Excluded wages are user-defined amounts removed from the taxable model for this estimate.

Formula used

Current Taxable Wages = max(0, Current Wages + Bonus - Excluded Wages)

Employer Social Security Tax = min(Current Taxable Wages, SS Wage Base - YTD SS Wages) × SS Rate

Employer Medicare Tax = Current Taxable Wages × Medicare Rate

Effective FUTA Rate = max(0, FUTA Gross Rate - FUTA Credit)

FUTA Tax = min(Current Taxable Wages, FUTA Wage Base - YTD FUTA Wages) × Effective FUTA Rate

SUTA Tax = min(Current Taxable Wages, SUTA Wage Base - YTD SUTA Wages) × SUTA Rate

Local Payroll Tax = Current Taxable Wages × Local Payroll Tax Rate

Workers Comp Burden = (Current Taxable Wages ÷ 100) × Workers Comp Rate

Total Employer Burden = Social Security + Medicare + FUTA + SUTA + Local Payroll Tax + Workers Comp

Effective Employer Rate = Total Employer Burden ÷ Current Taxable Wages

Frequently asked questions

1) What payroll costs does this estimate include?

It estimates employer Social Security, employer Medicare, FUTA, SUTA, local payroll tax, and workers comp style payroll burden. Each rate and wage cap is editable, so the model can match many payroll setups.

2) Does it apply annual wage caps automatically?

Yes. The calculator compares current taxable wages with the remaining room under each wage base. If an employee already crossed a cap, that tax component drops to zero for the current estimate.

3) Can I estimate several employees at once?

Yes. Paste one employee per line in the batch textarea. The calculator processes each line separately, then adds every tax component into one employer summary for the pay period.

4) Are bonuses included in the calculation?

Yes. Bonuses are added to current wages before excluded amounts are removed. This makes it easier to test bonus payroll runs and see how caps affect employer taxes.

5) What are excluded wages in this model?

Excluded wages are user-defined amounts removed from taxable pay in this estimate. They help when you need a planning model for wages that should not be taxed under your chosen setup.

6) Why is there a FUTA credit field?

Many teams prefer entering FUTA as a gross rate and then reducing it by a credit. The calculator subtracts the credit and never lets the effective FUTA rate fall below zero.

7) Is this enough for payroll filing?

No. This page is a planning and budgeting tool, not a filing engine. Always confirm current rules, account-level experience rates, deposit schedules, and payroll system settings before submitting official returns.

8) When is this calculator most useful?

It works well for budgeting, hiring plans, location comparisons, bonus forecasting, and payroll cost reviews. You can test assumptions quickly and see how taxes shift when wages or rate settings change.
