Social Security payments to surviving spouse

How much does social security pay a widow when her husband passes away? He was the primary income earner and she is not employed.

It’s based on how much he made. They have a calculator:

She gets either her SS pay or her husband’s, whichever is the greater.

She gets nothing unless she is at least 60 years of age, or “disabled” and 50 years of age.
