How to use this tool

  1. Enter the employee base salary you are comparing.
  2. Set the benefits/overhead load you must now self-fund (often 25–40%).
  3. Set the extra payroll tax you cover yourself (US default 7.65%).
  4. Enter your realistic billable hours, then read the equivalent contractor rate.

Thinking of leaving a salaried job to contract — or quoting a client who used to employ you? Convert the salary into the equivalent contractor hourly rate by grossing it up for benefits and self-paid taxes, then dividing by the hours you can actually bill.

Formula

Grossed-up value = Salary + Salary × Benefits load + Salary × Extra payroll tax

Equivalent contractor rate = Grossed-up value ÷ Billable hours per year

A contractor must replace the value of employer-paid benefits and pay the employer half of payroll tax themselves, so the equivalent rate is well above salary ÷ 2,080.

How it works

Comparing a salary to a contract rate is not as simple as dividing by hours worked. An employee receives a wage plus benefits the employer pays for — health insurance, a retirement match, paid leave, equipment, payroll-tax contributions. A contractor must self-fund all of that out of the headline rate. This calculator grosses the salary up by a benefits/overhead load and by the employer share of payroll tax, then spreads the total over the hours you can actually bill.

The benefits load is the lever that matters most: 25–40% is a common range once health coverage, retirement and paid time off are valued, but it varies widely by person and country, so it is an input. The extra payroll-tax field defaults to 7.65% — the US employer FICA share that a self-employed person covers through self-employment tax — and can be set to zero where it does not apply. Because contractors bill fewer hours than the 2,080 in a salaried year, a lower billable figure pushes the equivalent rate up.

Worked example

$100,000 salary, 30% benefits load, 7.65% extra tax, 1,500 billable hours

  1. Benefits/overhead added = 100,000 × 30% = 30,000.
  2. Self-paid payroll tax added = 100,000 × 7.65% = 7,650.
  3. Grossed-up value = 100,000 + 30,000 + 7,650 = 137,650.
  4. Equivalent rate = 137,650 ÷ 1,500 = 91.7667.

Equivalent contractor rate = $91.77

Key terms

Benefits load
The value of employer-paid benefits expressed as a percentage of salary, which a contractor must self-fund.
Employer payroll tax share
The portion of payroll (e.g. FICA) an employer normally pays; a self-employed person pays both halves.
Grossed-up rate
A salary scaled up to include benefits and taxes the worker now bears directly.
W-2 vs 1099
In the US, W-2 denotes an employee and 1099 an independent contractor, with different tax and benefit treatment.

Frequently asked questions

Why is the contractor rate so much higher than salary ÷ 2,080?
Because a contractor self-funds benefits, pays the employer half of payroll tax, and bills fewer than 2,080 hours. Grossing the salary up and dividing by real billable hours captures all three effects.
What benefits load should I use?
A practical range is 25–40% of salary, covering health coverage, retirement contributions, paid leave and equipment. Value your own benefits and adjust; if your old job had rich benefits, use a higher figure.
Is the 7.65% always right?
It reflects the US employer share of Social Security and Medicare that self-employed people cover. Outside the US, or if you model self-employment tax separately, set it to zero or to your local figure.
