When running Retirement Analysis to determine life insurance needs, does Right Capital factor in social security survivor benefits benefits?

Yes. It even automatically doesn't include it if you wouldn't qualify.

Thanks. How can I see the breakdown of which income sources it's including?

From memory it would be... Retirement menu Cash low sub menu Then maps and you can see a year by year play by play. You will also have a drop down at the top you can switch to breakdown if you want a further break down
