What are your possible MAP savings?

The WSIB has a program to encourage small businesses (those with average yearly premiums under $25,000) to prevent workplace injuries. The Merit Adjusted Premium Plan (MAP) gives employers a premium adjustment increase or decrease based on their injury rates.

Fill in the input fields below to calculate the maximum savings and maximum surcharges for your WSIB premiums. You may find that preventing injuries could save you money!

Please note that this calculation is not an estimate or your actual MAP rate adjustment. This calculator demonstrates the difference between best and worst case scenarios based on a one-year period.

Note: It is possible to be targeted for a Workwell audit (a division of the WSIB) or a Ministry of Labour visit even if you receive a MAP rebate (due to differing criteria for poor performance). A Workwell audit penalty can cost you up to 75% of your average yearly premium assessment.

Preventing workplace injuries is the best way to avoid debits and other costs.
