What happens if you use less than 60% of the loan on payroll?

If a person uses less than 60% of the funds toward payroll expenses, the total amount of potential loan forgiveness will be reduced to the point where the 60% threshold has been met. For example

PPP loan amount = $100,000.00
Payroll Expenses = $50,000.00
Non-Payroll Expense = 40,000.00

The original 60% threshold required at least 60,000 to be spent on Payroll.
Since we only spent $50,000.00 on payroll our max loan amount that would meet the loan threshold would have been $50,000/0.60 = $83,333.33

Based on the max loan forgiveness amount: $83,333.33
Payroll Expenses: $50,000.00
Non-Payroll Expense: $33,333.33
