mortgage net rate lock volume measures the unpaid principal balance of mortgage interest-rate lock commitments after expected fallout or pull-through adjustments.
Rocket Companies example
Rocket Companies reported $132.005 billion of net rate lock volume for 2025.
How it fits the origination funnel
A rate lock sits upstream of a closed mortgage. Rocket defines net rate lock volume using the unpaid principal balance of interest-rate lock commitments after applying its pull-through assumptions. Comparing lock volume with closed-loan volume helps investors see how much locked pipeline converted into funded production.
Investor caution
Net rate lock volume is not revenue, funded principal, or a guaranteed future closing. Pull-through assumptions, borrower fallout, market rates, channel mix, and timing can all change the bridge from locked volume to closed loans.
