How This Calculator Works

Calculation methodology and assumptions

Montana's employer guide allows a flat 5% on supplemental wages paid separately, or a calculation combining them with current or prior payroll-period wages. Confirm how payroll classifies the award and which method it uses; the input is adjustable.

Frequently Asked Questions

Must Montana payroll use the flat option?

For separately paid supplemental wages, the guide also offers calculations combining them with current or prior regular pay. Ask payroll which applies to your award.

Does the estimate allocate a multistate award?

No. Enter a state percentage that reflects your own circumstances; the calculator does not apportion compensation for work in different states.
