Calculate your 12-month average revenue drop

Your 12-month average revenue drop is the average of your applicable monthly revenue drops from March 2020 to February 2021 (CEWS claim period 1 to 13, excluding either claim period 10 or 11).

When to calculate the 12-month average revenue drop

You only need to calculate the 12-month average revenue drop one time. You use the same 12-month average revenue drop for all of your claims from period 22 onward.

For details on the math behind the calculation, refer to how the 12-month average revenue drop is calculated.

Differences between the 12-month average revenue drop and the claim period revenue drop calculations

Include revenue increases

You must include revenue for all months between March 2020 and February 2021 that relate to claim periods during which you either operated or were not operating due to a public health restriction. This means if any of the months you calculate had a revenue increase instead of a drop, you must include it as part of your 12-month average calculation.

Deeming rule does not apply

Unlike the claim period revenue drop, there is no deeming rule provision for the 12-month average revenue drop that allows you to use the better of two rates. You must include the actual revenue drop calculation for each reference period.

Must exclude months when not operating

If you were not operating for any length of time in any of claim periods 1 to 13, you must exclude the corresponding reference month from the 12-month average revenue drop, unless the reason for not operating was due to a public health restriction, in which case you must include the month in your calculation. An example of you not operating throughout a claim period would be in the case of a seasonal closure.

As the reference month for both claim periods 10 and 11 is December, you only need to exclude December if you were not operating throughout both claim periods.
