CPP disability after 65

Hi,
I understand from the federal government website that the CPP disability benefit automatically converts to a CPP retirement benefit afterage 65 and will be less than the disability benefit. Can’t find out how much less. Do you know how this is calculated?
many thanks, Ralph

Did you check your Service Canada account? It shows all the amounts there.

I think those are just estimates but they give a relative approximation.
My estimates are about 67%.
