The State Formula Rate

This page explains how to calculate your MIT pay during a leave at the state formula rate.

About the State Formula Rate

When leaves are paid at the state formula rate, the payment is calculated based on a formula applied to the staff member's actual past wages. In 2024, the maximum weekly benefit rate is $1,149.90.

The Massachusetts Department of Family and Medical Leave (which oversees the PFMLA) has an online calculator that allows employees to estimate the amount of gross pay they will be paid under the state formula, based on the employee’s earnings over the prior four quarters. This calculator is a helpful tool for employees looking to see what their rate of pay would be for any MIT medical or family leave that is paid at the state formula rate. Because the calculator only provides an estimate, the final gross amount may differ.

Deductions will be taken from the gross pay at the state formula rate for items like taxes, your share of health premiums, and other deductions regularly taken from your paycheck. Deductions that are based on a percentage of pay, like a 401(k) contribution, will be reduced if your paycheck is reduced because you are paid at the state formula rate.

Calculating Your MIT Pay at the State Formula Rate

1. Gather your paystubs from the last four completed quarters prior to your leave

When leaves are paid at the state formula rate, the payment is calculated based on a formula applied to the MIT employee's actual past wages and NOT the current salary/hourly rate. In order to use the calculator provided by the state, you will need to gather information from your historical paystubs. Visit About Me in Atlas to find your paystubs.

The paystubs you will need are those paid on the last pay date of a quarter. These would be the last paystubs in March, June, September and December.

Which quarters to use is dependent upon when you will be out on leave and should include the last 4 completed quarters. For example, if a leave begins in March 2023, the last 4 completed quarters would be the last pay date in the months of March 2022, June 2022, September 2022, and December 2022.

2. Find the YTD total gross on the paystub for each of the last four completed quarters

Your paystubs show the current period gross pay and the year-to-date gross pay, so you will need to calculate the quarterly amount based on the year-to-dates.

Here is an example showing the section of the stub you need.

Pay Date Example
3. Use those numbers to find your quarterly gross
Pay date A. Total gross B. Gross at end of prior quarter Quarterly gross (A - B)
12/30/22 $56,567.75 $43,289.35 $13,278.40
09/30/22 $43,289.35 $28,881.64 $14,407.71
06/30/22 $28,881.64 $14,227.20 $14,654.44
03/31/22 $14,227.20 N/A $14,227.20
4. Use the state's online calculator to find your pay at the state rate during your leave

Once you have your last four completed quarters, go to the state provided online calculator and enter your information.

The result will be a weekly rate that will be used to determine a semi-monthly amount or hourly rate which are MIT’s pay categories. In this example, the weekly rate calculated by the state is $823.80.

Converting the weekly rate to semi-monthly or hourly

To calculate an estimated semi-monthly rate:

$823.80 x 52 weeks = $42,837.60 / 24 pay periods = $1,784.90

To calculate an estimated hourly rate:

$823.80 / # of hours per week for the employee

Presume an employee works 40 hours per week

$823.80 / 40 hours = $20.60/hour
