Survivor Benefit Calculation used by your Software
When calculating the Survivor Benefit in your software, please clarify if you use the full Option A/Option B calculations as listed in Doug Runchey's definitive article "Understanding the CPP's Survivor Benefit" dated February 8, 2023 (website https://retirehappy.ca/cpp-survivor-benefits/ ).
The Option B calculation normally reduces what you might expect under the 60% rule down to 36% - I know because that happened to me when my wife died some years ago but Doug kindly confirmed my calculations so I knew what to expect ahead of time and could plan accordingly. Of course the other main limitation is that you will never receive more than the maximum CPP benefit, especially limiting if you are almost at the maximum based on your own contributions.
