What it is#
The incremental recovery rate measures the lift an intervention produces in a recovery outcome — reactivating lapsed customers, collecting overdue accounts, or winning back churned users — beyond what would have recovered anyway. It is the treated group’s recovery rate minus a control group’s:
Why the baseline matters#
A raw recovery rate overstates a campaign’s value, because some accounts self-cure or return without any nudge. Subtracting a holdout control isolates the causal lift — the recoveries the intervention actually caused — the same incrementality logic behind incremental sales and conversions.
Where it’s used#
IRR drives targeting and budget in collections, retention, and win-back — you focus effort on segments with the highest incremental recovery, not the highest raw recovery, since some of those would come back for free. It pairs naturally with uplift models that predict per-customer lift.
