This spreadsheet, courtesy of Blum Shapiro, contains a loan forgiveness calculator for your PPP loan.
It has inputs for your total loan amount, the amount of approved payroll/mortgage/etc. payments, the amount of forgiveness reduction, and so on.
I have not checked all the calculations personally, but they seem sound.
I am unable to find guidance regarding payments for leased employees. Are the payments for Leased employees forgivable under the PPP loan guidelines? Thank you!
