I'm trying to figure out if there's an easy online calculator that allows one to input the combined income of husband and wife (both US citizens), the number of kids and then the number of adult siblings and their kids to find out if the income of the sponsoring family is sufficient?

- If one spouse has sponsored his siblings and now the other spouse wants to sponsor her siblings with kids, how should one look at the affidavit of support?

- I'm assuming that any sponsored individuals (regardless of when they were sponsored) should be included/counted when calculating the income sufficient for sponsoring more family members.

I know it's a little vague but let's start the conversation and we can keep adding details. Hoping this may help all future sponsors (especially who may have relatively large overseas families). Thank you for your help!
