After an employer has paid wages for a sufficient number of quarters, it is eligible for a computed rate based on the experience of the business.
The formula for a computed rate is:
Total Premiums Paid in to the account minus Total Benefits Charged to the account divided by the Average Chargeable Payroll. The result of this formula is the percent of excess.
Look for the percent of excess in the left hand column of the rate chart and follow that line to the right across the chart to the column heading “Reserve Ratio .006-.008”. The point of intersection is the base rate for 2015.
(Rates for years prior to 2013 used a different rate chart with columns based on the level of the Unemployment Insurance Trust Fund on any June 30.)
