A loss-rate method estimates expected credit loss by applying a supported rate to a controlled exposure. The rate may begin with historical loss experience and then reflect current conditions, forecasts, reversion, and expected recoveries as required.
Show the rate bridge
For a $40,000 pool, assume a 4 percent historical rate, a 1 percentage-point current-condition adjustment, and a 1-point forecast adjustment:
Adjusted rate = 4% + 1% + 1% = 6%
Expected loss = $40,000 × 6% = $2,400
Keep every component visible. A reviewer should be able to trace the historical numerator and denominator, observation period, writeoff and recovery convention, pool definition, adjustments, and approval.
Reconcile before multiplying
Tie exposure to the gross receivable population. Confirm that credit balances, disputes, modified assets, purchased assets, and individually evaluated items follow their documented paths. Test whether one economic driver appears in both the historical base and an overlay.
Boundary and source
A mathematically correct rate can still be unsupported. It does not prove pool similarity, forecast quality, contractual term, or collection expectations. Read ASC 326-20-30-5 for loss-rate methods and ASC 326-20-30-8 for adjustments to historical loss information.
Put the concept to work

Apply this concept
- Compute pool-level adjusted rates and expected losses, aggregate the allowance, and reconcile exposure and loss totals without hiding overrides.
