I’m turning 65 next year and currently receiving $1167 a month for CPP Disability, I read that the estimate of post-65 CPP benefits on Service Canada are underestimated because they include the years we receive CPP-D, while the actual post-65 CPP amount will not include the time we are on CPP-D. I also read that a quick way to calculate our post-65 CPP benefit amount is to take our monthly CPP-D payment amount, subtract the flat rate portion of our payment and divide the remainder by .75. Can anyone confirm that this method is correct?
According to the Canada Pension Plan Disability Toolkit, the flat rate for 2025 is $598.49. So, in my case I would have ($1167-$598.49)/.75=$758.01. This is significantly higher than the estimate shown on the Service Canada website.
Using a sample size of one, my regular CPP was within $1.00 of the estimated amount using the formula you quoted.
Also don’t forget you’ll also be eligible for OAS payments (max of $713/month, I think).
