As a W2 employee, your employer pays half of your FICA taxes (Social Security and Medicare), totaling 7.65% of your wages. As a 1099 contractor, you are responsible for the full 15.3%. Our calculator adds this 7.65% differential to your target revenue to ensure your net take-home pay remains comparable.
Accounting for Benefits
Health insurance, 401(k) matching, bonuses, and paid time off often amount to 20% to 35% of a base salary. When you contract, you lose these perks. You must increase your hourly rate to cover the cost of purchasing your own insurance and funding your own retirement. The default setting in this calculator adds a 30% premium to cover these costs, but you can adjust this based on your specific industry standards.
Billable vs. Non-Billable Hours
A standard employee works roughly 2,080 hours a year (40 hours x 52 weeks). However, contractors rarely bill for every hour they work. You must account for:
- Unpaid Vacation/Sick Time: If you don't work, you don't get paid.
- Admin Time: Invoicing, marketing, and finding new clients are essential but unpaid tasks.
This calculator determines your rate based on your actual billable hours after deducting weeks off for holidays, vacation, and sick time.
The General Rule of Thumb
Many experts suggest a rule of thumb where your 1099 hourly rate should be at least 1.5x to 2x your equivalent W2 hourly wage. This markup provides a safety net for the instability of contracting work and covers the additional overhead of running your own business.

// Get Input Values
var salary = parseFloat(document.getElementById('w2_salary').value);
var benefitsPct = parseFloat(document.getElementById('benefits_pct').value);
var expenses = parseFloat(document.getElementById('annual_expenses').value);
var weeksOff = parseFloat(document.getElementById('weeks_off').value);

// Validation

if (isNaN(hoursPerWeek)) hoursPerWeek = 40;
// Logic: Calculate Total Revenue Needed
// 1. Benefits Cost
var benefitsCost = salary * (benefitsPct / 100);
// 2. Self Employment Tax Differential
// Employer usually pays 7.65% FICA. As a contractor, you pay this extra amount yourself.
// We add this to the total needed so the net outcome is similar.
var taxDifferential = salary * 0.0765;
// 3. Total Annual Revenue Target
var totalRevenueNeeded = salary + benefitsCost + taxDifferential + expenses;
// Logic: Calculate Billable Hours
var workingWeeks = 52 – weeksOff;
if (workingWeeks 0) {
hourlyRate = totalRevenueNeeded / totalBillableHours;
