Formula Used
Gross Pay = Base Pay + Bonus Pay + Overtime Pay
Taxable Payroll Wages = max(0, Gross Pay − Payroll-Tax Exclusions)
Capped Payroll Tax = min(Current Taxable Wages, Remaining Wage Cap) × Rate
Remaining Wage Cap = max(0, Wage Cap − Year-to-Date Subject Wages)
Medicare or Local Payroll Tax = Taxable Payroll Wages × Rate
Workers Compensation = Gross Pay × (Workers Compensation Rate per 100 ÷ 100)
Retirement Match = Gross Pay × Retirement Match Rate
Training Levy = Gross Pay × Training Levy Rate
Employer Burden = Sum of employer taxes, levies, benefit contributions, and other deductible employer expense
Total Deductible Compensation Cost = Gross Pay + Employer Burden
Annualized values assume the current pay pattern repeats across the selected pay frequency.

Frequently Asked Questions
1. What does this calculator estimate?
This calculator estimates employer-side payroll taxes, benefit contributions, levies, and other deductible payroll-related expenses for one pay period and an annualized view.
2. Does it calculate employee withholding too?
No. It focuses on employer costs and deductible compensation expense, not employee withholding, take-home pay, or personal tax liability.
3. Why are there YTD wage fields?
Year-to-date wages help the calculator apply capped taxes more realistically. Once a cap is reached, that component stops or reduces for the rest of the year.
4. What are payroll-tax exclusions?
They are current-period amounts removed from taxable payroll wages. Examples may include items treated differently under your payroll rules or tax framework.
5. Why is workers compensation entered per 100 wages?
Many payroll teams price workers compensation using a rate per 100 of wages. The calculator converts that format into a period cost automatically.
6. Are the default rates final?
No. They are editable starter values for demonstration. Replace them with the rates, caps, and benefit costs that apply to your jurisdiction and payroll year.
7. How should I interpret annualized results?
Annualized results assume the current period repeats for every payroll cycle. Real annual totals can differ when wages, bonuses, caps, or benefits change later.
8. Can I use this for budgeting and scenario planning?
Yes. It works well for comparing compensation packages, payroll burden, benefit design choices, and forecasted deductible employment cost across scenarios.
