Step-by-Step Examples

Example 1

Standard US Employee

Salary 75,000, taxes 7.65%, benefits 9,600, retirement 4%, insurance 1,800, overhead 4,200, 20 PTO days.

Taxes = 75,000 × 7.65% = 5,738
Retirement = 3,000
Additional = 5,738 + 3,000 + 9,600 + 1,800 + 4,200 = 24,338
Burden rate = 24,338 / 75,000 = 32.5%
Total cost = 99,338

✓ 32.5% burden, 99,338 total

Example 2

Minimal Benefits

Salary 50,000, taxes 7.65%, no benefits, no retirement, insurance 1,200, overhead 2,000.

Taxes = 3,825
Additional = 3,825 + 1,200 + 2,000 = 7,025
Burden rate = 14.1%
Total cost = 57,025

✓ 14.1% burden, 57,025 total

Example 3

Rich Package

Salary 140,000, taxes 7.65%, benefits 22,000, retirement 8%, insurance 3,000, overhead 8,000.

Taxes = 10,710, retirement = 11,200
Additional = 10,710 + 11,200 + 22,000 + 3,000 + 8,000 = 54,910
Burden rate = 39.2%
Total cost = 194,910

✓ 39.2% burden, 194,910 total

Real-World Applications

💰

True Hiring Cost

Base salary typically understates actual employment cost by 25 to 40%, which matters enormously in budgeting.

💲

Pricing and Rates

Service businesses must recover fully loaded cost, not salary, when setting billing rates or project pricing.

⚖️

Contractor Comparison

Comparing a contractor rate against a salary rather than loaded cost systematically makes contractors look expensive.

📊

Budget Accuracy

Headcount plans built on salary alone routinely run 30% over budget once burden is applied.

Common Mistakes to Avoid

⚠️

Budgeting on base salary alone

Burden typically adds 25 to 40% on top. A headcount plan built on salaries will be substantially under-budgeted.

⚠️

Forgetting the payroll tax wage base

Social security tax applies only up to an annual wage cap, so the effective tax percentage falls for high earners. Applying a flat rate overstates cost at the top end.

⚠️

Omitting non-obvious overhead

Software licences, equipment, workspace, recruiting amortisation, and training all belong in fully loaded cost but are frequently left out.

Frequently Asked Questions

What is payroll burden rate? ▾

The additional cost of employing someone beyond base salary — taxes, benefits, insurance, and overhead — expressed as a percentage of that salary.

What is a typical burden rate? ▾

Commonly 25 to 40% in the US depending on benefits generosity, with minimal-benefit roles lower and rich packages higher.

What should be included? ▾

Employer payroll taxes, health and other benefits, retirement contributions, workers compensation, unemployment insurance, equipment, software, and workspace.

How does burden affect billing rates? ▾

Service businesses must cover fully loaded cost plus overhead plus margin. Billing at a multiple of salary rather than loaded cost erodes profitability.

Does burden rate differ by seniority? ▾

Yes. Payroll tax caps mean the percentage often falls for high earners, while richer benefits and equipment can push it back up.
