UPB
Also known as: unpaid principal balance, outstanding principal balance
status: draft
Unpaid principal balance. The remaining principal owed on a loan or pool of loans at a given point in time. Used to measure pool size, calculate advance rates, and track amortization.
What to watch
UPB changes daily as borrowers pay down principal. For borrowing base calculations, the relevant figure is eligible UPB (loans meeting concentration limits and eligibility criteria). Distinguish between scheduled UPB (what remains if borrowers pay on schedule) and actual UPB (reflecting prepayments and delinquencies). Large gaps between the two signal performance divergence from underwriting.
